An overloaded thresher typically shows

  • A.No change until the machine stalls
  • B.Improved cleaning efficiency
  • C.Rising unthreshed and separation losses together
  • D.Falling grain damage and rising efficiency

Answer: C

Too thick a mat prevents grain from reaching the concave and from shaking free on the walkers, so both loss terms climb at once. Capacity is normally defined as the feed rate at which total loss reaches an accepted figure.
