Drawings of a miracle shovel. Choosing a miracle shovel for easy work in the garden. How to make a miracle shovel at home - a quick guide
Many gardeners and summer residents recommend using a miracle shovel for manual tillage. The wonder digging shovel has a special design to increase the speed of work with less loads. Its main task is not to turn over the earth, but to loosen it. According to many reviews, the thing is worth it. The principle of operation and design is not much more complicated than a conventional shovel - it is easy to make it yourself, having basic welding skills.
- suitable for any soil;
- significantly reduces physical activity;
- easy to use;
- increases the speed of digging;
- has a high degree of reliability.
- The shovel is determined on the front ripper, holding it by the handle.
- The forks are stuck into the ground until the rear stop touches the ground. At this stage, the amount of effort applied directly depends on the type of soil, its hardness and workability.
- Further, the stalk is pulled "on itself". At this time, the forks begin to move upwards. As they rise, they pass through the front forks, breaking up clumps at the same time.
- For the next step, you need to drag the device back, and repeat all the steps. After a short training, the work comes to automatism, and much less effort is actually spent.
- square tube 10 mm;
- metal pipe from 5 cm;
- reinforcement or strip of alloyed rolled products not less than 50 mm thick and 2 cm wide;
- bolts and nuts;
- welding machine;
- drill;

What is the advantage of the miracle shovel?
First of all, it allows you to significantly increase the speed of work. Due to the special design, the load on the back when digging is much less, and the muscles almost do not get tired. There are several designs of the miracle shovel, but basically it is a combination of a pitchfork and a tool for loosening the earth.
In order to use the miracle shovel of the most common “mole” or “crotchel” design, you just need to stick the forks into the ground, as with ordinary digging, and put the device on the back stop. After that, the soil is gradually raised and loosened.
It is worth noting that it will be quite difficult for a man or woman weighing less than 80 kg to control the device. Also, it is not suitable for figured digging or digging a hole. Breakdown repair is quite difficult.
But these shortcomings are negligible compared to the positives:
Varieties of a shovel
There are several types of miracle shovel designs. They are conditionally divided into three types: a ripper with almost no front stop, a plowman-type design, and a mole-type design.
Some types of ripper without front stop have only working forks. For example, the "digger" option, which is simply a wide fork with a back stop. In this case, it is fixed on the frame not permanently, but movably. First, the pins are placed in the ground, after which they press on the stop and turn the ground out. When working with such a shovel exercise stress small, but it does not crush the soil like other designs. Instead, it can be used for digging potatoes as opposed to a shovel with two sets of pitchforks.
Additionally, the digger is equipped with an adjustable handle, which greatly simplifies the work process, but its design is much simpler and does not have the same efficiency as a miracle shovel with 2 pairs of forks. Another design "Lightcopper". It looks the same as the previous one, but does not have an adjustable handle. Equipped with working forks and movable stop.
The other two designs look similar. With only one exception, the plowman shovel has shorter fork teeth, which makes it more effective as a baking powder rather than a digger. The depth of the shovel bayonet in the "mole" design is more than 25 cm. There are also universal shovels with a bayonet length of 15-20 cm. The choice of a specific type depends on the depth of freezing of the soil and its type.
Features of use
Although the shovel looks simple on the outside, its work has its own characteristics. First of all, the basic rule is to move backwards. Therefore, they begin to dig from the far edge of the garden. The algorithm of actions is as follows:
Buy or make your own?
There are a lot of disputes about whether or not to purchase a miracle unit, since its price for a shovel is not so small - about 1.5 thousand rubles. It is worth noting that many factory-made designs have some design flaws. Often the moving parts are clogged with earth, the teeth bend, the handle breaks.
If you make such a tool with your own hands, you can avoid many problems. This will not require special material costs and will not take much time, subject to the availability of welding skills.
