Introduction
Allis-Chalmers 616 Garden Tractor
The Allis-Chalmers 616 is a garden tractor produced between 1972 and 1975. Manufactured by Simplicity in Port Washington, Wisconsin, this model was designed to serve as a versatile utility platform for property maintenance and light-duty landscaping tasks.
Engine and Powertrain
The tractor is powered by an air-cooled, two-cylinder opposed-twin engine with a horizontal shaft. It features a displacement of 816 cc (49.8 ci) and generates 16.5 gross horsepower (12.3 kW) at a rated speed of 3600 RPM. The engine uses a paper element air cleaner and requires an oil capacity of 3.3 liters.
Transmission and Hydraulics
The 616 utilizes a Sundstrand shift-driven hydrostatic transmission, providing infinite forward and reverse speeds across three distinct ranges. This allows for precise speed control during operation. The hydraulic system operates at a pressure of 500 psi (34.5 bar) with a pump flow of 2.25 gpm (8.5 lpm), and has a total fluid capacity of 4.7 liters.
Mechanical and PTO Systems
Built with a two-wheel drive chassis, the tractor features manual steering and disc brakes for operator control. It is equipped with an independent rear PTO (2000 RPM) and an independent front PTO (3600 RPM), both utilizing electric clutches to engage implements, such as the standard 60-inch mower deck.
Dimensions and Chassis
The machine has a wheelbase of 142 cm (56 inches) and an overall length of 210 cm (83 inches). Its shipping weight is approximately 589 kg (1300 lbs). The open operator station provides visibility, and the tractor offers adjustable tread widths for both the front (88 to 95 cm) and rear (86 to 101 cm) axles to accommodate different terrain conditions.
Conclusion
The Allis-Chalmers 616 is a durable garden tractor suited for residential property maintenance. Its hydrostatic transmission and independent PTO configuration make it a capable machine for users requiring a reliable, maneuverable platform for mowing and small-scale yard work.
