A powerful air-cooled engine with EFI technology delivers a responsive, fuel efficient performance. This mower provides powerful acceleration and throttle response. Built-in diagnostics and service light on the instrument panel simplify troubleshooting.

Powered 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.

This higher horsepower, new-generation version of the Model B adds a Kohler 26.5 HP, EFI engine and includes a redesigned unitized chassis and front body. The new clamshell body makes drivetrain component access easier, and the Ogura electric clutch with Soft Start adds convenience and durability for the operator. An oversized Donaldson 5 inch air filter is fitted with a turbine-style pre-cleaner and restriction gauge to reduce maintenance intervals while providing a robust filtration system.  A new rear axle design improves rough condition handling, coupled with Walker’s Comfort Seat and optional 20” drive tires, make the B27i a comfortable machine that is powerful, efficient, and ready for larger decks and difficult conditions. With numerous deck sizes and styles, optional LED Lights, Suspension Seat, Big Tire Kit, and Utility Dump Bed, the Model B is customizable to meet the needs of the most demanding customers.
