Allis Chalmers 620

Last Updated: September 2024

Overview

The Allis Chalmers 620 is a small utility tractor that was made from 1973 to 1975. It's a 2-wheel drive tractor, which means it's best for flat ground and light work. The tractor has a hydrostatic transmission, making it easy to change speeds without shifting gears.

This tractor has a gasoline engine made by Onan. The engine is air-cooled and has 2 cylinders. 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.
