Kubota RC72-29A Common Problems This Manual Covers
Deck will not lift, lower, or stay attached
Trouble raising, lowering, or hooking up the deck often traces to a worn yoke or drive coupling at the tractor connection. The Universal Joint section lists the yokes, joint, and pins used in that hookup.
Manual Section: Universal Joint p. 4Weak drive or gearbox noise
Loss of power to the blades points to the gear box, its pinion shaft, bevel gears, or bearings. The Gear Box/Center Pulley section identifies the internal gears, bearings, and shims to inspect.
Manual Section: Gear Box/Center Pulley p. 6Vibration or spindle noise
Worn bearings or a damaged holder cause vibration and noise from the spindle during mowing. The Pulley Holder section lists the holder, bearings, seals, and boss for that assembly.
Manual Section: Pulley Holder p. 8Uneven cut, scalping, or streaking
Dull or worn blades and incorrect blade installation are common causes of stepped or streaked cutting. The Blade/Side Pulley section lists the blades, retainers, and side pulley components to check.
Manual Section: Blade/Side Pulley p. 10Belt slips or squeals
A worn belt or binding idler causes slipping and squealing after short use. The Tension Pulley section covers the belt, tension shaft, arm, pulley, and spring that maintain drive tension.
Manual Section: Tension Pulley p. 12Clogging or poor discharge
Material buildup under the deck follows a worn discharge deflector or damaged anti-scalp roller. The Roller/Discharge Deflector section lists the rollers, chute cover, stopper, and pins for that assembly.
Manual Section: Roller/Discharge Deflector p. 20Frequently Asked Questions
