Universal joints to prevent damage to Rotary Tiller: rotation to the damaged section of the main reasons, first, improper use, the second is not installed correctly, the three universal joint shaft and sleeve is the inappropriate choice of 4 is not in a timely manner as required for maintenance, five is the edge of a turn does not improve or did not wait to bring it forcibly turn.

For the above reasons, may take the following measures:

Stones and more land should not use rotary tiller, it is best to use other farming equipment; first started farming machines Wan and bonding power, and then slowly falling tools, so that rotary tiller blade buried in the forward slowly; use of universal section of the square shaft and sleeve length should be matched with the tools model, if too long, in use will top the bad transmission parts, is too short then the tools will be raised when the prolapsed; joints installed, open the folder should be in the same fork plane, in order to ensure uniform spindle rotation force, or transmission parts are easily damaged; time required for lubrication and maintenance, grease all lubrication points do not miss the grease to prevent damage due to dry friction and early; tools to upgrade should be a high degree of hydraulic control lock, rotary knife above ground shall not exceed 20cm; turning tools must be improved, or easily damaged transmission parts; at work, and gearbox shaft universal joints square plane angle shall not exceed 10 degrees, or decreased transmission efficiency, and easily damaged, tools to upgrade after the angle can not exceed 30 degrees, otherwise it is easy to damage the joints.
