The domestic market of agricultural machinery presents a whole host of effective solutions for working on personal plots and lawn care. Rotary mowers are in the highest demand today. Such devices are distinguished by high performance, ease of use, the ability to install on a tractor and walk-behind tractor. Due to the special simplicity of the design, if desired, a home-made rotary mower can also be made.
Let's look at the design features, the principle of operation and how to independently assemble grass mowing, weeding and lawn care equipment.
Working principle
The operation of a rotary mower is based on the reproduction of rotational movements on the working shaft. Knives are attached to the latter, the block of which resembles a rectangular bar in shape. This structure ensures consistent grip and thorough cutting of plants.
Rotary mowers have become widespread due to their efficiency. To set the rotating knives in motion, energy is used here, which is supplieddirectly from traction equipment. Therefore, their operation does not require additional fuel consumption or the creation of a separate connection to the centralized power grid.
Types
There are several varieties of rotary mowers:
- trailed;
- mounted;
- semi-mounted.
Both the factory and homemade trailed type mower is attached to the transport using a three-point hitch. This makes it possible to change the angle of inclination of the cutting mechanism relative to the surface being processed.
Hinged homemade mower for walk-behind tractor is statically mounted on a mini-tractor using standard mounts. Due to its special compactness, it is ideal for cultivating land plots that are rather modest in area.
As for the semi-attachments, the latter are not very wide possibilities for adjusting the position of the knives. At the same time, such devices are designed for mowing grass over large areas.
Features of operation
A homemade rotary mower can be effectively used by owners to mow tall grass, which is planned to be laid in rollers for drying. Some devices in this category are not only capable of forming even rows of mowed plants, but are also suitable for thoroughly crushing them.
Homemade rotary mower
Forhand-made rotary mower, it is necessary to prepare the knives, which will be sequentially placed on the disc circles. A power shaft must be used as a means to ensure rotation. The basis for creating the frame of the future fixture will be iron corners. Use of old scrap metal is allowed.
Progress of work
Homemade mower is made as follows:
- For the construction of the rotor, a metal sheet is prepared, from which two disks with a diameter of about 40 cm are cut. Save on the purchase of material will use an alternative in the form of a bottom from an old bucket or barrel.
- Any metal pipe with a cross section of about three cm will serve as an axial shaft.
- To ensure the rotation of the structure, the shaft will need to fit on the bearings. Subsequently, discs are put on it, to which cutting knives are pre-welded.
- Then, using the same welding machine, the mechanism is attached to the metal frame.
- The mower is equipped with a protective cover that will ensure safety during work.
- Finally, the shaft of the structure is equipped with wheels.
Such a device will allow you to mow plants at a speed of up to about 10-12 km / h. With the acceleration of movement, the grass will turn out to be more crushed, in the case of unhurried work - integral. The device is ideal for cleaning the garden plot or home garden from weeds.
Homemade mini tractor mower
It is one thing to assemble a practical rotary mower with your own hands, it is quite another to correctly attach it to the tractor. During installation, pay attention to the following points:
- The tractor or walk-behind tractor must be switched to work in the "Reverse" mode.
- The rotational shaft of the equipment is mated with the mower shaft.
- During installation, it is advisable to close the knives with a protective cover.
- The wheels of most models of walk-behind tractors contain loads that contribute to more thorough soil cultivation. When equipping equipment with a rotary mower, the latter are useless. Therefore, they must be removed.
First, a homemade tractor mower should run at low speeds. In this case, it is necessary to leave the clutch engaged. To maintain the integrity of the structure, any turns of the equipment must be made smoothly and slowly.
In closing
Whatever device for mowing grass on a personal plot is made with your own hands, it must first of all be safe. Strong fastening of knives, resistance of joints to mechanical stress and the presence of a protective cover are of particular importance when installing the device on a mini-tractor or walk-behind tractor. In this case, the mower discs develop increased speed. And this is fraught with damage to the fasteners and the emergence of a potential danger to others.
Before starting work, it is worth once againcheck the mower for slack on discs and blades. Timely tightening of fasteners, regular maintenance and repair of structural elements contributes to the safe operation of the device.
Based on the foregoing, we can conclude: before proceeding to the manufacture of a home-made rotary mower, it is necessary to consider whether consumables, skills and experience are enough for this. In some cases, it is much cheaper, more profitable and safer to purchase a factory-assembled mower.
