I am in the market for a 72" ZTR diesel. I am looking at the Exmark XP and the Kubota ZD28 72" pro deck. I understand that Hustler is going to have a 34 HP diesel soon. What are the people's opinion's/experiences with various diesel ZTR's for commercial usage - e.g. Exmark XP 27 diesel (72") vs Kubota ZD28 (72"), vs Gravely 72" 31 HP, etc. Also Exmark has that 31 HP gas - the Exmark XS in 72" but nobody in my area seems to have them just yet (may be mid December). I've looked at all the specs. Demoed the Exmark XP 27 HP and the Kubota ZD28 72". The both look fine. I like the exmark due to the fact that there are numerous aftermarket parts/blades, etc. Who cuts better. Does the 27 HP Daihatsu diesel bog down. Any feedback would be greately appreciated. --ed in Northern Virginia.
