Introduction

Jacobsen 105 Garden Tractor (1972-1973)

The Jacobsen 105 is a garden tractor produced between 1972 and 1973, distributed by Oliver and manufactured by Jacobsen. Designed primarily for residential landscaping and garden maintenance, this model is recognized for its straightforward mechanical configuration and compatibility with various attachments.

Engine and Performance

The tractor is powered by a Kohler K241AS gasoline engine, a single-cylinder, air-cooled unit with a horizontal shaft. It features a displacement of 391 cc (23.9 ci) and a bore/stroke ratio of 3.25 x 2.875 inches. With a gross power output of 10 hp (7.5 kW) at a rated 3600 RPM, the engine provides sufficient torque for mowing and light utility tasks.

Transmission and Drivetrain

The drivetrain utilizes a belt-driven gear transmission system, offering 4 forward gears and 1 reverse gear. The system is engaged via an idler pulley clutch. Power is delivered to the rear wheels in a two-wheel-drive configuration. The machine is equipped with manual steering and mechanical band brakes to ensure operator control.

Hydraulics and Attachments

The unit includes an independent front PTO (Power Take-Off) with an electric clutch and a pulley-type drive, allowing for the operation of front-mounted implements. Additionally, a sleeve hitch is available as an optional feature to accommodate rear-mounted garden implements. The tractor is compatible with 42-inch or 50-inch mower decks.

Dimensions and Chassis

Built on a 48-inch wheelbase with a total length of 71.7 inches and a width of 38 inches at the tires, the Jacobsen 105 is designed for maneuverability in confined spaces. The operator station is of the open type. It features lawn/turf tires, specifically 16x6.50-8 on the front and 23x8.50-12 on the rear, providing stability while minimizing surface impact on lawns.

Conclusion

"The Jacobsen 105 is a compact, mechanically simple garden tractor suitable for homeowners and collectors focused on light-duty landscaping. Its reliance on a standard Kohler powerplant and a belt-driven transmission makes it a manageable machine for maintenance and restoration."
