SIMAR is an acronym for Société Industrielle de Machines Agicoles Rotatives.
These tillers were made in Geneva, Switzerland, and imported by
ROTOTILLER, INC. from 1932 until 1939. After WW II, E. C. Geiger
Co. of North Wales, PA became the sole distributor in the US.
SIMAR exported their tillers to the US until 1975. They
manufactured tillers from 1918 until they stopped production in 1982.
manufactured several size machines. They ranged from 2½ to 10
horsepower, a tilling width of 14" to 36", and weighed from 220 to 880
pounds. ROTOTILLER, INC. purchased the rights to use their engine
and tine configuration for tillers they manufactured.
to information posted on a French SIMAR site, there were 700 of these
tillers made from October 28, 1933 to April 6, 1936 with serial numbers
13001 to 13700. So, this particular tiller may have been built in
1933 with an early s/n of 13049. It has a two-speed transmission,
which is selected by inserting a long plug or pin in either the right
hub for hight speed or the left hub for low speed. It has
separate controls for the tiller and wheel drive. It has ratchet
hubs to aid in turning. The C-30 is a 3hp machine with a 14"
tilling width. The handlebars can be moved up, down, left, and
right to accommodate the operator's comfort.
