Today, the variety of equipment that relates to the agricultural sector never ceases to amaze each of us. Undoubtedly, the main activity of each of them is to facilitate human labor in relation to agricultural work. After all, we all know how difficult it was for our ancestors, who, in order to simply feed themselves and their families, spent whole days in the fields in order to bring their land into proper shape and therefore reap a good harvest, and a lot of effort was spent on this, because they worked with using homemade hand tools.
Fortunately, it is much easier for us now, because technology is developing every day and has risen to quite great heights. All that is required of us is to sit comfortably behind the wheel and simply control the vehicle that will do all the work for the person. Undoubtedly, there are a great many units that are ready to help us in this difficult task, and it’s up to you to decide which lawn mower to choose.
Consequently, it can be said without a bit of exaggeration that the progress of the technical direction fully complies with all the requirements regarding tools of labor.
Actually, we will talk about one of them in this article, namely the rotary mower, which today is very popular among landowners. You will be able to learn about the principle of its operation and aspects of its design.
Moreover, given that this kind of tool is quite, let’s say, not cheap, we will tell you how you can make this unit with your own hands. So, let's actually start looking at this topic.
Main types of mowers
All mower models are divided into two main blocks. They can be either rotary or segmental. This can also be seen by studying photos of homemade mowers.
A mower that is considered a segment mower is quite capricious to maintain due to the fact that it is prone to frequent blockages.
Therefore, work has to be stopped and the equipment cleaned. This is why homemade segment mowers are made less frequently by gardeners than rotary mowers.
Where to look for drawings, ideas and technical solutions?
The main sources of ideas, schemes and technical solutions are thematic forums where users discuss their homemade products and share with each other drawings for making rotary and other mowers with their own hands.

Description of mowers
The main function of this type of agricultural machinery is already contained in their name. They are designed to cut grass.
The rotary mower has long received another name, which can be heard no less often than the main one. It is also called disk. Since special discs are responsible for the main function of cutting grass.
As a rule, a disc mower is a homemade mower for a mini tractor and it only works in conjunction with it. Its essence is quite simple, namely, the wheel is driven, which is considered the support of the entire structure. Then, thanks to the wheels, the cutting system begins to function.
Installation methods
All rotary mowers are installed in one or more of the following ways :
- front hitch;
- side hinge;
- rear hitch;
- fastening via a manipulator;
- transportation using a towbar.
The front linkage is used only for cutting grass in the fields, because such an installation greatly limits the maneuverability of the tractor.
Side and rear linkages are the most popular, because they not only provide the operator with good control over the cutting tool , but also allow the mower to be moved to the transport (vertical) position without compromising the forward visibility and maneuverability of the tractor.
The manipulator is placed at the back or side, not through a standard suspension system, but by attaching it directly to the body. This is due not only to the large mass of the equipment, but also to its dimensions - being installed at the front, the manipulator will greatly impair visibility from the tractor cab.
The connection of semi-trailer and trailed devices is made using various trailer hitches, some of which must not only drag the mower, but also change its position relative to the tractor, moving it sideways.
Regardless of the installation method, the energy for operating the mower’s cutting tool is obtained from the power take-off shaft, and the transfer from transport to working position is carried out by hydraulic cylinders operating from the tractor’s hydraulic system.
Composition of the mower
Without exception, all drawings of homemade mowers will explain in detail the number of components for their creation. Therefore, you should not neglect the analysis of circuits, but it is more optimal to build yours based on the parts in stock.
But there are still components that are required for any model:
- Wheels, which are taken in diameters up to 45 cm and in quantities of 4 pieces, respectively.
- The axis responsible for all the fasteners should be 2 pieces in the design.
- Metal sheet, size varies depending on model.
- Knives, for the design you will need 4 pieces.
- Also, to fasten the parts you will need screws, which should be in abundance, and nuts.
- A special metal barrel with a bottom.
- Welding machine.
- Handle for control. It can be replaced by a less convenient component, namely a pipe.
It is worth noting that not all parts need to be immediately purchased. In this case, the instructions themselves on how to make a homemade mower will turn out to be quite expensive.
For example, wheels left over from an old stroller can also be used as wheels for equipment, if they are metal.
There will also probably be a suitable barrel on the site. Therefore, when drawing up a diagram of a future device, it is worth first assessing what can be used from what is available.
From the washing machine
The design of an electric lawn mower, which is based on a washing machine with a working motor, is simple. Assembly algorithm:
- take a motor from an unnecessary electric washing machine with a start relay, equipped with a capacitor;
- prepare a sheet of steel with dimensions of 30 * 50 cm, cutting a hole in its center to remove the rotating part of the engine;
- attach the motor to the middle of the steel frame so that its moving part protrudes slightly from below;

