Kubota RCK54-32, RCK60-32 Common Problems This Manual Covers
Uneven cut or poor leveling
A deck that scalps or leaves ridges is usually out of level or set up wrong on the tractor. The General section covers mower identification, setup and the check and maintenance steps for getting the deck level.
Manual Section: General p. 13Gear box noise or backlash
Whine or knock from the gear box points to worn bevel gears or excessive backlash. The Servicing section lists the factory backlash specification and allowable limit so you can measure and correct it.
Manual Section: Servicing p. 39Blade vibration or worn blades
Vibration or a rough finish often comes from worn, bent or unbalanced blades. The Mechanism section describes the center and outer blade layout so you can inspect and replace them correctly.
Manual Section: Mechanism p. 36Loose or misaligned mounting linkage
A deck that sits crooked or shifts under use usually has loose brackets or misadjusted links. The General section covers mounting to the tractor and setting up the links with the correct tightening torques.
Manual Section: General p. 13Blade spindle troubleshooting
A spindle that binds or runs rough needs inspection against the factory figures. The Servicing section provides troubleshooting and the checking, disassembling and assembling procedures for the blade spindle.
