| 172663000 | WITH ACTUATOR | 20 |
| 20110303426 | PLOW ROTATION ACTUATOR - Describes a snow and debris removal system containing both lift and rotational actuators. The actuators allow for both up and down and rotational movement relative to the implement mounting device the removal system is attached to. The rotational movement is provided by a rotation actuator fixed to a frame which applies force to a cable via a worm. The cable is mounted to an implement causing the implement to rotate about a pivot point attached to the frame. Rotational forces incurred on the implement go from the cable to the nut to the worm which does not back-drive thereby, avoiding damage to the motor actuator. Up and down movement is provided by an actuator that is mounted to the frame of the debris removal system which drives a rack which is attached to a fixed point on the implement mounting device. | 12-15-2011 |

The apparatus includes a tether attached to a rearward frame member of the implement frame, and attached to the floating hitch assembly forward of the hitch pivot axis such that the tether extends under a forward frame member of the implement frame and under the hitch pivot axis. A bias element exerts a main bias force on the tether to put the tether in tension drawing the floating hitch assembly toward the rearward frame member such that a downward bias force is exerted on the floating hitch assembly and a downward bias force is exerted on the rear frame member, and such that an upward bias force is exerted at the hitch pivot axis. | 12-29-2011 |
