Publication number: 20010047600Abstract: A plow support assembly provides support of a plow assembly when the plow assembly is disconnected from a vehicle. The support assembly includes a support foot and is operable to move the support foot to a lowered, support position whereby the support foot engages the ground or support surface. The support assembly includes a control device which is operable to limit the downward movement of the support foot in response to a signal indicative of the support foot engaging the support surface, such that movement of the support foot is stopped once the support foot contacts a support surface or ground. The signal may be provided by a switch which is operable to communicate the signal in response to detection of a threshold position of the support foot, engagement of the support foot with the support surface, or a threshold hydraulic fluid pressure within the actuator, respectively.Type: ApplicationFiled: July 11, 2001Publication date: December 6, 2001Inventors: Philip J.

Patent number: 6286236Abstract: An attachment adapted to be coupled with a zero turning radius prime mover is provided. This attachment includes a tongue adapted to be received by the zero turning radius prime mover, a mounting tab coupled with the tongue, and an implement coupled with the tongue. A first electric cylinder coupled with the prime mover is also coupled with the mounting tab and is able to move the tongue and implement up and down. This first cylinder also provides a downward force on the tongue and implement when it is in a lowered position. Still further, a second electric cylinder is coupled with the tongue for moving the implement from side to side or up and down. The implement may be any useful attachment such as a blade, a bucket, or a broom. In the preferred embodiment, the tab is comprised of a first bracket member rigidly coupled with the tongue and a second bracket member coupled with the first bracket member. The first electric cylinder is coupled with the second bracket member.Type: GrantFiled: September 22, 1999Date of Patent: September 11, 2001Assignee: Bowers Designs Inc.Inventor: Troy S. Bowers

Patent number: 6276076Abstract: A hitch assembly provides removable connection of a plow assembly to a push beam assembly installed on a vehicle. The hitch assembly includes a draw latch assembly which engages the push beam assembly and pulls the plow assembly into position for pivotal attachment of the plow assembly to the vehicle. The draw latch assembly is activated by a power source, such as an hydraulic cylinder, and is further interconnected with a lift arm assembly such that further extension or activation of the hydraulic cylinder results in a raising or lowering of the plow blade. Also included is an easy connection and release mechanism for inserting and retracting pivot pins through corresponding brackets on the lift arm assembly and push beam assembly. A light tower assembly is removably attached to the push beam assembly such that when the plow is not in use, only the push beam assembly and its mounting brackets remain on the vehicle in a position below and rearward of a front bumper of the vehicle.Type: GrantFiled: November 3, 2000Date of Patent: August 21, 2001Assignee: Blizzard CorporationInventors: Philip J. Quenzi, Cal G. Niemela

Patent number: 6240659Abstract: Control system for a jack for raising and lowering a lift assembly for hydraulically driven snow blades or other utilitarian accessories. Actuation of the jack allows for proper vertical alignment of the lift assembly for engagement to a vehicle chassis. Once engaged, the jack can be actuated into an inoperative position until the lift assembly is to be removed from the chassis. The control system includes several safety features that prevent the jack from being deployed when the snow blade is raised, and that automatically retract the jack when the snow blade is raised.Type: GrantFiled: May 21, 1999Date of Patent: June 5, 2001Assignee: Curtis International, Inc.Inventors: Marc D. Curtis, Gary Harris

Patent number: 6151809Abstract: The snowplow of the present invention is adapted to mount to the bed of a pickup truck. The snowplow includes a mounting base and a frame which is rotatably coupled to the base. The snowplow blade is coupled to the frame so that it moves with the frame. By attaching a hydraulic system to the frame and base, the blade can be raised and lowered over a very wide range. The frame and blade are adjustable so that the same snowplow can be used on trucks with differing heights or with lift kits.An alternative embodiment, the frame of the snowplow is mounted to the ends of the cross bar of the vehicle hitch. Hydraulic cylinders move the frame assembly and blade between raised and lowered positions. A conventional spreader may be mounted to the central receiver of the hitch so as to be positioned between the spaced apart arms of the frame assembly. In both embodiments, trip action springs are provided such that the blade is normally biased to an upright snow removing position but will pivot to override obstacles.Type: GrantFiled: December 30, 1998Date of Patent: November 28, 2000Inventor: Edward Altheide
