Part of the Kubota Repair Manuals.
This is the Kubota Workshop Manual for the BX24 tractor and its matched attachments: the LA240 front loader, the BT601 backhoe, and the RCK54, RCK54P, and RCK60B rotary mowers. It is a 421 page PDF (OEM number 97897-18200) built around the D902-E2-BX-2 diesel engine, covering the whole tractor plus every implement in one document.Sections run through the engine, transaxle, front axle, steering, hydraulic system, and electrical system, then continue into the rotary mower, front loader, and backhoe. Each is split into general, mechanism, and servicing so you can understand a system before troubleshooting, disassembling, and reassembling it.Use it to diagnose no-start and shutdown faults, weak hydraulics, and mower or loader problems, and to set fasteners such as the front wheel screws to 149.2 to 179.0 N-m. Instant PDF download, print the pages you need.

Kubota BX24 Package Common Problems This Manual Covers
Engine cranks but will not shut off
The engine keeps running with the key off, or only stops when the stop lever is pushed by hand, typically a fuel shutoff solenoid, fuse, or wiring fault. The electrical section covers the stop solenoid and related circuits.
Manual Section: 6 Electrical System p. 259Intermittent no-start condition
The tractor will not start after sitting or starts only sometimes, often a weak battery, corroded wiring, blown fuse, or a failed safety switch. The electrical section lists the safety switch contacts and battery checks.
Manual Section: 6 Electrical System p. 259Loss of power or stalling
Rough running, stalling, or an inability to stay running usually traces to contaminated fuel, a clogged filter, or air in the fuel system. The engine section covers the fuel system and its service.
Manual Section: 1 Engine p. 60Weak or slow hydraulics
The loader or backhoe moves slowly and implements hesitate under load, pointing to low fluid, a clogged filter, aerated oil, or pump and valve wear. The hydraulic system section covers the pump, control valve, and relief valve.
Manual Section: 5 Hydraulic System p. 228Engine overheats during work
Coolant temperature climbs during mowing, loader, or backhoe work, commonly from low coolant, dirty radiator fins, or a loose fan belt. The engine section covers the cooling system and its checks.
Manual Section: 1 Engine p. 60Mower deck service and blade torque
The RCK54, RCK54P, and RCK60B decks need blade and spindle hardware set correctly during service. The rotary mower section gives the procedures and torques, including the mower blade screw at 102.9 to 117.7 N-m.
Manual Section: 7 Rotary Mower p. 3074WD hard to disengage
Front wheel drive can bind and resist disengaging, especially under load. The transaxle section covers the front wheel drive section so you can inspect and service the mechanism.
Manual Section: 2 Transaxle p. 125Frequently Asked Questions
