037234000 | Including specific hydraulic control system to position implement | 10 |
20080222926 | SNOWPLOW WITH PIVOTING SIDEBLADES - The left and right sideblades are hinged to the mainblade about vertical axes, and can pivot each through 180°. The sideblades are rotated by means of left and right hydraulic rotary actuators. The actuator includes a piston formed with helical splines, which drive a rotor sleeve of the actuator to rotate in a single-plane-circle when the piston is driven axially. The journal bearings in the rotary actuator are supplemented by bearings provided in a coaxial lower hinge, which are of much greater journal capacity than the bearings in the rotary actuators. The lower hinge protects the hydraulic rotary actuator from shocks due to the sideblade impacting against a kerb. | 09-18-2008 |

20090038185 | Valve Switch Unit - A valve switch unit has a detector configured to detect an input, such as current, from a machine controller. The valve switch unit also has a switching circuit configured to switch control of the one or more valves an automatic controller to the machine controller if the input from the machine controller exceeds a predetermined threshold. When the current detected exceeds the predetermined threshold, the circuit switches control from the automatic controller to the machine controller. In a similar fashion, when the current falls below the predetermined threshold, the circuit switches control back to the automatic controller. | 02-12-2009 |
20090090032 | APPARATUS AND METHOD FOR MEASURING AND CONTROLLING THE ANGLE OF A SNOW PLOW BLADE - A plow blade assembly ( | 04-09-2009 |
20100101120 | Fluid Pressure Drive Unit and Snow Removal Unit - There is provided a fluid pressure drive unit that can fulfill a position holding function stably even when an external force acts during the time when the position is held, the unit being used, for example, for the right and left angle adjustment of a snow plow blade. There is provided a first excessive load relief valve | 04-29-2010 |
20100175282 | System for Controlling Actuation of a Snow Plow Blade Using the Turn Signal / High Beam Control Stalk - A system for controlling the operation of a snow plow blade mounted on a vehicle is disclosed that uses the turn signal/high beam control stalk mounted on the steering wheel of the vehicle to control a actuation of the snow plow blade mounted on the vehicle. The control system operates in two alternately selectable modes, one of which allows the turn signal/high beam control stalk to be used to operate the turn signals and high beams of the vehicle, and the other of which allows the turn signal/high beam control stalk to be used to raise, lower, and pivot the snow plow blade. The control system may be switched between the two modes by initiating one of two respective sequences of actuation of one or more electrical switches in the vehicle. | 07-15-2010 |
20140068975 | WING PLOW POST - A wing plow post and method of manufacturing the post is disclosed. The post is intended for attaching a wing plow to vehicle for moving material, such as snow. The links of the post are parallel to the angle of the wing plow when the plow is in the plowing position to minimize stress on the post and frame of the vehicle. The post includes a float collar on the hydraulic lift cylinder to provide free floating of the toe end of the wing plow. It allows a wing plow to move over road surfaces and limit the stress on both the post itself and the frame of the vehicle to which the post is attached. Further, the present invention also allows power to be provided by a hydraulic cylinder in the downward direction to the toe end of the wing plow. | 03-13-2014 |

20150107134 | SNOW PLOW - A snow plow includes a control unit for controlling a raising/lowering drive mechanism so that an auger housing becomes horizontal, a relative angle detection unit for detecting the angle of the auger housing relative to a travel frame, and a horizontal detection unit for detecting the horizontal state of the auger housing. The control unit stops the raising/lowering drive mechanism when the control unit assess that either a first condition or a second condition is satisfied, the first condition being that the relative angle be zero and the second condition being that the auger housing be horizontal. | 04-23-2015 |
20150107135 | SNOW PLOW - A snow plow including a control unit for controlling the raising and lowering of an auger housing, a reset switch that can be operated by a worker, and a reset display light that illuminates in conjunction with the turning on of the reset switch. The control unit automatically raises and lowers the auger housing in accordance with the reverse and forward traveling of travel device, and automatically adjusts the auger housing to a horizontal position during forward travel of the travel device upon receiving an on signal from the reset switch. The control unit maintains the illuminated state of the illuminated reset display light according to the turning on of the reset switch, even when the travel device is traveling in reverse, and extinguishes the reset display light upon receiving a termination signal for terminating snow plowing work performed with an auger. | 04-23-2015 |
