Do-it-yourself haymower: drawing, materials, manufacturing instructions

How to decide on design features

A homemade mower can be rotary or segmental. The first type is the most popular and convenient in terms of performance characteristics. The working part of the equipment is a disk with floating rotating knives. Such installations are effective when you have to mow tall grass.

Movable knives cope with weeds. If you want to make a device from a chainsaw, then there is no doubt, because the unit is excellent for conversion, and in addition, you can transform it back. A gasoline mower will have blades made from wood saw blades. You can also use sharpened metal teeth.

Safety precautions

During assembly and installation, all welds and connections should be checked. If this point is not followed, the device may break during operation, jam adjacent parts and cause damage to the operator or a person nearby. When starting up and operating the equipment, you must make sure that there are no people, animals, metal objects, or solid materials nearby.

Making a rotary mower is much simpler and lighter than a segment mower. But if you have the materials and the desire, then you can cope with this task. The hay-chopper will be able to perform various agricultural work.

The most common mounting system for a mower on a mini tractor is a mounted one. And the drive system is chain. The flail mower is very convenient and reliable.

A homemade tractor-mounted mower is an important tool for farmland. These homemade products are stronger, more reliable than factory ones, and will last much longer. Homemade mowers for mini tractors are more functional and easier to assemble.

Features of manufacturing a segmented mower

If we compare segmental devices with rotary ones, then the attachment in these units will be carried out to a walk-behind tractor or mini-tractor. The main difference is the operating principle of the knives. The working part of the equipment consists of long and narrow blades that have teeth; they operate on the principle of reciprocal motion. You can start working by driving the equipment using a drive belt. You can also use the power take-off shaft for this.

These design features depend on the walk-behind tractor model or the mechanical tool you plan to use. Once you have completed the segment mower, you can use it when mowing lawn grass. Portable modifications provide the ability to process bushes. The gear wheel is rigidly coupled to the engine.

How to make a mechanical mower with your own hands

You can make an inexpensive manually operated mechanical lawn mower that is useful for the household. Two types of knives should be made: the first ones rotate and collect grass, the second ones are stationary and cut plants. Using transmission from gears and wheels, it is necessary to create the required rotation speed of the knives. The grass needs to be cut using the scissors method. Then you need to fulfill the conditions for the operation of the knives, between which there is grass. The elements should be given a curved shape for continuous cutting of grass.

Using a chainsaw

A gasoline mower will be an excellent help on the farm. But first you need to prepare tools and spare parts. The domestic models “Druzhba” and “Ural” are suitable for solving the problem. Additionally you will have to purchase:

metal corner;
2 wheels;
pipe cutting;
metal knives;
metal plate;
rotor discs;
bearing;
accessories.

As for the corner, it will be used to make a rigid frame. But a metal plate will be needed for the platform. You don’t have to buy wheels, but borrow them from a stroller or cart. The pipe cut should have a diameter within 5 cm. To mate with the pipe, you will need a gear. A homemade haymower will be made using accessories, namely:

nuts;
bolts;
rivets;
staples

Precautionary measures

When using this equipment at home, you should follow safety precautions. There are only two main dangers:

Injury from knives.
Electric shock.

For this reason, you can inspect the mower only when it is turned off, and before using the device, make sure that all points where electrical wires are connected are well insulated. Moreover, it is worth collecting all the debris on a flat area where you plan to work, so that it does not cause damage to the device and does not cause injury to a person. The production is described in the video tutorial.

Assembly Guide

If you want to make a mower using a chainsaw, you will need to insert a pipe into the bearing groove. There should be a gear located inside. Ears are welded to one end of the pipe, each of which is 2 cm long. Holes are drilled in them. You can make knives from a saw blade.

The lath is cut into the required number of equal strips. Rivets and bolts will allow you to fix the knives on the rotor disc. A metal strip can also serve as a base. When choosing the diameter of the rotor, you may prefer the traditional value, which is 39 cm. A drawing of such a device will be the best assistant for anyone who decides to make a mower with their own hands. It needs to be studied first.

From a metal corner you can make a rigid frame, the parameters of which will be equal to the dimensions of a gasoline tool. There will be a rectangular stand inside the structure, on which the body rests. The connections must be made at right angles, and they must be made as rigid as possible.

