Hiroshi Kim –
As someone who’s used a few of these before, not blown away by the engine power, but it’s serviceable. The starting reliability isn’t quite as solid as I expected for the price.

First impressions: The build quality does the job, though I wish it were a bit better. The bagging performance has been a bit of a letdown compared to what I hoped for. Compared to what we had before, the build quality is a big step up.
Karen Miller –
I did a lot of research before buying, and it took a bit of trial and error before the ease of assembly felt right. The self-propel drive gave me some trouble early on, though it’s manageable now.
Megan Stewart –
My brother-in-law and I picked this up last month and bagging performance is where this mower really stands out. I wasn’t expecting the ease of assembly to be this good for the price.
Jack Stewart –
A few weeks in, and the turning radius on this mower has genuinely impressed me. The fuel efficiency is decent, nothing to complain about but nothing amazing either.
Eric Evans –
Overall, it’s rare to find a mower where the build quality actually lives up to the listing. The build quality alone makes this mower worth it. Wasn’t sure about trying DEWALT for this category, but it’s won me over. Delivery took a little longer than expected but everything arrived intact.
Patrick White –
The cutting quality works better than I expected going in. One thing I really appreciate is the fuel efficiency. I was drawn to the 163cc rating when I ordered it, and it checks out.
Scott Peterson –
Bought this for my husband, and cutting quality has held up well after regular use. The self-propelled drive made the switch from our old one an easy decision.
Sharon Hall –
After a few weeks of use, even my dad noticed how good the noise level is. The bagging performance is acceptable, though a couple of the reviews online oversold it a little. Definitely a fair price for what you get.
Christine Hall –
Honestly, I’d say the cutting quality is about average for this price range. Had a minor issue with the noise level that I had to work around myself.
