Abstract: A telescoping rotatable tool includes a first shaft and a second shaft. The first shaft has a first material-engaging element extending from an exterior surface of the first shaft. The second shaft has a second material-engaging element extending from an exterior surface of the second shaft. The second shaft is configured to extend from and retract within an interior space presented by the first shaft. The first shaft includes at least one helical-shaped groove extending along an interior surface of the first shaft. The second shaft includes at least one guide element extending from the exterior surface of the second shaft. The guide element is configured to engage with the groove, such that as the second shaft extends from and retracts within the first shaft, the second shaft is configured to rotate with respect to the first shaft.

Abstract: A material dispensing vehicle broadly includes a material hopper supported by the vehicle and a swing auger with inlet and outlet ends. The swing auger is coupled to the vehicle for shifting into and out of an extended operating position where the inlet end is disposed to receive material from a discharge opening of the hopper and the outlet end can be outboard of the vehicle. From the operating position, the swing auger is shiftable into a compact storage position where the inlet end is spaced from the discharge opening and the outlet end is inboard of its outboard position.
