The John Deere 350B is a crawler tractor that was produced from 1970 to 1974, signifying its established presence in the industry during that era. Designed for varied applications including loading and construction, the tractor featured a robust crawler chassis. It came with a choice between a diesel and gasoline engine, each with a 3-cylinder inline configuration. For the diesel engine variant, it offered a displacement of 152.0 cubic inches, while the gasoline variant had a slightly smaller displacement of 135.0 cubic inches. The 350B model featured a gear-driven transmission with the functionality to upgrade to a shuttle type, delivering versatility in operational gears with 4 forward and up to 4 reverse gears for shuttle transmission equipped models. Suitable for heavy-duty tasks, this crawler's open operator station coupled with clutch-brake steering and contracting band brakes highlight its utility focus. Despite its power, the flat 12-inch width of the model provides a compact profile suitable for the varying demands of construction, excavation, or agricultural tasks.
