Anyone have any opinions on JD 5420? We've always had old worn out tractors that you usually have to spend more time working on than you do using them. We are thinking of upgrading and there is a 5420 for sale here. Anyone have suggestions about this tractor or others in the 65 hp class? I'm looking for a reliable tractor to feed with, bushhog and plant winter grazing. Probably won't pull anything heavier than a 10 ft pull type disc or 7 foot tye drill.
