  • Patent number: 9938689
    Abstract: A coordinated control method and system for a work vehicle having a primary implement and a secondary implement and one or more controllers. The controller(s) receive a primary implement position input, which is used to generate a primary implement control command to drive one or more primary actuators to position the primary implement. The controller(s) generate a secondary implement control command that is coordinated with the primary implement position input to drive one or more secondary actuators to position the secondary implement in a relative orientation with respect to an orientation of the primary implement resulting from the primary implement control command.

  • Patent number: 9886038
    Abstract: A global navigation satellite sensor system (GNSS) and gyroscope control system for vehicle steering control comprising a GNSS receiver and antennas at a fixed spacing to determine a vehicle position, velocity and at least one of a heading angle, a pitch angle and a roll angle based on carrier phase position differences. The system also includes a control system configured to receive the vehicle position, heading, and at least one of roll and pitch, and configured to generate a steering command to a vehicle steering system. The system includes gyroscopes for determining system attitude change with respect to multiple axes for integrating with GNSS-derived positioning information to determine vehicle position, velocity, rate-of-turn, attitude and other operating characteristics. Relative orientations and attitudes between motive and working components can be determined using optical sensors and cameras. The system can also be used to guide multiple vehicles in relation to each other.

A receiver is mounted on a support mount for maintaining an ice resurfacing machine level with a desired horizontal plane comprising a mast post that retracts within a structure mounted on the conditioner. The receiver detects a light beam being transmitted along a plane parallel to a desired horizontal plane. The position of the mast post relative to the structure is constrained such that the height of the receiver in a transport position is vertically retracted to permit the ice resurfacing machine to pass under obstacles while entering or leaving an ice surface and in an operative position is extended to a height whereby a light beam emitted by a transmitter along a plane parallel to the desired horizontal plane may be detected. At all times the mast post remains away from contact with the ice surface.

    Abstract: An ice resurfacing machine for small and medium-size indoor and outdoor ice skating rinks comprises a light towing vehicle, a resurfacing attachment, and a lifting and leveling assembly connecting them. To eliminate ruts in the ice, the machine removes only a thin layer of ice by scraping, fills the ruts with “snow” created by the scraping, skating, and precipitation, and adds water to fill the rut. The cold from the base ice and/or the atmosphere freezes the water and thus eliminates the rut. The machine may also be used to remove heavy snow or reduce the thickness of the ice. The resurfacing attachment includes a snow box which collects the snow and carries it along the surface of the ice.

  • Patent number: 7380355
    Abstract: A manually propelled ice rink building and resurfacing device. The device includes a chassis with removable wheels, a water tank mounted on the chassis, and a heating chamber within the water tank, the water tank receiving snow to be melted, the heating chamber in heat exchange relation to the water tank. Fluid dispensing means connected to the tank uniformly distributes, and evenly spreads a layer of water onto an ice rink surface. The device may be rolled on ice, dragged on snow, or stored in a vertical position.

  • Patent number: 7364240
    Abstract: An ice resurfacing machine for small and medium-size indoor and outdoor ice skating rinks comprises a light towing vehicle, a resurfacing attachment, and a lifting and leveling assembly connecting them. To eliminate ruts in the ice, the machine removes only a thin layer of ice by scraping, fills the ruts with “snow” created by the scraping, skating, and precipitation, and adds water to fill the rut. The cold from the base ice and/or the atmosphere freezes the water and thus eliminates the rut. The machine may also be used to remove heavy snow or reduce the thickness of the ice.

  • Publication number: 20080066349
    Abstract: A collapsible snow groomer designed to be provided as a partial kit where the buyer purchases two runners separately. Along with the runners the kit comprises all materials necessary to assemble a snow groomer for use on personal snow trails. The collapsible snow grooming device of the present invention includes and comprises: a tubular front spreader, two L-angle cross blades, a square central joiner tube, four angle grooming blades and all required fasteners. All grooming hardware members are thus strategically attached to one edge of each runner and to each other at one edge, thereby allowing to flip the whole assembly over to drag it where grooming is not desired.

  • Publication number: 20070277402
    Abstract: An apparatus and method for resurfacing an ice surface. The apparatus includes a chassis and a reservoir for holding water to be dispensed via a dispensing tube in fluid communication with the reservoir. A scraper assembly attached to the chassis includes a scraper blade adapted to engage the ice surface. A first thrower is rotatably mounted to the chassis adjacent to the scraper blade and a second thrower is rotatably mounted to the chassis adjacent to the first thrower. A snow storage compartment has an opening adjacent the second rotating thrower. The first rotating thrower is adapted to deliver ice or snow accumulated by the blade to the second rotating thrower. The second rotating thrower then delivers the ice or snow to the snow storage compartment. A motor is coupled to the chassis and a drive linkage is coupled to the motor for rotatably driving the first and second throwers.

  • Patent number: 6948569
    Abstract: A device for removing material from a surface includes a blade, an auger positioned in close proximity to a front side of the blade and operably mounted on an axle for rotary motion relative to the blade whereby material accumulating at the front side of the blade during movement of the blade over the surface is transversely moved from the front side of the blade to a side of the device by the rotary motion of the auger, and a handle operably connected to the blade for directing the blade and the auger over the surface. The auger has a passage receiving the axle. The auger is preferably rotatable relative to the axle and the axle is preferably rotatable relative to the blade. Preferably, the auger is molded of plastic and the passage is free of a molding draft.

  • Patent number: 6779823
    Abstract: A vehicle with a self-contained cooling and heating capability and a tenting feature for sheltering and controlling the temperature at a given location. Warm air is directed out of a heat chamber through a telescopic tube arrangement which may be horizontally piovoted for improved heat direction. The tube arrangement may also be vertically tipped upwardly and downwardly to maximize directional control of heat output. Heat for melting snow may thereby be directed to specific locations. The tenting arrangement provides elevated and focused heating and little heat waste.