Work methodology

Mounts for the handle and wheels should be welded to the frame. Hooks made of a metal rod will act as a support. At the next stage, you can begin installing the wheels. The chainsaw must be prepared; for this, the blades and chain are removed from it, and then attached to the frame.

The design of the mower will include a protective platform in the form of a plate, which is prepared taking into account the contour of the body. A pipe is attached to the tool sprocket, which will contain the working part of the equipment. Now you can begin to fix the lever, handle and cable system, the last of which will be responsible for turning the equipment on and off.

Using a grinder

If you don’t have a rotary mower, but have an angle grinder, then you can make the equipment from a grinder. The mower is a seasonal tool, so it would be more rational to prepare it for a certain time of year. For example, you can also convert a grinder into a milling machine, as well as a drilling machine, a chain saw and a lawn mower.

In order to make a haymower from a grinder, you will have to cut a passenger car wheel disk into two parts. Only one part will be used in the work. On one side it should be covered with a sheet of metal. In this case, a metal blade from a circular saw that has served its purpose may come in handy. This will allow you to obtain the equipment housing. The handle and wheels are attached to it using electric welding. An angle grinder is installed on top.

The enclosing casing on the unit must be secured as tightly as possible. At the next stage, the required holes are drilled in the frame and casing. Fastening is carried out using bolts. This will allow you to secure the angle grinder to the mower. When assembling the mower with your own hands, you must remember that the working shaft of the main tool is not very long, so attaching the knife to it will be problematic.

To solve the problem, you need to screw a nut with an extended thread onto the shaft, only then can you start attaching the blades for the mower. With the help of the resulting tool you can fight short grass. A cavity can be created in the nose of the equipment, which will be intended for cutting grass. The nose part will not be pressed to the ground by the half-disc. To do this, part of the mower moves forward so that the grass is not laid on the ground before cutting, but has time to rise.

Construction of mower cart

This mower resembles a rotary mower, but is more complex in design. Its main advantage can be considered a large mowing force, which allows you to remove plants with a rigid tree-like stem, and in winter, through small design changes, use it as a snow blower. The basis of such a mower is a welded frame made of iron corners, mounted on 4 wheels, perhaps from a baby stroller. A floor made of sheet metal or at least thick plywood is placed on the frame. The frame parameters may vary, but a rectangle of 80 by 40 cm is considered optimal.

2 rotating drums are installed on the frame, which can be used as large-capacity cans. The lid and bottom of such a jar are cut out and replaced with wooden circles. Cans can be replaced with disks made of sheet metal. They need to be made in the amount of 8 pieces, 4 of which should be external and have a diameter of 20 cm, and 4 - internal, with a diameter of 17 cm.

They should be connected in pairs, the larger one with the smaller one, using bolts, and 4 knives should be attached to each disk at an equal distance from each other. They must rotate freely, for which a gap of about 1 mm must be left between the blade and the surface of the disk. All that remains is to insert the bushing into the drum and secure it to the frame.

On the frame you need to install a cross member from an iron angle 35 by 35 mm. The side parts of this corner need to be cut off by the same 35 mm so that M5 bolts can be screwed in. The drums are connected by a transport belt, for which the corners must be equipped with grooves 13 mm wide. The lower drum bushing is movably attached, and special tension corner parts are attached to the upper ends of the drums. They are tightened to the ends of the transverse angle using M5 screws 6.5 cm long. The design as a whole is quite understandable. The conveyor belt can be made of a strip of thick rubber, which is connected into a ring with a 2 mm thick aluminum plate.

Making a manual segment mower

If you plan to make a manual mower in the form of a segment device, then you should use metal bars with dimensions of 15x50x120 mm. Holes are drilled in each of them to install bolts. A guide rail is attached to the latter; its length should be 90 cm. The knives on it are located on both sides of the beam. The ends of the latter are fixed with runners and clamps.

At the bottom of the frame you need to fix a wheel, which you can borrow from a stroller or children's bicycle. The cutting part of a manual mower will operate under the influence of a walk-behind tractor. However, even if you assemble the unit correctly, then in any case you must follow the recommendations for installing the equipment.

The walk-behind tractor must be set to reverse mode. The coupling socket houses the connecting unit. Using a kingpin with a spring, you must secure the connection, otherwise the towing mechanism will not work. The mower blades should be protected with a guard during installation. The weights located on the wheels should be removed, because they will not be needed for mowing the grass. Work must begin by engaging the clutch, setting it to minimum speed.

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.

