I have the exact mower with self propelled. With that battery, I can mow 10,000sqft of maintained lawn per charge. It will increase the rpms when the motor slows down in thick stuff. My lawn is level so I have no need for the self propelled function but it is adjustable and full speed is a brisk pace and slows down to a crawl. It’s a separate handle obviously so easy to engage or disengage. If you don’t want it, save the $100. The deck is metal FYI but I think metal has pros to a plastic deck that justify it. I love the 80v blower and I have seen the backpack style one in person and it seems great if you can justify the purchase. I also have the trimmer and it’s good, I just wish it was a little faster so it could easily handle a power rotary scissor attachment I have. Also have the 16” chainsaw and it’s been great for the little bit I need it.
Links to what I have. They offer different blowers and trimmers, these are the better ones.
