Part of the Kubota Repair Manuals.
This is the Kubota factory workshop manual for the BX22 compact tractor together with its LA210 front loader and BT600 backhoe, publication 97897-12960, covering machines built from 2003 to 2005. The BX22 runs the D905-E-BX diesel engine.It is a full service manual split into engine, transaxle, front axle, steering, hydraulic system, and electrical system chapters, plus dedicated front loader and backhoe sections. You get specifications, troubleshooting charts, servicing clearances, tightening torques, and detailed disassembly and reassembly procedures for the whole machine.With it you can trace a hydraulic or power steering fault, service the hydrostatic transmission, set relief valve pressures, torque loader and backhoe hardware to factory values, and work through engine or electrical problems methodically. The manual is a downloadable PDF you can view on a phone, tablet, or computer, or print the pages you need for the workbench.

Kubota BX22, LA210, BT600 Common Problems This Manual Covers
Hydraulic hose leaks and hard access
BX owners report hoses that leak or fail and are awkward and costly to reach. The Hydraulic System section covers the circuit, control valve, and overload relief valve so you can trace and correct the leak.
Manual Section: 5.Hydraulic System p. 185Loss of power steering assist
Power steering can drop off after a hydraulic or o-ring problem in the steering circuit. The Steering section gives the relief valve operating pressure and servicing steps to diagnose it.
Manual Section: 4.Steering p. 173HST whines or feels weak
A whining or weak hydrostatic transmission, especially at low RPM, points to fluid condition or HST wear. The Transaxle section covers the traveling system and HST servicing.
Manual Section: 2.Transaxle p. 108Overheating under load
Overheating usually comes from clogged radiator fins, low coolant, or a loose fan belt. The Engine section covers the cooling system service and checks needed to clear it.
Manual Section: 1.Engine p. 51Hard starting or no-start
A battery that drains or a weak charging circuit shows up as hard or no starting. The Electrical System section covers the battery, charging, and starting circuits with the checks to make.
Manual Section: 6.Electrical System p. 216Weak loader lift
Slow or weak lift on the LA210 loader can trace to relief valve pressure or hydraulic wear. The Front Loader section gives the loader specifications and relief valve setting to verify.
Manual Section: 7.Front Loader p. 244Frequently Asked Questions
Which machines does this manual cover?
It covers the Kubota BX22 compact tractor built from 2003 to 2005, plus the LA210 front loader and the BT600 backhoe. The BX22 uses the D905-E-BX diesel engine, and the manual has dedicated loader and backhoe chapters.
What is the hydraulic pump relief valve pressure?
The Hydraulic System section gives the pump relief valve setting pressure of 12.3 to 12.7 MPa (1778 to 1849 psi) for the BX22, useful when checking weak hydraulic performance. p. 185
Does it list loader bolt torque values?
Yes. The Front Loader section covers torque values such as 33.7 N·m for the control valve mounting bolt and 170 to 183 N·m for the boom and bucket cylinder piston nuts on the LA210. p. 244
