Part of the Kubota Repair Manuals.
This is the Kubota BX1800 and BX2200 Workshop Manual, a 293 page PDF covering both sub-compact tractors and their D722-E-BX and D905-E-BX diesel engines. It opens with specifications, travelling speed, and dimensions, then works through the general section, engine, transaxle, front axle, steering, hydraulic system, and electrical system.
Each system is broken into mechanism and servicing, so you can learn how a part works before troubleshooting, disassembling, and reassembling it. That makes it usable for no-start diagnosis, cooling and hydraulic problems, transaxle work, and full electrical tracing with the wiring diagram.
Reference values include PTO power of 10.2 kW on the BX1800 and 12.4 kW on the BX2200, front wheel mounting screw torque of 122 to 146 N-m, and a hydraulic relief valve setting of 12.3 to 12.7 MPa. Instant PDF download that prints cleanly for bench use.
