Waterloo Boy P

The Waterloo Boy P is a half-track crawler tractor built in 1913 by Waterloo Boy in Waterloo, Iowa, USA. Records on this model are incomplete. Advertisements of the era show "Sure Grip, Never Slip" written on the cooling tower, and some have assumed this to be the model name. The model P designation is suggested in the January/February 1995 issue of Two-Cylinder Magazine. The tractor appears to have been based on the unsuccessful Parkhurst-designed Waterloo Boy Standard tractor. It features a 4-cylinder liquid-cooled gasoline engine from the Waterloo Gasoline Engine Company, a 1-speed unsynchronized gear transmission with 1 forward and reverse gear, and is designed as a half-track with manual steering. It can pull 4-5 14-inch plows and uses tracks for rear/agricultural tires.
