Allis Chalmers D15 vs Allis Chalmers K

Verdict: Allis Chalmers D15 vs Allis Chalmers K

The Allis Chalmers D15 and the Allis Chalmers K are both tractors — here is how they stack up on the figures that matter. Allis Chalmers D15 leads on rated power with 40 hp against 36 hp. Allis Chalmers D15 is the lighter machine (3,985 kg vs 5,216 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.

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

The four-speed transmission was introduced in 1935 at tractor serial number 4451.Reference
