Bush Hog SM 60 Brush Cutter User Manual


 
KEEP CLEAR OF MACHINE WHEN RAISING
AND LOWERING THE CUTTER HEAD.
D. Place cutter deck in desired working position.
E. Engage PTO drive with tractor at idle speed.
Allow 2-3 minutes for hydraulic fluid to warm up.
KEEP HANDS AND FEET FROM UNDER CUT-
TER AT ALL TIMES TO AVOID SERIOUS
INJURY.
F. Set tractor throttle for tractor/implement PTO
speed rating (540 or 1000 rpm).
IT IS RECOMMENDED THAT TRACTOR BE
EQUIPPED WITH ROLLOVER PROTECTIVE
SYSTEM (ROPS) AND THAT A SEAT BELT
BE USED BY THE OPERATOR FOR ALL
MOWING OPERATIONS.
G. Place tractor in gear and begin cutting. Do not
exceed 3 mph forward speed. Use caution when
working along a ditch. If cutter contacts ground,
encounters thick brush, or hits an obstacle, it may
cause tractor front wheels to slide into ditch. For this
reason it is recommended, when cutting in a ditch
where obstacles (i.e. stumps, rocks) cannot be seen,
that the cutter deck be adjusted 2-3 inches above
normal cutting height. Do not stall cutter repeated-
ly or operate in stalled position as overheating
will occur.
IMPORTANT
WHEN USED ON TRACTORS WEIGHING MORE
THAN 10,000 LBS. (4536 KG), CARE MUST BE
USED TO PREVENT BENDING THE SLIDE
ASSEMBLY IF CUTTER DECK STRIKES AN
IMMOVABLE OBJECT.
The cutter deck pivot cylinder is a single-acting
cylinder having hydraulic pressure only for rais-
ing the cutter deck. When working on steep banks
with the cutter on the uphill side of tractor, the cutter
deck can be raised high enough to go over the cen-
ter of gravity. If this happens, the tractor will have to
be driven to more level ground to lower deck. This
condition should be avoided if possible.
Always be aware that cutter deck and counter-
weight box may extend beyond tractor. This is
especially important when working along roads and
traveling through gates and around buildings. A
slow moving vehicle (SMV) sign and tractor warning
lights are recommended for working along highways.
A bracket is provided on weight box for SMV sign.

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 APPROVED
SAFETY SHIELDS THAT ARE IN GOOD REPAIR.
3-3 REVERSING BLADE ROTATION
Some cutting operations may require a counter-
clockwise blade rotation. This may be achieved by
replumbing the reversible motor. Replumbing pro-
cedures are given in paragraph 4-9.
DO NOT OPERATE CUTTER WITH COUNTER-
CLOCKWISE BLADE ROTATION UNLESS CUT-
TER DECK IS EQUIPPED WITH SAFETY CHAINS
AND THE OPERATOR WEAR SAFETY GLASSES
AND SAFETY (HARD) HAT. SAFETY CHAINS
WILL REDUCE AMOUNT OF DEBRIS THROWN
TOWARD OPERATOR. IT IS HIGHLY RECOM-
MENDED THAT OPERATOR BE PROTECTED
WITH ROLLOVER PROTECTIVE SYSTEM (ROPS)
ENCLOSED CAB AND THAT SEAT BELT BE
USED FOR ALL MOWING OPERATIONS.
