1. The correct installation of crawler belts uses the jack to lift the combine harvester frame, loosen the crawler tightening device, and put the crawler belt into the traveling mechanism composed of driving wheels, supporting wheels, balancing wheels, supporting belt pulleys and guide wheels. Then tighten the track. Be sure to grasp the tightness of the track when tightening the track. The track is too tight, the power loss of the combine harvester is large, the track wear is aggravated, the track pitch is widened, and the belt body is easily cracked, which may affect the service life of the track. The crawler belt is too loose, and the joint harvester will experience tooth skipping when walking. Easy derailment affects both steering and normal driving. 2. Correct use of track (1) It is forbidden to make a sharp turn on a concrete floor or a hard surface. Otherwise, the track core will be worn and the belt body will be twisted. (2) When crossing the field, it must be at a right angle with Tian Hao at a low speed. The spandrel that spans more than 10 cm in height must use a springboard, otherwise the crawler can easily fall off or be damaged. (3) It is forbidden to walk and make sharp turns on the gravel road for a long time, otherwise it will speed up the wear of the crawler belt and cause crawler cracks. (4) Do not work on bad farmland. Otherwise, it will introduce track slipping and make the walking body muddy and wrap around, which will affect normal work. (5) If stone or foreign matter enters between the crawler and undercarriage, the operation shall be immediately stopped and stones or foreign objects shall be removed. (6) Wash the track promptly after working on the beach or in a field sprinkled with chemicals.
