Introduction
Stihl S 20 Agricultural Tractor
The Stihl S 20 is a compact tractor produced between 1960 and 1961. Designed for light agricultural tasks, this two-wheel-drive machine is recognized for its mechanical simplicity and utility in small-scale farming operations.
Engine and Performance
The tractor is powered by an MWM AKD 10Z two-cylinder diesel engine. This air-cooled unit has a displacement of 1.0 liters and produces 20 hp (14.9 kW) at a rated engine speed of 3000 RPM. The engine cooling is managed through air circulation, which eliminates the need for a liquid cooling system, simplifying maintenance requirements.
Transmission and Drivetrain
Power is transferred to the wheels via a Hurth 819 transmission system featuring a single dry plate clutch. The gearbox provides 6 forward speeds and 1 reverse speed using an unsynchronized gear arrangement. The tractor utilizes a two-wheel-drive configuration and is equipped with band brakes to manage stopping power.
Hydraulics and PTO
For the operation of external implements, the S 20 is equipped with an independent rear power take-off (PTO). This system operates at a standard speed of 540 RPM, allowing for the consistent use of various agricultural attachments compatible with this power class.
Dimensions and Handling
The tractor features an open operator station designed for direct visibility. It has a total weight of 2,162 lbs (980 kg) and measures 57.9 inches in width. The standard tire configuration consists of 4.50-16 front tires and 7.00-30 rear tires, though several optional sizes were available to adapt the machine to different field conditions.
Conclusion
The Stihl S 20 serves as a functional vintage workhorse, well-suited for light agricultural duties or collection purposes. Its compact dimensions and straightforward mechanical design make it an accessible option for those requiring a maneuverable, low-maintenance tractor.
