Good question. All three new GrandStand models, 36", 40" and 60" utilize existing/proven TURBO FORCE decks. The 36" and 40" TURBO FORCE decks have been used on Toro mid-size walk-behinds for four (4) years, while the 60" TURBO FORCE is the same deck used on our Z Master zero-turn riders since 2003. The only real differences are in how the decks physically mount-up to the GrandStand, and the fact there is no belt misalignment with GrandStands because the deck and engine/crankshaft move together when cutting height is adjusted.
