  • Patent number: 10781864
    Abstract: A drive wheel clutch system for manually disengaging one or more drive wheels from their driveshafts. The drive wheel clutch system generally includes a driveshaft, a flange at one end of the driveshaft, and a flange-engaging member. The flange-engaging member and the flange may be generally disc shaped. The flange-engaging member is spring loaded and includes locking members that can extend through apertures in the flange to engage with locking apertures in the hub of a drive wheel. An operator can pull against spring bias and rotate a handle connected to the flange-engaging member to disengage the locking members from the flange and the hub, allowing the wheel to turn freely while the driveshaft remains stationary.

  • Patent number: 9132696
    Abstract: A tire manipulation system for efficiently manipulating the position of a tire. The tire manipulation system generally includes a mounting device for removable attachment to a tractor, a telescoping main support structure attached to the mounting device, a main actuator connected to the main support structure, a pivot axle rotatably connected to the main support structure, a support frame connected to the pivot axle, and a pair of telescoping supports each having an actuator and a gripping member for engaging a tire to be manipulated. The gripping members first engage the perimeter of a tire to be manipulated and then using the loader system of the tractor the user is able to manipulate the attitude of the tire.

  • Patent number: 8272493
    Abstract: A swing auger drive attachment system for remotely moving a swing auger in a circular arc. The auxiliary drive attachment generally includes one or more mounting brackets each having a plurality of openings, the openings adapted to align with preexisting wheel mounting holes of a swing hopper to vertically adjustably attach the mounting bracket. The mounting bracket also being horizontally angularly offset so an attached wheel is aligned with a curved directional path of the swing hopper. Connected to the mounting bracket is a drive motor having a drive shaft and a wheel connected, the wheel having a coupler assembly to rotationally connect and disconnect the wheel from the drive shaft to provide motor-driven power to the wheel or allow free-rotation of the wheel. A control unit in communication with the drive motor may be connected to a remote controller or an onboard manual controller.
