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 roll angle facilitates correction of the lateral motion induced position errors resultant from motion of the antennae as the vehicle moves based on an offset to ground and the roll angle. Alternative aspects include multiple-antenna GNSS guidance methods for high-dynamic roll compensation, real-time kinematic (RTK) using single-frequency (L1) receivers, fixed and moving baselines between antennas, multi-position GNSS tail guidance (“breadcrumb following”) for crosstrack error correction, guiding multiple vehicles and pieces of equipment relative to each other, and snow grooming equipment and method applications.

A system and method for controlling access to a work vehicle includes limiting an unauthorized operator's access to the work vehicle by disabling an engine subsystem and additionally limiting access to another vehicle system such as an auxiliary fluid actuator, by disabling at least one of the auxiliary fluid actuators. In this manner, even if a thief hot wires the engine of the work vehicle, he will not be able to use the work vehicle since the engine and the fluid actuators and the fluid controller that controls the actuators are independently disabled.

This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15). We protect homeowners, their cars and their plows from injury when plows strike hidden objects. Protection devices comprise safety springs (60) and pivots (63, 67 and 69) of FIG. 3B, the tension-release mechanism mentioned but not detailed in FIG. 15, annor shields (396, 398) of FIG. 16 and various others mentioned or provided for in our drawings but not detailed. We prefer cars' chassis tie-down ears (72) in FIG. 3A, as connector points for our plow or thrower arms. For cars lacking such ears, we propose add-on ears. For example, tie-down ear (126) in FIG. 6.

A snow removal apparatus in the form of a shovel in which a leveraged arrangement is used to lift snow gathered on the shovel blade by lateral movement of such blade while supported by a handle adjustably secured upon the blade and the shovel handle is rested upon an underlying surface while snow is being lifted and moved to a dumping area by leveraged foot movement upon a pivot arm pivoted upon the handle and attached to the blade thus avoiding strain on a shovelers arms and spine while shoveling.

In a structure of an engine compartment in a work machine such as a tractor, a bulldozer, a hydraulic excavator, a wheel loader, the air taken through vents, which are formed on side covers and a hood covering the engine compartment, is supplied directly to a radiator via ducts which are provided on the side of the side covers and the side of the hood respectively. The ducts cover the vents, thereby preventing noise within the engine compartment from escaping to the outside. Therefore it is possible to increase a cooling efficiency of the radiator by supplying the outside air, which does not take up the heat of an engine, directly to the radiator, as well as to reduce the engine sound and prevent the engine noise from escaping.
