    • Great value
Set name: 22"-201CC
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

Package was pretty much worn out tore up and tape was unsealed not a reflection of product just the way it’s handled through shipment. Needless to say I was worried about what lay inside and what could possibly be missing. Thankfully in my situation nothing was missing or damaged. Assembled and put together in under 30 minutes. Cranked right up! The self-propelled feature is a life saver especially for bigger yards. The height adjustment kind of sticky but does lock in place nicely. So far works as advertised. ... show more

    • Senix 22" self propelled 201cc lawnmower
Set name: 22"-201CC
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.

The lawnmower felt very flimsy right out of the box but it did the trick. I used for a couple of months and everything was fine until it wasn't. A metal part that runs under the frame between the two rear wheels came off and got caught in the blade, bending it and seizing the engine. I have tried to contact Senix for the warranty and have been unsuccessful. ... show more

    • Nice machine, I like it
Set name: 22"-201CC
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

    • Tbh it’s a monster of a mower. Just eats.
Set name: 22"-201CC
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
