Loss of the implement
The category of the tractor’s three-point linkage and the category
of the cross shaft and top link pin must correspond. Otherwise the
cross shaft and top link pin may slip out of the linkage as a result
of vibration or when travelling on uneven ground.
Ensure that the category of the three-point linkage precisely
matches the diameter of the cross shaft and the top link bolt.
The maximum permissible tractor outputs and dimensions for each category ac-
cording to ISO 730-1 are shown in the table below:
