Abstract: A windrower has a hydrostatic header drive system with a header drive pump and one or more header drive motors. The windrower also has a chassis with wheels coupled thereto, an engine, and a ground drive system coupled to the wheels and the engine. A control system has plural sensors having first, second, and third sensors, wherein the first sensor monitors engine load, the second sensor monitors hydrostatic header drive pressure, and the third sensor monitors ground speed. The control system has one or more controllers configured to receive input from the plural sensors, compare the input with respective target values for engine load, header drive pressure, and ground speed throughout a range of ground speeds defined based on an operator configured maximum ground speed, and automatically adjust the ground speed based on the comparison.

Abstract: A toe-piece for binding a boot to a gliding board, the toe-piece including a first front boot-retaining device and a second front boot-retaining device. The first front boot-retaining device is designed for ascending a slope and includes boot-fastening mechanisms defining a hinge axis about which the boot pivots when the toe-piece is in an ascent configuration. The second front boot-retaining device is designed for descending a slope and includes two wings each supporting a lateral interface surface designed to come into contact with a front portion of the boot when the toe-piece is in a descent configuration. The toe-piece also includes a longitudinal stop surface movable between an active position in which it is designed to cooperate with the front portion of the boot, and an inactive position in which it is arranged so that it is no longer capable of cooperating with the front portion of the boot. The longitudinal stop surface is movable in relation to the wings.

Abstract: A method for determining when a cooling system for a work vehicle is restricted with debris. A first temperature difference between an inlet and an outlet of a heat exchanger is determined when the airflow though said heat exchanger is substantially unrestricted. When a subsequent temperature difference is less than the first temperature difference by a predetermined amount, the direction of the airflow is reversed to remove debris from the heat exchanger.

Abstract: A gliding apparatus includes a gliding board, a first front boot-retaining device for ascending a slope and a second front boot-retaining device for the descent. The first front retaining device comprises a first boot-fastening mechanism, defining a boot pivot axis during the ascent. The second front retaining device comprises a second boot-fastening mechanism, including a movable element incorporating an interface surface capable of contacting a front portion of the boot, the movable element being separate from the first fastening mechanism. The second front retaining device is configurable in a first “inactive” configuration for which the interface surface is away from the boot front portion, and a second “active” configuration for which the interface surface contacts the boot front portion. The first boot-fastening mechanism is capable of cooperating with the movable element of the second front retaining device so as to maintain the second front retaining device in its active configuration.

Abstract: A controller and method for operating an air mover for a cooling system of a work vehicle. In one embodiment, engine coolant, hydraulic oil and charge air temperature data is measured. The temperature data is reconciled by using the largest required fan speed as the set point speed for cooling the heat exchangers with airflow. An air mover is operated at the set point speed to generate airflow across each of the heat exchangers.

In one embodiment, the largest required fan speed for cooling the engine coolant, hydraulic oil and the charge air is used as the set point speed for a fan. The fan is operated at the set point speed to generate airflow across each of the heat exchangers. Multiple conditions are evaluated for reversing the direction of the fan.

Abstract: The invention is directed to a binding for retaining a boot on a gliding board, such as a ski, which includes a retaining device, a lower abutment surface, and a vertical spacer. The retaining device supports an upper abutment surface adapted to be in contact with at least one upper surface of a front portion of the boot. The lower abutment surface is adapted to be in contact with at least a portion of the sole of the boot. The lower abutment surface is connected to the retaining device so as to define an engagement height for the boot corresponding to the difference in height between the upper abutment surface and the lower abutment surface. The vertical spacer is rigid and includes a predetermined adjustment height. The vertical spacer is arranged relative to the retaining device and the lower abutment surface, so that the adjustment height of the vertical spacer makes it possible to adjust the engagement height.
