sedan styles, enclosed cargo styles and open bed configurations were all available. Model numbers designated the configuration of the unit, for example a Model 342 was a "300" series, four-track, two-door Tucker Sno-Cat. A Model 443 would be a "400" series, four-track, three-door unit. In the early models, there were ultimately series 200 through 900, with the higher numbers being larger units. The 500 series
Tuckers employed extra wide tracks which allowed them to carry heavy loads in very deep soft snow conditions. The early model Tucker Sno-Cats all utilized a unique steel track that revolved around a steel pontoon, the steel pontoons were eventually replaced by fiberglass pontoons. As the models evolved, the steel tracks were replaced with a suspension system that employed rubber belts that were carried by a series of small wheels. Fastened to the exterior of the rubber belts are cleats, also called

There are at least two variants of the Tucker Kitten, some have square corner doors while others have rounded corner doors. The Kitten was powered by a 10 hp engine. Additionally there was at least one prototype featuring two tracks and a mid-engine design.

The more common four track Tucker Sno-Cats are considered to be the classic Sno-Cats in
American history and have been used extensively in both polar regions for exploration, as well as for transportation, trail grooming and industrial applications. The body style could be configured in many ways and

Steel tracks revolving around pontoons were replaced with a system that employed two rubber belts with metal cleats, or grousers, attached to the outside perimeter to grip the snow. A series of wheels and guides were used inside the belts. Two drive sprockets on a hub drive the rubber belted track.

models and early production models used two sets of tracks. Initially Tucker Sno-Cats employed two front-mounted steering skis and two sets of tracks mounted to the rear. However, there are at least three production models that only employed dual tracks—the small 222 Tucker Kitten, the 322, and the

Tucker Sno-Cats were originally built with a steel track that rotates around a steel pontoon. Located at the top center of the pontoon is a drive sprocket with teeth that drive the chain-like tracks around the steel pontoon. Due to maintenance issues with rust on the steel pontoons, fiberglass
