4.9.1 General information
WARNING
Loss of the implement
The tractor's three-point linkage category and the category of the
draw rail and top link pin must match. Otherwise, the draw rail and
the top link pin may slip out of the linkage when driving over un-
even ground or due to vibrations.
• Always ensure that the three-point linkage category exactly
matches the diameter of the draw rail and the top link pins.
The maximum permissible tractor outputs and dimensions as per ISO 730-1 for
the corresponding category are available in the following table.