DIY manufacturing
Before you start manufacturing, you need to decide for yourself a few fundamental issues. The length of the bayonet depends on the depth of soil freezing. If the shovel will be used only as a ripper, then 10 cm will be enough. If it is digging, then it is necessary that the length be 5 cm longer than the depth to which the soil freezes in winter.
The width of the tool depends on the desired area of grasping the earth. But it is not recommended to make it wider than 50 cm, because in this case the applied efforts will be much higher. Industrial models are based on the design of wide forks, with a width of 35 cm, where the distance between the teeth is 5 cm.
To create a tool you will need:
Before proceeding directly to manufacturing, you need to know some design details. Most models have a horizontal frame on which the forks are attached. It is equipped with an additional emphasis in the back. Between the teeth of the main fork pass the second, supporting ones, which in their structure are more like a rake. Some instruments have two handles, but this is less common. Usually a shovel handle is used. It is best to replace the handle with a metal pipe, then the probability of breaking it will be much lower.
More simplified models have only a frame in the design, which is an emphasis. The teeth in them are attached directly to the bar, at the ends of which there are fasteners for the handles. This design is much more often made at home, but it is less effective.
The first thing to do when making a shovel yourself is to create bayonets for a working shovel. For them, fittings are used. The ends of such bayonets on one side are sharpened at an angle of 15-30 degrees. The angle depends on the hardness of the soil, for soft soil a smaller angle is sufficient.
The frame, together with the front stop, is created from square pipe. The ends of the front stop, according to the drawings, are bent at an angle of 120 degrees. All parts are cut with a grinder and welded using a welding machine. As a lever mechanism, some craftsmen use a leg mount from washing machine. It has a p-shaped appearance and is ideal for this task. The handle holder must be provided with the same fastening.
How to make a miracle shovel with your own hands, drawings and assembly procedure for an easy-to-make home tool.
The proposed design of the shovel will allow you to quickly dig household plot. At the same time, the layers of the earth do not turn over, but are very well loosened. This method of tillage makes it easy to fight weeds.
Operating principle: we press the foot on the stop, the teeth cut into the ground for their entire length; we tilt the handle of the tool towards ourselves; the teeth easily cut through the soil, forming deep furrows in it.
Better to see once
Consider what details the design consists of:
metal tooth

METAL TOOTH
Let's make from a standard metal strip with a section size of 5x50 (mm). From a piece 270 (mm) long, four teeth can be made. We mark the strip as shown in the figure. With the help of a grinder, along the marking lines, we cut off the necessary blanks. We sharpen the narrow ends of the blanks under the cone.
TEETH PROFILE
We make eight through cuts on a square metal pipe: in width - equal to the width of the tooth; in depth - to the pipe wall. The interval between cuts should be the same as shown in the figure.
UPOR
It can be done with right angles, but it is more pleasant for the “eye” if the corners are neatly bent. You can bend the corners with.

Using a welding machine, we fasten the prepared parts together.
SHAFT FOR PEN
Let's make by analogy with the emphasis
STOP FOR SHAFT
Digging up a plot of several acres is not an easy task, buying a walk-behind tractor justifies itself if there is a plot of land of at least half a hectare, and miracle shovel, do it yourself made of metal or plastic, for many it becomes the best solution.
What is this miracle shovel, the drawing of which is so popular?
It has long been known that loosening the soil has a much more favorable effect on its condition than digging it. In addition, work with a spade requires great endurance, and often time and strength. Each movement when cultivating the land is associated with a load - stick the plane of the shovel bayonet into the ground, press your foot on a special footboard, press the handle like a lever, lift a large clod of earth and throw it aside. Has nothing been forgotten from the sequence of stages of a simple technique? Even if something is missing, the essence is conveyed correctly. However, for working with hard ground, special digging forks made of hardened steel have long been used. It is this garden tool that has become part of the miracle shovel today.