- make a knife from a steel strip and sharpen it by making a hole in the center;
- grind a flange to connect the knife to the motor;
- put the cutting knife using a flange onto the engine shaft from below and secure it with three bolts on the shaft, as well as one fastener from below (it is necessary to ensure that the cutting ends do not extend beyond the steel sheet when torsioned);
- install one wheel from an old stroller for children from the four corners of the base sheet (the distance from the knives to the ground should be about 5-6 cm);
- attach the handle to the sheet on one side and bring out the electrical wire to the handle, wrapping it in several places with electrical tape.
Basics for Building a Mower
There is no need to rush to throw away equipment that is no longer intended to be planned at home, since it can be used for another area of work.
Thus, mowers are created from old vacuum cleaners, supplemented with special knives, as well as even from bulky and clumsy washing machines.
The main thing is to understand the essence of the action of this technique for mowing grass, and there are many ideas from which it can be made. If you improve the grinder, then it can also be turned into a device for mowing grass.
How to make a mower for a walk-behind tractor with your own hands - manufacturing options
Almost each of the listed types of mowers for the walk-behind tractor available on the farm is quite easy to make yourself. The only problem is that problems may arise when assembling the frontal equipment, since it is quite bulky and requires the purchase of many hinge mechanisms.
The most popular among farming enthusiasts are rotary and segmented attachments for walk-behind tractors. They have a simple design, and their manufacture does not require specialized equipment.
Characteristics of rotary mowers
- This technique can be adjusted to the required height. That is, its use is practical and convenient both for small young grass and for entire thickets.
- Its speed can be either maximum or medium, which is convenient for working in hard-to-reach places.
- Due to uninterrupted operation, the mower has high productivity.
If used correctly, this equipment will become a faithful assistant for many years to come.
Design
Regardless of the type of these devices, the general layout is the same and consists of :
- frame;
- drive;
- cutting tool.
The frame connects the cutting tool to the tractor through a standard or non-standard suspension and also ensures proper operation of the drive. In turn, the drive ensures the transmission of rotational energy from the power take-off shaft (PTO) of the tractor to the cutting tool, which does the main job, that is, mows the grass.
When manufactured independently, the design of each of these elements depends on the available materials and skills .
Operating mowers
Equipment must be constantly lubricated. The frequency of this process depends directly on the frequency of use. The knives that are responsible for mowing the grass need to be changed periodically.
It is not difficult to understand that replacement is required. Firstly, the equipment will begin to work worse, and, secondly, when it is turned off, you can swipe
It is important to check the area before starting work. Because if, for example, a collision with a stone occurs, the mower can be severely damaged.
The minimum consequence for such an incident would be to replace the disk. The most common injuries that occur when using mowers are those that occur while the mower is on. Therefore, under no circumstances should you begin to inspect the equipment without first turning it off.
From a chainsaw
Homemade electric lawn mowers can even be constructed from a chainsaw. To do this you will need:
- engine from the Druzhba chainsaw;
- frame made of durable metal;
- protective (protective) casing;
- knives;
- wheels;
- pens.

First you need to make a kind of cart by welding a handle to control the mower and wheels to the finished frame. Without changing anything in the motor mechanism, you need to install it on a cart (homemade chassis), after first removing the “steering wheel” from it and screwing it to the handle of the mower. You will also need to increase the length of the fuel hose and gas cable. To place the shaft at the bottom, you need to screw it onto the frame using the hole on the gearbox. Additionally, it is necessary to use the flywheel housing studs for fastening. After strengthening the blades onto the shaft, you can begin working with a homemade tool.
Correct connection of the mower
- It is necessary to inspect again and check for connection all the fasteners that were previously installed.
- Pay special attention to the walk-behind tractor or the device that will be used on it as a moving force.
- The mower starts, as a rule, only at low speeds: a high speed is not initially selected.
- Check how the grass is cut in a small visible area.
- If during operation any noise seems to reappear, then this is the first sign that there is a malfunction, so it is recommended to immediately stop work.
If you follow all the recommendations, you can create equipment that, neither in its service life nor in the quality of the work required of it, will be inferior to any purchased model.
Installing the mower on a walk-behind tractor
Properly manufacturing a mower for a walk-behind tractor is not all; it needs to be connected to the walk-behind tractor. Assembly Guide:
- Activate reverse.
- Any installation manipulations to the PTO are performed by moving the unit into the mounting socket.
- Secure the connection using a pin with a spring. Missing spring may cause damage.
- Cover the knives while working.
- Remove weights from the wheels of the walk-behind tractor (needed for working with soil).
- Mowing occurs at low speeds.
- Maneuvers should be smooth.
Regardless of the type of walk-behind mower you make yourself, you need to ensure that everything is securely fastened and installed. Safety is very important.
