- Dismounting Loader and Mounting Loader to Tractor
- Dismounting Loader
- 1. Locate tractor and loader on firm level ground.
- 2. Level and lower bucket to ground. Engage tractor brakes and shut off tractor engine. Move lift control lever back and forth several times to relieve pressure in lift cylinders.
- 3. Remove 3/4 lock nuts and washers which clamp hinges closed around mid mounting tubes on tractor.
- 4. Start tractor engine and release tractor brakes. Activate lift control lever to raise side frame up off midmounting assembly. Continue rotating loader side frames off midmounting tubes. Slowly back tractor out of loader while rotating loader side ...
- 5. Move lift and bucket control levers back and forth several times to relieve pressure on lift and bucket cylinders. Disconnect quick couplers between loader and tractor. Hang hoses over loader side frame upright for storage. Make sure male quick co...
- 6. Fasten bolts, washers and nuts onto hinge for storage.
- Preparing Stored Loader for Mounting
- 1. Slowly drive tractor up to loader until hoses will reach from loader to control valve couplers.
- 2. Make sure quick couplers are clean. Connect quick couplers between tractor and loader. Match color coded bands when connection couplers.
- 3. Start tractor engine and release tractor brakes. Operate lift control to extend lift cylinders until side frame uprights will clear front axle. Make sure counterweighted hinges swing fully open. Proceed to instruction 1 in “Mounting Procedure”...
- Mounting Loader
- 1. Slowly drive tractor up to loader until hoses will reach from loader to tractor. Engage tractor brakes and shut off tractor engine.
- 2. Connect quick couplers between tractor and loader, matching color coded bands.
- 3. Start tractor engine and release tractor brakes. Slowly drive tractor ahead while activating lift control lever to extend or retract lift cylinders, positioning tractor so hinges hook midmounting bracket tubes as loader side frame uprights rotate.
- 4. Put tractor in neutral. Retract lift cylinders bringing side frame channels up so front yoke tube contacts front mounting top flange. Move tractor ahead so front yoke tube engages in front mounting bracket channel and loader side frame uprights se...
- 5. Clamp hinge around midmounting tube using 3/ 4 washer and flex-lock nut.
- 6. Loop hoses through hose support bracket on front mounting bracket.
- 7. Loop one rubber tie strap around hoses and hook on yoke to keep tension on hoses. Secure hoses to loader right side frame using other rubber tie strap (Figure Asm-L-0033).
- Dismounting Loader
- Quick-Attach Round Bale Spear
- Attaching Quick Attach Buckets or Round Bale Spear
- 1. Locate tractor and attachment on firm level ground. Lower boom to rest on ground.
- 2. Extend bucket cylinders slightly, while raising boom to three to five inches of ground clearance. Making sure loader quick attach bar is parallel to attachment, drive tractor ahead very slowly toward attachment. Continue driving tractor forward, p...
- 3. Activate bucket rollback while moving tractor slightly ahead so quick attach bar catches underneath channel of attachment. Continue to roll attachment back completely so latch pins engage in bracket ears.
- 4. Activate lift cylinder to raise attachment and extend bucket cylinders to tilt attachment at a slight downward angle so quick attachment mechanism is visible. Visually inspect mechanism to verify pins are engaged in ears on back of attachment.
- Detaching Quick Attach Buckets or Round Bale Spear
- 1. Locate tractor and loader on firm level ground.
- 2. Lower boom arms until bucket or bale spear rests level on ground. Shut off tractor engine and engage tractor brakes.
- 3. Disengage latch pins by lifting handles and rotating them so pins and blocks provided on attachment ears.
- 4. Start tractor engine, release tractor brakes and extend bucket cylinders while slowly backing tractor away from bucket or bale spear, until quick-attach bar disengages from attachment channel.

- MAINTENANCE SECTION
- Lubrication Schedule
- Daily Maintenance
- 1. 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.
- 2. Daily (unless conditions justify more frequent greasing) 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.
- 3. After every ten hours of operation, check all hardware and tighten where required.
- 4. 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.
- Cylinder Service

- 6. 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.
- 7. Examine all parts for wear or damage and replace, if necessary.
- Lift and Bucket Cylinder Reassembly
- 1. Place rod seal (3) into groove inside cylinder head.
- 2. 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).
- 3. Place o-ring (7) with back-up washer (6) in groove on outside of head. Back-up washer must be on rod side.
- 4. 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.
- 5. Place o-ring (10), piston seal (11) and piston wear ring (8) in grooves on outside of piston (9).
