Model MH37i

Walker MH37iPowered by a 993cc big block Vanguard EFI engine, the H37i is a powerful and efficient machine for the professional user. Its engine, with high capacity air cooling system, big 5 inch diameter Donaldson air cleaner, Grammer suspension seat, and fully articulating decks means the H37i can mow complex properties easier, in harsh conditions, longer. And with the optional Model H Power Tilt-Up deck, maintenance and storage are even easier.
