Style: 20 Inch 125cc Gas Mower
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!

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!

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. Can you believe the wheels fell off after the third time of using it-unbelievable! I had to tape them on to finish mowing the lawn.

The mower arrived well-packaged and fully assembled. Setup was straightforward and easy. Although it’s a bit heavy, it operates smoothly on both flat ground and slopes. After using it for a month, everything is working as expected, and the noise level is acceptable. It did stall once when I tried to push through a particularly tall and dense patch of weeds, but overall, it handles tall grass quite well and performs reliably.

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!!!
