Kubota FL850 Common Problems This Manual Covers
Broken or busted yoke
Forum users report the yoke at the tiller connection breaking under load, with replacement parts hard to source and costly. The Joint section shows the universal joint and yoke parts with their Kubota numbers.
Manual Section: Joint p. 17Bent or damaged rear cover
Impacts and rough handling can bend the rear cover or damage its hinge, a repair owners of used units often face. The Rotary Cover section lists the rear cover, hinge, and related hardware.
Manual Section: Rotary Cover p. 13Worn chain or sprockets
The chain and sprockets in the drive are inspected wear items on aging tillers and can stretch or wear with use. The Chain Case section identifies the chain, sprockets, and seals for replacement.
Manual Section: Chain Case p. 8Gear case oil seal leaks
Worn oil seals in the gear case let lubricant weep and can lead to bearing damage if ignored. The Gear Case section covers the oil seals, bearings, and bevel gears with part numbers.
Manual Section: Gear Case p. 4Rust and corrosion on the underside
Long storage and moisture leave rust on the side frames and support, common on used FL850 units even when the gears are sound. The Rotary Support section lists the side frame, supports, and covers.
Manual Section: Rotary Support p. 6Worn blade shaft or blades
The blades and blade shaft wear with rocky or heavy soil and eventually need replacing to till evenly. The Blade Shaft section shows the shaft, bushings, and left and right blades.
Manual Section: Blade Shaft p. 11Frequently Asked Questions
