    • Hold onto the lawnmower, cause it will take off on you
Set name: 21” 170cc Self Propelled OHV Lawn Mower
This lawnmower has a lot of power. When you press the self propel handle, it definitely takes off. You have to hold onto it. I purchased the first one and came damaged. The wheel was not operable. I tried to return it, but I could not so they sent me another one, and I have been completely satisfied with it from this point on. Note to the seller be careful how it’s packed because the wheels were broken and shipping and when it came out the box, there was pieces of it. I did send a photo to the seller. So just be careful anyone else that purchased this inspected closely. It is easy to maneuver. It is very lightweight. Easy to use and start. Adjustment is far easier than any other lawnmower I have purchased. It is very fast. ... show more

So heres an honest review. It came with everything. TOTAL plug and play. Took 10 minutes, ready to roll. Plastic stuff yes but nothing that threatens performance, very solid, safe steel deck. NICE looking machine too. So tonight I wanted to see what the hype was. First off if you get ANY machine with one speed. Engage. Dont half engage, thats gonna wear stuff out. So that time came, Im like is this motor gonna start. I heard these ones are powerful. Yes it did.. After oil I let it sit for a bit. Two pulls it fired up like something Ive never seen in a push self propelled mower. Boom...now thats a motor. So I let it run. I ENGAGE and wasnt ready for it. That thing said dude get ready. It nearly pulled me off my porch. Made my day. It wants to Go.......Id recommend. ... show more

    • Satisfied Overall
Set name: 22” 150cc Self Propelled Lawn Mower
Overall, this PowerSmart 22” self-propelled gas mower works well. It’s a Briggs & Stratton motor, so I wasn’t concerned about motor performance. It arrived completely assembled, all you need to do is unfold the handle and tighten the hand screws. Easy! Setting the height is extremely easy. (1) handle adjust ALL (4) wheels. Very convenient and quick. The deck is solid metal and the only plastic is at the rear, bagging area. I used it to mow an abundant amount of leaves I couldn’t get to last year. I was very satisfied with the mulching. I would attribute it to the 150cc motor, the self-propelled speed and the enclosed deck. There is no speed adjustment for the self propelled feature. It makes mowing easy but runs very slow. This 150cc will consume furl faster and will likely burn oil faster, but the power is worth it to me. (2) pulls, after unpacking and prepping, hot it started. (1) pull the next two mows. No priming, love it. I did not see a place to hook up a hose for cleaning the deck interior, so it will be interesting to see if it builds up debri and how easy it will be to clean. The overall feel of the handle (gripping) is ok and feels a bit awkward while mowing. Something to get used to. No major issues or concerns at this time. Only (3) mows in though. If anything changes I will definitely update the post. ... show more

    • Bad product from a very bad seller - BUYER BEWARE !!
This PowerSmart mower looked like good value so I bought it and it shipped direct from the seller. Within a week the rubber skirt at the rear of the mower that protects operator from flying stones or debris came off. Amerisun Inc., shipped a replacement that took a month and they're in IL, and I'm in TX. Literally a week within the 12 months warranty the pull start mechanism broke. They did not respond promptly via Amazon customer support from the seller. I tried to call their customer service direct and put on hold for over an hour when I finally got a chance to leave a message. They did not return the call then and for 3 more times I left a message. They never answer their phone. They never responded to direct email as given on their website. Finally I had to complain via Amazon and after more than 1 month Amerisun, Inc., responded and over the following weeks of back and forth attempts to get the machine serviced with new parts they finally offered a replacement or a refund. I opted for a refund as the grass doesn't stop growing in summer and this company does not have a service center in TX or nearby state and, they essentially have no customer support when their machines malfunction. I had lost faith in PowerSmart and the distributor. However, they will only give a refund if I ship the mower back to them in Chicago Illinois at my expense, estimated by UPS Store at $150. The problem is that it is now a used mower and even if I drain the gasoline out there still remains fumes and neither UPS, FedEx or common carriers will handle it now being "hazardous". The importer of this China made piece of **** , Amerisun Inc., clearly cannot service or repair their faulty machines and will not accept responsibility by not responding to requests for help. I have finally spoken to Amazon customer service who have contacted Amerisun on my behalf. Hopefully Amerisun Inc., will do the right thing and refund in full. Then there is the 3 year protection plan that I purchased with the mower at $48.99 from Asurion who would not help in this matter as that the mower was still under the manufacturer's warranty when the problem came about. I pray that will also be refunded. BUYER BEWARE !! ... show more

Does better than I expected. I didn’t know what to expect from this push mower. I have a ride mower but part of my yard is slanted so I bought this. Works like a charm. It’s easy to start, has great cutting, definitely worth the money.

    • great mower
Set name: 22” 150cc Self Propelled Lawn Mower
I haven't shopped for a mower in 15 years, but it was time as my last mower was tired. I went looking at my local big box store and was shocked to find that they didn't carry a single gas-powered mower (CA). My yard can get pretty rough, thick weeds and gopher mounds, so I need a tough mower. The battery powered models are all plastic it seems. So I went with this one, partly because of the good reviews, (only 4 reviews when I bought it) and also because it was the only one with an all-steel deck. So I hurried and ordered it, before it was too late. It arrived and like others said, nothing to assemble, just took it out of the box, unfolded/tightened the handle, added oil and gas and it fired on the first pull. It cut the lawn with ease; the self propelled feature is nice, I've never had that before although I look at extra features as more things that can break. Hopefully parts are readily available and will be for a long time, but who knows? But for now, based on first impressions, I am very pleased with this purchase. ... show more
