Considering a tractor upgrade

Rod I used to sell JD for 20 years. Have been retired for two years. I have had 5 JD 455 lawn tractors and did not have any problems with any. It would be a good up grade for a 420. The diesel is very efficient on fuel- but you might not put many hours on it. Snow blower will need a different pto shaft to make it work. Good luck with the upgrade you will enjoy it. Jay
