Went and looked at this machine this morning. It's 2 years old, electric start, mulching deck only, but in perfect shape other then one caster wheel on the front has a chunk missing but still rotates just fine. I did a search and came up with pretty good opinions of this mower even though it's not commercial grade. My use for this mower would be to replace the 21" I have to use on a couple backyard situations due to gates. And a couple steeper slopes that I could do straight up & down, going sideways may be tough due to the drive system on this mower. Is it worth the $500? Looks like they sell for around $1400-1600 new. I run it around his yard and it puts down some nice stripes.
