Locate tractor and loader on firm level ground.392. With bucket raised above ground, tilt down approximately 30 degrees from level.393. Lower boom by retracting lift cylinders to lift tractor front end (tires can be off ground).394. Stop engine. Allow tractor front end to lower by relaxing ONLY lift cylinders with control lever. This will remove pressure on hitch pins (See Image395. Set parking brake. Rotate parking stands from storage position to operation position by removing linch pins and hitch pins. Reinstall hitch pin and linch pin when parking stands are in operation position. (See Figure Asm-L-0040).396. Remove linch pins and 1-1/4” hitch pins from loader upright.397. Start tractor engine and release brakes. Retract bucket cylinders to allow parking stands to contact ground.398. Extend lift cylinders 10” to 12” 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 and/or fenders...409. Move tractor rearward approximately 6”, being certain not to stretch hydraulic hoses.4010. 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.4011. Start tractor engine and release brakes. Slowly back tractor out of loader.40Mounting Loader401. Slowly drive tractor up to loader. Shut off tractor and apply brakes.402. Connect hydraulic hoses. Make sure couplers are clean before connecting together.403. Start engine and release parking brake. Make sure lift cylinders are extended 10” to 12”. Stroke bucket cylinders to raise or lower uprights for loader upright pin to clear each front mount pin saddle by approximately 1” (See Figure Asm-L-0003)404. Drive tractor forward until loader upright pins contact mount vertical stop surfaces just above the mount pin saddles (See Figure Asm-L-0003). Extend bucket cylinders to FULLY seat both loader upright pins into mount pin saddles and raise parking ...405. Stop engine. Allow tractor front end to lower by relaxing ONLY lift cylinders with control lever.406. Set parking brake. Insert two 1-1/4 x 7” pins and linch pins.407. Remove linch pins and hitch pins from parking stands, rotate stands into storage position and secure with hitch pins and linch pins.40Attaching Pin on Bucket41Mounting and Dismounting Attachment42Mounting Attachment to Loader421. Locate tractor and attachment on level ground. Lower boom to rest on the ground. Extend the bucket cylinders slightly, while raising the boom to provide three to five inches of ground clearance. Drive the tractor ahead slowly toward the attachment...422. While driving the tractor ahead slowly to maintain contact with the attachment, activate the lift cylinders to raise the loader until the quick attach engages under the attachment lip.423. Activate bucket cylinders to retract, continuing to roll the attachment back completely.424. Use instructions listed in MAINTENANCE SECTION of this manual to check all hose and tubing connections to insure no leaks are present.425. Start tractor, activate lift cylinders to raise attachment one or two feet off the ground and extend bucket cylinders to tilt attachment at a slight downward angle, so quick attachment latch pins are visible. Visually inspect the attachment mechan...42Detaching Quick Attach Device431. Locate tractor and loader can level ground.432. Lower boom arms until the attachment is level and resting on ground.433. Place tractor in neutral, set parking brake, shut off tractor engine and disengage quick attach device latch pins by moving handles to unlatch position (refer to Figure Asm-L-0039).434. Start tractor engine, release brake and extend bucket cylinders while slowly backing the tractor away from attachment, until quick attach disengages from attachment.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_B.442. Attach bucket leveling rod indicator (supplied with loader), to outside of right ear on quick attach as shown. Figure Asm-L-0014_B. Secure bucket leveling rod indicator with two 1/8” x 1” cotter pins (supplied with loader).44OPERATION SECTION47BUSH HOG 5145 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. After every eight hours of operation, 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.
