  • Waste of Money--Don't Buy!
Size: 21in/3-IN-1 170cc Self-Propelled
Bought this, set it up as instructed, added oil and gas. Mowed one section of the lawn, stopped the mower to walk it to a different section of lawn, and it would not start up again. It's not returnable, so this was a waste of $300+. There is fresh gas, fresh oil, and a brand new mower, and it konked out within about 30 minutes. ... show more

  • Fast speed only.
Size: 21in/3-IN-1 170cc Self-Propelled
Only 1 setting for speed and running engine. Auto drive is quick. Should be on front wheels to lift front of mower to stop and turn. Variable speed.

Size: 21in/3-IN-1 170cc Self-Propelled
The first one that deliver had the front left wheel bent into the frame. I had a replacement come and the back wheel was bent and broken. Packaging was not damaged. Now I have 2 mower neither of which are useable
