Last Updated: September 2024

Overview

The Kubota B40 is a small but mighty utility tractor that was made from 1988 to 1992. It's a sub-compact model, which means it's perfect for working in tight spaces. This tractor has four-wheel drive, so it can handle tough terrain.

The B40 is powered by a Kubota D850 engine. This engine is diesel-fueled and has three cylinders. It's liquid-cooled, which helps keep it running smoothly. The engine puts out 14 horsepower, which is on the lower end for tractors but good for its size. It has a gear transmission with 6 forward gears and 2 reverse gears, giving the driver good control. The tractor also has a PTO (Power Take-Off) that spins at 540 rpm, useful for running attachments.

This Kubota model is compact, measuring 84.7 inches long, 41.5 inches wide, and 49 inches tall. It weighs 1,213 pounds, making it one of the lighter tractors out there. The B40 has an open operator station with a two-post roll-over protection system (ROPS) for safety. It starts with an electric starter, making it easy to get going. With its small size and useful features, the Kubota B40 is a handy tractor for small farms and properties.