Who invented this tool is not known for certain, it is believed that it was first developed in Yekaterinburg, but it is rather difficult to verify the accuracy of the information. Therefore, we simply consider the design of devices manufactured by the industry. As already mentioned, the pitchfork was taken as the basis for the idea, but not the usual two- or three-pronged ones, but much wider ones, from 35 centimeters. With a step between the working rods of about 5 centimeters, this amounts to as many as 7 teeth, the length of which is a quarter of a meter. But, of course, this is not the whole miracle shovel, the drawing is usually represented by a diagram that is more complex than just a pitchfork.
The main components of the ripper
Let's go in order. In most models, the forks are movably fixed on a horizontally oriented frame extended forward with cross stop in the back (sometimes the frame is replaced by a sled slightly curved upwards). Oppositely directed rods, somewhat shorter, are missed between the teeth, a sort of analogue of a rake. The tool may have two handles, but most often it is an ordinary handle, like a shovel or the same pitchfork. At the same time, it is far from always convenient to use a wooden handle, since such a lever can break if the teeth catch on the roots. As a handle, you can use a metal pipe, for example, made of aluminum.
If the wooden handle breaks in the socket garden tools at the base, removing the chip is quite difficult, and it is best to try to drill it out with a drill.
There are also simplified models. They consist only of a frame, which is also an emphasis along the way, since it is located behind the working part. The teeth are fixed directly to the front bar, at the ends of which there are fasteners for two handles. Exactly given type miracle shovels are most often made in home workshops on suburban areas diligent hosts. Can be used as a material ordinary pipe 20 cm in diameter, metal or plastic. The latter option is somewhat less durable, but easier to manufacture.
Finding out how the miracle shovel works, without video
Above, we described the process of working with a conventional spade, now it's time to shed light on how exactly the ripper in question should be controlled. So, the standard factory version with a frame is installed on the ground at the edge of the area to be processed. Slightly raise the tool by the handle and direct the forks into the ground. Next, press the foot on the frame (an action that does not require special efforts). The teeth easily penetrate the soil to the full length, now it only remains to press the handles so that the rods of the working part cut the soil, loosening it and lifting individual layers. This is where counter teeth are needed. The purpose of this part is to break up the clods of earth lifted by the pitchfork.
Understand how the miracle shovel works own production, you can do it without a video, because everything is simpler here. Firstly, due to the closer arrangement of the teeth on the frame, the working part does not lift large lumps of soil, breaking them in the process of movement. Secondly, in factory models, the hinge of the moving part is sometimes clogged with earth, which makes it worse to turn, and wooden handles inserted into special sockets often break. In a home-made device, the parts are rigidly connected, and therefore breakdowns and jamming are excluded. There is a possibility of deformation of welding or soldering seams, as well as breakage of plastic parts, if any, but this can only happen after a solid tool life.
Instructions on how to make a miracle shovel with your own hands
At home, it is better to make a simplified model that differs from the factory one in the complete absence of moving parts. If you have a welding machine, it is best, of course, to make metal inventory, otherwise optimal solution there will be a design of plastic pipes. It is undesirable to assemble a ripper on bolts, since such connections will loosen during operation, and the nuts will have to be tightened all the time. Regardless of whether the fixture will be made of plastic pipes or metal pipes, you still have to weld them, so we’ll just step by step consider the process of how to make a miracle shovel with your own hands, without focusing on the tools.
How to make a miracle shovel with your own hands - a step by step diagram
Step 1: Preparing the Parts
We will need two pieces of a metal pipe of 60 centimeters and the same number of 25. We will also need a pair of corners (namely triangular plates) and 6, 7 or 8 teeth from the pitchfork, or just high-carbon steel rods. If you intend to make a plastic frame, then in addition to pipes, you need 2 corners and 8 or 9 tees, depending on whether the ripper is six or seven teeth. Also, for the PVC variation, adapters may be needed to connect to metal pipes. In any case, it is advisable to make the handles of steel, adjusting them according to your height.
