OPERATION

DISC MOWERS ARE NOT INTENDED FOR ROADSIDE OR MUNICIPAL MOWING. THEY
ARE INTENDED FOR AGRICULTURAL USE ONLY. DO NOT OPERATE MOWER NEAR
STRUCTURES WHICH MAY BE VULNERABLE TO DAMAGE FROM THROWN OBJECTS.
THE OPERATING TRACTOR SHOULD BE EQUIPPED WITH AN ENCLOSED CAB!
BEFORE STARTING OPERATION, MAKE SURE THE COVER SHEET IS IN GOOD SHAPE
AND IN THE LOWERED POSITION. DO NOT OPERATE THE MOWER WITHOUT THE
COVER SHEET IN PLACE! AND IN THE LOWERED POSITION
IMPORTANT: After transporting the mower and before beginning field work, lower the cutting bar
to the horizontal position, engage the PTO drive and run the tractor at idle for several minutes to
lubricate all internal parts. Place the tractor hydraulic valve in float position so the mower can
follow the terrain.
BEFORE STARTING OPERATION, MAKE SURE THERE ARE NO PEOPLE OR ANIMALS IN
THE VICINITY OF THE MOWER.
DO NOT ENGAGE THE PTO WITH THE TRACTOR RUNNING AT HIGH SPEED. DRIVELINE
DAMAGE MAY OCCUR.
OPERATE MOWER AT 540 RPM ONLY. HIGHER INPUT SPEEDS MAY RESULT IN
COMPONENT FAILURE.
1. Engage the PTO drive and gradually increase the speed to 540 RPM. Only enter the crop
when the mower is operating at 540 RPM. Do not reduce PTO RPM below 540 when mowing
as this may cause plugging. If necessary to slow RPM, stop forward movement then reduce
RPM.
2. Start the forward motion of the tractor. The high speed cutting ability of the Disc Mower allows
faster ground speeds. Generally ground speed of 4 to 6 MPH will yield good results. Match your
speed to the terrain and slow down on hilly or uneven ground. Reduce speed if the mower leaves
uncut material. To mow neatly while turning corners, the ground speed will need to be reduced.
3. Cut around the field in a clockwise direction. On RH corners slow ground speed and turn
sharply with mower bar in contact, with the ground to achieve square corners, It is necessary to
raise the bar slightly when making LH turns. LH turns with the bar in contact with the ground may
cause the breakaway to unlatch or lead to bar damage.
4. Maintain full RPM when running over previously cut material. Reduced RPM may cause plug-
ging in these conditions.
5. In some field conditions, such as newly seeded fields, dirt or debris may build up between the
rock guards. Build up in this area may cause streaking, leaving uncut strips. Clean the cutterbar
frequently to prevent premature knife wear.
6. When mowing is finished, gradually reduce PTO speed and disengage the PTO drive.
