Soon after buying the 20-35, a friend of the Sleichters said he had seen a 10-18 -- the first Allis-Chalmers model made -- at a nearby farm.
Negotiation commenced almost immediately and the Sleichters added the 10-18 to their growing collection.
Luckily enough, the 10-18 which had been hiding so nearby was in good shape.
Wendel described the 10-18 in his book, Encyclopedia of American Farm Tractors, as "a three-wheeled tricycle type of tractor weighing 4,800 pounds.
The two gas tanks were not the only unusual features the 10-18 had.
Nancy has several other tractors, including a 20-35, a 6-12, a 15-25, an 1830 and the 10-18. She keeps her tractors at the Mennonite Historical Museum in Kalona, Iowa, where they can be viewed and shared with visitors.
The competition was divided into four categories: 0-9 months, 10-18 months, 19-35 months and 3-5 years.
