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.

Kubota RC72-38 Common Problems This Manual Covers
Uneven cut or uncut strips
A stepped cut or missed strip usually comes from deck mis-leveling or an incorrect setup. The Setting Up Mower section covers deck mounting, leveling, and the clearance settings that square the deck to the ground.
Manual Section: Setting Up Mower p. 19Deck vibration and noise
Vibration or rattling often means worn spindle bearings or excess bevel gear backlash in the gearbox. The Servicing Specifications section lists the backlash factory spec and allowable limit for checking those parts.
Manual Section: Servicing Specifications p. 30Belt slipping or burning
A slipping or scorched belt points to worn pulleys, misalignment, or a tired belt. The Power Transmission section explains the drive layout so you can inspect the belt path and pulleys.
Manual Section: Power Transmission p. 26Blades will not engage
If the blades fail to spin up, the fault is usually in the drive path, belt, or engagement components. The Troubleshooting section walks the likely causes for the deck drive.
Manual Section: Troubleshooting p. 29Burning smell or seized spindle
A hot or burning smell from the deck can mean seized bearings, belt friction, or packed debris. The checking and servicing procedures cover spindle and gearbox inspection and rebuild.
Manual Section: Checking, Disassembling and Servicing p. 32Loose blade or pulley hardware
Loose blade bolts or pulley nuts cause vibration and can damage the deck. The Tightening Torques section gives the blade screw and outer pulley nut torques to fit them correctly.
Manual Section: Tightening Torques p. 31Frequently Asked Questions
