3-in-1 single-lever discharge functions easily adjust between mulch, bag, and side discharge options with a single lever.
LED lights increases visibility for cutting in low-light environments.
Stand-up storage handle fully collapses to support vertical storage and save space.
Charge-level indicator provides quick updates on remaining battery power.
