I am in the process of deciding which tractor I am going to buy. I am pretty much sold on going with the John Deere, but am open to suggestions. John Deere and Case are the big dealers in my area. The tractor will be used in the business from time to time, but we are mainly a mowing/maintenance group. Landscape is not big for my business. So the main item from a business standpoint would be loading mulch from the pile into the trucks. I also own 7 acres of ground, and will be using it around the ground for various things. I have looked at the 3320, 4520, and the 990. That 990 unit sounds pretty inticing to me. Anyone have thoughts on this?
