A harvester machine includes a plurality of harvester units that can be positioned side-by-side in a row that extends across the direction of operative travel in front of a tractor. The tractor is connected to a first coupling to push the machine when processing crop and a second coupling at one side of the machine can be used to tow the machine during transport; the units then being located one behind the other. Each unit includes cutting, threshing and cleaning means and a delivery device communicates with the units to remove grain through one or more outlets that extend over the tractor to a rear container. The units are interconnected by pivot connections at their sides with pivot axes extending in the direction of operative travel. Adjustable castor wheels support the units at the desired height and a common drive from the tractor engages the various threshing, cleaning, mowing and delivery devices including blowers.
A harvester machine for attachment to a tractor comprising a plurality of harvester units, said units each having a frame and the frames of the units being interconnected by pivot means which are provided at their adjacent sides, said units extending transversely side by side relative to the direction of operative travel, each said unit comprising cutting, threshing and cleaning mechanisms, common coupling means for said units on the machine for connection to a three point lifting hitch provided at the front of the tractor, a container attached at the rear of the tractor wherein a delivery device is positioned to receive processed crop from at least one harvester unit, said device having at least one outlet conduit extending over the tractor to its rear with an opening above said container.
A harvester machine for attachment to a tractor comprising a plurality of harvester units, said units each having a frame, said frames of the units being interconnected by pivot means provided at their adjacent sides, said units extending side by side transverse to the direction of the machine's operative travel, each unit comprising cutting, threshing and cleaning mechanisms, driving means connected to said mechanisms, said driving means including a transmission located between two centrally positioned of said units, and delivery outlet means mounted on the latter two units, said threshing mechanisms of each unit comprising a drum mounted on a rotatable shaft, a said cleaning mechanism being in driven engagement with a said rotatable shaft of said central unit, the rotary shafts of said drums of the respective units being in line with one another and driveably interconnected by means of telescopic shafts and universal couplings.
A harvester machine for attachment to a tractor comprising a plurality of harvester units, said units being interconnected and having common coupling means at the rear of said machine connectable to a three-point lifting hitch extending from the front of said tractor with respect to the normal direction of travel, a container attached at the rear of the tractor wherein a delivery device is positioned to receive processed crop from at least one harvester unit, said device having an outlet extending over the tractor to its rear and opening out above said container, said units being positioned side-by-side transverse to the direction of travel and in front of the tractor during harvesting operations, further coupling means provided on the machine adjacent one side thereof, said units being connectable by said further coupling means to the tractor and being interconnected whereby they are aligned to trail the tractor one after another in a transport position.
