Shibaura is a Japanese maker of compact tractors and diesel engines whose units supplied other brands for decades – compact models from Ford/New Holland and Case IH, among others, ran on Shibaura engines or chassis built on Shibaura designs. The ST series spans small garden tractors through compact tractors for grounds care and smallholdings; the type number roughly tracks engine size and power class. Large volumes of Japanese production also reached Europe and North America, where compact tractors of this class became popular for grounds maintenance, orchard work and smaller hobby holdings.

The register lists 9 variants, from the ST 318 and ST 321 to the ST 450 and ST 460, at outputs of 18 to 36 kW (24 to 48 hp); the model with full data has a four-cylinder diesel of 2,216 cc, a kerb weight of 1,905 kg, a lift capacity of 1,486 kg and a rated 2,500 rpm.

In the compact class Shibaura competes directly with Kubota, Iseki and Yanmar; outside Japan the brand is better known as an engine supplier than as a tractor name, since many ST models were sold under other companies' badges.

Buying a used compact tractor of this size, the pto and hydraulic pump matter, along with the condition of front-loader mounts, rust on the frame and leaks from the diesel engine; since identical units ran under several brand names, wear parts can often be sourced through the partner brand's distribution channels too, which keeps these tractors easier to maintain long after a given model left production.
