I didn't know Billy Goat made homeowner quality equipment, looks to be a commercial mower to me. Looks like those Bradly mowers must be purchased through distributor only? I've never seen anyone use a Bradly.
I've seen those Billy Goats on eBay for about $1500. I looked at these at a recent show, and I thought they looked pretty decent for the right use. In other words, I wouldn't use one as a main mower, but for very small properties and small gated backyards it looks like it would be a decent choice.
Of course, that's assuming it cuts good!.
I have a few lawns where I can't even get my 36" mower through the gate, so a 33" would fit nicely.
One thing I liked about these was the very small footprint. They are really compact, much shorter then a traditional WB. Which would be good in a compact yard, plus it would take up less trailer space.
If I was in the market for a mower under 36", the Billy Goat would be on my list of options to demo.
I purchased a Contour last year for certain properties and its taken the place of the other push mower I had. The contour is heavy in certain situations but have never had a problem with it mechanically.
Both these designs look interesting for occasional use. They're not beefy full size mowers, but then they're not supposed to be. I like the idea of being able to squeeze one on the back where a bigger mower wouldn't fit. And not having to invest $2500 in a rarely used mower is nice too. But as always, the devil is in the details, so they'd have to be available for testing for me to be interested.
