Overview
The Kubota B1902 is a Japanese-built sub-compact utility tractor manufactured between 1981 and 1986, offering versatility in both two-wheel and four-wheel drive configurations. Powered by an 18.7 hp three-cylinder diesel engine, this model features a 12-speed unsynchronized gear transmission and a 540 RPM rear PTO for reliable farm performance.
Ideal Applications
Confined Space Operations:
With a slim width of 42.3 inches and a 57.3-inch wheelbase, this sub-compact tractor is engineered to navigate narrow passages and tight workspaces where larger farm equipment cannot fit.
Implements and Attachments:
The integrated 540 RPM rear PTO and 12 forward gears allow the operator to manage a variety of tasks requiring different speeds and powered rear-mounted tools.
Variable Terrain Tasks:
The availability of a 4WD variant (B1902DT) with 9.5 inches of ground clearance and wet disc brakes provides the necessary mechanical setup for handling diverse ground conditions.
