Part of the Kubota Repair Manuals.
This Kubota Workshop Manual covers the RCK48-15BX, RCK48-22BX, RCK54-15BX, RCK54-22BX, and RCK60B-22BX rotary mower decks for BX-series machines. It is a 46 page PDF you download and keep, organized into mechanism and servicing so you understand how the deck works before you take it apart.
You get safety information, terminology for every deck component, specifications with cutting width and blade spindle speed, and a general section with mower identification, lubricants, tightening torques, a maintenance check list, and setup and adjustment steps. The rotary mower section then details power transmission, the lifting mechanism, and the self-balancer system.
With it you can set cutting height, correct blade tip differences, service the gear box, adjust belts and pulleys, and torque the blade and pulley hardware to the factory figures.
