Introduction

Jacobsen GT-12H Garden Tractor

The Jacobsen GT-12H is a two-wheel drive garden tractor manufactured by Jacobsen in Racine, Wisconsin, USA. Produced between 1972 and 1976, this machine was designed for residential lawn care and property maintenance tasks.

Engine and Performance

The tractor is powered by a Kohler K301AS, a 1-cylinder, air-cooled, horizontal-shaft gasoline engine. It features a displacement of 476 cc and delivers a gross power output of 12 hp at a rated speed of 3600 RPM. The engine cooling system relies on forced air circulation, and it requires an oil capacity of 2.1 liters.

Transmission and Drive

The GT-12H utilizes a shaft-driven hydrostatic transmission. This system provides infinite forward and reverse speed control across two operational ranges, allowing for precise maneuverability without the need for traditional gear shifting.

Operator Controls and PTO

The operator station is an open-platform design, with an optional vinyl weather cab available for environmental protection. Steering is manual, and braking is managed by mechanical band brakes. The tractor features an independent front PTO driven by a pulley system, which is engaged via an electric clutch for efficient implement operation.

Dimensions and Tires

With a wheelbase of 116 cm and an overall width of 96 cm, the GT-12H is built for compact spaces. It sits on 16x6.50-8 front tires and 23x8.50-12 rear tires, specifically designed for lawn and turf applications to minimize surface disruption.

Conclusion

The Jacobsen GT-12H is a dependable garden tractor suited for landowners requiring a versatile machine for mowing and light utility work. Its combination of a hydrostatic transmission and an electric-clutch PTO makes it an effective tool for those managing medium-sized properties.
