Calculating the ROI for the use of a stripper front in the Mallee locations
Aims

To determine the ROI from using a stripper front compared to a draper front.

Key messages
  • Capital value improvement of $61,000 by using the stripper front.
  • The cost per rotor hour of the machine increased as the capital cost went up and the number of hours decreased.
  • There was a 24% reduction in fuel usage and a 16% reduction in labour costs.
  • Harvest was completed on average two to three days faster with a stripper front.
