ROTARY CUTTER OPERATION
STEP 1
Before each use, perform the maintenance described in maintenance section.
STEP 2
Read, understand, and follow the information on safety, preparation, starting
and stopping safety, operational safety and transport safety warning sections
of this manual.
STEP 3
With tractor running, lower the Rotary Cutter into it's working position.
STEP 4
With the tractor at idle RPM, engage PTO and slowly advance throttle to
approximately 540 PTO RPM.
NOTE: The Rotary Cutter was designed to run at 540 PTO RPM.
STEP 5
Select a low tractor gear and begin to mow. Tractor ground speed is to be
controlled by gear selection only and not engine speed. Tractor PTO speed
should allow the Rotary Cutter to maintain 540 PTO RPM and thus maximum
blade tip speed.
NOTE: Do not allow the tractor engine or the Rotary Cutter to bog down or stall.
This causes unnecessary wear and tear on the mower and tractor. If this
continues to occur, reduce ground speed and/or raise the cutting height
of the Rotary Cutter.
NEVER ATTEMPT TO CLEAN OUT A CLOGGED DISCHARGE CHUTE
UNTIL THE MOWER BLADES HAVE COMPLETELY STOPPED AND THE
TRACTOR HAS BEEN SHUT OFF.
STEP 6
After each use, clean all debris from the top and bottom of the Rotary Cutter.
Replace any missing or illegible safety decals. Inspect for any damaged or worn
parts and replace before next use. Store the Rotary Cutter in a dry environment.
