Homemade mower. Homemade rotary mower

On the domestic market of agricultural machinery is presented a whole mass of effective solutions for working on household plots and caring for lawns. The highest demand today is for rotary mowers. Such devices are characterized by high productivity, easy operation, the possibility of installation on a tractor and a motor-block. In view of the special simplicity of the structure, if desired, a self-made rotary mower can also be manufactured .

Let's look at the design features, the principle of functioning and the ways of self-assembling the devices for cutting the grass, harvesting the weeds and caring for the lawns.

Principle of operation

The operation of the rotary mower is based on the reproduction of rotational movements on the working shaft. To the latter are attached knives, the block of which resembles the shape of a rectangular bar. Thanks to this structure, sequential gripping and careful cutting of plants are ensured.

The wide distribution of rotary mowers has acquired in view of its economy. To bring the rotating blades into motion, energy is used here, which is supplied directly from the traction machinery. Therefore, to ensure their operation, no additional fuel consumption or creation of a separate connection to a centralized power network is required.

Types

There are several types of rotary mowers:

• Trailed;
• Hinged;
• Semi-mounted.

Both the factory and homemade trailed type mower is attached to the transport using a three-point attachment. This makes it possible to change the angle of inclination of the cutting mechanism relative to the surface to be machined.

Hinged homemade mower for motoblock is statically fixed on the mini-tractor with the help of standard fasteners. Due to its compactness, it is ideal for the processing of relatively modest land areas.

As for semi-mounted attachments, the latter do not have very wide possibilities for adjusting the position of the knives. At the same time, these devices are designed to mow grass in areas of considerable area.

Features of operation

The self-made rotary mower can be effectively used by the owners for the bevel of high grass, which is planned to be laid for drying in rollers. Some devices of this category are able not only to form even rows of sloping plants, but also suitable for their thorough grinding.

Self-made rotary mower

For the hand-made manufacture of a rotary mower, it is necessary to prepare knives, which will be sequentially placed on disk circles. As a means to ensure rotation, it is necessary to use a power shaft. The basis for creating a framework for future adaptation will be iron corners. The use of old scrap is allowed.

Course of work

The homemade mower is manufactured as follows:

1. For the construction of the rotor, a metal sheet is prepared, from which two disks with a diameter of about 40 cm are cut out. To save on the purchase of material will allow the use of an alternative variant in the form of a bottom from an old bucket or a barrel.
2. Axial shaft will serve as any metal pipe section of about three centimeters.
3. To ensure the rotation of the structure, it is necessary to fit the shaft to the bearings. In the subsequent on it put on disks to which the cutting knives are in advance welded.
4. Then, using the same welding machine, the mechanism is attached to the metal frame.
5. The mower is equipped with a protective casing, which will ensure safety when performing work.
6. Finally, the shaft of the construction is equipped with wheels.

Such an adaptation will allow cutting the plants at a speed of about 10-12 km / h. With the acceleration of movement, the grass will be more crushed, in the case of unhurried work - holistic. The device is ideal for cleaning the garden or garden area from weeds.

Homemade mower for minitractor

It's one thing to assemble a practical rotary mower with your own hand, quite another - to correctly attach it to the tractor. During the installation, you should pay attention to the following:

1. Tractor or motoblock must be switched to work in the "Reverse" mode.
2. The rotational shaft of the technique is coupled by a pass connection to the shaft of the mower.
3. During installation, the knives should be closed with a protective cover.
4. On the wheels of most models of motor blocks, there are loads that contribute to a more thorough cultivation of the soil. When the equipment is equipped with a rotary mower, the latter are useless. Therefore, they need to be removed.

At first, a self-made mower for a tractor should run at low speed. It is necessary to leave the clutch engaged. To maintain the integrity of the structure, any turns of technology must be made smoothly and slowly.

Finally

Whichever device for mowing grass on the backyard is not made with your own hands, it should be safe first. The firm fixing of the knives, the stability of the joints to mechanical loads and the presence of a protective casing is of particular importance when installing the device on a mini tractor or motor-block. In this case, the discs of the mower develop increased revolutions. And this is fraught with damage to the anchorages and the emergence of a potential danger to others.

Before proceeding with the work, it is worthwhile once again to check the mower for the object of the shat on the disks and knives. Promotes the safe operation of the device timely tightening of fasteners, regular maintenance and repair of structural elements.

Proceeding from the foregoing, we can conclude: before proceeding to the manufacture of a self-made rotary mower, it is necessary to reflect on whether there is enough for this purpose of consumables, skills and experience. In some cases, it is much cheaper, more profitable and safer to buy a finished factory assembly mower.
