Kubota KH-66: Engine Specifications

Updated April 17, 2017

The Kubota KH 66 is a small tractor built between 1988 and 1992, with a three-cylinder engine. The compact, "mini excavator" has a simple construction and resembles a phone booth on treads. Kubota tractors were first designed for Japanese agriculture, where small plots of land required compact tractors with tight maneuverability, according to the company. Kubota manufactures tractors for garden and construction, as well as attachments, pumps, generators and tractor implements.

The Kubota KH 66 has a gross weight of 1270 Kilogram, with a three-cylinder engine. The vehicle runs on a D905-E Kubota engine, which powers either a mini digger or a generator. The three or four-cylinder engines feature an 0.9 to 1.5-litre displacement, with gas, diesel, liquid propane, dual-fuel and turbocharged versions. The engine features low and high fan settings, one-sided maintenance for ease and a displacement of 0.90 litres.


The engine and hydraulic system lends the KH-66 a deceptive amount of power, according to distributors. Meanwhile, the mini machine can manoeuvre in backyards and construction sites, where larger excavators could not easily go. The KH-66 and other mini-diggers don't bear down with as much weight on soil containing piping or other structural elements. The mini class of tractors weigh between one and seven tons.


The tractor runs on a set of two rubber treads over steel tracks. The tractor also features three bucket implements, for ditching, trenching and digging bucket, with a quick hitch, swivel boom, and a 57-inch (1,450mm) blade. The Spring Quick Hitch coupler was designed to the used with the Kubota KH series, as well as the JCB 801 and JCB micro models. The hitch secures implements to the tractor. A 25-mm hitch pins a 95-mm arm and link spacing and 90-mm pin centres.
