Field Work Rate with effective implement width of 100 ft: a worked example

This scenario runs the field work rate calculation on the strong side: effective implement width of 100 ft, with every other input held at its documented default. Use it to schedule planting, spraying, tillage, spreading, mowing, or harvest support passes.

The inputs for this scenario

  • Effective implement width: 100 ft (raised for this scenario; the documented default is 40)
  • Field ground speed: 6 mph (unchanged)
  • Field efficiency: 0.82 x (unchanged)
  • Acres-per-hour unit conversion: 0.12 x (unchanged)

Working through the calculation

  • Applying the documented formula (Field work rate = implement width x ground speed x field efficiency x 0.1212) to the inputs above produces each figure below.
  • At this operating point the engine returns 59.63 acres / hr for field work rate, the number this scenario is built around.
  • At this operating point the engine returns 492 value for theoretical field coverage rate.
  • At this operating point the engine returns 0.12 x for acres per hour conversion factor.
  • At this operating point the engine returns 600 value for width times speed.

How this compares with the baseline

  • Against the tool's baseline example, where effective implement width sits at 40 ft and the headline result is 23.85 acres / hr, this scenario comes in 150% above the baseline at 59.63 acres / hr.
  • Use it when planning how many machines or hours a field or planting window needs, or when quoting custom acres. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Field work rate: 59.63 acres / hr (headline result)
  • Theoretical field coverage rate: 492 value
  • Acres per hour conversion factor: 0.12 x
  • Width times speed: 600 value
