The Bob-Cat Predator Pro is as good a mower; as there is on the market. The Generac is the price lowering factor with the one advertised on Ebay. My dealer was the largest Bob-Cat dealer in the US last year, I saw the award hanging on the wall of his business. He said people were afraid of the Generac engines and he really could not say why because he had not sold enough to make a comparison. I have run the 33 Generac and the power is amazing, it ate a 28 hp Cat on a BB in a side by side comparison alive. The difference in the way both mowers handled the same grass was as if the Generac was 40 hp and the Cat was 20. That is an excellent price on that particular Bob-Cat, but I would say if it had the 31 Kawi which they offer; the price would be a good deal higher.
