Abstract: Spreaders are provided for distributing material. A spreader includes a hopper assembly defining a receiving area configured to hold the material, the hopper assembly comprising one or more dispersion outlets for releasing the material from the receiving area; a distribution element disposed below the one or more dispersion outlets; a frame supporting the hopper assembly; a handle assembly connected to the frame; a plurality of wheels operatively connected to the frame for traversing the spreader; and a drive assembly comprising a motor operable to drive one or more of the plurality of wheels, wherein the plurality of wheels can be manually rotated without being driven by the motor, and wherein rotation of the wheels causes the distribution element to rotate.

Abstract: An apparatus may include a tower configured to be mounted to a boat. The apparatus may further include an actuation assembly, wherein the actuation assembly may include a linkage extending between a folding portion of the tower and at least one respective base for moving the tower between a first position and a second position.

Abstract: A telescoping tower for a boat may include a center section of a tower. The apparatus may further include at least a first support and a second support each comprising a telescoping assembly, wherein the telescoping assembly may include two or more members longitudinally moveable relative to one another for moving the center section of the tower between at least a first position and a second position.

Abstract: A towing apparatus comprises a structural assembly extending between opposing first and second bases for pivoting between operating and stored positions. A locking assembly includes a pin in each base and a hook carried at opposing ends of the structural assembly. A cam is pivotally connected to the hook for movement between locked and released positions. In the locked position, the hook is secured to the pin for preventing rotation of the structural assembly. In the released position, the hook is spaced from the pin to permit rotation of the structural assembly. The hook is rotatable with the cam from the released position to adjacent the pin by rotation of a shaft and slidable along the pin into the locking position by a continued shaft rotation. A cable is attached between the base and a spring within the structural assembly for biasing the structural assembly toward the operating position.

Abstract: Submerged jet nozzles are located at equal distances from the center of a tank containing a quantity of liquid and solids. Some of the nozzles induce flow partly inward and some induce flow partly outward, but all mixers are directed generally in the same circumferential direction. The inward directed nozzles are located close to the bottom of the tank and direct liquid across the central portion of the tank where solids tend to accumulate. Upper nozzles direct flow at least partly outward but in the same circumferential direction as the lower nozzles. The flow from the upper nozzles tends to reflect off the wall of the tank in addition to inducing a rotational flow of substantially the entire body of liquid in the tank.
