Overview

Manufacturer

Allis ChalmersReference

The shuttle transmission is controlled using the gear shift lever and the shuttle control lever. The tractor must be stopped, and clutch used, to select one of four speeds with the gear shift. The shuttle control lever enables a shift between forward, reverse, or neutral without clutching. A PTO could be ordered on the industrial D15 with the shuttle, but it ran at 875 RPMs.Reference
