5. The implement cardan shaft end yokes from the side of PTO shaft and PRS shall
lie in the same plane as indicated in Figure 5.6.1.
6. Safety clutch, as indicated in Figure 5.6.2, shall be installed only from the side of
PRS of the drive of the implement coupled; other methods of mounting will not ensure
timely protection of the tractor PTO shaft from excess of the maximum permissible torque.
After lengthy downtime check the implement safety clutch for technical condition.
7. Mounting of the cardan shaft with guard casing together with protective devices
of PTO shaft and PRS, with retaining chains both from the side of the PTO shaft and of the
PRS, as indicated in Figure 5.6.3, and ensures cardan joint safety.

ed.
9. The length of the cardan shaft maximum driven apart, which is permitted for op-
