# Scott Bonnar

Scott Bonnar (c. April 1893 – 1961) was a South Australian engineer, founder of a company which manufactured a range of lawn mowers and other implements, but perhaps best known for their "Model 45" reel, or cylinder, mower.

## History

Bonnar was perhaps born at 57 Watkins Street, Newtown, Sydney, a son of J. J. Bonnar, jun. (1861–1938) and grandson of solicitor J. J. Bonnar. Nothing has been found of his childhood and youth; he may have attended Gilles Street primary school. in 1919 he had a workshop in Bloor Court, off Currie Street, Adelaide, sharpening lawnmower blades.
A company was founded in 1920 by Bonnar and his brother Malcolm Cornelius Bonnar. It is likely, but not certain, that Malcolm was already working as a brass founder. They set up a welding workshop and brass-foundry at 3 Chapel Street, Thebarton, South Australia, manufacturing brassware until at least 1927. By 1924 Scott Bonnar & Co. had a workshop at 22 Mill Street, Adelaide, repairing and regrinding lawn mowers.
In 1926 Scott Bonnar Ltd was formed with £10,000 capital, to take over the business, with shareholders Malcolm Cornelius Bonnar, Scott Bonnar, Percy J. A. Lawrence, Frank William Rose, and H. Gill Williams, all of Adelaide. In that year they began selling electric lawnmowers.
Developments in the 1920s includes a mower which cut a 14-foot (4 metre) swathe while leaving minimal tyre-tracks.
By 1939 their factory was located between Beans Road and Holland Street, Southwark, South Australia. By 1948 they were also making electric hedge trimmers.
In 1950 Scott Bonnar Ltd, lawnmower and brassware manufacturers, was restructured as a public company, whose directors were M. C. Bonnar, M. F. Bonnar, L. W. Harris and A. L. Slade. Bonnar himself took no active part in the company, and removed to Manly, New South Wales. In its first year of trading shareholders received a 12.5% dividend.
The brand "Bonmow" appeared in 1954, for a self-propelled 14-inch reel mower.
The "Model 45" first appeared around 1968, and came out in three reel widths: 14, 17 and 20 inches (36, 43, 51 cm) and three power options: petrol, mains electricity and battery. They also manufactured a "rotary mower", similar to the famous "Victa" brand.
The company was taken over by the manufacturer of Rover mowers, but the Southwark factory did not close until much later.
