Model B27i

A simplified design with improved performance

B27i Model Overview

๐’‰ฐThis 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.

๐”‰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 Walkerโ€™s Comfort Seat and optional 20โ€ drive tires, make the B27i a comfortable machine that is powerful, efficient, and ready for larger decks and difficult conditions.
