Part of the Kubota Repair Manuals.
This Kubota workshop manual covers the RCK54-32 and RCK60-32 rotary mower decks, the 54 inch and 60 inch cutting units built for Kubota tractors. Its 51 pages take you from safety information and specifications through the deck mechanism and into servicing.
You get mower identification, lubricant and tightening torque tables, and a mechanism section explaining the power transmission, lifting mechanism and blade layout. The servicing chapter adds troubleshooting, servicing specifications, and step by step checking, disassembly and assembly, including gear box backlash limits and blade screw torques.
For an owner or independent mechanic setting up, mounting or rebuilding one of these decks, this PDF download gives the factory figures and procedures in a searchable file you can read on any device or print for the workshop.
