Worth the investment

Great lawnmower, highly recommend. I hate to admit it but my grass was about 5-6 inches tall. In my area the cost is about $100-$150 to get my grass cut so I just saved and made the investment to cut my own grass. This lawnmower got the job done. I did have to cut it off to give it a break because my I did my front yard first then the back which is huge but you can see how tall my grass was near the garage. Must buy!

Good mower for the Price

I'm use to a riding lawnmower but moved from 5 acres to .33 acre. Cranks first pull, one speed . Light weight. Overall not a bad mower for the price.
