PREPARATION FOR USE

2-1 MOUNTING CUTTER ON TRACTOR

A. Check air pressure in tractor tires.

CAUTON

IT IS CRITICAL FOR STABILITY THAT TRACTOR TIRES CARRY PROPER PRESSURE. REFER TO TRACTOR OPERATOR’S MANUAL.

B. Connect cutter to tractor 3-point hitch. Adjust stabilizer bars, sway blocks, or chains. Refer to tractor operator’s manual.

CAUTON

USE OF THIS MACHINE ON TOO SMALL A TRACTOR CAN CAUSE TRACTOR UPSET. DO NOT USE THIS MACHINE ON A TRACTOR WEIGHING LESS THAN 6000 LBS. (2722 KG) NOT INCLUDING BALLAST. IT IS RECOMMENDED THAT FRONT BALLAST BE USED FOR ADDED STEERING STABILITY. THIS MACHINE REQUIRES 50 PTO HORSEPOWER.

C. If valve kit is used, mount valves on tractor as desired. If optional valve mounting brackets are used, attach brackets and valve to tractor as described in paragraph 5-6. Make certain all hoses are free of sharp bends, creases, or moving parts. It is recommended that valves be mounted on right side of tractor.

D. Connect hoses to hydraulic quick disconnects on rear of tractor.

E. Raise and lower implement to determine the shortest distance between the tractor PTO shaft and pump input shaft. Stop tractor leaving implement in position of shortest distance. Block implement in position.

STAY CLEAR OF DECK DURING AND AFTER

REMOVAL OF LOCK PIN. AIR INHYDRAULIC

LINES COULD ALLOW CUTTER DECK TO

FALL, CAUSING POSSIBLE INJURY.

M. Position cutter deck straight out (parallel to ground) and approximately 2 inches (51 mm) from ground.

N. Adjust cutter deck front to rear using top link of 3-point hitch. Rear of cutter deck should be 1-2

inches (25-51 mm) higher than front.

O. Adjust lower 3-point hitch arms to level cutter deck sliding beam right to left.

P. Adjust 3-point hitch position control to stop at present height. This will prevent accidental dragging of sliding beam.

Overlap Minimum

WARNING

Transport Lock Pin

Q. If equipped with optional valve stand, adjust to

desired working position.

R. Raise cutter deck and install transport lock pin

before traveling. (Fig. 2-3)

NOTE It is recommended that front end ballast (weights) be added to tractor for stabilization. In some uses, added stabilization may be gained by weighting left rear wheel heavier than right rear wheel. Do not exceed tractor ballast rating. Consult your tractor dealer.

2-2 DRIVELINE MODIFICATION

IMPORTANT

IT IS EXTREMELY IMPORTANT THAT DRIVELINE MATCH THE TRACTOR BEING USED. IF UNIT IS ATTACHED ON ANOTHER TRACTOR, DRIVELINE MUST BE CHECKED FOR CORRECT LENGTH. FAILURE TO MATCH DRIVELINE TO TRACTOR WILL CAUSE FAILURE TO THE PUMP.

Due to the many variations in tractor/implement hitch points and corresponding differences in distances between tractor PTO shafts and implement input shafts, drivelines may need to be shortened as follows:

A. Attach implement to tractor 3-point hitch.

B. Raise and lower implement to determine the shortest distance between the tractor PTO shaft and the pump input shaft. Stop tractor leaving implement in position of shortest distance. Block implement in position.

C. Pull driveline apart. Attach the outer (female) section to the tractor PTO shaft and the inner (male) section to the pump input shaft. Pull on each driveline section to make sure yokes lock into place.

D. Hold driveline halves parallel to each other to determine amount to be removed. Measure approximately 3 in. (76 mm) back from the opposite universal joint shield and mark the free end of the shield. Do this for each section. (Fig. 2-4)

E. Clamp the end of driveline in a vice. Cut off shield at point it was marked.

F. Using the cut off section of shield as a guide, cut the shaft the same amount. (Fig. 2-6)

Page 12

G. Repeat steps “E” and “F” to other driveline sec-

tion.

