This is the operator manual for the Kubota B1550HST and B1750HST compact tractors, including the HSE two wheel drive and HSD four wheel drive versions, powered by the Kubota D850-5B and D950-5B diesel engines. It is a 60 page PDF with a searchable text layer, covering models built from 1990 to 1997.
The manual covers safe operation, full specifications, implement limitations, the instrument panel and controls, the three point hitch, wheels and ballast, and day to day operating instructions. A detailed check and maintenance section handles fuel, engine oil, transmission fluid, the front axle, radiator, air cleaner, and battery, followed by adjustments and a troubleshooting chart.
Owners use it to run the tractor safely, follow the correct service intervals, set wheel nut torque and belt tension to spec, and work through engine, tractor, and battery troubleshooting when something goes wrong.

Kubota B1550–B1750 Series Common Problems This Manual Covers
Hard starting, smoke, then power loss
A clogged fuel filter, air in the fuel lines, or contaminated fuel causes hard starting, heavy smoke, and stalling under load. The troubleshooting chart walks through the engine faults and their likely causes.
Manual Section: Troubleshooting p. 48Weak or sluggish hydraulics and HST
Overdue transmission and hydraulic oil or a clogged filter leaves the HST drive and three point hitch feeling weak. The maintenance schedule sets the correct service intervals to keep them strong.
Manual Section: Maintenance p. 34Overheating and clogged radiator screen
Grass, dust, and debris pack the radiator screen and fins and drive coolant temperature up during mowing. The check and maintenance section covers cleaning the screen and servicing the cooling system.
Manual Section: Check and Maintenance p. 36Uneven or spongy brake pedals
Excessive free travel or uneven brake pedals point to needed adjustment or worn linkage. The adjustments section covers setting the brake pedals correctly.
Manual Section: Adjustments p. 46Loose wheel nuts
Wheel nuts that back off cause wobble and stud damage if not retorqued. The wheels and ballast section gives the torque values, 72 to 123 ft-lbs at the rear and 57 to 67 ft-lbs at the front.
Manual Section: Wheels, Tires and Ballast p. 27Slipping fan belt or charging issue
A loose or worn fan drive belt causes overheating and weak charging. The adjustments section sets the belt deflection to 10 mm under the specified pressure.
Manual Section: Adjustments p. 46Frequently Asked Questions
