One Mighty Tractor
Samson Sieve-Grip lived up to its name
By James N. Boblenz
According to Bill Vossler’s Orphan Tractors, J.M. Kroyer started the Samson Iron Works in 1884 to make engines and pumps to handle winter water runoff around Stockton. Samson began manufacturing tractors early in the 20th century. By 1913, the Samson won the California State Fair competition against all comers in its size category. About a year later, the tractor was offered in two sizes: a 6-12 model and a 10-25. Both were called Sieve-Grips.
Named for unique tread
The Sieve-Grip’s wheel tread design was unusual. Although the Samson used cleats, its open wheel design was unique among tractors. Samson’s ads claimed the open tread provided better traction in the area’s hilly terrain.
