Select a gear range that will allow the cutter to make a
smooth cut without lugging the tractor down.
See

enough to get the cutter started without stalling tractor

that the cutter is not vibrating excessively after
ramping up to power take-off speed for at least 3
seconds. If excessive vibration continues after 3
seconds at full power take-off speed, disengage
power take-off immediately, shut down tractor and
remove switch key. Wait for blades to come to a
complete stop before dismounting tractor.
4. Investigate cause if cutter was shut down due to
excessive vibration. See
on page 32 for detailed instructions.
5. If cutter was not shut down, commence forward
cutting operation at full power take-off operating
speed. Make a new gear selection if tractor is lugging
down or if cutter is making a rough cut.

to do an inspection. Refer to
on page 17 for proper shut down
procedure.
