Part of the Kubota Parts Manuals.
This is the Kubota factory parts catalog for the RCK54-24B mid-mount mower deck, the 54 inch deck fitted to Kubota compact tractors. Its 29 pages present exploded diagrams with reference numbers, Kubota part numbers, quantities, and serial ranges so you can pin down the right component before you buy.The catalog walks through every subassembly on the deck: the universal joint driveline, the bevel gear case, the pulley holder and spindle, the blades, the tension pulley and drive belt, the mower deck shell, the front gauge wheels and rear wheel, the linkage, the discharge cover, and the lift linkage and lift arm that raise and lower the deck.It is built for parts identification rather than step by step repair, which makes it the fast way to order blades, spindle bearings, belts, and gearbox parts without guessing between similar Kubota deck numbers.

Kubota RCK54-24B Common Problems This Manual Covers
Deck belt breaks or comes off
The deck belt shredding or throwing off is a common RCK54-24B complaint. A worn belt, a misrouted belt, a crooked idler, or debris around the pulleys are typical causes, all shown in the tension pulley diagram.
Manual Section: Tension Pulley p. 12Uneven cut, streaks, or scalping
Streaks, stingers, or a scalped lawn usually mean dull or bent blades, or the wrong blade fitted. This section identifies the blades and spindle so you can order correct replacements.
Manual Section: Blade p. 10Spindle noise and vibration
Excessive noise or vibration from the deck points to worn spindle bearings or a damaged spindle. The pulley holder diagram lists the bearings and seals needed for a rebuild.
Manual Section: Pulley Holder p. 8Gearbox needs service or fails early
The deck gearbox can wear or fail from low or degraded oil and missed lubrication. This section breaks down the case, pinion shaft, gear kit, shims, and seals.
Manual Section: Bevel Gear Case p. 6Poor cut in thick grass
Underpowered performance in heavy grass often comes from a clogged deck or airflow restriction rather than the engine. The mower deck section identifies the shell and covers for cleaning and repair.
Manual Section: Mower Deck p. 14Gauge wheel wear or wrong height
Worn gauge wheels or bushings let the deck scalp or ride unevenly. This diagram covers the gauge wheels, bushings, collars, and holders that set deck height.
Manual Section: Front Gauge Wheel p. 16Frequently Asked Questions