Step 2: Frame Assembly
From metal to assemble the desired workpiece future design not difficult, it is enough to make 4 seams welding machine. Another thing is if you do not know how to work with this unit and have never picked up a holder with an electrode. Then the most affordable option- PVC, fortunately, the blanks listed above are not difficult to get. First, using 4 corners of pipe sections of the above length and two tees, we assemble the back of the frame. To do this, we weld equally oriented corners on the sides to a sixty-centimeter piece of a round profile, from which the sidewalls will stretch 25 centimeters each. Next, we fix the tees on them with the forks up, and then with the help of short segments 2 more corners, with which we close the frame contour. Now the front part. We also weld tees to the last corners with small pieces of the pipe and so on until we connect them all. The side outlets of the tees should look down.
Step 3: Fixing the teeth
We weld the rods onto the metal frame so that they bend forward, so it will be easier to move the working part in the ground. We position it on plastic in exactly the same way, however, if the teeth are thinner than 13 millimeters at the base, they will not only have to be melted, but also filled in the void in the tees epoxy glue or automotive putty based on it. But it is best, of course, to weld thin rods onto thicker bases and fuse them into PVC.
Step 4: Attaching the Handlebars
TO metal frame we weld the handles in the front part at the corners, additionally fixing them with triangular plates (as a result, we get 3 joints, two end and one circular seam). TO plastic construction it is also better to fasten steel handles, but only after cutting threads at their lower ends. To the tees, the side outlets of which look up, with the help of short segments we weld adapters from plastic to metal, and screw a pipe with a diameter of 20 centimeters into them. The Miracle Shovel is ready to go.
If you have a small land plot, then you know firsthand what it is to dig the earth by hand. The pleasure is still that ... The process is not easy and not convenient, it requires a lot of effort and time, and health for this business is far from weak. Such work is definitely not up to a woman, a teenager, an elderly person, or people with a disease of the back and spine. But, as you know, gardeners cannot do without this procedure, whether you like it or not, but twice a year, you are welcome to put a shovel in your hands ... And then, twice a year it is only obligatory digging, loosening the soil, and if it is also planting tuber crops, and also the harvesting of this crop ... In short, if you have already taken a shovel in your hands in the spring, then you will part with it only in late autumn. Given that this type of land work, well, how not to be canceled, something happened that should have happened, they began to improve the usual shovel.
Possibilities of the miracle shovel "Kopalochka"
We present to your judgment a couple of opportunities to facilitate your work in the processing of the land.
First, we suggest you try the method to improve the shovel with your own hands. Add to your shovel, so to speak, a foot pedal, consisting of a clamp that secures the pedal over the working blade of the shovel, a hinge and the pedal itself, and a handle on top of the handle, for convenience. Now, from your shovel, or pitchfork, if you wish, you can use these devices for one and the other, you get such a miracle shovel "Digger", a shovel that digs itself, capable of facilitating the difficult process of digging the soil. Using it is very simple: you put the tool in the ground. press the pedal, during which the bayonet-blade easily cuts into the soil, and by pulling the handle to the bottom, easily loosen the layer of earth. At the same time, there is no need to bend over and squat as when working with a conventional shovel, which means that the load on the back is completely removed, and the load on the legs is eased several times. It is easier, more comfortable, and faster to work, moreover, no back pain. Such a miracle digger is ideal for planting potatoes, and when harvesting a tuber crop.
Secondly, you can this new gardening equipment, which is called a super shovel, buy ready-made, factory assembled. The principle of operation of this equipment is the same: the pedal fixed above the working blade provides work mainly with the legs without the need to bend down and squat. But the working blade itself is wider and more convenient, its width is fifty centimeters, which determines the grip greater territory processing and as a result, the work is done much faster. True, this miracle inventory cannot be used for digging up tuberous crops precisely because of the width of the blade, since the coverage of the cultivated area is quite wide, far from the size of a potato bush. The handle is made on the principle of a bicycle handlebar and provides the easiest control of the working blade. And yet, the handle of this shovel is equipped with a handle height regulator, which provides easy regulation for the height of the worker.
