I purchased a house in November with 5 acres of land with a good sum of trees and found out my 25 HP John Deere tractor with a 54" cutting deck was going to take far too long to mow. I recently graduated to a new Kubota ZD331 with a 72" deck. There is no comparison between the two and I cut my mowing time to about 1/3 of the time it would normally take me. The Kubota diesel machine is truly an awesome way to go and built with top notch quality and engineering all the way.
