Text from the Pioneer Acres website (about the above tractor):



July 5, 1999


Pioneer Acres will be showing off its 1918 Samson Sieve-Grip tractor in the vintage machinery section of the 1999 Calgary Exhibition and Stampede (July 9 - 18). It will then be moved to the Museum for permanent display and demonstration.


This unusual three-wheeled tractor is one of only 7 or 8 remaining in North America. It was manufactured by the Samson Tractor Company of Stockton, California. When Ford went into the tractor business GMC felt the need to make tractors of their own to remain competitive. Rather then start from scratch in the tractor business, GMC bought out Samson. This resulted in the manufacture of only about 140 model 30 X GMC Samson Sieve Grips.


The name Sieve-Grip comes from the tractor's huge steel wheels which utilize metal cleats for traction. When cultivating, the open construction of these wheels help to break up the ground instead of packing it. It was intentionally built low to go under fruit trees in orchards. A seated driver cannot see the front wheel over the long hood. A large arrow is attached to the steering mechanism to indicate the direction of the front wheel.


The 5,800-pound beast is powered by a gargantuan 425-cubic-inch inline four cylinder gasoline engine equipped with a unique Remy electric governor (early form of cruise control). Also out of the ordinary is a water-filled air cleaner descriptively labelled Nodust Moisto Rizer. Top speed is 3.5 miles per hour and the braking system is rudimentary metal-to-metal. The clutch is virtually identical to steam-driven tractors of the era.


This rare tractor has been restored during the past winter and spring. It was purchased in the 1960's by a Pioneer Acres member who spent the rest of his life collecting parts for it. Unfortunately, by the time he had everything he needed he was ill with cancer and passed away in the fall of 1998. The project was completed in his memory by a long-time friend who is also a member of the Club. Some parts had to be hand-fabricated.


Many Samson/GMC Sieve-Grips were used in Western Canada as well as in the U.S.
