I am purchasing a small Z in the next month and I'm trying to figure out what is the best deal. For my dealers open house they are selling the new Exmark for 4599 and the Gravely for 4099. By the time that I put a 17-19 Kawi on the Gravely and sell the 15 they will be pretty much identical $ wise. I'm wondering which mower will mulch better? Do you think the new hydro set up on the Exmark will be as good as the Gravely?
