Bush Hog SM 60 manual 3-3REVERSING BLADE ROTATION, 3-4PARKING

WARNING

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.

DANGER

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).

WARNING

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.

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 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.

WARNING

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.

3-4 PARKING

A. Apply tractor parking brake. B. Disengage PTO drive.

C. Slide cutter deck in.

D. After all blade motion has stopped, raise and pin cutter deck in the travel position. (Fig. 2-3)

WARNING

KEEP CLEAR OF MACHINE WHEN RAISING AND LOWERING THE CUTTER HEAD.

E. Pin stand in the down position. (Fig. 3-1) F. Lower implement to rest on ground.
