Abstract
A disc mower conditioner utilizing a modular disc cutterbar to sever standing crop material by impact action. The side sheets of the disc mower conditioner are provided with a rolling crop divider that can be an optional attachment. The rolling crop divider is constructed as a series of overlapping rolling coulters mounted to the side sheet by bearings to enhance the rolling operation of the coulters. The rolling coulters effectively divide the crop material to direct tall and entangled crops into the header to be severed by the rotating knives. The coulters are arranged in a trailing orientation to present a curved leading edge that is highly effective in directing tall, entangled or viney crops downwardly into engagement with the adjacent disc cutter.
Claims11
In a mower conditioner having a mobile frame;
- a crop harvesting header suspended from said frame for movement relative thereto and including a cutterbar forwardly positioned from said header to sever standing crop material from the ground;
- said header having laterally opposing side sheets and a shroud encircling said cutterbar and being connected to said side sheets, the improvement comprising:
- a rolling crop guide formed of rotatable members detachably connectable to said side sheets to separate and guide crop material toward said cutterbar for engagement therewith to sever said crop material.
In a hay harvesting machine having a mobile base unit and a crop harvesting header supported on said base unit for severing crop material from the ground, said header having laterally opposed side sheets extending in a generally fore-and-aft position, the improvement comprising:
- a rolling crop divider having at least two rotatable members rotatably supported on at least one of said header side sheets.
In a hay harvesting machine having a mobile base unit and a crop harvesting header supported on said base unit, said header having a disc cutterbar transversely extending between laterally opposed side sheets for severing crop material from the ground, the improvement comprising:
- two coulters rotatably supported on each of said header side sheets in an overlapping orientation with respect to one another to form a rolling crop divider having a curved forward edge to separate standing crop material and guide crop material into said disc cutterbar to be severed thereby.
