Each collection deck has a two-blade design with timed gearboxes turning the blades in a counter-rotating direction (both blades moving toward the center of the deck from the front) or reverse rotation (blades moving forward and circulating material to the back of the deck for collection in the discharge chute) on "R" decks. Collection decks are compatible with Walker Grass Handling (GHS) models S, C, T, and D and are designed specifically to catch grass and debris.
Walker discharge decks are designed to cleanly and evenly discharge cut grass from under the deck housing. For models B, S, C, T and D, decks use timed gearbox decks with two, three or four blades, except for three belt-drive decks—S42B, S52, S62. Two decks are built specifically for the Model H; R52 and S60.
Walker mulching decks are designed to efficiently handle cut material and return it to the turf leaving a beautiful, clean cut. With deck sizes or kits ranging from 36 inches up to 52 inches for B, S, C, T, and D-series tractors, there is a mulching option to fit most needs. H-series tractors can also mulch when a 60-inch mulch kit is installed.
