Interesting Facts

Tractors in the agricultural industry depend on the mighty 4-71N engine day in and day out. This engine utilizes a Power Take Off (PTO) shaft to get things done. Whether it's a combine, harvester or any other form of farm equipment, this engine is a jack-of-all-trades.

The 6-Cylinder 6-71N engine toils away inside mobile cranes everywhere. It powers the tracks that move the crane across tough terrain. Then, it helps lift steel girders by providing hydraulic power to the cable spool.

The 8-Cylinder 8V71N engine helps auxiliary pumps get tough jobs done at oil and gas drilling sites. It's a consistent performer, delivering steady power virtually nonstop--even during fluctuating pressure and flow.
