Abstract: A tensioner assembly for tensioning a belt including a moveable arm, a first tensioner pulley mounted to the moveable arm, and a second tensioner pulley mounted to the moveable arm. In a first position of the moveable arm corresponding to a forward drive configuration, the first tensioner pulley is positioned in contact with the belt while the second tensioner pulley is spaced apart from the belt. In a second position of the moveable arm corresponding to a reverse drive configuration, the second tensioner pulley is positioned in contact with the belt while the first tensioner pulley is spaced apart from the belt.

Abstract: A rotary dust screen for a cooling unit of an agricultural vehicle includes a frame having a ring shape, wherein a dust screen is mounted in the frame and wherein the frame includes a seal extending along the ring and comprising a lip adapted to abut, when the rotary dust screen is mounted on the cooling unit, against a housing of the cooling unit to prevent contaminants from entering the cooling unit at an edge of the dust screen, wherein the rotary dust screen further has a driving belt adapted to be driven by a rotary actuator to rotate the dust screen, wherein the driving belt engages with the rotary dust screen at an outer surface of the seal.
