Wish I knew the answer to that question, but when I bought my 21" SP mower back in April it was marked down $50, then got HD's military discount. Saved me $100. Love my EGO mower. Have since added the back pack blower and just received the Power Head Unit Kit (edger and trimmer). EGO yard tools are the real deal. USAF Retired
I got/get some what I call "Mohawking" in my lawn, but overlapping my cuts a few inches more and slowing my speed has all but eliminated it. As far as the speed, I have COPD so w/o the gas fumes from my old mower I can get out there get some exercise, so slow works for me. So it takes me about 30 minutes longer to cut my lawn than before.
Thanks. I'm probably going to get one it's a question of when. I ran my gas mower out of oil and the engine stopped. I quickly filled it then started and it's run fine since but.... My only concern with the EGO was the 'mohawking' comments I've read and people saying the blade needs sharpened like every other cut.
