Abstract: The elastic drive belt system connects the belt directly to a drive shaft and driven pulley. The elastic drive belt has a plurality of longitudinal ribs on the traction side of the belt. The drive shaft has a plurality of grooves sized and arranged to receive and engage the longitudinal ribs on the belt to facility torque transfer and alignment. This system facilitates delivery of relatively high amounts of torque to the driven pulley using relatively low horsepower motors. In many applications, such as a sander, the elastic drive belt system eliminates the need to readjust the tension on the belt as it wears.

Abstract: A support structure for a divider of an agricultural corn head that includes a first tension member that is pivotally attached to a second tension member. A stop is provided which prevents the lines of tension of the first and second tension members from aligning. The tension assembly can therefore buckle upwards when an object underneath the support structure is struck. A lateral support for the divider is also provided with a clearance opening for the tension assembly. The divider can be rotated rearward into a transport or a service position and securely locked in place. A shipping position is provided in which the support structure can be rotated rearward by disconnecting the tension assembly.

Abstract: A row crop header includes a frame, a first shield, a first hinge mechanism pivotably coupling the first shield to the frame, a second shield and a second hinge mechanism pivotably coupling the second shield to the first shield. The first hinge mechanism includes a first female coupling member coupled to a first one of the first shield and the frame and a first male coupling member coupled to a second one of the first shield and the frame. The first male coupling member is rotatably received within the first female coupling member for pivotably coupling the first shield to the frame. The first male coupling member is removable from the first female coupling member upon selective rotation of the first male and first female coupling members relative to one another. The second hinge mechanism includes a second female coupling member coupled to one of the first shields and the second shield and a second male coupling member coupled to the other of the first shield and the second shield.
