  • Good mower
Color: Yellow
I have only used this one but it work very well. The self propel goes kinda fast but you get used to it. My husband put it together in like 20 mins and my son and I were able to fill the oil and gas with no problem. So far so good.

  • Broke first time
Color: Yellow
Out of the box you need to attach cables to the handles which are too short if you follow directions to attach handles first as instructed. There were zero instruction on how to attach the cables so you need to figure it out yourself by attaching them to upper handle before attaching upper handle to lower handle. First cut the belt that operates the self propelled part came off track, you can’t get to it either without removing a plastic cover that’s attached to frame by a cotter pin hammered into frame no screw tip. It’s now a push mower which actually cuts very well but the reason I got it was self propelled and it broke first run ... show more

  • Damaged package
Package was damaged after delivery from FedEx, but product seems to be fine and is in good working order so far. This is the second item that I’ve had. The package was damaged delivered from FedEx. I don’t have that problem with Amazon delivery but so far so good I’ll keep you posted.

  • Self-propel only has one speed.
Color: Yellow
I've only used this lawnmower once. So far it will only start after 3 or 4 pulls. The self-propel only has one speed, and it is pretty slow. I'm old so that is ok with me. I would like for it to go a little faster. I would want to go slower in tall grass. It feels heavy to me. It is kind of hard to push or pull. Again, I'm old and week. It is easier for me to go the extra step and turn the mower around and use the propel rather than pull it backwards. My back hurts after mowing once, but there are other reasons why my back might hurt. It will do for this summer, but I think next year I will do more research and get a better mower. It does look good, and it cuts well. ... show more

  • Great mower!
Other than the blades being a little dull, this mower works very well! It still glides thru longer grass with ease. I was skeptical about ordering a lawn mower online but we are happy with this one!

  • Dont buy the mower!!!@
Color: Yellow
This lawn mower is not even worth how reasonably priced it was. One problem after another. Returning it is a hassel after its been assembled and used. Quit working before I even finished cutting my front lawn. I dont usually write reviews but dont want others to make the same mistake I did ordering a lawn mower on Amazon. I should have bought a Toro. ... show more
