    DeWalt’s product page for this mower (link removed) says, “folding handles for compact upright storage”. What’s that mean exactly? Have a picture of that “upright storage”?

      Hi Dave, The main handle of the unit will fold down over top of the battery compartment and you will be able to store the mower on end instead of on all 4 wheels giving is a smaller footprint. We do not have a mower on hand to include a picture of this but we should have one later this month where we could show this on social media.

      Thank you,

    The video on the product page mentions “Belt Driven”. Is it really belt driven? Is that going to be a serviceable part?

      Hello, Thank you for your question. We have had very limited time with this mower but we can see that there is a belt on the parts breakdown. The belt will be serviceable and its part number is N538640.

      Thank you,
