7.4 CUTTER BAR BREAK-BACK
When the cutter bar strikes an obstruction while
traveling forward, it will break back against the rotor
actuator. The cutter bar will stay back until you
bump the control hand to return it to the cutting
position. NOTE: The Beak-Away System only
allows the cutter bar to break back. Do not back
the tractor or allow it to roll back with the rear
edge of the cutter bar against an obstruction.
Severe damage to the carriage or other
components may result.
IMPORTANT: Do not slide the cutter bar past the
obstruction. If necessary, back up, adjust the bar to
clear the obstacle and proceed with mowing.
If knife jams or stalls on a large branch or other
debris, it can often be cleared by moving the cutter bar toggle switch to the off position, waiting until the cutter
bar stops, then moving the toggle to the reverse position. This will sometimes clear the jam. If the jam is not
cleared, Idle the tractor, stop the tractor engine, and clear the jam by freeing the obstruction manually. Always
keep fingers, hands and other body parts clear of cutter bar knife. The knife can move suddenly, even with the
tractor engine shut down.
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided.

cause a failure of the equipment and may result in injury.
