1) Machine instability. Machine vibration may be due to the harvesting machine on both sides of the digging shovel swing inconsistency, may also be the digging shovel collision rear gear plate machine vibration. At this time, the machine vibration problem can be solved by adjusting the swing of the digging shovels on both sides, i.e. by adjusting the length of the connecting rod. The connecting rod in front of the triangle belt is responsible for the adjustment of the left digging shovel, and the connecting rod in the middle of the two vertical shafts is responsible for the adjustment of the right digging shovel. When adjusting, lift the harvester off the ground, and make the tractor idle, loosen the connecting rod lock nut, adjust the corresponding connecting rod, pay attention to observe the two sides of the digging shovel swing amplitude, in order to both sides of the deletion of the bar does not touch the guard plate is appropriate, until the adjustment to the swing amplitude is the same, and then lock the nut.

2)The de-soiling is not good. It means that after harvesting peanuts with soil on the ground is not shaken off cleanly, the reason is that the digging shovel into the soil is too deep, resulting in a reduction in the strength of the swing, you can adjust the length of the central tie rod to improve the depth of the digging shovel into the soil. Appropriately shorten the length of the central tie rod, so that the rear end of the deletion bar left the ground 3 to 5cm, can solve this problem.

3)Fruit drop more. Peanut fruits fall on the ground, need to pick up one by one, therefore, once found the phenomenon of falling fruits, need to be resolved in a timely manner. Fruit drop is caused by the digging shovel lifting too high, you can use the method of adjusting the central tie rod to adjust. Contrary to the bad adjustment method of soil removal, the length of the central pull rod can be extended to solve the problem of dropping more fruits.
