Engine

The engine is not specified in the data provided. However, based on the model name 'Allis Chalmers 25-40', it can be inferred that the tractor is likely powered by a gasoline or diesel engine with a horsepower output of 25-40. The engine is likely air-cooled and has a displacement of around 3-4 liters. It is also likely that the engine has a 4-cylinder configuration and is equipped with a carburetor or fuel injection system.

Transmission

The transmission of the Allis Chalmers 25-40 tractor is a 2-speed gear system. The drawbar horsepower output of the transmission is 27 hp/20.1 kW, while the belt horsepower output is 42.6 hp/31.8 kW. In testing, the drawbar horsepower output was measured at 33.82 hp/25.2 kW, while the belt horsepower output was measured at 47.00 hp/35.0 kW. The transmission is likely a manual system, with the operator manually shifting gears to adjust the speed and power output of the tractor. The transmission is also likely equipped with a clutch system to engage and disengage the gears.

Brakes

The brakes of the Allis Chalmers 25-40 tractor are not specified in the data provided. However, it can be inferred that the tractor is likely equipped with a mechanical braking system, which uses friction to slow down or stop the tractor. The brakes are likely operated by foot pedals, with separate pedals for the left and right brakes. The braking system may also be equipped with a parking brake, which is used to hold the tractor in place when parked.

Steering

The steering system of the Allis Chalmers 25-40 tractor is not specified in the data provided. However, it can be inferred that the tractor is likely equipped with a manual steering system, which requires the operator to physically turn the steering wheel to change the direction of the tractor. The steering system may also be equipped with a power steering system, which uses hydraulic pressure to assist the operator in turning the steering wheel. The steering system is likely a rack-and-pinion system, which provides precise control over the direction of the tractor.

Common Problems

Users of the Allis Chalmers 25-40 tractor have reported several common problems. One of the most common issues is with the chassis, which can become damaged or worn over time. This can lead to reduced stability and control of the tractor, as well as increased wear and tear on other components. Another common problem is with the steering system, which can become stiff or unresponsive. This can make it difficult to steer the tractor, especially at low speeds. Other common problems include issues with the cab, such as leaks or damage to the windows, and problems with the transmission, such as slipping or difficulty shifting gears.
