Customer Reviews

21 in. 140 cc OHV Briggs and Stratton Walk Behind Gas Push Mower is rated 3.7 out of 5 by 925.

I waited a year to write this review because other reviewers had difficulty starting it after winter layover. However, I drained the gas tank per the instructions before storage, put in new gas in the Spring and it started right up! This is a poor man's Toro and likely adequate for most lawns. It starts up after one or two pulls and doesn't require priming or choking. The grass bag is on the smallish side requiring frequent emptying and the two retaining screws that hold the handle to the mower hamper bag removal and attachment. Also, whether by design or design flaw lawn clippings shoot out of a gap between the bag and the holding door. Other than those minor gripes, I think this is a good mower for the price.

I used the other in my lawn care business and wore it out. Probably had 500 hours on it. Starts quickly and runs strong. Light weight and easy to maneuver. Bag capacity is a little small but if it was much bigger I guess the extra weight when full would probably be a drawback. I would buy another one.

I am 32 years young and this is the first time I have ever needed a mower or mowed grass. The yard machine was very easy to assemble, instructions were clear, and it even came with the oil to put into the engine. The mower started on the first attempt and I immediately felt accomplished. The wheels were very easy to adjust to the height that I needed. Needless to say this is a great product and very easy to use. I would definitely recommend this product.

Fortunately, right after pulling it off the shelf, another customer stopped us to rave about the yard machine mower. We were appreciative for the unsolicited feedback because we didn’t know what to expect even after reading positive reviews. Nonetheless, my husband loves the mulching capability.

We bought this mower because the picture showed an uneven terrain with obstacles. We're making trails on 37 acres of wooded, hilly property and this was a "cheaper" alternative to a box blade. This mower has been upill, downhill, gone over stumps, rocks and everything in its path and it's still going strong. We have made lots of trails and only had to clean out the air filter. Even if I had to buy another one to complete the miles of trails we're making, it'll definitely be worth it. It takes a beating and definitely lives up to its potential of being able to go over uneven terrain with obstacles. Great product!!!
