Research

  • Hay Cutter Function is to cut hay (or the stalks of any plant) near the ground.

Theory

  • Cutting Action results from the movement of a reciprocating sickle bar against a stationary sickle bar. Another general design option is free-spinning knives on whirling discs, which is not chosen for its relatively high danger level and power requirements.
  • Kinetic Power for moving the reciprocating cutting bar is gained from a powered hydraulic motor with a converting mechanism for linear motion.
  • Cut Clearance is the amount of space between the cutting edges of the stationary and reciprocating sickle bars. Cut clearance is required to avoid excessive heat buildup from friction between the stationary and reciprocating cutting bar.
  • Cutting Knives Mounting should use bolting as ease of disassembly for maintenance or replacement purposes.
