John Reed –
Not blown away by the overall quality, but it’s serviceable. My biggest gripe is the build quality, which underperforms a little.
Sarah Jones –
My wife and I picked this up last spring and the value for the price is acceptable, though a couple of the reviews online oversold it a little. The ease of use isn’t quite as solid as I expected for the price. It’s rare to find a item where the ease of use actually lives up to the listing.
Robert Thomas –
My husband and I picked this up last summer and one thing I really appreciate is the ease of use. Ease of use has held up well after regular use. Delivery took a little longer than expected but everything arrived intact.
Katherine Ramos –
I did a lot of research before buying, and it took a bit of trial and error before the appearance felt right. Had a minor issue with the appearance that I had to work around myself.
Julia Allen –
After a few weeks of use, the packaging is decent, nothing to complain about but nothing amazing either. The packaging was the one part of this item that didn’t quite meet expectations.
Amy Long –
Been using this for about a month now and three weeks in, the ease of use is still holding up nicely. I’ve used other John Deere equipment before and this one fits right in.
Nathan Ramirez –
So far, what stood out most to me was the appearance. Ease of use took a little getting used to at first.
Femi Okafor –
As someone who’s used a few of these before, the appearance alone makes this item worth it. I was drawn to the 17.5 HP rating when I ordered it, and it checks out.
Rachel Reyes –
Overall, even my daughter noticed how good the build quality is. I’d say the build quality is about average for this price range.
Eric King –
A few weeks in, and I’ve owned a few of these before and the appearance here is genuinely better. So far the ease of use hasn’t given us any trouble at all. The hydrostatic drive made the switch from our old one an easy decision.
