MAINTENANCE
HYDRAULIC SYSTEM
PUMP & MOTOR
The pump and motor is the heart of the hydraulic circuit and is vital to the performance of all Triumph mowers. Worn
pumps and motors should be replaced or repaired. It is recommended that most customers replace when this
occurs however, spare parts and seal repair kits are available for field repair if desired. ALWAYS DRAIN, CLEAN
AND REFILL THE TANK WITH CLEAN OIL when pump repairs are made.
NOTICE: To avoid possible damage to a new or rebuilt pump, run the tractor engine at very low RPM for about 5
minutes with all control levers in neutral position prior to placing in service.
