Let me explain.
in March, 2017 I purchased a Greenworks 21” 60 volt cordless lawn mower that mentioned in the manual an optional heavy duty blade that promised improved bagging and mulching performance at the expense of higher power drain on the battery. So, I searched the internet and queried Greenworks in a vain attempt to purchase one. Nothing at all could be found for a year, but then in March, 2018 I purchased a switch for my Greenworks Twin Force from a new greenworks.ordertree website, and decided to try again. This time the part number for the heavy duty blade showed up and the website accepted my order. But then there was silence, so after a week I emailed customer service to inquire on the order status, and was told the the item was backordered and there was no information as to when or even if the item would ever be available. Since I had not been billed, I just left the order in place and forgot about it. Anyways, a few days ago about four months after placing the order I noticed a charge on my credit card from ordertree, and when I checked my greenworks.ordertree account later that day I saw that the status had changed to “shipped”, and there was a UPS tracking number. The blade showed up yesterday, and I tried it out today, although with my lawn dried up from the summer heat and drought, I have no way to tell how much of a difference it makes. The only apparent difference between the stock blade and heavy duty blade is the shape of the tips. Whereas the stock blade has a substancial taper at the ends, the heavy duty blade has almost none, which I assume creates more lift to improve mulching and bagging, but also consumes more power that reduces runtime.
The difference between the two blades can be seen in the attached photo:
