It's not very powerful compared to other tractors, with only 19.5 horsepower. But it's perfect for small jobs around a farm or garden. The engine is also very small for a tractor, which helps save fuel. The tractor weighs 1,499 pounds, which is quite light for a tractor. It's 82.7 inches long, 47.6 inches wide, and 42.9 inches tall. The Allis Chalmers 620 has some useful features. It has a front and rear PTO (power take-off) that both run at 2000 rpm. This lets you use different tools with the tractor. It has an open operator station, so you can easily get on and off. The tractor also has a hydraulic system, but it's not very powerful compared to bigger tractors. It's a good choice for people who need a small, simple tractor for light work.
