  • Good Little Mower/Easy Set-up
Is this comparable to a $400 mower? No. It is, however, budget friendly and gets the job done. My 14 year old mower finally aged out and I needed a replacement. Keep in mind I mow 5 acres. My Gravely ProTurn 460 handles 99.9% of this. What I do need is a small push mower to “cut in” around the pool, fence, shop, walks, and up close to the house/landscaping. This thing fits the bill! The power is good, it’s light, and decently sturdy. It would be a great mower for a smaller 1/4-1/2 acre yard. When assembling the handle, 180° the instructions for the left side drop-down orange wing nut. The way you can get up against a fence, especially chain link a not drag/hook. A couple of dings: I wish it had a “mulch flap” instead. You have to plan your direction in tight quarters. The wheels are overly cheap. Not sure about their longevity. And if you hear a dinging sound, it’s not Hector from Breaking Bad behind you. The pull cord recoil is tight and makes a ringing sound if the handle flexes too far. Overall, I’m impressed. Nice little mower for the money! ... show more

  • Great for the price
Lawn mower has worked great so far! It is smaller but also affordable. I didn’t have $400 to spend so this is perfect for the price. It’s light weight, starts easily and cuts the grass.

  • The Best Bang-For-Your-Buck Mower
This was my first lawn mover purchase (new home), and I'd recommend this particular mower to anyone who needs something that does the job, does it well, and doesn't break the bank. It arrived within a week of placing the order, took maybe 25mins to put together (get it out of box, gas, oil, etc), and started on the first pull. Probably my best amazon purchase to date - and I've been buying things on here since 2016. Note: We don't have a really big yard space (front + back), and while this would work for any yard, I think its best used in suburban neighborhoods w/ modest to decent size yards. ... show more

  • Nice
Works as expected, starts on the first pull, motor works great however the wheels adjustment popped out of place when mowing have to put back a bit of a pain, but for the price I can get over it

  • Very impressed with this little mower!
This mower is GREAT! Out of the box, there was basically no assembly, just snapping the handle into place and tightening it down by hand. NO TOOLS REQUIRED! Starting dose of oil provided, a little bit of gas, cranked on 1st pull, and it was very quiet for a mower. Very lightweight too! Easy to adjust the height, again, no tools needed. I have RA, and have stiffness and weakness, but even I was able to start the mower, and was so happy! We bought it for some areas we can't get to with our riding mower, and rarely make it to with the weedeater, so they were pretty grown up with weeds and baby trees. This mower ate right through it with no trouble. It is a great little quality mower, and definately a great value for the price! ... show more

  • Very Poor product, manual information
I found the information for this product was very poorly presented after purchasing the product and reading the product manual. After I receive the lawn more and trying to fill the gas tank with gas, there was no information on exactly how much gas it would take to fill it up properly. Furthermore, there was no information as to exactly how much oil it would take to fill the oil tank properly. When I used the information from the product manual to find this out, I was asked to give a credit card number in order to answer the question which also said it would be immediately refunded? I don’t think so. This was very annoying and concerning. Why do you need my credit card number to answer a question about your product when I’ve already paid for it with a credit card? Furthermore, The access to the oil orifice was very difficult to negotiate. I thought Briggs and statin was a good product. The information was very difficult to find Without offering my credit card Number to get the information! Boo! The information provided about the grass catcher when considering the purchase of this product was not included, and the information on the product manual does not state if a grass catcher accessory is available to purchase with a side discharge. Being a first time buyer, I did not realize this may be a problem. It would’ve been really nice if this information was stated in the reviews for this product. ... show more

  • YES Its a Great MOWER!!!
This is a great little mower! It arrived in 3 days in perfect condition. I am an old lady with arthritic weak hands, and I was able to put this together in about 15 mins with NO TOOLS!! Oil was included so thats a plus! My grass was a foot tall in many places and this chewed right through it! This is lightweight and very easy to push. It started on the first pull! Directions and manual are on point. The only con for me (because of low mobility in my hands) was to raise the wheels, but for anyone else this is easy! Very happy with this. It took me 3 days to mow an acre of tall grass with this mower but I'm here to tell you...this mower understood its assignment!!! ... show more

  • Great Little Mower
I was pleasantly surprised with this little mower. I have used it about five times. It is small and lightweight. Some may not think this is a good thing, but it’s very easy to crank and mow. My yard is hilly and uneven in the back. This mower handled it easily. I hope it will last!