Modifications and tool weight
When buying, you can choose a shovel with a suitable working width:
- width of the working blade is fifty centimeters (small width), recommended for work by the elderly, women or teenagers,
- the width of the working blade is seventy centimeters (medium width), recommended for work by middle-aged people and men,
- width of the working blade ninety centimeters (maximum width), recommended for men with good physical data,
Please note that the weight of the product will directly depend on the width of the working blade:
- fifty centimeters (small width) - weight 5.3 kilograms,
- seventy centimeters (average width) - weight 8.5 kilograms,
- ninety centimeters (maximum width) - weight 9.5 kilograms,
The depth of loosening with any of these sizes will be the same, twenty-seven centimeters.
Actually, twenty-seven centimeters is optimum depth, on which it is worth digging, loosening the soil. At this depth, mixing and saturation of the fertile layer of the earth with oxygen occurs. Which in turn will provide good harvest on your land.
So, we introduced you to a new invention in the gardening equipment industry. A super-shovel, which is worth buying for every gardener or gardener, for every owner of even a small plot of land. After all, this is not just a shovel, it is truly a shovel that digs itself. It has a lot of tangible advantages over a conventional shovel. Only with it you can easily process your land, saving time and effort.
Advantages of the super-shovel "Kopalochka"
This tool will allow you to:
- increase the productivity of their labor by digging the land several times,
- perform a large amount of work in a minimum period of time,
- work with this miracle inventory saving time and effort,
- work with this tool without strain on your back, as you do not have to bend down,
- choose the option of the width of the working blade 50, 70, or 90 centimeters,
- adjust the length of the handle to fit your height, which will make it even easier to work with it.

You don't like digging your front garden? You've just never held a really cool gardening tool in your hands! How to get the most out of your gardening with the least amount of physical strength? Drawing miracle shovel and detailed instructions on its manufacture from improvised materials will help you with this!
We prepare materials for the manufacture of a miracle shovel
A branded tool, which you can buy at a hardware store, consists of a frame, an anti-cutting element, a working base of 8-9 rods resembling a pitchfork, 2 support posts and a handle holder. We will now make a similar design with my own hands. And with the money saved, we will be able to buy seeds for sowing throughout the garden, including neighboring plots, since this device costs a lot of money in the store.
Let's start with the frame. It can be welded using a welding inverter from a metal square with a cross section of 25x25 mm. To do this, you need to do only 4 welding seams and 3 cuts with a grinder. We measure 60 centimeters and cut off 4 pieces of a square profile. Then we cut off another 1 with a section of 20x20 mm - we will have it in the role of the middle jumper in the frame, on which the counter-cutting elements will be attached. If you don’t want to spend a lot of time making such a ridiculous design, you can simply take a frame from a baby stroller or disassemble an unnecessary sled. Their dimensions will be a little larger - that's okay, they can be compensated for by the number of teeth on the working surface and reduce the force on the handle.
Now we proceed to the choice of the forks themselves, with which you will loosen the ground. They must be strong, like a communist idea, otherwise they will bend with the slightest effort. The steel must be hardened, the bayonets are straight, it is undesirable to make bends. For such a role, a fishing prison, which every self-respecting poacher has, is ideal. Here you can help nature by exchanging fishing tackle for something useful in the household, and yourself, since the best tool we can't find. You can also make it to order from a turner, but it will cost much more. The most extreme case is to install conventional pitchforks. But the result will suffer significantly, because the steel is very soft.
The choice of counter-cutting tool should also be taken seriously. Ordinary steel can also be used here, since the role of this node is to break up lumps that will be picked out by the “active” part of the tool. Width - about 50 centimeters, tooth frequency - after 5-6 cm. Perfect option- a scraper for cleaning beds from stainless steel, which was previously used. It can be found in almost every retiree who likes to keep artifacts in his barn. Offer to exchange with you for new, beautiful, modern and "quality" pitchforks domestic production– most immediately agree. And you feel good, and people have helped. Then we break off the holder from them together with the handle, if it doesn’t work out, we saw off with a grinder. We pick up the “cassette” with teeth on a shovel-ripper.
