Abstract: In one embodiment, a skid plate comprising an upper surface and an opposing ground engaging surface, the ground engaging surface comprising one or more optical windows flush or extending beyond a plane of the ground engaging surface, each of the optical windows comprising an optically transparent material.

Abstract: A chopper drum assembly for a forage harvester including a chopper drum housing, a shear bar, a shear bar holder and a wear plate assembly. The chopper drum housing includes a first part and a wear plate assembly support surface. The shear bar holder is pivotally connected at a first end to the first part of the chopper drum housing and fixedly connected to the shear bar at a second end. A first end of the wear plate assembly is pivotally connected to the second end of the shear bar holder adjacent the shear bar, and a second end of the wear plate assembly is supported by the wear plate assembly support surface wherein, the wear plate support surface is arranged to be inclined to the horizontal.

Abstract: One embodiment of the present invention relates to an insertion plate disposed on an external surface of a cannabis bucking machine configured to receive cannabis plants containing stems and buds. The insertion plate includes a top surface, a first angled surface, a second angled surface, and a bottom surface. One or more additional angled surfaces may also be included. The first angled surface includes a plurality of insertion recesses and the second angled surface includes a plurality of insertion channels. The insertion recesses and channels are substantially conically shaped to function as a funnel for receiving larger cannabis bunches. The unique correspondence between the angle of the surfaces and the shape of the recesses allows feeders to efficiently insert larger cannabis bunches and continue to feed as the bunches are levered down from the insertion recesses to the insertion channels.

Abstract: An agricultural harvester includes a straw hood having a hollow interior space for receiving material other than grain (MOG) from a threshing and separating system of the harvester and chaff from a cleaning system of the harvester. A drive system is provided for powering a straw chopper and a weed seed mill. The drive system includes a single belt positioned outside of the straw hood that is wound at least partially around (i) a straw chopper pulley that powers the straw chopper, (ii) a weed seed mill pulley that powers the weed seed mill, and (iii) a power take off shaft of the harvester that receives power from an engine or other power source of the harvester.
