Overview

The Kubota B5100 is a small utility tractor made from 1978 to 1984. It's a 2WD model with a compact size, measuring 71.6 inches long, 36.2 inches wide, and 44.1 inches tall. This tractor is very light, weighing only 805 pounds, making it easy to move around small farms or gardens.

The B5100 has a Kubota Z500-A1 diesel engine with two cylinders. It's not very powerful, with just 12 horsepower, but it's enough for light tasks. The engine runs at a very high 3000 RPM and has a small displacement of 31 cubic inches. It has a 6-speed forward and 2-speed reverse transmission, which gives it good control at different speeds. The tractor has a three-point hitch at the back that can lift up to 310 pounds, which is below average for tractors. It also has a PTO (Power Take-Off) that can run at 540 or 1000 RPM, useful for powering attachments.
