Common Issues & Fixes:

• Hydraulic leaks under heavy load: Caused by worn piston seals—use high-pressure rebuild kits

• Overheating: Dirty radiator or failing thermostat

• Transmission slipping: Hydrostatic pump wear or low fluid

• Steering drift: Caused by worn center articulation joints

Pro Tips:

• Grease articulation and pivot points frequently under heavy use

• Use loader-specific tires for maximum traction and durability

• Monitor hydraulic oil condition—foaming or discoloration signals internal wear

Serial Number Location:

Serial number plates are typically located on the loader’s frame under the operator platform or on the articulation joint housing.
