Introduction

Allis Chalmers 712 Garden Tractor

The Allis Chalmers 712 is a garden tractor produced between 1974 and 1979 in Port Washington, Wisconsin, USA. Designed for residential property maintenance and landscaping tasks, this two-wheel drive machine combines a compact footprint with versatile transmission configurations.

Engine and Power

The tractor is powered by a 12 hp (8.9 kW) air-cooled engine with a horizontal shaft and a displacement of 29.1 cubic inches (476 cc). The engine operates at a rated speed of 3600 RPM. It features an electric starter system, a dry-type air cleaner, and requires an oil change every 25 hours of operation to maintain performance.

Transmission and Drivetrain

The 712 model offers two distinct transmission options to accommodate different operator preferences: a 4-speed shuttle transmission or a belt-driven hydrostatic transmission providing infinite forward and reverse speeds. Both systems utilize a manual clutch and feature an independent mid-power take-off (PTO) for implement operation.

Mechanical and Electrical Systems

The machine is equipped with a 12-volt electrical system featuring a 45 Ah battery and a 15-amp charging system powered by a flywheel alternator. Mechanical features include manual steering and drum brakes. The operator station is of the open type, and the tractor can be fitted with an optional sleeve hitch for towing or light-duty implement mounting.

Dimensions and Tires

With a wheelbase of 48.1 inches (122 cm) and a ground clearance of 8 inches (20 cm), the tractor is optimized for stability on lawn surfaces. It utilizes 16x6.50-8 front tires and 23x8.50-12 rear tires, with total weight varying between 785 lbs and 805 lbs depending on the transmission type.

Conclusion

The Allis Chalmers 712 remains a functional choice for garden maintenance, compatible with 42-inch or 48-inch mower decks. Its simple mechanical design and choice of manual or hydrostatic transmissions make it suitable for homeowners requiring a reliable, long-term solution for lawn care.
