This product is used for tractor traction and rotary disc mower transmission gearbox cutter beams. It is derived from European and American design concepts. It transmits the GC128 gearbox and GC100 gearbox through the tractor input, and the link transmission shaft drives the cylindrical gear to the cutter head. , the tool beam uses a full gear structure design and the output speed is 3000 rpm. The transmission noise is low, and the quality is more stable and reliable. This machine is a final combination of 3 products. The GC128 gearbox is the front traction, achieving 360° free rotation. The turning radius is less than 90° during operation. This knife beam is available in 7-disc and 8-disc models. The 420mm increased center distance design allows the same model to have a larger operating cutting width. The 7-disc is 3.2 meters, and the 8-disc is 3.6 meters. At the same time, the lawn mowing and flattening function can also be realized. Used for harvesting alfalfa, safflower, and other crops. Flattening the stems will help to absorb moisture and help them dry in the sun.
