This is the factory operator manual for the Kubota B1550 and B1750 compact diesel tractors, covering the B1550E and B1750E in 2WD and the B1550D and B1750D in 4WD. These machines run Kubota's D850-5B and D950-5B diesel engines, and this 55 page book is the owner's guide to running and maintaining them.
Inside you get safe operation practices, full specification tables for each model, instrument and control layouts, three-point hitch and wheel setup, and the maintenance schedule with fluid and service intervals. A troubleshooting section and wiring diagrams round it out.
It is written for the operator, so it focuses on day to day running, checks, adjustments, and light service rather than full engine or transmission teardown.
Complete the set for your B1550–B1750 Series
