Attention, danger of injury!
Causes of overload may only be removed after disconnection of
the control system from power supply (interrupt electric
connection to tractor), when the tractor motor has been stopped
and the ignition key removed!
8.10.1 Drive shaft with shear bolt yoke*
A shear bolt yoke is inserted at the machine side into the drive
shaft.
The bolt [1] shears off at overload and must be replaced by
a new one.
Do not restart the machine unless the source of the overload
is removed.

Shear bolt with nut ................................................ 0930.84.53.00
8.10.2 Drive shaft with cam-type cut-out clutch*
In the event of overload the cam-type cut-out clutch interrupts
the driving torque.
Switch off power take-off shaft and remove cause of
overload.
After switching on the power take-off shaft, the torque builds
up again so that the machine can be put into operation.
Avoid long and frequent overloads. Make sure, that only the
corresponding drive shaft is used.
