Stihl S 20
The Stihl S 20 is a compact 2WD tractor designed for small farms and gardens. It has a 4x2 chassis and runs on an air-cooled diesel engine made by MWM. The engine, model AKD 10Z, has 2 cylinders and produces 20 hp at 3000 rpm. It's naturally aspirated, which means it doesn't use a turbocharger. This tractor has a simple transmission with 6 forward gears and 1 reverse gear. It's not synchronized, so you need to stop before changing gears. The S 20 is quite small, measuring 57.9 inches wide and 63 inches tall. It weighs 2162 lb, making it easy to move around. The tractor uses agricultural tires, with smaller ones in front and larger ones in the back. You can adjust the rear wheel spacing from 49.2 to 59.1 inches to fit different row widths. The S 20 starts with an electric starter, which is more convenient than a manual crank.
