This 21 inch mower took less than 15 minutes to put together and start mowing. Comes complete except for the gas so its ready to go. It offers adustable cutting heights. Its self propelled so easy to use. It functions like a mower should and cuts very well. The compact size and foldable design is nice when it comes to storing. The engine is a 4 cycle 170 cc so it has the power we needed. When it comes to the engine is appears to be durable and has the power it should. It starts right up and has all the normal safety features. The grass clipping bag is easy to put on and take off. It holds a average amount of clippings. The tires are able to handle going down in to our ditch and back up with out hesitation. It did well cutting some of our thicker grass. Overall we are very happy with our purchase. ... show more

    • Most excellent self-propelled Pushmore!
Size: 21-inch
The mower came very well packed in its box. It was easy to put together and it ran great on the first start up. I have had other separate propelled push mowers, but this one really pulls itself! Right now if I had to buy another Pushmore, I would buy this one. The rear wheel drive really does a good job going up and down small heels. Also, you need to be in good shape to stay up with it cause it will pull you alone with it. I made an excellent choice! ... show more

    • So far so good.
Easy set up and started right up. Seems like strong engine and the rest is just mid to low grade but works well. I will only use is for very small lawn over septic and clearing for fire once a year. 4 star is for strong engine but cheaper components surrounding it. They do not send you enough oil to fill it so have some on hand. ... show more

    • Not what I expected
Size: 21-inch
Not what I expected. Had to pull so many times to get it started. No way to adjust how fast it’s going to pull you after you do get it started, I was practically running. I tried to contact the seller, on the starting problem but didn’t hear back from them. I would not recommend this product!
