The Kubota B7001 is a popular 2-cylinder, 4WD compact tractor from the early 1980s (part of Kubota’s ‘B’ series). It was often a gray market import (originally sold in Japan), so official Kubota USA/Europe support is limited. The Work Shop Manual (WSM) is the official factory document for mechanics. It is not the same as the operator’s manual (basic controls) or parts catalog. kubota b7001 service manual
