A zero turning radius mower radiator mounting structure having inclined deflectors extending upwardly from the radiator. The inclined deflectors slide on a cross member extending horizontally across the roll over protection system if the mower is in a rollover position. The inclined deflectors push the radiator rearwardly from the roll over protection system and disengage the radiator from first and second pairs of isolators.

A cutting unit mounting device includes a ball through which a yoke extends laterally. The yoke is attached to the cutting unit, and the ball is pivotably mounted in a ball housing attached to a lift arm. A releasable lock pin engages and secures the ball within the ball housing in a mowing position or a service position. The ball housing has stops to limit the pivoting of the ball and yoke with respect to the ball housing. A releasable lock pin engages notches in the ball to engage and secure the ball in the mowing position or service position with respect to the ball housing.

A ball joint assembly for attaching a cutting unit to a yoke includes a two piece ball positioned around the yoke, and a ball housing attached to the end of a lift arm and mounted over the two piece ball and securing the two piece ball to the yoke. The ball housing may have stops limiting angular movement of the two piece ball and the yoke with respect to the ball housing.

A height of cut adjustment mechanism is provided for a rotary cutting deck mounted on a lift arm extending from a traction vehicle. The mechanism includes a front axle and a rear axle, at least one roller mounted on each axle, and a pair of height of cut arms extending from each axle to a pivot axis on the rotary cutting deck. A notch lock on each height of cut arm may be moved between a locked position in which the notch lock engages a notch plate at a desired cutting height, and an unlocked position in which the notch lock disengages the notch plate so that the height of cut arm can pivot with respect to the rotary cutting deck. A lever attached to each notch lock can be operated to move the notch lock between the locked and the unlocked positions.

A hood covers an internal combustion engine on the rear of a grass mowing machine. The hood has a top surface with a plurality of air intake openings recessed below the top surface, and an integral air duct. The integral air duct extends over the engine between the air intake openings and an air inlet side of the radiator and/or oil cooler adjacent the rear of the grass mowing machine. The air intake openings closest to the air inlet side of the radiator and/or oil cooler are dimensioned to limit the air intake velocity and prevent buildup of debris on screens or grilles over the openings.

An elongated air intake screen is provided for vehicles such as commercial mowers that operate in conditions having substantial airborne foreign materials that tend to clog the screen. The exterior surface of the screen is provided with intake openings throughout its 360 degree surface to draw air over a substantial area. It is located at the upper edge of the vehicle to separate it from the cutting decks and area where airborne grasses and similar foreign materials are encountered. Air drawn into the screen is used to cool the engine and hydraulic fluid heat exchangers and provide for engine combustion needs.

An air filtering enclosure for a vehicle to minimize the amount of debris entering the radiator of the vehicle is provided. The enclosure forms a shell having a set of interfitting interior and exterior members. Mounted with the interior member are clips designed to mate with a series of compatibly arranged brackets on the vehicle frame. Attached opposite the clips are handles which a user may grasp to easily install and remove the shell from a vehicle. Interior and exterior members form a frame which encases sheets of perforated screening to restrict the introduction of debris into the radiator. The shell is completed with a rubber seal enabling tight sealing of the enclosure to the vehicle on which it is attached.
