I am in the process of buying a tractor. The one I am looking at is a new non current 2011/2012 with 8 hours and it still come with the full warranty. It looks in good condition and is the same at the 2014 except it does not have the tier 4 engine and it is $23,000 vs $28,000 for the 2014. Is it worth the $5000 savings to have one with a tier 3 that has been sitting around the lot for that long?