It is even easier to find a handle holder - we break any unnecessary tool or look for a pipe with a diameter of 30-40 mm and a length of 15 centimeters. Now it remains to make the lever mechanism. For it, you need a wheel from an old Soviet car (fortunately, there are a lot of them in scrap metal and in villages), we beat off the plastic, and there remains a U-shaped mount. We need 2 such mounts.
Step by step assembly instructions
Making a miracle shovel is a very interesting and responsible business, since the effort that will need to be exerted when working with the tool will depend on the quality of your assembly. Follow the instructions so that your creation will please you for more than one year.
Step 1 We make a frame.
First of all, we collect it in a heap. If we have a square profile, then we can do without reinforcements, just weld it. If you have adopted a stroller, then you will need to make oblique spacers in the corners from a metal strip or a square profiled pipe. It will be enough to install 8-10 cm inserts so that they distribute the pressure exerted on the frame when digging.
Step 2 We make a lever mechanism.
Here we need a U-shaped mount from the wheels washing machine. We weld it upside down to the frame, drill an 8 mm hole in the sidewalls exactly in the center, maybe 10 mm, so that our super shovel is strong. We weld exactly the same fastening to the handle holder, again drill holes 10 mm opposite. Now we bring 2 fasteners so that 4 holes are in one row, we hammer the axis 10 mm inward. We get a lever mechanism with a force of about ½. This will be quite enough to work in the front garden and in the garden, even with dense dry soil. You can additionally strengthen the sidewalls with a metal plate, but this is superfluous - in most cases, such an attachment is more than enough.
Step 3 We weld counter-cutting.
The scheme of the miracle shovel involves the use of oblique shear blades directed at an angle of 45 0 to the ground. This scheme allows you to significantly reduce the effort when breaking clods of earth. You can install them horizontally, but with very dense soil, they can bend up, so experiment for the sake of a beautiful appearance tool is not worth it.
Step 4 We weld the back support.
The relevance of its presence on the tool in general should be called into question, since its main role is to equalize the depth of loosening, which can be done easily “by eye”. But, since we need a high-quality miracle shovel with our own hands, we will not change the drawings here. We weld the T-shaped mount in the middle of the frame at the back - the limiter is ready.
Step 5 We make a cutting.
Strongly bother your head is not worth it over this operation. We buy the simplest pine stalk and hope that he will not die long. Broke - buy a new one and work again. You can try to buy an oak stalk or larch without knots, but its price is 10 times more expensive, but the strength - how lucky.
Now we have almost made a shovel for the lazy with our own hands. It remains only to paint it in a neat color, so that only original details distinguish it from the new instrument.
Alternative drawings or "what can be replaced"
Above, we described the drawing of the ripper, but there are still very practical models of shovels that can significantly simplify work in the garden. Such a tool will be especially relevant when harvesting, where it is necessary to turn the soil over, and not to loosen it.
If you need just such a miracle shovel, its drawings and dimensions will differ significantly. Firstly, the work area will be a metal plane, not pointed segments for loosening. The countersinks are removed. All that remains is the mechanism itself to reduce the effort to turn over the earth clod. That is, its advantage will be only in the absence of back tension - the earth is lifted by pulling on the shovel handle.
The lever must be made at a height of 45-50 centimeters from the ground - this is the optimal ratio of the height of the lift and the effort expended on it. Some models are made with a very high lever, then the effort will be needed more to lift, but the scoop itself rises to a great height - it is very convenient during construction (digging trenches).
Another very popular design of the miracle shovel is a tool with a triangular support. Its essence is to significantly reduce the effort precisely when digging an earthen coma. Its subsequent transportation is carried out using the spinal muscles, which will not satisfy the requirements of many builders. This design is perfect for working in too hard soil, where it is necessary to exert a lot of pressure precisely in the process of undermining the coma.
