Introduction
Satoh S370 Compact Utility Tractor
The Satoh S370 is a compact utility tractor produced between 1977 and 1984. Designed for versatility in agricultural and maintenance tasks, this machine is known for its robust construction and manageable footprint, fitting into the light-duty utility segment of that era.
Engine and Power
The tractor is powered by the Mitsubishi KE70, a two-cylinder, liquid-cooled diesel engine. It features an inline overhead valve configuration with a displacement of 40.8 cubic inches (0.7 liters) and a compression ratio of 20:1. The engine provides 15 gross horsepower (11.2 kW) at a rated speed of 2700 RPM, delivering 13 net horsepower (9.7 kW) for practical work.
Transmission and Drivetrain
The S370 utilizes a non-synchronized gear transmission offering six forward speeds and two reverse speeds. It is equipped with a 7.24-inch dry disc clutch. The tractor was offered in both 4x2 2WD and 4x4 MFWD (S-370D) configurations, providing varying levels of traction. Steering is manual, and the operator maintains control over terrain through a foot-pedal-operated differential lock and mechanical internal expanding shoe brakes.
Hydraulics and PTO
The hydraulic system operates at a pressure of 1920 psi (132.4 bar) with a total flow rate of 3.84 gallons per minute (14.5 liters per minute). It features a rear power take-off (PTO) capable of operating at both 540 and 1000 RPM, allowing for the connection of various implements. The rear hitch is capable of a lift capacity of 1,274 lbs (577 kg) measured at the link ends.

The tractor features an open operator station design. The 2WD model has a wheelbase of 48.23 inches (122 cm) and a total length of 80.90 inches (205 cm), while the 4WD version features a slightly longer wheelbase of 49.80 inches (126 cm).
