The term power cycle, when used in the context of operating a backhoe front-end loader, specifically refers to the RPM range where the engine exhibits optimum power output. Operating an engine within this range allows it to deliver the best balance of performance and efficiency, thus maximizing productivity while minimizing fuel consumption.

During this power cycle, the engine can perform at its best capacity, providing the torque needed to lift, dig, and transport materials effectively. Understanding the ideal RPM limits assists operators in maintaining the machine's performance while ensuring that wear and tear on the engine are reduced.

Other options refer to different aspects of the machine's operation or performance. While fuel efficiency is important, it is not solely determined by the power cycle. The time taken to complete a full load cycle involves operational efficiency rather than the engine's performance characteristics. Lastly, engine temperature, although critical for monitoring the overall health of the machine, does not define the concept of a power cycle.
