A chute rotation system. The chute rotation system includes a chute, a handle assembly, and a drive assembly. The handle assembly includes a handle rotatable about a first axis and a second axis, and a bracket configured to inhibit movement of the handle about the first axis. The drive assembly is coupled to the handle assembly and includes a chute drive, a transverse gear, and a friction brake. The brake is configured to prevent movement of the chute, as a result of friction, when the friction brake is engaged with the chute drive.

A shear clutch assembly for a rotatably driven power transmitting shaft and including a shear bolt which is sheared and causes a disconnect in the driving parts for the shaft. The assembly includes a flange rigidly fixed to the shaft and a rotatably driven member, for example, such as a sprocket rotatably mounted on the shaft and connected to the flange by the shear bolt. A reversing drive mechanism is carried by the driver or the driven member and when the power is transmitted in the normal or forward direction, the reversible drive connection is ineffective. However, when the shear bolt means has been severed and dislodged, power can be reversed and this causes the reverse drive connection to become effective for driving in the reverse direction. In this manner, the power shaft can be easily reversed in its direction to clear the overloaded conditions which caused the shear bolt to fail and to effect the reversal of the power shaft, it is only necessary to reverse the direction of the power to the power driven sprocket. A machine, such as a harvester or other agricultural implement for example, is provided and which has a pair of cooperating power driven feed rolls for feeding material therethrough and the shear clutch assembly is incorporated in a power driven shaft for said feed rolls.
