Depending on who you ask, winter is great (kids and snowmobilers), or it’s the worst (the rest of us). The WORX 20” – 40V Snow Thrower makes a difficult chore easier on those of us who get grumbly when we need to blow out the driveway. It’s lighter and easier to use than traditional gas blowers, yet has enough power to clear out a 20” wide path of snow with each pass, that’s 10” deep, and blow it 20 feet away. Its single-stage rotary auger is more reliable and lasts longer because it’s just one piece, and the brushless high-efficiency motor wastes less energy, which extends the life of the blower while improving performance. The chute rotates 180°, and the chute deflector is easily adjustable, so you can blow snow where you’d like it to go. It comes equipped with long-lasting, bright, LED headlights, for working after dark. And the handle collapses for easy storage or transport. The grip was made to be comfortable, too, for when you’re going to be at it for a while. This comes with two 20V 4.0Ah batteries to give you 40V of rechargeable power, and a 4-amp Dual-Charger so you can be as ready as you’ll ever be for that next snowstorm.
  • 40V OF POWER & PERFORMANCE - Two Power Share batteries provide this snowblower with gas-like power, without all the drawbacks of using gasoline
  • SINGLE-STAGE ROTARY AUGER - Gives it the force to grind through compacted snow and ice like larger blowers, but in a smaller, maneuverable design
  • SAME BATTERY, EXPANDABLE POWER - Worx Power Share is compatible with all Worx 20v and 40v tools, outdoor power and lifestyle products
  • HIGH-EFFICIENCY BRUSHLESS MOTOR - Generates more power yet uses less battery than motors based on a brush design—it has a longer lifespan, too
  • 180° ROTATING CHUTE - Throw your snow up to 20 feet in any direction you choose, and the one-touch multi-position adjustable chute deflector gives you even better aim
  • DUAL LED HEADLIGHTS - So if you’ve got to clear the driveway before the sun is up so you can get to work, you’ll still be able to see what you’re doing
  • FULLY-COLLAPSIBLE HANDLE - Makes it easy to store during the off-season, and the soft-grip handle makes it easy to use and control during the on-season
Introducing the newest innovation in lawn mowers; the 21” Select Cut™ Lawn Mower with Touch Drive Technology™ Engineered to run two blades simultaneously, the EGO Select Cut Lawn mower is the 1st cordless lawn mower to have a multi-blade cutting system. Equipped with interchangeable lower blades; the EDGE Premium Mulching Blade and the EDGE Tri-Cut Blade. The Premium Mulching Blade is a fantastic blade for weekly mowing and gives you the run time and cut quality you expect from a high-end lawn mower. The Tri-Cut Blade is a heavy-duty blade that turns grass into fine fragments. The EGO Edge Upper Blade is the 2nd part of the multi-blade system. This blade slices the grass the lower blade sucks up to enhance the cutting performance. The EGO Select Cut Multi-Blade System is EGO’s solution to replacing premium gas lawn mowers for good. With clean white paper design thinking, Self-Propelled Touch Drive Technology came to life. Touch Drive Technology gives you all the drive control at the palm of your hands.

Effortlessly navigate tall grass and tough terrain with the ball bearing wheels. Easily adjust your deck height between 7 different height settings 1.5” – 4.5”.
