Three machines, one book: the BX22 compact tractor, LA210 loader, and BT600 backhoe, documented across 320 pages under OEM #97897-12960. Coverage runs through engine, transaxle, front axle, steering, hydraulics, and the electrical system, plus both attachments. Six pages of hydraulic circuit diagrams map the BX22 main system, LA210 loader, and BT600 backhoe, alongside wiring diagrams showing safety switch logic and charging layouts. The procedures section spans 150 pages, backed by 50 exploded views, 9 pages of torque tables, and maintenance schedules from the 50-hour break-in out to every 3,000-hour service. Set the BX22 hydraulic pump relief valve to 12.3 to 12.7 MPa (1778 to 1849 psi); torque the LA210 control valve mounting bolts to 33.7 N·m (25 ft-lbs). With the machine down and the clock running, download it, search any spec by keyword, and get back to digging.

Kubota BX22, LA210, BT600 Common Problems This Manual Covers
Kubota BX22 hydraulic hose leaking at fitting or power steering suddenly stops working p. 177
Inspect every hose fitting and connection for seepage before starting. On the steering circuit, torque the power steering hose mounting nuts to 28.4 to 30.0 N·m (20.9 to 22.1 ft-lbs) per page 176. Replace any cracked or weeping hoses. If steering stays heavy or erratic after the repair, confirm relief valve pressure sits at 9.30 to 9.79 MPa (1348 to 1419 psi) per page 177.
Manual Section: 4.SteeringHST whines at low RPM or tractor barely moves under load in either direction p. 120
Confirm the hydraulic fluid level first, then look over the HST for external leaks around the case and fittings. The transmission oil strainer should be clean; its service interval is every 300 hours per page 32. Run the engine at full throttle before diagnosing weak drive, since HST output drops sharply at low RPM. If noise and vibration persist, follow the troubleshooting procedures starting on page 120.
Manual Section: 2.TransaxleEngine temperature climbs into the red during loader work or extended idling p. 58
Clean the radiator fins with compressed air, working from the engine side out. Fan belt deflection should measure 7 to 9 mm (0.28 to 0.35 in.) under 98 N (22 lbs) of force per page 58. If it still overheats, test the thermostat: it should begin opening at 80.5 to 83.5 °C (176.9 to 182.3 °F) and reach full open by 95 °C.
Manual Section: 1.EngineEngine won't start or turns over slowly, battery reads low after sitting overnight p. 228
Measure battery voltage with the engine off; it must read more than 12 V per page 228. With a healthy battery, inspect the air cleaner element and clean it every 50 hours per page 28. Confirm the fuel filter has been replaced at 500-hour intervals. If cranking stays slow, bleed the fuel system for trapped air before pulling the injectors.
Manual Section: 6.Electrical SystemFront loader boom rises slowly or stalls before reaching maximum lift height p. 257
Top up the hydraulic fluid and replace the filter every 200 hours per page 24. Verify loader relief valve pressure at 133.5 to 140 kgf/cm² (1900 to 2000 psi) on page 257; low pressure points to an internal valve bypass, not a failed pump. Look over each hose fitting for seepage and torque any loose connections before ordering parts.
Manual Section: 7.Front LoaderFrequently Asked Questions
How do I reset the PTO or safety interlock on a Kubota BX22?
To check the PTO safety interlock, put the range gear shift lever in 'NEUTRAL' and the PTO clutch lever in 'ON'; the engine should not crank. For the range linkage test, shift to 'LOW' or 'HIGH'; again, the engine should not crank. Both checks belong to the 50-hour maintenance and confirm the safety switches work.
What do error codes or warning lights mean on a Kubota BX22?
The BX22 signals status through indicator lamps. The Pre-heat Indicator Lamp lights when the key switch is in the "Pre-heat" position, the Charge Lamp flags a charging system problem, and the Oil Pressure Lamp comes on when engine oil pressure runs low.
What are the torque specs for Kubota BX22 loader or backhoe bolts?
On the Front Loader, the boom cylinder piston mounting nut takes 170 to 183 N·m (17.3 to 18.6 kgf·m, 125 to 135 ft-lbs), and the bucket cylinder piston mounting nut takes the same 170 to 183 N·m (17.3 to 18.6 kgf·m, 125 to 135 ft-lbs). On the Backhoe, the cylinder piston mounting nut for boom, stabilizer, dipperstick, and bucket takes 157 to 196 N·m (16.0 to 20.0 kgf·m, 116 to 145 ft-lbs).
How do I bleed air from the hydraulics on a Kubota BX22?
No general procedure exists in the manual for bleeding air from the whole hydraulic system. For the steering circuit, though, 'Bleed' appears as the fix for 'Insufficient bleeding' in the troubleshooting section.
How will I receive this Kubota BX22, LA210, BT600 Workshop Manual?
Immediate download of the complete 320-page searchable Workshop Manual. Open it on any device, from the laptop at your desk to the phone in the field.
Can I print this Kubota BX22, LA210, BT600 manual?
Yes. The PDF carries no DRM restrictions, so you can print any page or section you need for the shop. It works with any standard printer.
Are hydraulic system diagrams in this Kubota BX22, LA210, BT600 Workshop Manual?
Yes. Complete hydraulic schematics are included, with flow diagrams, valve configurations, and pressure specifications.
