  • Patent number: 9676271
    Abstract: A tractor has a front bonnet which houses an engine and a cooling arrangement, the cooling arrangement having a fan, a radiator, and a mounting plate. The bonnet has a hood and two opposing side parts. A grill is positioned at the front of the bonnet through which air passes and enters the cooling arrangement. An extended fan shroud has a lower part which extends from the bottom half of a fan ring in a forward direction and an upper part which extends rearwards from the upper half of the fan ring towards the radiator over the mounting plate. A flange extends from the lower part of the fan shroud diagonally along opposing sides of the upper part and across the upper part of the fan shroud. The flange has a sealing member. When the bonnet is closed and in contact with the sealing member, two air compartments are defined.

  • Patent number: 9554499
    Abstract: An agricultural vehicle has an implement connection hitch which is moveable relative to a rear axle of the vehicle. A system for controlling movement of the connection hitch is coupled with position sensors such as a GPS receiver. During turning maneuvers, the control system moves the hitch relative to the rear axle of the vehicle until it reaches an offset position such as to reduce the turning circle of the vehicle and a connected implement. The extent of offset may be determined automatically by the control system on identification of a connected implement.
