Abstract: An agricultural vehicle including a chassis and a rechargeable high voltage DC electric battery, the chassis incorporating an intermediate frame and an encapsulated power electronics unit located within the intermediate frame. Since the power electronics unit is separated from the electric battery, this allows for ready repair and/or replacement of the battery over the lifetime of the vehicle.

Abstract: A cooling unit for an agricultural vehicle has a grid for allowing air to enter the unit while limiting debris and a heat exchanger for transferring heat from a coolant to air passing across the heat exchanger. The cooling unit further has a duct with motor driven fan, and a controller to monitor fan current and operate the fan in alternating directions. The controller generates a heat exchanger blockage warning when desirable fan current thresholds are not achieved.

Abstract: A cooling unit for an agricultural vehicle, the cooling unit including: a grid for allowing air to enter the unit whilst limiting the ingress of debris into the unit, a heat exchanger for transferring heat from a coolant carried within the heat exchanger to air passing across the heat exchanger, a duct situated between the grid and the heat exchanger, a fan situated in the duct, the fan driven by a motor to move air along the duct and across the heat exchanger, a controller in communication with the motor to monitor the current drawn by the motor, wherein the fan is operable by the controller in a first direction to draw air through the grid and across the heat exchanger and in a second direction for a predetermined period of time upon the current drawn by the motor rising above a first predetermined value, and wherein the controller generates a heat exchanger blockage warning in the event that the motor current fails to drop below a second predetermined value upon the subsequent rotation of the fan in the fi
