Part of the Kubota Repair Manuals.
This is the factory Kubota service manual for the BX24 compact tractor and its matched attachments, covering the BX24, the RCK54(P)-23BX and RCK60B-23BX mid mount mowers, the LA240 front loader, and the BT601 backhoe. It runs 437 pages and is built around the D902-E2-BX-2 diesel engine.
The manual is organized into nine sections: general service data, engine, transaxle, front axle, steering, hydraulics, mower, loader, and backhoe. You get servicing specifications, tightening torques, troubleshooting tables, and detailed disassembly and assembly procedures, including mounting and dismounting the LA240 loader and BT601 backhoe. Whether you are diagnosing weak hydraulics, restoring HST performance, servicing the mower deck, or rebuilding safety switches and the charging system, this PDF gives you the factory level detail an operator manual leaves out.
