Jacobsen GT-12: The 1970s Garden Tractor That Still Impresses!

Step back in time with the Jacobsen GT-12, a garden tractor from the golden era of 1972-1976 that continues to be a reliable workhorse for homeowners. This compact powerhouse, manufactured by Jacobsen in Racine, Wisconsin, USA, offers a blend of simplicity, durability, and functionality that makes it a standout even today.

A Heart of Reliability: The Kohler Engine

Under the hood, the GT-12 is powered by a robust 1-cylinder, air-cooled, horizontal-shaft gasoline engine from Kohler, specifically the K301AS model. This engine delivers a solid 12 hp [8.9 kW] and displaces 476 cc [29.07 ci], ensuring enough grunt for various garden tasks. With a rated RPM of 3600 and a bore/stroke of 3.375x3.25 inches [86 x 83 mm], this engine is built for endurance. It features a 12-volt starting system and a 24 Ah battery, supported by a 15-amp charging system, guaranteeing consistent power delivery.

Agile and Controlled: Mechanical Prowess

The GT-12 boasts a practical two-wheel-drive system paired with manual steering, offering precise control for navigating tight spaces and complex terrain. Its mechanical band brakes provide reliable stopping power. The open operator station ensures good visibility, with a vinyl weather cab available as an option for enhanced comfort during inclement weather.

Versatile Power Take-Off (PTO)

When it comes to attachments, the GT-12 doesn't disappoint. It features an independent front PTO with an electric clutch, offering the flexibility to power various implements smoothly. The front PTO type is a pulley system, further enhancing its adaptability for different operational needs.

Compact Dimensions for Everyday Use

Measuring a wheelbase of 46 inches [116 cm] and a width of 38 inches [96 cm], the GT-12 is designed for maneuverability. Its length is 71.7 inches [182 cm], and it offers ample ground clearance with 9.125 inches [23 cm] at the front axle and 6.625 inches [16 cm] at the rear axle. The tractor is fitted with lawn/turf tires, 16x6.50-8 at the front and 23x8.50-12 at the rear, ensuring minimal impact on your lawn.

Adaptable Transmission and Hitch

Power is efficiently transferred through a belt-driven gear transmission, providing 4 forward and 1 reverse gears. The clutch system utilizes an idler pulley for smooth engagement. For added versatility, the GT-12 is equipped with a sleeve hitch, available as an option, making it easy to connect a variety of ground-engaging implements.

Conclusion

"The Jacobsen GT-12 stands as a testament to solid American engineering from the 1970s.
