Abstract: A feeding mechanism for a round hay baler is capable of feeding plastic sheet, netting, or alternatively twine by means of a single set of parallel feed rolls. The device includes a control mechanism which, upon sensing of a full bale having been formed within the baler, initiates a programmed control sequence beginning with driving of one roll for an incremental period of time. The driven roll engage netting, sheet or twine against the second idler roll and feeds the netting, sheet or twine into the bale forming mechanism for wrapping about the bale. Upon completion of the wrapping sequence, a special knife descends and cuts the twine or sheet of netting or plastic. The controller then resets the mechanism.

Abstract: A water brake dynamometer includes a water brake having a stator housing with a rotor disc mounted on a through shaft. Water from a reservoir is directed into the housing as the shaft and rotor are driven by an external engine. Means are provided to measure the torque transferred from the rotor to the stator housing. An adjustable, unitary valve mechanism controls the rate water is directed into the housing from the reservoir and removed from the housing for return to the reservoir. The valve mechanism includes a single stem having multiple valve members operated by a single hydraulic piston control.

Abstract: A water brake dynamometer includes a water brake having a stator housing with a rotor disc mounted on a through shaft. Water is pumped into the interior of the housing as the shaft and rotor are driven by an external engine. Momentum interaction transfers force between the rotor and stator housing. The planar surfaces of the opposing surfaces of the rotor housing are substantially identical as are those of the stator. A measuring device has been provided to measure the torque transferred from the rotor to the stator housing.
