AERA-vator™ Coreless Aerator
The PTO-driven AERA-vator⢠is a coreless lawn aerator for Grasshopper FrontMount⢠zero-turn mowers. Available in 40- and 60-inch models, front-mounted aerators help to aerate lawns, turf and compacted soil in hard-to-reach areas previously accessible only to walk-behind aerators. By eliminating unsightly cores left behind by plug and core aerators, the AERA-vator⢠completes aerating jobs easier and faster, reducing time and labor up to 75 percent.
Little Bully™ Dozer Blades
Multi-purpose Little Bully™ Dozer Blades capitalize on Grasshopper zero-turn maneuverability to deliver powerful performance moving dirt, maintaining gravel driveways and plowing and clearing snow from sidewalks and driveways. The blades attach in place of the out-front mower deck, providing easy operation and timesaving performance.
Edge-EZE™ Edger
The Edge-EZE⢠lawn edger maintains clean, sharp turf edges along sidewalks, roadways and driveways, eliminating time-consuming secondary trimming and reducing edging time up to 75 percent compared to hand-held string trimmers and walk-behind wheeled edgers.
Tine-Rake™ Dethatcher
Mounting to the front of any Grasshopper MidMount™ (200V Series or larger) or FrontMount™ mower, the 46- and 60-inch Tine-Rake™ Dethatchers use spring steel tines to create a unified raking motion that removes large amounts of thatch and surface aerates soil. Used with a PowerVac™ Collection System, you can dethatch and collect debris in one pass for time-saving rejuvenation.
CleanSweep™ Rotary Brooms
Shielded Sprayer
Double or even triple your spray crew's efficiency and enjoy faster application and greater coverage with a shielded sprayer for your Grasshopper zero-turn mower. Featuring aerodynamically designed shields and fully shielded curtains to deliver a fine-mist chemical spray, the shielded sprayer delivers on-target application every time. Four-nozzle spraying chambers provide uniform coverage, applying small droplets that "stick" to vegetation for more coverage per tank - up to 5.5 acres or 240,000 square feet - using less chemicals.
DriftBuster™ Snowthrowers
Combining zero-turn maneuverability with a snowthrower takes snow removal to a new level of productivity and comfort, easily replacing conventional walk-behind snowblowers and other snow removal attachments. Available in both 48- and 60-inch models, PTO-driven DriftBuster⢠Snowthrowers for Grasshopper FrontMount⢠zero-turn mowers deliver "no clog" performance, even in the deepest and heaviest wet snow.
Turbine Blower
By attaching a PTO-driven Turbine Blower in place of the out-front mower deck and rotating the blower nozzle a full 360 degrees, operators can precisely and effortlessly move even the largest debris pile while retaining Grasshopper True ZeroTurn™ maneuverability. Leaves, debris and even fallen branches don't stand a chance against the Turbine Blower's 150-mph air velocity.
V-Plow
A 60-inch V-Plow makes snow removal easier and less labor-intensive on long sidewalks and driveways, plowing through deep snow drifts effortlessly and clearing a 5-foot path. The V-Plow retains Grasshopper True ZeroTurn⢠maneuverability for no wasted motion, even in heavy, wet snow.
FrontMount™ PowerVac™ Collection Systems
With a PowerVac™ Collection System for your Grasshopper zero-turn mower, you're getting the most powerful, maneuverable and efficient leaf-collecting, grass-catching and debris-removing equipment available for turf. You'll get a professional, finished look every time you mow.

PowerFold® Electric Deck Lift
Standard on all FrontMount™ DuraMax® decks 48-inch and larger, PowerFold® is the zero-turn mower industry's first electric deck lift (introduced in 2004).
PowerFold® rotates the deck nearly 90 degrees to provide easy access to the underside of the deck for simplified maintenance and mulching package installation, plus space-saving portability and storage.
The feature also adjusts cutting height between 1.0 and 5.0 inches and controls deck lift functions using a single switch.
Warranty
- Commercial Use: 3-year unlimited hours; limited warranty covering parts and labor.
