Or take a rotor from a tractor and reduce it based on the power of your walk-behind tractor.

The working elements are knives that are mounted on disks cut from a metal sheet. They are fastened as follows: an axial shaft (pipe) is welded in the center of the circles, a bearing is installed on it, and another bearing is mounted on the pulley.

Working units with knives are put on the axle, rotation is easy due to bearings, grass capture varies up to a meter, approximately. The finished structure is mounted on a welded chassis with wheels and covered with a casing on top. A homemade brush cutter can be either single-disc or double-disc.

Service Features

One of the main advantages of rotary models is that they require virtually no technical knowledge for operation and maintenance. Farmers choose such equipment because of its simplicity of design and the absence of the need for frequent repairs. You will need to monitor the condition of the device, because spare parts for trailed mowers wear out over time and require replacement or maintenance. The repair is simple and can be done by one person.

For efficient operation, lubricant and parts are checked for malfunction or damage, and components and chains are adjusted.

The need for frequent maintenance of a segment mower depends on its model. Attachments for large equipment may require this on a daily basis and at the end of the working season. The mower for any tractor is cleaned of dirt, grass and other things, and the reliability of fastening the knives of the cutting plate is checked. Periodically, the elements will need to be sharpened or replaced, and lubrication is also required. A segment mower is more difficult to maintain because it has a more complex structure and a labor-intensive hanging process.
