20100269377 | STABILIZED FLOAT MECHANISM FOR MATERIAL-MOVING IMPLEMENT - A float mechanism for movably attaching an implement to a vehicle has a mounting frame that connects onto the vehicle and a fixed frame that affixes to the implement. A pivot bracket pivotally attaches to one of the frames and is slidably connected to the other to accommodate a limited degree of translational motion. The pivot bracket can slidably connect to the frame by a pair of guides in combination with a pair of sleeves. Rotational motion between the fixed frame and the mounting frame can be limited by slots in one of the frames that are slidably engaged by a stabilizing element on the other frame. When the stabilizing element is a horizontal bar, it can engage a pair of vertical slots. To optionally eliminate the free motion between the frames, movable blocks can be employed to limit the motion of each stabilizing element in its slot. | 10-28-2010 |
20120285050 | Quick-Connect Plow Hitch - The front mounting assembly has a vehicle-mounted frame and a plow-mounted frame that are drawn together by a lift actuator such as a hydraulic cylinder, and brought into registry by guides.

A lift arm is pivotably mounted to the slider and is raised and lowered by a pivot actuator connected between the slider and the lift arm. When lowered, the lift arm can be positioned such that it engages and raises the mounting block when the lift arm is pivoted back to its raised position. The engagement allows the lift arm to carry the mounting block with it when the slider is retracted, drawing the mounting block into a bracket on the base element to which the mounting block can be secured. | 09-11-2014 |
