Bush Hog 306 Brush Cutter User Manual


 
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.
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.
