Kubota LA525 Common Problems This Manual Covers
Loader lifts slowly or will not lift
If the loader moves sluggishly or will not lift, the cause is usually low or contaminated tractor hydraulic fluid, a clogged filter, or air trapped in the system. The Pre-Operation Check section covers checking transmission fluid and removing air from the hydraulic system.
Manual Section: Pre-Operation Check p. 19Mounting hardware works loose
The loader frame and brackets settle during the first hours of use, so the mounting bolts and nuts can loosen. The Maintenance section covers re-tightening the hardware and the main frame M16 bolt torque of 226 N-m.
Manual Section: Maintenance p. 32Stiff controls or pivot wear
Skipped lubrication leaves the loader pivots and control linkage stiff and prone to wear. The Maintenance section lists the grease fittings and the every 10 hours lubrication interval.
Manual Section: Maintenance p. 32Unsafe mounting or dismounting
Injuries happen when operators skip steps getting on or off, or leave the bucket raised on soft ground. The Operating the Loader section covers safe filling, lifting, carrying, and lowering, including float control and the valve lock.
Manual Section: Operating the Loader p. 22Trouble removing the loader
Taking the loader off the tractor can go wrong if the stands and pins are not handled in order. The Removing the Loader section gives the step by step procedure for lowering onto the stands and pulling the mounting pins.
Manual Section: Removing the Loader p. 35Trouble reinstalling the loader
Refitting the loader requires lining up the side frames and routing the hoses correctly. The Reinstalling the Loader section walks through driving the tractor into the frames and reconnecting the hydraulics.
