Subtopic: Forage Harvesters

Question Statement:

In a flywheel-type forage harvester, the theoretical length of cut (TLC) of green fodder is reduced by:

Options:

  • (A) Increasing the number of cutting knives or decreasing the feed roll speed
  • (B) Decreasing the number of cutting knives
  • (C) Increasing the feed roll speed
  • (D) Decreasing the cutterhead rotational speed

Answer Key:

A

Step-by-Step Solution & Explanation

Theoretical length of cut $TLC = \frac{v_{feed}}{N \times K}$, where $K$ is number of knives and $N$ is cutterhead rpm. Increasing knives or slowing feed rolls yields shorter cut particles.
