Disc mower
Tractor not fitted with a hydraulic position
control function:
- Lower the tractor lift to obtain a distance of H = 450
mm (1’6’’) between the Hitch pin axis and the
ground:
• Insert hook (1) in check chain link corresponding
to the required frame height and lock using roll pin
(2).
- Attach each check chain with its hook supplied
with the machine to one of the upper free holes at
the tractor's top link attachment clevis.
- Lower the machine until the check chain is under
tension.
The tractor lift linkage is in working position.
The height is correct when:
• The cutterbar is resting on the ground.
• The check chain is under tension.
• The distance H equals 450 mm (1’6’’).
• The 2 hitch pins are parallel to the ground.
Safety breakback
On hitting an obstacle, the safety breakback causes
the cutterbar to pivot rearwards.
- If the machine hits an obstacle, disengage
the PTO drive, stop the tractor engine,
remove the ignition key and wait for all
moving parts to come to a complete
standstill.
- In case an obstacle has been struck, check
that the mowing unit has not been
damaged.
