ENGINES OVERVIEW
The Oliver 1755 tractor is powered by either a Waukesha-Oliver 5.1L 6-cylinder diesel or a 4.6L 6-cylinder gasoline engine, providing flexibility for fuel choice based on application needs. The diesel variant offers advantages in torque and fuel efficiency, ideal for heavy-duty tasks, while the gasoline engine may provide easier starting in cold conditions but could be less efficient under load. When selecting between the two, consider the typical workload and fuel availability for optimal performance.
