  • Patent number: 7314342
    Abstract: The cement hopper attachment includes a raised hopper supported atop two uprights extending from a rectangular base. The hopper has a forward mounted gate and cement chute. A hydraulic cylinder operatively connected to the skid steer's auxiliary hydraulic controls actuates the gate of the hopper. The shape and configuration of the hopper is design to provide an unobstructed view from the skid steer of the cement dispensed from hopper. The hopper attachment also includes a pair of retractable support wheels, which support the weight of the loaded hopper attachment and prevent rocking and tipping forward under the weight of the loaded hopper attachment.
