Engine

The engine is not specified in the data provided. However, based on the model name 'Allis Chalmers 620', it is likely that the engine is a gasoline-powered internal combustion engine. The engine is expected to have a displacement of around 0.8L and a power output of approximately 19.5hp / 14.5kW. It is also expected to have a paper element air cleaner, a compression ratio of 7:1, and a rated RPM of 3600.

Transmission

The transmission is a hydrostatic type with infinite (3-range) forward and reverse gears. The engine specified in the data is expected to power the hydrostatic transmission. The hydrostatic transmission is known for its smooth and seamless operation, making it ideal for applications that require precise speed control. The hydrostatic transmission is also expected to be easy to operate, with simple controls that allow the operator to adjust the speed and direction of the tractor with ease.

Brakes

The brakes are not specified in the data provided. However, based on the model name 'Allis Chalmers 620', it is likely that the tractor is equipped with mechanical drum brakes. The brakes are expected to be located on the rear wheels of the tractor and are operated by foot pedals. The brakes are designed to provide reliable stopping power, even when the tractor is carrying heavy loads or operating on steep inclines. The brakes are also expected to be easy to maintain and service, with simple components that can be easily replaced if necessary.

Steering

The steering is powered by an Onan 0.8L 2-cylinder gasoline engine. The steering system is expected to be a manual steering system, with a steering wheel that allows the operator to control the direction of the tractor. The steering system is designed to be responsive and easy to operate, allowing the operator to make precise turns and maneuvers with ease. The steering system is also expected to be durable and reliable, with components that are designed to withstand the rigors of heavy use.

Common Problems

Users of the Allis Chalmers 620 have reported several common problems with the tractor. One of the most common issues is with the hydrostatic transmission, which can sometimes fail or become difficult to operate. Another common problem is with the brakes, which can wear out quickly if the tractor is used frequently or for heavy-duty applications. Some users have also reported issues with the steering system, which can become loose or unresponsive over time. Finally, some users have reported issues with the engine, which can sometimes fail to start or run poorly if not properly maintained.

What Users Like

Users of the Allis Chalmers 620 appreciate several features of the tractor. One of the most popular features is the hydrostatic transmission, which provides smooth and precise control of the tractor's speed and direction. Users also appreciate the tractor's durable construction, which allows it to withstand heavy use and rough terrain. The tractor's compact size and maneuverability are also popular features, as they make it easy to operate in tight spaces or around obstacles. Finally, users appreciate the tractor's versatility, as it can be used for a wide range of applications, from mowing lawns to hauling heavy loads.