Features of manufacturing a rotary mower

The rotary device is used for harvesting grass and mowing lawns. The equipment will be able to chop small vegetation, and mow tall vegetation to the roots. Homemade mowers of this type are attached to a walk-behind tractor; due to their small size, they are simply not suitable for a tractor.

If you decide to make your own mower, you can use the Neva walk-behind tractor or a similar model of such equipment as a base. To carry out the work, you should prepare two disks borrowed from a grain seeder. You will need a chain and gearbox from the saw. For each disk it is necessary to prepare four metal knives made of hardened alloy. To install them, 6 mm holes are drilled in each disk. The tire will allow you to fix the knives on the disks so that there is a gap between them that exceeds the thickness of each of the knives by 2 mm.

Types of mowers for walk-behind tractors

You can find a mower for a walk-behind tractor in stores or make it yourself. Don’t rush and start making equipment yourself. First, you need to compare the prices of haymowers in stores; they are not as small as we would like, but not exorbitant.

Craftsmen who decide to make their own mower are attracted by the fact that they can save money on equipment.

In addition, the process is not very complicated; there are quite a few different drawings of ready-made models of mowers on the Internet, and something created with your own hands helps you experience delight and pride.

The type of mower you choose depends on the type of area. The earth differs in relief, the grass in volume, size, composition. It is based on these parameters that you need to choose a technique. There are only three types of walk-behind mowers:

Rotary

The model is suitable for areas with low vegetation and small bushes and grain crops. The mower is quite productive, it is used on a relatively flat area with slight slopes (10-20 degrees).

The lateral slope on these models does not exceed 8 degrees. A significant disadvantage of using a walk-behind mower is a high chance of injury. After mowing, the grass is folded in rows, which allows you not to bother with it in the future. Rotary models have a very simple design, which reduces the risk of breakdown.

In a separate article you can read about attachments for the Neva walk-behind tractor.

Segmental

The knives of this model move in a forward-reverse direction due to the operation of the shaft of the motor system. The design features of a segmented mower for a walk-behind tractor are more complex than those of its analogues, which contributes to the complexity of maintenance. But the models have a number of advantages: the lateral equipment of the equipment eliminates the possibility of working with already mown grass, unlike rotary options. When mowing, moving cutting parts move along the topography of the ground, repeating the landscape. This mechanism allows you to cut plants almost to the very root.

The mower operates with a blade deflection of 20 degrees, this allows you to process even the most uneven areas of the ground. The mechanism for activating and disabling the equipment is not at all connected with the walk-behind tractor drive. This solution allows you to easily turn off the mower in dangerous situations.

The balance of knives in segment versions is adjusted to the maximum, which allows reducing vibrations in the structure to a minimum.

Cart mower (drum)

The design is similar to the rotary model, but the mechanism is a little more complicated. The mower is made of drums, which are fastened with a frame and fastenings with a tape.

Cost of spare parts

Before you start manufacturing the equipment described in the article, you need to ask what the cost of spare parts is, because you will have to purchase some of them. For example, a carrier sleeve that fits a Virax mower will cost the consumer 50 rubles. But you can buy a drum casing for 1200 rubles.

The rear hinge bushing costs a penny - 40 rubles. a piece. This is the price for distance protection. When considering spare parts for a mower, you should also pay attention to the drive shaft. Its cost is 500 rubles. A knife holder will cost you 250 rubles. The drum bushing costs 2,400 rubles. A belt pulley equipped with a latch will cost 4,000 rubles.

The T-25 doesn't have enough strength

Only those who do nothing make no mistakes

For the T25 there is a Polish rotary drum mower, I saw on the Internet they make these and homemade ones.

something like this is needed

Wow

I wanted to do something like this

t 25 will not pull 90 percent of its MTZ with a load and a good weight. and in the swamp the belts are already slipping. for T-40 and T-25, buy polka 169 and sell this one.

I wanted to do something like this

Somehow I got rid of this one and bought a Polish KDT-260

Only those who do nothing make no mistakes

What did you use to carry the trailed mower? and how much did you buy a new one?

I carried the trailed one on the MTZ-80, I will carry the new one on the MTZ 892.2 for 1,600,000 tenge.

Only those who do nothing make no mistakes

318,000 rubles is a significant amount

At the moment I am sorting out the blade for a trailed homemade mower. ran into trouble, the previous owner screwed everything up

will it work like this?
