ENGINE DETAIL
The Allis Chalmers 440, powered by a Cummins 555C turbocharged V8 diesel engine, offers robust performance with 218 hp, ideal for heavy-duty applications such as agricultural tasks and material handling. Its high 17:1 compression ratio and 2800 rated RPM enhance fuel efficiency and power delivery, but potential maintenance challenges may arise from the complexity of the 32-valve design. Given its displacement of 9.1L, operators should consider the tractor's weight and maneuverability in tighter spaces, ensuring it's suited for the specific tasks at hand.
