I am taking delivery of my new Kubota ZD28 w/60"Prodeck today. I traded in my 10 year old T1600 Kubota, which was an excellent machine, however, it had a bagger and I tired of constantly emptying the bags. Plus it was somewhat underpowerd for my hills. I mow about 6 acreas and feel that this will last me a lifetime. I appreciate all of the input from this site, which played a big part in my decision to buy the ZD28 rather than the ZD21.
