Introduction
Allis Chalmers ED40 Utility Tractor
The Allis Chalmers ED40 is a utility tractor produced in Essendine, Lincolnshire, England, between 1960 and 1968. Designed for general farm operations, this two-wheel-drive machine is built with a focus on mechanical simplicity and operational durability.
Engine and Performance
The tractor is powered by a Standard Ricardo 23C four-cylinder diesel engine with a displacement of 2.3 liters (137.89 ci). This liquid-cooled unit produces 41 horsepower (30.6 kW) at a rated engine speed of 2000 RPM. The engine features a glow plug pre-heating system to assist with cold starts and relies on a 12-volt starter.
Transmission and Drivetrain
The ED40 utilizes a gear-type transmission providing eight forward speeds and two reverse speeds. Power is transferred through a 254mm dry disc clutch. The tractor is configured as a two-wheel-drive model, equipped with mechanical drum brakes and a mechanical rear differential lock to improve traction during field operations.
Hydraulics and PTO
The hydraulic system is an open-center design capable of delivering a pump flow of 6.4 gpm (24.2 lpm) at a system pressure of 2500 psi (172.4 bar). The rear PTO is a live, optional feature operating at 540 RPM, which is achieved at an engine speed of 1700 RPM. A Category I rear hitch provides a lift capacity of 2500 lbs (1134 kg) at the ends.
Dimensions and Chassis
With a wheelbase of 76.4 inches (194 cm) and a total length of 114 inches (289 cm), the ED40 maintains a compact footprint. The tractor has a base weight of 3527 lbs (1599 kg). The front tread is adjustable from 48 to 70 inches, and the rear tread is adjustable from 48 to 72 inches, allowing the machine to be adapted to various row crops.
Conclusion
The Allis Chalmers ED40 remains a representative utility tractor of its era, characterized by its reliable 4-cylinder engine and straightforward mechanical layout. It is well-suited for light to medium-duty agricultural tasks, offering the versatility required for small to mid-sized farm operations.
