I'll have to say that the bidding looks very suspicious and I suspect the seller is running it up with another ID. There is so much of this going on now on eBay it's just not funny.
eBay made it slightly less transparent a few years ago but I think it's time to revert back and expose this practice, but then again why would eBay want to as the get a higher Final Value Fee.
BTW I think the front has had it's lower lip broken off as you can't see it across the whole width of the mower and the seller has specifically taken the shots so as not to expose that section. There is a Yellow one up at the moment and it has it's frontal lip.
Cheers,
