Kubota Diesel engine on this 72" with mulching kit is under powered. The mulching is awful, it mulches great on grass that doesn't need mowing.
I have a 13 year old Exmark 31 hp 3 cylinder gas 72" and it mows circles around the new one. Tried all kinds of blades, blade pitch, nothing even gets it close to the old one. I can use worn out blades and still does a better job than the new Exmark. Very disappointing. Deck design on the new mower is not the same as the 13 year old deck. Why change a great deck design.
