Limiting the lifting height

The height limit is a useful feature, for example, when there is a risk that the
implement could hit the cabin or when using the power take-off (PTO) driven
implements.
IMPORTANT: The lifting height limitation must be used when using power take-
off (PTO) powered implements to prevent the PTO shaft from being damaged.

1. Lifting height selector
• Use the lifting height selector to limit the lower links' lifting height.
The lifting height can be limited to 9 different positions with the lifting height
selector.
The lifting height selector limits the lifting height when either the position
control knob or the lift/stop/lower switch is used.

Draft control

You can use the draft control when working with implements that operate below
the surface of the ground. The draft control keeps the implement's depth and
draft load constant. This function is useful especially with implements attached to
the three-point linkage. Such implements are, for example, ploughs and
cultivators.
NOTE: It is recommended to keep the draft control disengaged (in position P) if it
is not needed and always when the implement is lifted by the position control
knob.
The draft control has eight levels which define to what extent the draft force
affects the working depth, where
• 1 = small influence
• 8 = very large influence

CAUTION: The lifting height selector does not limit the lifting
height when the lifting/lowering switch or the lifting/lowering push
buttons are used.
