This is the Kubota B1700, B2100, and B2400 shop manual, a 454 page workshop and service manual covering the standard, HSD, D, HSDB, and E variants of these compact tractors, including their D905, D1005, and D1105 diesel engines. Unlike a parts catalog, this book gives the actual repair procedures.It is organized into sections for the engine, clutch, transmission (with the Bi-Speed Turn supplement), rear axle, brakes, front axle, steering, hydraulics, and electrical system, plus mower and enhanced model supplements. You get specifications, torque values, clearances, disassembly and reassembly steps, and troubleshooting.Use it to set cylinder head and connecting rod torque, check valve clearance, service the hydrostatic transmission and 3-point hydraulics, diagnose no-start faults, and adjust brakes and steering. Delivered as a downloadable, printable PDF.

Kubota B1700–B2400 Series Common Problems This Manual Covers
Tractor loses drive in both directions
A hydrostatic tractor that will not move or feels weak after fluid service often has low or contaminated oil, a clogged suction screen, or charge pump wear. The Transmission section covers HST service.
Manual Section: Sect 3 Transmission p. 1403-point hitch raises slowly or not at all
A hitch that lifts slowly, jerks, or will not raise usually points to low fluid, a worn pump, a stuck relief valve, or internal cylinder leakage. The Hydraulic section covers the pump, valves, and lift circuit.
Manual Section: Sect 8 Hydraulic p. 306No crank or no start
A no-crank condition often traces to the safety switches, battery cables, starter, or the fuel cutoff solenoid not receiving power. The Electrical section covers wiring, the starter, and solenoid testing.
Manual Section: Sect 9 Electrical p. 332Weak or contaminated brakes
Brakes that stop poorly or act unevenly are often caused by worn discs or contamination from leaking axle seals. The Brakes section gives service specs and procedures for the brake assembly.
Manual Section: Sect 5 Brakes p. 250Front-end play or toe-in issues
Steering play or toe-in problems develop after loader work or rough terrain, and 4WD front axles can develop backlash. The Front Axle section covers backlash checks and alignment.
Manual Section: Sect 6 Front Axle p. 264Overheating or power loss under load
Overheating and loss of power under load often come from a plugged radiator, restricted fuel supply, or engine wear. The Engine section provides the specs and procedures to diagnose and rebuild.
Manual Section: Sect 1 Engine p. 54Clutch or pedal free play out of adjustment
A dragging or slipping clutch usually needs pedal free-play adjustment or a worn dry plate replaced. The Clutch section covers adjustment and overhaul.
Manual Section: Sect 2 Clutch p. 124Frequently Asked Questions
