All The Power Is Right At Your Fingertips

Brake, engage, electric blade start and control levers are just a grip away. Also has a unique central neutral lock, locking both transmissions in a single action, that works with either hand. An exclusive feature found only on a Bad Boy Walk-Behind!

Fueled To The Brim

Larger 5 Gallon fuel tank for long running operation. Features an easy-to-check fuel gauge.

Rider Present Switch For Safety

No other walk-behind in the industry has the ease of use of our single lever rider present switch.

Larger Wheel Size And Why It Matters

Our front and rear tires are larger than any other Walk-Behind in this class for better traction and stability.

Manual Pin Height Adjustment

Lock into a consistent cut height with our pull pin system. Handles on deck assist in holding deck in place while making adjustments.

More Power Provided By Hydro-Gear

Our Walk-Behind's Hydro-Gear® ZT3100s are the largest in their class for durable power and performance. Protected by skid plates from curbs or other obstructions.

Our Optional Sulky Is So Unique, Its Patent Is Pending

For easy hop-on ride-ability and smooth ride, our Sulky features our exclusive EZ-Ride Technology. Also available for other brand walk-behinds.
