Part of the Kubota Repair Manuals.
This Kubota Workshop Manual covers the RCK54-24B-EC, RCK60-24B-EC, RCK60-27B-EC, RC60-24BR, and RC60-27BR rotary mower decks. Across 56 pages it gives servicing personnel the mechanism, service, and maintenance information for this family of side and rear discharge mowers.
The manual is organized into General, Mechanism, and Servicing parts. You get mower identification, lubricants, tightening torques, and the maintenance check list, then the power transmission and lifting mechanism, and finally troubleshooting, servicing specifications, and checking, disassembling, and assembling procedures.
Owners and independent shops use it to work the deck with factory values, from mower blade screw torque and bevel gear backlash to blade lengths and cutting widths for each model. Both the cylinder-lift and 3-point hitch lift versions are covered.
