Claim 9

A combine comprising a longitudinally extending frame structure, front and rear wheel means supporting the frame structure at its front and rear ends respectively, a crop receiving header mounted on the front end of the frame structure and extending forwardly of said front wheel means, engine mounting means supported by the rear end of said frame structure and extending rearwardly of said rear wheel means, a casing mounted on said frame structure, a threshing cylinder rotatably mounted in said casing at the upper front part thereof, means for delivering crop harvested by the header to said threshing cylinder, grain separating mechanism located in said casing beneath and rearwardly of said threshing cylinder, a grain collecting bin disposed between said front and rear wheel means and below said frame structure and located in its entirety beneath said grain separating mechanism, an engine for driving said threshing cylinder and said grain separating mechanism and supported by said engine mounting means at a point rearwardly of said rear wheel means whereby said rear positioned engine tends to balance the forwardly positioned header to increase the traction on said rear wheel means and the center of gravity of the combine is generally low and gets lower as the grain collecting bin becomes filled to provide increased lateral stability under load, said grain collecting bin extending laterally beyond the side walls of said casing, horizontal top plates extending between said frame structure and the side walls of said bin, a boom type grain delivery means comprising a first conveyor extending vertically from the bottom of said bin through one of said top plates, and a second conveyor communicating with said first conveyor near the upper end thereof and disposed at an angle thereto and mounted for swinging movement about a vertical axis whereby back and forth swinging movement of said second conveyor will distribute and grain as it is being deposited in a receptacle.

Claim 10

A combine comprising a longitudinally extending frame structure, front and rear wheel means suppoRting the frame structure at its front and rear ends respectively, a crop receiving header mounted on the front end of the frame structure and extending forwardly of said front wheel means, engine mounting means supported by the rear end of said frame structure and extending rearwardly of said rear wheel means, a casing mounted on said frame structure, a threshing cylinder rotatably mounted in said casing at the upper front part thereof, means for delivering crop harvested by the header to said threshing cylinder, grain separating mechanism located in said casing beneath and rearwardly of said threshing cylinder, a grain collecting bin disposed between said front and rear wheel means and below said frame structure and located in its entirety beneath said grain separating mechanism, an engine for driving said threshing cylinder and said grain separating mechanism and supported by said engine mounting means at a point rearwardly of said rear wheel means whereby said rear positioned engine tends to balance the forwardly positioned header to increase the traction on said rear wheel means and the center of gravity of the combine is generally low and gets lower as the grain collecting bin becomes filled to provide increased lateral stability under load, said casing having a hinged top wall located above said threshing cylinder providing access thereto, and the rear part of said casing being open at the top to provide access to said grain separating mechanism, a removable tarpaulin for covering said open top, said grain collecting bin extending laterally beyond the side walls of said casing, horizontal top plates extending between said frame structure and the side walls of said bin and forming a top wall for said laterally extended portions of said bin, the front part of one of said top plates providing a cat walk to permit access to said hinged top wall for opening same and inspecting said cylinder.
