Part of the Kubota Operator Manuals.
This is the operator's manual for the Kubota LA514, LA724, and LA854 front loaders, the factory book that covers mounting, operating, and maintaining these loaders on a suitable tractor. It is written for owners and operators who want to run the loader safely and keep it serviced.Inside you get the full loader, bucket, dimensional, and operational specifications, safe operating practices, pre-operation setup including rear ballast and bleeding air from the hydraulics, and step-by-step loader operation from filling and lifting to dumping and backfilling. It also covers attachments, the pallet fork, maintenance, and removing, storing, and reinstalling the loader.Use it to set the loader up correctly, work it safely, torque the main-frame bolts to spec, grease the pivot points, and take the loader on and off the tractor without damage. Delivered as a downloadable, printable PDF.

Kubota LA514, LA724, LA854 Common Problems This Manual Covers
Loader catches near float or down position
Operators report the loader locking up or hesitating as it approaches the float or down position, often a sticky control valve or spool. The operating section covers float control and correct lever movement to help isolate the behavior.
Manual Section: Operating The Loader p. 20Loader raises slowly or feels weak
Slow or weak lifting usually points to low hydraulic oil, air trapped in the system, or restricted flow. The pre-operation section explains removing air from the hydraulic system and setting up the remote control connections.
Manual Section: Pre-Operation Check p. 15Instability or tip-over risk
Running the loader without enough rear ballast or turning too fast creates a real tip-over hazard. The safe operation section covers the precautions, ballast, and slow, controlled handling these loaders require.
Manual Section: Safe Operation p. 4Loose main frame mounting bolts
Main frame bolts that loosen over time cause play and stress cracks if left unchecked. The maintenance section gives the M16 main frame bolt torque of 226 N-m and the recommended re-tightening checks.
Manual Section: Maintenance p. 32Trapped pressure when detaching
Difficulty detaching implements or a loader that resists coming off is often residual hydraulic pressure. The dismounting section shows the correct sequence for detaching implements and relieving the hydraulics.
Manual Section: Dismounting The Loader p. 29Worn pivot and mounting pins
Loose, dry pivot and mounting pins lead to slop and rapid bushing wear. The removal section identifies the boom, stands, spring pins, and mounting pins so you can inspect and replace worn hardware.
Manual Section: Removing The Loader p. 35Frequently Asked Questions
