Features

Features

  • RIDE WITH EASE: The Revolt X's shorter frame and curved I-Beam front fork give you a lower center of gravity for maximum maneuverability and visibility. With its upgraded operator pad and fender mounted support steps no other stand-on mower can compete with this unbelievably smooth ride.
  • CONTROL IS IN YOUR HANDS: The one-touch hand operated height of cut control makes on-the-fly adjustments easy. You can quickly switch between the position speeds for smoother operation in the tightest of spaces, and stop on a dime thanks to the upgraded R-Series style brake.
  • TACKLE ANY TURF: The Revolt X features Michelin® X® Tweel® Turf Tires, providing better hillside traction and stability, with no flat tires, giving you the edge you need to get the job done no matter the terrain.
  • SELF-CONTAINED POWER: The Bad Boy Revolt X is driven by Hydro-Gear 16cc Pumps with 18 cubic inch Wheel Motors include a Cooling Fan on Pumps and Dual Independent 2.5 Quart Hydraulic Fluid Reservoirs, this hydraulic system is designed for performance and longevity. Paired with the Vanguard 40HP EFI and Kawasaki 38.5HP FX1000 EFI Power plants, the Revolt X runs cleaner and cooler for better performance and life expectancy. As for innovative features, you'll love the variable deck lift adjustment. Now you can change the height of cut with just one touch, giving you the power to make on-the-fly adjustments quickly and easily. Revolt. Powerful performance in a smaller package.
  • THE BAD BOY LEGACY: Built on the legacy of classic Bad Boy Mower performance and strength, the Bad Boy Revolt X Stand-On Zero-Turn Mower takes everything you love about our Revolt mower, and dials it up a notch. It's proudly made at our Batesville, Arkansas headquarters using a heavy-gauge, all-steel, all-welded and fabricated 1.5˝ x 3˝ frame rail that's built to last a lifetime. Available in 54”, 60” and 72” deck options, all are made with all-welded steel, giving you unmatched strength.
  • BUILT RIGHT FROM DAY ONE: We pack more in our zero-turn mowers so you can get more out of them. Every Bad Boy Mower shares the same heavy-duty, last-a-lifetime construction. Our reputation rests on our all-steel "heavier-duty than they have to be" cut and welded rails. And before any mower leaves our plant, we give it a spin for quality first with our 112-point factory inspection. It takes longer to build a mower like ours than to stamp one out, but it's the only way to guarantee that we won't just out-mow the competition, we'll outlast it as well.
  • REVOLT X UPGRADES: If speed is what you need, you’re going to love the Revolt X Stand-On Mower. Our newest addition to the Bad Boy Lineup has been fully upgraded. With Standard run flat front tires and Michelin® Tweels rear tires with renowned run-flat technology, these tires come with a revolutionary rear tread pattern that grips like a glove, so you can confidently mow any terrain. This mower also includes a striping kit, increased fuel capacity to 13 gallons, and upgraded drive system. If you want to mow with an attitude, these innovations continue to change the game.
