Locate tractor and loader on firm level ground.412. With bucket raised above ground, tilt bucket down approximately 30 degrees from level.413. Lower boom by retracting lift cylinders to lift tractor front end (tires can be off ground).414. Stop engine. Allow tractor front end to lower by relaxing ONLY lift cylinders with control lever. This will remove pressure on hitch pins (See Figure Asm-L-0002).415. Set parking brake. Rotate parking stands from storage position by removing linch pins and clevis pins. Reinstall clevis pins and linch pins when parking stands are in operation position (See Figure Asm-L-0001).416. Remove linch pins and 1” hitch pins from loader upright.417. Start tractor engine and release brakes. Retract bucket cylinders to allow parking stands to contact ground.418. Extend lift cylinders 6” to 8’ to rotate top of loader uprights forward out of the mount, allowing tractor to be pushed rearward. Retract bucket cylinders until lower loader upright pins clear mount pin saddles and front tires (See Figure Asm-...419. Move tractor rearward approximately 6”, being certain not to stretch hydraulic hoses.4110. Stop tractor engine and set parking brake. Relax lift cylinders and bucket cylinders by moving each control lever in both directions. Disconnect hydraulic hoses from tractor.4111. Start tractor engine and release brakes. Slowly back tractor out of loader.41Mounting Loader421. Slowly drive tractor into loader approximately 6” from loader mounts. Shut off tractor engine and set parking brake.422. Connect hydraulic hoses. Make sure couplers are clean before connecting together.423. Start engine and release parking brake. Make sure lift cylinders are extended 6” to 8”. Stroke bucket cylinders to raise or lower upright pin to clear each front mount pin saddle by approximately 1” (See Figure Asm-L-0001).424. Drive tractor forward until loader upright pins contact mount vertical stop surfaces just above the mount pin saddles (See Figure Asm-L-0001). Extend bucket cylinders to FULLY seat both loader upright pins into mount pin saddles and raise parking ...425. Stop engine. Allow tractor front end to lower by relaxing ONLY lift cylinders with control lever.426. Set parking brake. Insert two 1” hitch pins and linch pins.427. Remove linch pins and clevis pins from parking stands, rotate stands into storage position and secure with clevis pins and linch pins (See Figure Asm-L-0001).42Attaching Pin on Bucket431. Attach bucket to lift boom frame and cylinders with four 1” pins, use two 3/8 shoulder bolts and 3/8 lock nuts at upper pin (bucket cylinder). Use two 3/8 x 1.25 hex bolts, 3/8 jam nut, 3/8 flat washer and 3/8 lock nut at lower pin. Position bol...432. Install level indicator rod in level guide tube on right bucket cylinder. Sandwich level indicator rod angle between right inside bucket ear and cylinder rod end.433. Set bucket level on ground and adjust level guide tube along bucket cylinder until end of guide tube is flush with end of rod.43Assembling Quick Attach Device431. Quick attach device is pre-assembled at the factory.432. Unband the quick attach device and wood blocks. (Figure Asm-L-0012)43Installing Quick Attach Device441. Fasten quick attach device to lower boom arms and bucket tilt cylinders using 1” x 4-3/8” anti-rotation pins, 3/8” x 3/4” shoulder bolts, and 3/8” lock nuts (supplied with loader). Figure Asm-L-0014.442. Attach bucket leveling rod indicator (supplied with loader), to outside of right ear on quick attach as shown. Figure Asm-L-0014. Secure bucket leveling rod indicator with two 1/8” x 1” cotter pins (supplied with loader).441. Be sure both quick hitch pin levers are in the unlocked position, with the levers pointing up. Tilt the loader quick hitch forward, drive the loader into the attachment bracket and engage top of the quick hitch into the top of the attachment bracket.452. Raise the loader slightly and rotate the top of the quick hitch back toward the operator until the bottom of the attachment is seated firmly in the bottom of the quick hitch.453. Rotate the quick hitch pin levers down 90 degrees to the locked position. You should feel a firm resistance when locking the levers down. The tapered pins must extend through the slots in the bottom of the attachment bracket. The tapered side of t...454. Raise the loader and attachment to shoulder height. By standing at the side of the loader, inspect the connection between the quick hitch and attachment.455. On level ground, tilt the attachment down 90 degrees and lower it to the ground. Lower the loader further to slightly raise the front of the tractor of the tractor off the ground. Drive the tractor in reverse while the attachment is on the ground ...46OPERATION SECTION47BUSH HOG 1945 LOADER48OPERATION INSTRUCTIONS481.

Check fluid level of tractor hydraulic system before starting each day’s operation. If necessary, add hydraulic oil as recommended in your tractor operator’s manual.952. Daily, unless conditions justify more frequently, lubricate all twelve grease fittings; one at each end of lift boom arms and one at rod and base ends of each lift and bucket cylinder.953. After every ten hours of operation, check all hardware and tighten where required.954. Replace hoses immediately if they are damaged by a cut or scrape, extruded at the fittings or leaking. Hydraulic oil leaks should be repaired promptly to avoid loss of oil and serious personal injury from escaping oil.95Cylinder Service96Lift and Bucket Cylinder Disassembly961. Hold cylinder tube (13) stationary and pull wire ring (14) out through slot.962. Pull shaft (1), with all assembled parts, out of cylinder tube (13).963. Remove elastic locknut (12) from end of shaft and slide cylinder piston (10) and cylinder head (4) off shaft.964. Remove piston wear ring (11), piston seal (8), and o-ring (7) from outside grooves on piston(10).965. Remove wiper seal (2), rod seal (3) and wear ring (5) from inside of cylinder head and o-ring (7) with backup washer (6) from groove on outside of head.966. Clean all parts including cylinder tube, in a suitable cleaning solvent, then use air pressure to blow any dirt or excess solvent from all parts.967. Examine all parts for wear or damage and replace, if necessary.96Lift and Bucket Cylinder Reassembly971. Place rod seal (3) into groove inside cylinder head.972. Install wiper seal (2) with lip of seal facing out and flush with top of cylinder head (5). Install wear ring (4) inside other end of head (5).973. Place o-ring (7) with back-up washer (6) in groove on outside of head. Back-up washer must be on rod side.974. Remove sharp edges on outer edge of the threaded end of shaft (1). Lubricate wiper seal (2) and rod seal (3) in head and carefully slide head onto shaft.975. Place o-ring (10), piston seal (11) and piston wear ring (8) in grooves on outside of piston (9).976. Slide piston (9) onto threaded end of shaft and install lock nut (12). Tighten lock nut to 100 lbs.977. Lubricate piston wear ring (8) and piston seal (11) on piston, o-ring (7) and backup washer (6) on head and inside of cylinder tube (13), then carefully slide piston and head into cylinder tube (13).978. Insert wire retaining ring (14) into slot in cylinder tube (13). Apply pressure to wire ring to thread it into groove while turning cylinder head.979. Note: If cylinder has a countersunk hole, hook end of retaining wire into hole and turn cylinder head 1-1/2 turns to secure wire. End of hook may need to be ground to fit in countersunk hole.97Storage981. Store loader with attachment securely attached.982. Place dust caps on hydraulic quick couplers.983. Do not remove attachment from stored loader.994. Do not allow children to play on or around loader.99Proper Torque for Fasteners100TO THE OWNER/OPERATOR/DEALER105LIMITED WARRANTY104DISCLAIMER OF IMPLIED WARRANTIES & CONSEQUENTIAL DAMAGES104THIS LIMITED WARRANTY SHALL NOT APPLY:1041.
