The RYOBI 40V HP Brushless 21" Self-Propelled Multi-Blade Mower Kit, a lawn mower electric kit, delivers more power than a 170cc gas mower for homeowners doing lawn maintenance & yard work outdoors in spring and summer. The (2) included 40V 6Ah batteries provide up to 75 minutes of runtime for tackling up to 3/4 acre while utilizing two active battery ports, supporting cordless mowing, lawn cutting, and gas-free mowing as a primary lawn mower for residential users. This self-propelled electric mower features a 3-in-1 CROSS CUT multi-blade system for cleaner mulching, even side discharge, and efficient bagging with fewer changes. A brushless motor automatically adjusts power to handle thick grass without bogging down. SMART TREK variable speed matches your pace, while the CUT COMMAND CENTER lets you monitor runtime, control speed, and activate turbo mode and lights. One-touch folding handles allow quick, compact vertical storage. Additionally, the RYOBI 40V HP Brushless 2-Tool Combo Kit includes a 17" attachment-capable string trimmer, 800 CFM blower, 6Ah battery, & fast charger. 40V HP delivers strong power, long runtime, and durability with quiet, gas-like performance. The trimmer outpowers a 32cc gas model, runs over 65 minutes, & supports multiple attachments. The blower exceeds 31cc gas performance with 800 CFM/180 MPH & up to 60 minutes of runtime. Both tools are part of the WHISPER SERIES for significantly quieter operation, & the battery recharges in under 90 minutes.
