Crop mover for rotary disc cutter

摘要

A modular disc cutterbar utilizes self-contained cutter modules clamped between alternating spacer modules by fasteners engaged with the spacer modules. Each cutter module has detachably mounted thereon a disc member carrying a pair of opposingly mounted cutting knives pivotally supported on a pivot member to sever standing crop material by impact action upon rotation of the disc member. The disc member also carries on each pivot member above the corresponding cutting knife, but independently movable, a crop mover operable to move the severed crop material away from the corresponding cutting knife. The crop mover has a tapered leading edge that terminates in an outer tip that is narrower than the outer tip of the corresponding cutting knife so as to not interfere with the cutting action of the knife. The crop mover also includes a vertical portion for aggressively moving the severed crop material.
