The category of the three-point linkage on the tractor and the cat-
egory of the cross shaft and top link pin must correspond, other-
wise the cross shaft and top link pin may slip out of the connection
when travelling on uneven ground or as a result of vibration.
Always ensure that the category of the three-point linkage and
the diameter of the cross shaft and top link pin are exactly the
same.
The maximum permissible tractor power and dimensions for each category in ac-
cordance with ISO 730-1 are set out in the table below.
