Front & Rear Deflectors Belting is standard, chain deflectors are optional Wheels Laminated Laminated Laminated Approximate Weight (lbs.) 794 lbs. 1, 2 962 lbs. 1, 2 1247 lbs. 1, 3 1 - Weight includes deflector chains front & rear, 2 - Single tailwheel, 3 - Dual tailwheel SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICE 7 SECTION II PREPARATION FOR USE 2-1 ATTACHING TO TRACTOR WARNING NEVER STAND BETWEEN TRACTOR AND CUTTER WHILE TRACTOR IS BEING BACKED TO HITCH. WARNING ADDITIONAL TRACTOR FRONT BALLAST MAY BE NEEDED FOR STABLE OPERATION AND TRANSPORT OF THE 3-POINT HITCH MOUNTED CUTTER. SEE TRACTOR OPERATOR’S MANUAL FOR RECOMMENDED WEIGHTS. WARNING DO NOT USE PTO SHAFT ADAPTERS TO CHANGE SIZE OF TRACTOR PTO SHAFT. THE CORRECT DRIVELINE MUST BE USED TO MATCH TRACTOR PTO SHAFT. A. Attach cutter to tractor 3-point hitch per tractor operator’s manual. Do not attach driveline at this time. IMPORTANT Tractor top link pin securing 3-point hitch top link to cutter must conform to dimension shown in Figure 21 to avoid interference with A-frame. Figure 2-1 Top Link Pin 5-1/2” 3-3/4” 3-3/4” QUICK HITCH ASSEMBLY 5/8 X 5-1/2” Capscrews w/ 2-3/8” Bushing 1 x 4-1/2” Capscrew w/ 1-1/4” Bushing 3/4 x 4” Capscrew w/ 1” Bushing Lower Hitch Pin w/ Cat. I & Cat. II Bushings 3/4 x 2-1/2” Capscrews w/ 1” Bushing NOTE Due to the many variations in tractor / imple ment hitch points and corresponding differ ences in distances between tractor PTO shafts and implement input shafts, drivelines may need to be shortened as described in the following steps: D. Raise and lower cutter to determine position with shortest distance between the tractor PTO shaft B. Raise 3-point hitch until front of cutter is approximately 1-2 inches (25-51mm) lower than rear for standard cut or until front of cutter is 1 inch (35mm) higher than rear for extra shredding. Shut down tractor. Securely block cutter in position. For further explanation of cutter adjustment, see paragraph 3-2. C. Adjust top link of 3-point hitch to position flex link as shown in Figure 2-2. Figure 2-2 Flex-Link and gearbox input shaft. Shut down tractor leaving cutter in position of shortest distance. Securely block cutter in position. E. Pull driveline apart. Attach outer (female) section to tractor PTO shaft. Pull on driveline section to be sure that yoke locks into place. F. Hold driveline sections parallel to each other to determine if too long. Each section should end approximately 3 inches (76mm) short of reaching universal joint shield on opposite section. If too long, measure 3 inches (76mm) back from universal joint shield and mark on opposite section. (Figure 23). Do this for both sections. G. Raise and lower cutter to determine position with greatest distance between PTO shaft and gearbox input shaft. Shut down tractor leaving cutter in position of greatest distance. Securely block cutter in position. 8 Figure 2-3 H. Hold driveline sections parallel to each other and check for minimum 6 inches (15cm) overlap. Figure 2-4). If driveline has been marked for cutting, overlap will be the distance between two marks. If driveline has less than minimum overlap, do not use. Contact authorized Bush Hog dealer. Figure 2-4 Minimum Overlap NOTE If driveline is the correct length, omit the following steps “I” through “L” and proceed to step “M”. I. Clamp driveline in a well padded vice to prevent damage to the shield. Cut off shield where marked. (Figure 2-5) Figure 2-5 J. Using cut off section of shield as a guide, cut shaft the same amount. (Figure 2-6) Figure 2-6 K. Repeat steps “I” and “J” to other driveline section. L. Deburr ends of driveline sections and clean away all chips and filings. (Figure 2-7) Figure 2-7 M. Apply multi-purpose grease to inside of outer (female) driveline section. Assemble driveline and install on tractor and cutter. Pull on each driveline section to be sure yokes lock into place. Make certain driveline shielding is in place and in good condition. N. Adjust lower lift arm(s) to level cutter right to left. Refer to tractor operator's manual for instructions. NOTE After attaching driveline to tractor, attach driveline shield chains from both ends of driveline shielding to stationary locations. 9 SECTION III OPERATING INSTRUCTIONS 3-1 GENERAL SAFETY Only qualified people should operate this machine. Operator should wear hard hat, safety glasses and safety shoes. It is recommended that tractor be equipped with Rollover Protective Systems (ROPS) and a seat belt be used. Before beginning operation, clear work area of objects that may be picked up and thrown. Check for ditches, stumps, holes or other obstacles that could upset tractor or damage cutter. Always turn off tractor engine, set parking brake, and allow cutter blades to come to a complete stop before dismounting tractor. 3-2 ADJUSTING FOR WORK The cutter should be operated at the highest position which will give desired cutting results. This will help prevent the blades from striking the ground, reducing b...
