I've gotta side with Morkai. I've never been impressed with the cut of my 2544. It's not BAD, but it's not great, either. My neighbor's Ferris 1500Z cuts far better and at twice the speed. I mowed with it over the summer while they were on vacation and went through grass 7 to 8 inches high at least taking it down to maybe 4" and the speed at which the deck could process that much very thick, very green grass was amazing.
On the contrary, my 2544 would have went through it OK, but left a lot more clumping and left a lot of it uncut and merely bent over. I do think the Ferris has even higher tip speed than the 2544, though. Between the Kawi engine wound up and the deck, you start to look for where the B-29 is...
My theory (after pulling the Ferris apart to sharpen his blades) is the 2544 deck has the blades mounted up too high inside the deck. If the grass is tall, it is still bent over by the front of the deck by the time the blade gets to it. The Ferris has the blade even with the bottom of the front lip and there are actually adjustable baffles at the front of the deck to control the grass intake.
I would bet that spacing the 2544 blades down 1/4" or so would make a big difference in cut quality. Otherwise, I see no reason it can't cut well - it's a deep, well baffled deck.
