I am wondering if anyone else sees a resmblence between the 2 decks ? My Super Z has the same type of cutting issues as the Gravely 260 xdz x factor deck I am demoing. I also noticed both decks are tapered deep in the back to shallow in the front. Super Z 6"back 4 3/4 front without the addons for blowout. X factor deck is 5.5 inches back and 4 3/4 front. Both have the blades lower than the baffles toward the front of the deck. I'm not impressed with either deck for our northern grasses. To bad I'm running out of mower options up here. I need good mulching mowers. These are of the gravely x factor deck.
