Style: 140CC B&S EX550 Self Propelled
My son put this together for me in less than a half hour. He said it was easy to assemble. It runs great and usually starts with the first pull--I am 75 so maybe always on first pull for younger mowers. I live in Florida and the grass has been growing so fast this year that my electric mower could not handle it. This mower cut through the longest grass with no problems. WARNING: The self-propelled mower does not have a primer or choke like it says in the written directions. It does tell you this on the mower which my husband pointed out to me. I love it and highly recommend it.

Easy to set up! Comes with oil and manual. Good price-Briggs&Stratton power, bag AND SELF-Propelled. Second pull usually starts it and it’s a nice mower. It’s getting so mowers just don’t last very long anymore, too bad. I’ll see how this one works. Follow instructions, splash a tablespoon of 2-cycle oil in the spark plug hole, start it for a minute then turn it off. The rings need to seal.

We moved to a new house and went from a postage stamp lawn to 1/3 of an acre. And that 1/3 of an acre is basically rolling hills, so our previous battery powered mower wasn't going to be up for the task. I wanted something that could handle the lawn without breaking the bank. So I chose this mower. It does the job. I don't regret the purchase, but there are times that you can tell why the mower is priced where it is. For instace, the pull cord to start the mower comes unattached (it hooks to the handle) at least once every time I mow. (You have to depress the "power bar" on the handle to pull it out again.) If the bag is full it will sometimes fall off of the mower. (It needs to be emptied anyway.) Little things like that. Nothing that impacts its performance - and it does consistently devour 1/3 of an acre of grass. The power assist setting isn't something I use but my wife (the time she mowed the lawn when I was ill) mentioned that it helped her get up the hills. I've tried it once and for me it moves very quickly (brisk walk pace; I'm a leisurely mower, you know, sort of zoning out in a sem-meditative state as you walk behind it). With no power assist, I can mow the full 1/3 of an acre without refueling. My wife had to refuel while using the power assist. Long grass? Weeds in the back flower bed? The mower devours them all. I tend to think of 5 stars as excelleng and 4 stars as good. This is a good mower. Two thumbs up, but it does have its quirks. We'll see how well it holds up over time and I'll add to this review if necessary.

The mower was delivered well packaged as advertised. Simple to complete the setup and was running smoothly, only needed to add gas and some of the supplied oil. I think it was a very good investment. The packaging was unharmed in shipment. Thanks for providing a very good product at a reasonable price.

Great value, good craftsmanship, self propel feature has strong torque, easily adjustable height one lever does all four wheels, strong durable bag. Totally satisfied with my purchase first time I used it to mow my quarter acre lawn was able to do it in half the time.

Mower arrived on time. Easy to unpack age and assemble the handle. Filled mower with oil (provided) and gas. Mower started on first pull! While the 140cc power is ok for cutting grass and to drive the self propulsion. However, after one use, this mower will not last a long time due to too many plastic parts. Ok for small yards and once a month use. Pay more to get a better built mower…

The lawnmower works perfectly fine, good for a small yard. It came broke from the plastic base that hold the front wheel but they refunded the money. It has oils all over, nothing impossible to fix, besides that, the engine is strong and it does what’s supposed to do.
