Rotary Rake

Rotary rake is an important machinery for forage harvesting, mainly used to turn the cut down forage for drying, gathering and spreading operation. It is through the rotation of the raking teeth or teeth will spread the grass gently turned, so that it is uniformly drying, at the same time the sun-dried pasture grass into a neat strip of grass, easy to follow the baling or silage collection. The modern raking machine adopts hydraulic or traction power, with large working width and high efficiency, which can effectively reduce the nutrient loss of forage and maintain the quality of forage. According to the operation mode can be divided into roller type, finger plate type, rotary type and other types, can be adapted to the plains pasture, but also in the slope operation, is an indispensable machinery and equipment for modern ranch.

Repair method

Repair of damaged rake teeth:  the rake teeth are bent or broken, the rotary rake needs to be separated from the traction equipment. For bent rake teeth, a large-size wrench or a special straightening tool can be used. After fixing the root of the rake teeth, slowly apply force to straighten them. the rake teeth are broken, remove the damaged rake teeth and replace them with new rake teeth with matching specifications.

Repair of transmission component failure: it makes abnormal noise or jams during operation, there is a problem with the transmission components such as chains, sprockets, and universal joints. Check whether the chain is loose, worn, or broken. the chain is loose, adjust the tensioner;  the chain is severely worn or broken, a new chain needs to be replaced. For universal joints, add grease in time when oil is lacking, and replace new universal joints damaged.

Bearing fault handling: the rotating shaft of the rotary rake is severely heated or has abnormal noise, it may be a bearing damage. First clean up the debris, use appropriate tools to remove the bearing end cover, and remove the old bearing. Check whether the bearing ball and raceway are worn, deformed, or cracked, and select a suitable new bearing.

Special design

1.Tine arm configuration

The tine arms of a rotary rake rotate around a vertical axis, lifting and moving hay or crops. The ability to collect hay reduces soil contamination and provides better quality feed for livestock.

2.Adjustable working width and height

It has an adjustable working width and height. Depending on crop density, field conditions and desired windrow size, the operator can modify these settings to increase efficiency and production.

3.Hydraulic controls for operation

It also has hydraulic controls for adjustment and operation. The operator can raise or lower the rake and adjust the working width.
