Operator enclosure for an agricultural tractor

An operator enclosure for an agricultural tractor has a rollover protective structure (ROPS) in which the front side of the ROPS (12) extends upward above the left, right and rear sides of the ROPS (12) and terminates at a front upper cross member (32) extending laterally between left and right front upright corner members (14, 16). A roof pan (48) is placed at the top of the ROPS (12) that has a generally horizontal top panel (50) at about the same height as the front upper cross member (32). The top panel (50) of the roof curves downward to form left, right and rear side panels (52, 54) extending downward from the top panel (50) to the height of the upper members (30) of the ROPS (12) along the left, right and rear sides. There is no front panel on the roof extending downward from the top panel (50). The windshield (40) is extended upward into what had previously been the front panel of the roof. This improves the front upward visibility, an feature particularly useful in operating a front end loader on the tractor.
