    • Good Little Mower/Easy Set-up
Size: 20 inch 125 cc
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

    • Nice machine, I like it
Size: 22 inch 201 cc
Mower came well packaged with hard reinforcements in the box corners. Delivered on time with package in good condion. Mower comes with a small 15 ounce bottle of engine oil, perfect amount to fill the oil reservoir. Assembly was a piece of cake. Put gas in it and it started on second pull. Ran wonderfully and mowed nice and smoothly. Rear wheel drive on the big wheels works very well on the uneven terrain in our yard. I like it. ... show more

    • 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, and manual information
Size: 20 inch 125 cc
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. ... show more

    • Great upgrade from Toro.
Size: 22 inch 201 cc
Cuts thru grass like a hot knife through butter. Much better than my 150cc Toro.Easy assembly and mower level is with one handle.

    • Tbh it’s a monster of a mower. Just eats.
Size: 22 inch 201 cc
Nothing is perfect. But I’ll tell you,I’m a no bull kinda of guy. I’m too cheap to buy a Riding mower. I’ll push cut a few acres. But this thing. I had the previous I think 159cc,but this 201 is a monster. I honestly tried to break it rough out of the box. Oil assembly,bam 2ft grass straight abuse. It did great. Bagged some sand burrs. Shredded the rest. Solid mower. 2nd senix mower. Will definitely buy a bigger displacement if offered. 👍👍👍 ... show more

    • Great value
Size: 22 inch 201 cc
The engine started on the very first pull. It is heavy bu also heavy duty. This lawnmower is worth the price for what you get. I have a rough terrain and tough lawn and so I bought this because of the engine size. It handles my lawn with ease. Highly recommend

    • Senix 22" self propelled 201cc lawnmower
Size: 22 inch 201 cc
Basically 99% assembled, no tools required. Added the oil provided, added gas and it started right up. Has more drive power than I anticipated, I almost wish I'd just got the 170cc instead of the 201cc. Clean cut. Happy with my first mowing experience with this product.
