4. Hydraulic lift linkage stroke limiters
Kit no. 1246040
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.
- Fit the stroke limiters to the hydraulic lift linkage.
- Install the 4 washers.
- Insert and lock lynch pins (1) of each pin.
- Tighten the assembly using nut (2).
Machine use
By fitting the hydraulic attachment stroke limiters, the
additional machine's lift height can be controlled.
By removing the stroke limiters, the additional machine
can be fully raised.
This equipment 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.
