One operator manual, three loaders. This 39-page reference carries separate lift capacity tables and rollback force charts for the LA513, LA723, and LA853, so you read the numbers for your machine and not a close cousin. Nineteen pages of operating procedure cover bucket filling, loading from a bank, backfilling, valve lock, and moving large heavy objects without tipping. Safety notes break into three tiers, Danger, Warning, and Caution, marking which shortcuts cost you. Grease every fitting at 10-hour intervals; on reinstall, torque the M16 front axle frame bolts to 23 kgf-m (166 ft-lbs). When the machine is down you want exact figures, not forum guesses. Bookmarks let you jump to any section from the seat, and the download is yours the moment you pay.

Kubota LA513, LA723, LA853 Common Problems This Manual Covers
Loader or bucket moves the opposite direction from light joystick input p. 18
Test boom and bucket movement right after installation, following page 18. Inspect the quick couplers and confirm hose routing, then swap any reversed connections. Start the engine at idle and verify correct movement before working up to the 18.1 MPa (2630 psi) maximum hydraulic pressure.
Manual Section: Pre-Operation CheckExcessive vibration or chatter during loader operation with noticeable looseness at the front axle frame brackets p. 32
Inspect the main frame M16 bolts and nuts daily, and torque any loose hardware to 23 kgf-m (166 ft-lbs) per page 32. Grease the control lever linkages and fittings every 10 hours to head off wear and chatter.
Manual Section: MaintenanceBoom or bucket drifts, responds slowly, or will not lift consistently after initial installation or maintenance p. 18
Check the hydraulic system for trapped air and cycle the cylinders to bleed it. Confirm rear tire inflation sits at 140 kPa (20 psi) per page 18 for tractor stability, then inspect all loader hoses and fittings for external leaks.
Manual Section: Pre-Operation CheckVisible hydraulic fluid leaks forming at the hose couplers and fittings along the loader boom arms p. 10
Clean the affected couplers and inspect the hoses for cuts or heavy wear. Replace damaged lines right away to stop dangerous fluid release. Cross-check the maximum hydraulic pressure on page 10; the system should stay under 18.1 MPa (2630 psi).
Manual Section: Servicing Of LoaderFrequently Asked Questions
How do I reset the Kubota LA513/LA723/LA853 loader after hydraulic lock or pressure build-up?
Lower the bucket to the ground, stop the engine, then relieve all hydraulic pressure by moving the control lever in every direction. If the boom or bucket still works backward, recheck and correct each hydraulic connection. After any hydraulic work, bleed the system by raising and lowering the boom and bucket repeatedly until it responds properly.
What are the torque specs for Kubota LA513/LA723/LA853 loader mounting bolts and hydraulic fittings?
Re-tighten the M16 bolts and nuts on the main frames (front axle frame and rear brackets) to 23 kgf-m (166 ft-lbs) after the first 20 to 30 hours. The general chart for metric cap screws lists M16 bolts (property class 8.8) at 196 to 225 N-m (20.0 to 23.0 kgf-m, 145 to 166 ft-lbs). The manual says to check hydraulic fittings for tightness but gives no torque figure for them.
How do I safely remove and reinstall the Kubota LA513/LA723/LA853 front loader?
Removal runs 15 steps starting on page 34: raise the boom, stop the engine, pull the spring pins and mounting pins, disconnect the hydraulic hoses, and back the tractor away. Reinstallation is a 12-step sequence on page 37, driving the tractor between the side frames, connecting hoses, engaging the guide plates, reinstalling mounting pins, and securing the stands.
How do I bleed air from the hydraulic system on a Kubota LA513/LA723/LA853 loader?
Raise and lower the boom and bucket repeatedly until all air clears the system and it responds properly. Keep the control lever out of the float position while the bucket is off the ground.
How to reset Kubota LA513 loader hydraulic pressure
Lower the bucket to the ground, stop the engine, then relieve all hydraulic pressure by moving the control lever through every direction. Cycling the lever this way bleeds off whatever pressure is still trapped in the system.
What format is this Kubota LA513, LA723, LA853 manual in?
Immediate download of the complete 39-page searchable Operator Manual. Read it on any device, whether that's the laptop at your desk or your phone out in the field.
Can I print this Kubota LA513, LA723, LA853 manual?
Yes. Print as many copies as you want, with no restrictions. Plenty of mechanics print just the section they need and carry it to the shop floor.
