ENGINE DETAIL
The Allis Chalmers WS tractor features a robust 4-cylinder gasoline engine with a notable displacement of 675.1 cubic inches (11.1 liters), providing significant torque at a rated RPM of 1050, ideal for heavy-duty tasks. Its oil bath air cleaner enhances engine longevity by effectively filtering contaminants, while the 5:1 compression ratio indicates lower power output, but increased fuel efficiency for prolonged operation. However, the relatively low rated RPM might limit its performance in speed-dependent agricultural applications; thus, it excels in torque-centric scenarios like plowing or hauling.
