  • 40V HP Technology Delivers More Power Than a 163cc Gas Mower
  • Create Clean, Professional Looking Stripes & Patterns
  • Over 85 RYOBI 40V Products – All Work With Any RYOBI 40V Battery
The RYOBI 40V HP Brushless 21" Self-Propelled Mower Kit provides more power than a 163cc gas mower, offering a true gas replacement. With (2) 40V 6Ah batteries, you get up to 80 minutes of runtime, ideal for tackling up to 3/4 acre using two active battery ports. The brushless motor adapts to mowing conditions, boosting blade speed to prevent bogging down and powering through tough cuts. Its self-propelled rear-wheel drive ensures an effortless, efficient mowing experience. The CUT COMMAND CENTER allows you to monitor runtime, blade life, and adjust self-propelled speed, and features turbo mode for extra power. The 21" composite deck is lightweight, corrosion-resistant, and backed by a lifetime warranty. After use, the handles fold for easy vertical storage. As part of the RYOBI 40V system, it is compatible with all 40V batteries. This mower comes with a 5-Year Tool Warranty and a 3-Year Battery Warranty. Included are the RY40HPLM01 40V HP Mower, (2) OP40605 6Ah Batteries, OP406 40V Charger, Grass Catcher, Start Key, Side Discharge Chute, and Manuals. Additionally, complement it with the RYOBI 20" - 21" Lawn Mower Striper for professional-looking stripes. It's easy to install and use, with a funnel to fill it with sand or water (up to 25 lbs). Compatible with RYOBI 20" & 21" mowers, the striper includes the striper, funnel, and manual.
