Shipping weight includes packaging, charger and bag, so actual running weight w/o the bag is probably well under 70 pounds. It's $100 less than the 80 volt Kobalt and Greenworks, so it it seems to be the best value out there in a 21" steel deck Li-Ion lawn mower. As to the plastic Greenworks Twin Force mower, mine has started to fail at the connection of the handle to the housing, and lately I've been using the all-steel Earthwise 20" Li-Ion mower I picked up earlier this year. Steel is real !
