Part of the Kubota Repair Manuals.
This Kubota Workshop Manual covers the RC72-38 rotary mower, the 72 inch mid-mount belly deck, publication number 97897-17150. It is a compact 40 page factory manual with a searchable text layer and bookmarks.
It opens with safety, deck terminology, and specifications: a 1826 mm cutting width, three blades, a blade spindle speed of 2980 rpm, and an approximate weight of 210 kg. From there it covers mounting the deck to a suitable tractor, the maintenance schedule, the power transmission and lifting mechanism, and the servicing chapters with troubleshooting, servicing specifications, and tightening torques.
Use it to set the deck up and level it, adjust the linkage, service the gearbox and spindle, check bevel gear backlash, and torque the blade, pulley, and gearbox hardware to spec. It is delivered as a downloadable PDF you can search, print, or keep on a phone or tablet in the shop.
