A triplex greensmower open foot platform provides an opening in front of an operator seat providing visibility from the operator seat to a center reel cutting unit. The opening has sufficient dimensions for removal or installation of the center reel cutting unit or a grass catcher therethrough. A pair of platform sections provides a perimeter at least partially around the opening. Each of the platform sections including a footrest and a rearwardly extending coupling that is manually removable from the triplex greensmower.

A mounting assembly to mount the base of a hydraulic motor on a mower deck includes a cast iron mounting plate having stiffening structures around the perimeter and spanning the perimeter, and rubber isolators between the mounting plate and the mower deck.

A shift mechanism for trim mower cutting units includes a pair of slidable carriers. Each slidable carrier can slide along a pair of guide rods mounted to a mower frame. A hydraulic extension cylinder is connected to each slidable carrier and independently extends to move the slidable carrier laterally outward from the mower frame or retracts to move the slidable carrier laterally inward in relation to the mower frame. A hydraulic shifting cylinder is mounted between the two extension cylinders and extends to shift both slidable carriers laterally inward toward a center position, and retracts to move both slidable carriers laterally outward toward an extended position.

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.
