    • Good machine
Style: 140cc B&S Push
Very Nice and versatile unit. The front and rear cutting height adjustments work very well. Once oiled and fueled, the B&S engine started on second pull after priming.

    • A great mower...when it works - Terrible Customer Service
Style: 140cc B&S Self Propelled
Did not come with all of the bolts needed to fully secure the belt cover which resulted in the belt cover being damaged and causing the self propel to break. Taught myself to take everything apart and attempt a repair of the belt cover myself. Works well for a few more weeks then breaks again. I decide to say screw it and buy a new belt cover for a 3 month old mower, just to find out GOOD LUCK getting a replacement as theyve been sold out for ages, no one else carries them and their customer service is BEYOND pathetic. They'll play 20 questions with you just to be absolutely useless and waste more of your time. All of this is sad to say because when the mower is working right, it works well imo. Too bad looking at other reviews, the machine falling apart and TERRIBLE customer service is more common than the machine working properly. Avoid this terrible company who doesn't care about you or quality assurance, just taking your money. ... show more

    • Good 4-stroke mower.
Style: 140cc B&S Push
Very nice mower that was mostly assembled and the rest of the assembly and set up was easily accomplished by my daughter. I liked that it came with a quart of the correct oil. I guess I didn't read the description on Amazon but I was surprised to find that it was a 4-stroke engine. That was a real bonus for me. ... show more

We own a landscape company and needed a push mower for some of the smaller yards. This lawnmower has been perfect. It was affordable, it looks nice and it gets the job done.
