LAUSON ENGINES

Various models could be fitted with accessories such as stubshafts, high octane equipment, deep bases with low oil level shut off switch, spill proof features, rain proof features, gear reductions and other accessories. Vertical crankshaft models were also available although they are not shown.

In 1949 models TLH 3 HP and RSH 2 HP were introduced. These were horizontal crankshaft models.

Lauson also manufactured a line of 4 cycle air-cooled outboard motors between 1941 and 1956, which were known as the Sport King. In 1948 two completely new designs were offered, a single cylinder 3 HP model and a twin cylinder 6 HP model.

During the '30's and '40's Lauson also manufactured a line of 4 cycle, water cooled inboard marine engines. In 1949 four models were offered: PMM-827, 5 HP; PMM-826 3 HP; LF-848, 3.7 HP and RCM-826, 1-1/2 HP.

In December 1955, Lauson was purchased from Hart-Carter by Tecumseh Products Company of Tecumseh, Michigan.

In 1956 four new vertical crankshaft mower engines were added to the line and in that same year, the line was made up of the following models: V 17, 1.75 HP, V 20, 2 HP; V22, 2.75 HP; V 25, 2.5 HP; V 27, 2.75 HP; CH 17, 1.75 HP; CH 20, 2 HP; RSH 737, 2 HP; TLH 725, 3.3 HP; P 25, 6.3 HP. Models beginning with a 'V' are vertical shaft.

In 1957 Tecumseh purchased the Power Products (2 cycle) engine facility in Grafton, Wisconsin and in that same year combined the parts and service facilities of both Lauson and Power Products to form the Lauson-Power Products Parts Depot Division with offices and warehouse in Grafton.

Over the years, Tecumseh has added, dropped or changed engine models to keep the Lauson one of the most modern 4 cycle, air cooled engines in the world.

The Lauson line today is very complete and consists of the following models: Lawnmower, Aluminum, vertical shaft; LAV30RM, 3 HP; LAV35RM, 3.5 HP; LAV40 RM, 4.0 HP; Aluminum, Vertical Shaft; LAV301A, 3 HP; LAV351 A, 3.5 HP; LAV401A, 4 HP; LAV501A, 5 HP; V60, 6 HP; VM70, 7 HP; VM80, 8 HP; Cast Iron, Vertical Shaft, VH50 5 HP; VH60, 6 HP; VH70, 7 HP; VH80, 8 HP; VH100, 10 HP; Lawnmower, Aluminum, horizontal shaft: H25, 2.5 HP; H30, 3 HP; H35, 3.5 HP; H40, 4 HP; H550, 5 HP; H60, 6 HP; HM70, 7 HP; HM80, 8 HP; Cast Iron, horizontal shaft: HH50, 5 HP; HH60, 6 HP; HH70, 7 HP; HH80, 8 HP; HH100, 10 HP; HH120, 12HP; HH140, 14HP; valve-in-head; HH150, Valve-in-head; HH160, 16 HP, valve-in-head.
