Introduction

Jacobsen 125 Garden Tractor

The Jacobsen 125 is a garden tractor produced between 1972 and 1973. Marketed by Oliver and manufactured by Jacobsen, this machine was designed primarily for residential lawn maintenance and versatile yard work.

Engine and Performance

The tractor is powered by a Kohler K301AS gasoline engine. This 476 cc, single-cylinder, air-cooled unit features a horizontal shaft configuration and generates a gross power output of 12 hp (8.9 kW) at a rated speed of 3600 RPM. The engine utilizes a dry-type air cleaner and has an oil capacity of 2.125 quarts (2.0 L).

Transmission and Drivetrain

Users could select between two transmission types: a belt-driven gear transmission providing four forward and one reverse gear, or a shaft-driven hydrostatic transmission allowing for infinite speed control in both directions. The tractor is a two-wheel-drive platform equipped with mechanical band brakes and manual steering.

Power Take-Off and Hydraulics

The machine is equipped with an independent front power take-off (PTO). This system utilizes an electric clutch and a pulley-type drive mechanism, allowing the operator to engage front-mounted attachments such as mower decks, which were available in 42-inch and 50-inch sizes.

Dimensions and Chassis

The Jacobsen 125 features a 48-inch wheelbase and an overall length of 71.7 inches. The width at the tires is 38 inches. Depending on the transmission configuration, the tractor weighs between 750 lbs (340 kg) for the gear-driven model and 770 lbs (349 kg) for the hydrostatic version. It is fitted with lawn and turf tires, specifically 16x6.50-8 on the front and 23x8.50-12 on the rear.

Conclusion

With its open operator station, sleeve hitch capability, and choice of transmissions, the Jacobsen 125 serves as a classic utility platform for homeowners and light-duty groundskeeping tasks requiring varied implement usage.
