In the domestic market of agricultural machinery, a whole host of effective solutions for working on personal plots and lawn care is presented. The highest demand today is rotary mowers. Such devices are characterized by high performance, ease of use, the ability to install on a tractor and walk-behind tractor. Due to the particular simplicity of the design, a home-made rotary mower can also be made if desired .
Let's look at the design features, the principle of operation and methods of self-assembly of devices for mowing grass, harvesting weeds and lawn care.
Principle of operation
The operation of the 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 beam in shape. Due to this structure, consistent capture and careful cutting of plants is ensured.
Rotary mowers are widely used due to their efficiency. To bring the rotating knives into motion, energy is used here, which is supplied directly from the traction equipment. Therefore, to ensure their functioning does not require additional fuel consumption or the creation of a separate connection to a centralized power grid.
Types
There are several varieties of rotary mowers:
- trailed;
- mounted;
- semi-mounted.
Both factory and home-made trailer-mounted mowers are connected to vehicles using a three-point mount. This makes it possible to change the angle of inclination of the cutting mechanism relative to the work surface.
Mounted homemade mower for walk -behind tractor statically mounted on a mini-tractor using standard mounts. Due to its special compactness, it is ideally suited for cultivating land plots of rather modest size.
With regard to semi-mounted devices, the latter are not very wide possibilities for adjusting the position of the knives. At the same time, such devices are intended for mowing grass in areas of significant area.
Operational Features
A home-made rotary mower can be effectively used by the owners to mow tall grass, which is planned to be laid on rollers for drying. Some devices of this category are capable of not only forming even rows of mowed plants, but are also suitable for their thorough grinding.
Homemade rotary mower
For the manufacture of rotary mowers with their own hands, it is necessary to prepare knives that 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 the frame of the future fixture will be the iron corners. Use of old scrap metal is allowed.
Progress
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. To save on the purchase of material will allow the use of an alternative option in the form of a bottom from an old bucket or barrel.
- An axial shaft will be any metal pipe with a cross section of about three cm.
- To ensure the rotation of the structure, a shaft fit on the bearings will be required. Subsequently, disks are put on it, to which cutting knives are pre-welded.
- Then, using the same welding machine, the mechanism is attached to a 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 mowing plants at a speed of up to about 10-12 km / h. When accelerating movement, the grass will turn out to be finer, in case of leisurely work - holistic. The device is ideal for cleaning weeds and gardens.
Homemade mower for mini tractor
It’s one thing to assemble a practical rotary mower with your own hands, it’s completely different to correctly attach it to a tractor. During installation, you should pay attention to the following points:
- The tractor or walk-behind tractor must be transferred to work in the "Reverse" mode.
- The rotary shaft of the machine is coupled with a pass connection to the mower shaft.
- During installation, it is advisable to close the blades with a protective cover.
- The wheels of most models of walk-behind tractors contain loads that contribute to a more thorough tillage. When completing the equipment with a rotary mower, the latter are useless. Therefore, they need to be removed.
First, a makeshift tractor mower should run at low revs. In this case, leave the clutch engaged. To maintain the integrity of the structure, any turns of the equipment should be carried out smoothly and slowly.
Finally
Whatever device for mowing grass on a personal plot was made by one’s own hands, it should be safe in the first place. Strong knives fastening, stability of joints to mechanical loads and the presence of a protective casing is of particular importance when installing the device on a mini-tractor or walk-behind tractor. In this case, the discs of the mower develop an increased speed. And this is fraught with damage to the mounts and the occurrence of potential danger to others.
Before proceeding with the work, it is worth checking the mower once again for the shaw on the disks and knives. Promotes the safe operation of the device, timely tightening of the fasteners, regular maintenance and repair of structural elements.
Based on the foregoing, we can conclude: before proceeding with the manufacture of a home-made rotary mower, it is necessary to consider whether there are enough expenditures, skills and experience for this. In some cases, it is much cheaper, more profitable, and safer to purchase a factory-assembled mower.
