Faisal Ahmed –
After a few weeks of use, it took a bit of trial and error before the ride comfort felt right. Had a minor issue with the seat comfort that I had to work around myself.
Jerry Bailey –
As someone who’s used a few of these before, one thing I really appreciate is the ride comfort. The ride comfort is acceptable, though a couple of the reviews online oversold it a little. Good value for the price, all things considered. I was drawn to the 22 HP rating when I ordered it, and it checks out.
Joshua Wilson –
Honestly, the engine power works better than I expected going in. I wasn’t expecting the deck size to be this good for the price.
Heather Washington –
A few weeks in, and the ease of operation alone makes this mower worth it. I’ve used other John Deere equipment before and this one fits right in. The zero-turn steering is exactly what sold me on this mower in the first place. The box showed up a couple days earlier than the estimate.
Raj Fernandez –
Bought this for my wife, and engine power has held up well after regular use. Even my daughter noticed how good the ease of operation is. Shipping was quick and it arrived well packaged.
Timothy Brown –
Overall, I’ve owned a few of these before and the cutting speed here is genuinely better. I’d say the ride comfort is about average for this price range.
Betty Roberts –
So far, it’s rare to find a mower where the deck size actually lives up to the listing. The seat comfort is fine — just don’t expect anything extraordinary.
Jack Hughes –
My brother and I picked this up last spring and so far the time savings on mowing hasn’t given us any trouble at all. Not blown away by the stability on hills, but it’s serviceable. A little pricey, but I think it’s worth it.
Stephanie Collins –
I did a lot of research before buying, and the stability on hills does the job, though I wish it were a bit better. If I’m being honest, the turning radius could use some improvement.
Jonathan Moore –
We’ve had this since summer and three weeks in, the overall build quality is still holding up nicely. Compared to what we had before, the seat comfort is a big step up.
