A cooling system for a work vehicle includes a fan rotating in a first direction to generate an air flow in a first direction, a speed sensor sensing a speed of the fan, one or more sensors sensing a load of a power source, a temperature sensor sensing an ambient temperature, and a controller configured to determine the load of the power source, determine the speed of the fan, determine an estimated speed of the fan based in part on the load of the power source and the ambient temperature, determine a speed difference of the speed of the fan and the estimated speed of the fan, and determine changing the air flow to a second direction based in part on the speed difference and the load of the power source.

A roof structure for an agricultural vehicle includes an upper roof assembly and a lower roof assembly connectable to the upper roof assembly. The lower roof assembly or the upper roof assembly includes a ventilation opening for guiding air-conditioned air and a circulation opening for supplying recirculated air. An air-guiding element is arranged between the lower and upper roof assembly. The air-guiding element is further disposed at the circulation opening and the ventilation opening such that a region sealed in relation to an external environment is formed.
