My husband and I are in our 70's and still like to mow our yard. We have extremely thick grass bermuda and zoysia in our ditch. We had a $500 Toro with a Briggs and Stratton but it was so hard to change blade height, the drive was a workout and backing up a workout, plus heavy. We bought this lawn mower because of the reviews the easy blade adjustment, how light it was, easy drive and the reviews were correct. Easy assembly out of the box, light, easy blade adjustment, self propulsion, started up first pull and mowed perfectly through our thick grass. We also like to catch all the clippings not having a thatch buildup on our lawn. So far it is working awesome and happy for the purchase and the reviews.

I was led to believe this was an automatic start with no prime or pull. NOT TRUE! It needs priming, and the cord needs pulling. I couldn't get it to start. Felt like I was pulling my arm off. Which is one reason I wanted this so I didn't have to pull a cord. It's raining now so I won't be able to see if I can get to start until later in the week,but right now I'm not happy with it. If I can get it to start and it cuts my grass, I'll revise this rating and update my review. operation mode "Automatic start" is what was advertised; no priming necessary. Ok,I was able to use it. It mows great. But, they lied about no priming needed and automatic start. You do have to prime and you do have to pull a cord. Once it runs it runs great but it shut off once and I had to wait 20 mins before it would start again. To me, automatic start means using a button or switch, not pulling a cord. Also, the mud flap or whatever you call it broke half off in 20 mins and the part to hold the cord against the handle flew off to God only knows where within 5 min's of use. Also, the nut won't stay on the bolt. It's too loose. I took it to ACE Hardware to see if they had one that would fit and they didn't but suggested using superglue. They said the nut sent was stripped. So we'll see if superglue works. I have things to do and won't be using it again for 2 more days.At anyrate it mows great but not being as advertised kills the rating, that plus a lack of support. The support team never got back to me, and it's been 2 days so the 2-star rating stands. OK, at least I'm getting a refund. I was told to keep it or get rid of it. So today (Sunday June 15h ) I gave it one more try and now it fell apart completely. Now with both screws on the handles are stripped and won't stay on so it's useless. Changing my ratting to 1 star, but only because there's nothing there for 0 stars. I would stay away from this brand if I were you. You've been warned.

Just what the doctor ordered. Its exactly what I needed. Nothing less and nothing more. Sets up in a few minutes with no tools and comes with oil. I have a smallish lawn that's flat so I didn't need self propelled but I wanted a rear bagger. I'm happy.

The mower came missing the lever that controls the grass cutting height which should have been factory installed. We later found the lever loose in the box under packing material, it appears to be broken.. We have a brand new mower that doesn't work. Contacted both Amazon and the manufacturer, Amazon responded right away offering a 10% discount...ahem, Mower does not work. We are still waiting for the manufacturer to respond...it's been 2 weeks. No stars for a broken mower.

Had for 2 years, so far a pretty good mower. Must note that the specific mowing blades for this mower are extremely hard to find.

As I took it out of the box to assemble I noticed what appeared to be a handle of sorts. I picked it up and knew right away it was the blade height adjustment lever. It had been completely sheared off and broken. I am writing a negative review because (although it says differently) I am not allowed to return this item.
