Abstract: A low cost plow lift and down pressure system comprising a lift frame having a lift end and a mount end for securing to a plow vehicle. A push frame is pivotably coupled between a plow and the lift frame. A lever beam articulates with a lift end of the lift frame between a rear end and a forward end of the lever beam. The lever beam is able to perform a first function from the forward end and a second function from the rear end. An actuator, typically in the form of a hydraulic cylinder, is pivotably coupled at a forward end of the lever beam and an opposed end of the actuator is pivotably coupled to the lift frame. Activation of the actuator results in activating at least two functions of the system.

Abstract: A low cost plow lift and down pressure system comprising a lift frame having a lift end and a mount end for securing to a plow vehicle. A lever beam articulates with a lift end of the lift frame. The system further comprises a; lift tension line, down pressure tension line, hydraulic pump, hydraulic cylinder, push frame, down pressure arm, and plow. A push frame extends between a plow and a lift frame. A lift tension line extends between a plow receiver near the plow and a lift receiver on the lever beam. A down pressure tension line extends between a first down pressure receiver on the lever beam to a second down pressure receiver located on a down pressure arm that is coupled to the push frame. Active extension and retraction of a first hydraulic cylinder causes consequent raising of the plow and plow down pressure.

Abstract: A line belt driven retrofittable door opener includes a motor, a drive link, an output link, and at least one flexible link. The at least one flexible link includes at least one flexible line link. The drive link is connected to the motor. The output link is connected to the arm of the door. The at least one flexible link interconnects the drive link with the output link. Wherein, the motor is configured for opening the door by rotating the drive link, which in turn rotates the output link via the at least one flexible link, which in turn rotates the arm, thereby opening the door.
