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

Grasshopper True ZeroTurn maneuverability takes PTO-driven CleanSweep Rotary Brooms into places ordinary sweeper attachments can't go, speeding debris removal and snow removal in congested areas as well as long stretches of sidewalks, driveways and curbs, even outdoor hockey rinks.


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.
