Author: Diesel Progress North American Edition

Kubota Tractor Corp. (KTC) has introduced two compact tractors designed for ag and utility equipment applications. The B7800HSD compact tractor is built on the platform of the established, top-of-the-line B2910 tractor, while the M4800SU is designed to be a basic economical, two-wheel drive machine.

The B7800HSD tractor is powered by a Kubota V1505-E diesel rated 30 hp. The engine is a four-cylinder, liquid-cooled unit that features the company's E-TVCS combustion system. It directly drives a Kubota hydrostatic transmission that features three operating speed ranges for greatest efficiency. Speed and direction are controlled through a single pedal, with no clutching required.

The engine also drives dual Kubota hydraulic pumps that operate work and steering circuits. The main pump has a flow rate of 6.4 gpm, while the steering pump delivers 3.09 gpm. The use of two pumps ensures versatile implement operation with enough power for efficient work and smooth steering, the company said.

The Category I, three-point hitch incorporates a new Kubota-designed quarter inching valve that acts as a regulator, enabling the operator to make smaller adjustments at the lower link end. The lever guide can move in quarter--inch, increments making attaching/detaching implements easier while enhancing grading performance.
