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.
