Why my the universal cross of my Rotavator gets broken?…

The universal joint assembly is used to rotate the blades of Rotavator. When an untrained operator lifts up the implement from ground while on a turn, he lifts it up too much and does not disengage the PTO.

Remedy

1. Do not lift implement more then 9 inchies from the ground.
2. Fix the position control lever to obtain maximum lift of 9 inchies.
3. Always disengage PTO while lifting up the implement
