Great quality for the money!

My last mower was from Amazon and didn't last 3 seasons so I wanted to spend a little more and get one with an extended warranty with high reviews. Not knowing the brand I was skeptical but to my surprise the quality of this mower is heavy duty. All of the parts are high quality, even the plastic knobs. I have mowed 3 times and this mower is a beast. The self propelled function is strong and saves my back. The bagger is high quality, large capacity and easy to empty. The large rear wheels make navigation easy. I'm sure this mower will last a long time for me. I would highly recommend!

Good bang for the buck. Was EZ to follow for set-up from the box. Would recommend not using the entire bottle of included oil for it may be a tad to much. Seems to have plenty of power even with a slightly high grass cut. Yard looks great with my first cut.

The self propelled part of the mower isnt very good.. but the motor and blade works very well.. the self propelled part is not so good.. yet i didnt plan on getting a self propelled mower anyways and didnt realize i had purchased a mower that had that feature.. It mows very well though and is relatively sturdy.. and i would like to note a friendly reminder to not forget to put your oil in before starting your job/tasks.. the blade delivers a very sharp and clean looking lawn.
