DANGER

ROTATING CUTTER BLADES. STAND CLEAR UNTIL ALL MOTION HAS STOPPED. TO AVOID AN ACCIDENTAL FALL FROM THE TRACTOR AND POSSIBLE INJURY BY THE MOWER, IT IS RECOMMENDED THAT THE TRACTOR BE EQUIPPED WITH ROPS (ROLLOVER PROTECTIVE SYSTEM) AND THAT A SEAT BELT BE USED BY THE OPER- ATOR FOR ALL MOWING OPERATIONS.

F. Place tractor in gear and begin cutting. Tractor for- ward speed should be controlled by gear selection, not engine speed. For maximum cutting efficiency, for- ward speed should allow cutter to maintain a constant, maximum blade speed. Do not exceed 5 mph (8kph). If PTO drive is disengaged due to cutter stalling or tractor engine bogging, cutter must be moved to a “cut” area and tractor throttle reduced to idle before re-engaging. Always cut up and down the face of slopes, never across.

WARNING

ALL ROTARY CUTTERS HAVE THE ABILITY TO DISCHARGE OBJECTS AT HIGH SPEEDS WHICH COULD RESULT IN SERIOUS INJURY TO BYSTANDERS OR PASSERS-BY.

THEREFORE, THIS CUTTER IS NOT TO BE OPERATED ALONG HIGHWAYS OR IN ANY AREA WHERE PEOPLE MAY BE PRESENT UNLESS ALL SIDES OF THE UNIT ARE ENCLOSED BY PERMANENT BANDS, SAFE- TY CHAINS, OR OTHER FACTORY APPROV- ED SAFETY SHIELDS THAT ARE IN GOOD REPAIR. CEASE MOWING WHENEVER ANY- ONE COMES WITHIN THE OPERATING AREA.

3-4 TRANSPORTING

When implement is transported on road or highway, day or night, use tractor flashing warning lights unless prohib- ited by law. A slow moving vehicle (SMV) sign must be visible from the rear by approaching vehicles. Do not exceed 15 mph (24kph) when traveling. Fully raise implement before transporting.