H. De-burr the ends of the drivelines and clean

away all chips and filings. (Fig. 2-7)

I. Apply grease to inside of outer (female) driveline

Figure 2-4

Figure 2-6 Figure 2-7

section. Reassemble driveline and attach to tractor and implement. Pull on driveline section to make sure yokes lock into place.

J. Raise and lower implement to check for proper

operation. Figure 2-5

SECTION III

OPERATING PROCEDURES

3-1 TRACTOR REQUIREMENTS AND

RECOMMENDATIONS

3-1.1 Requirements The tractor shall weigh a minimum of 6000 lbs. (2722 kg) not including ballast to prevent tractor upset. A PTO rating of not less than 50 horsepower

is required. The 3-point hitch shall have stabilizer bars, sway blocks, chains or equivalent to prevent mower swaying. Tractor rear wheel base (outside of tire to outside of tire) shall not exceed 92 inches (233.7 cm).

3-1.2 Recommendations

Tractor should have front end ballast (weights) to help prevent front end skidding. Tractor should be equipped with Rollover Protective System (ROPS) and a seat belt used. Check chains for 3-point hitch are recommended on tractors without position control stop adjustment to prevent accidental dragging of slide assembly on ground.

WARNING

WHEN CUTTING WITH ANY SIDE MOUNT ROTARY CUTTER, IT IS LIKELY THAT SOME DEBRIS WILL BE THROWN TOWARD OPERATION. IT IS HIGHLY RECOMMENDED THAT OPERATOR BE PROTECTED BY ROLLOVER PROTECTIVE SYSTEM (ROPS) ENCLOSED CAB AND CUTTER DECK BE ENCLOSED BY FACTORY APPROVED PERMANENT BANDS OR SAFETY CHAINS. THE OPERATOR SHOULD WEAR SAFETY GLASSES AND SAFETY (HARD) HAT FOR PERSONAL PROTECTION.

3-2 OPERATION

A. Perform BEFORE EACH USE maintenance

listed in Table 4-1.

B. Make certain parking stand is pinned in the

up position. (Fig. 2-2)

C. Remove deck transport lock pin and place in

storage holes. (Fig. 2-3)

Page 13

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 CUTTER 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 raising 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 center 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.

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, SAFETY CHAINS, OR OTHER FACTORY APPROVED SAFETY SHIELDS THAT ARE IN GOOD REPAIR.

3-3 REVERSING BLADE ROTATION

Some cutting operations may require a counterclockwise blade rotation. This may be achieved by replumbing the reversible motor. Replumbing procedures are given in paragraph 4-9.

WARNING

DO NOT OPERATE CUTTER WITH COUNTERCLOCKWISE BLADE ROTATION UNLESS CUTTER 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 RECOMMENDED 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. G. Shut down tractor.

Figure 3-1 Parking Stand

Always be aware that cutter deck and counterweight 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.

4-10 TROUBLESHOOTING

Cleanliness is of primary importance for obtaining satisfactory life of hydraulic components. The life of

hydraulic components is dependent upon the degree of contamination in the hydraulic oil.

During usage, proper oil filling and servicing of filters, breather, tank, etc., cannot be over emphasized.

The hydraulic system must be cleaned after a major

contamination such as pump failure. This requires removal and individual flushing and cleaning of all components and lines that were exposed to the contaminated oil flow. Flushing of the system

components should be done with a suitable solvent or diesel fuel. Clean the suction strainer,

replace the return line filter, and refill tank with new hydraulic oil.

Troubleshooting procedures are listed in Table 4-4. If the problem cannot be solved or replacement parts are necessary, contact your authorized Bush Hog dealer. Please have ready your machine name, serial number, model number, purchase date, and exact cause or description of problem.
