This Kubota Workshop Manual is the mechanism and servicing reference for a wide range of Kubota tractors, from the compact B series through the L series and up to the M series, including popular models such as the B7800, L2800 and the M8200 and M9000 families. It runs 390 pages and follows Kubota's own construction and function layout.
The volume centers on the chassis and driveline: clutch, the transmission in its shuttle shift, dual speed, hydrostatic and power shift forms, rear and front axles, brakes, manual and power steering, the hydraulic system, the electrical system and the cabin air conditioning.
Because it explains how each system is built and how it works, an owner or independent mechanic can understand a fault before disassembling, then follow the servicing detail to put the machine right.
