Well I finally got my chance to test out the new Gravely prototypes, a 36" belt and and a 48" hydro. The 36" came with a Kawasaki 13 hp [bold]twin[/bold] that is very smooth. In a head to head comparision the Gravely 36 cut grass as well as my 36" Exmark Metro in almost every catagory. The mower is very fast, 7.4 mph. The new 48" hydro floating deck is a very nice machine. It came equipted with a Kawasaki 17 hp twin electric start. The mower deck on this machine is awesome. It came with double blades from the factory and it cut right through everything I had to cut. One of the neat things on this mower is the angled front casters. On most mowers the casters stick straight out of the front of the deck making it difficult to get in close in inside corners. The casters on the new 48 are angled in toward the center of the machine making inside corner cuts much closer that any other machine I have ever used.
