Power harrows

HR4004D - 4504D
Optional equipment
Hydraulic stroke limiting device:
Adjustment
- Couple up the PTO shaft (between the power harrow
and the additional machine).
- Lift the combined machine using the rear hydraulic lift
linkage:
• When the PTO shaft is in its maximum overlap
position (retracted), tubes should not butt against
the yokes. As a safety measure, a clearance (L) of
at least 25 mm (1’’) must be maintained.
- Keep hydraulic valve lever (3) in the off position and
position a link of chain (1) in holder (2) so that chain is
tensioned.
Machine use
By fitting the hydraulic attachment stroke limiter chain,
the additional machine's lift height can be controlled
when making headland turns.
By removing the hydraulic attachment stroke limiter
chain, the additional machine can be fully raised.
This device prevents damage to the PTO
transmission shaft when lifting an additional
implement which is PTO driven.
If the power harrow is used with an additional
PTO driven machine, make sure to uncouple
PTO shaft before fully raising the additional
machine.
