Safety breakback
On hitting an obstacle, the safety breakback causes the
cutterbar to pivot rearwards.
The safety breakback is reset by reversing (a).
If the safety breakback releases after reset, tighten
screw 1 to increase spring washer compression.
Basic adjustments:
L= 96 mm (3.8’’)
A= 20 times 2 washers.
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.
