I have one of these old girls too! Kinda like that old shoe you cant to give up on. And pretty much a Deere guy. These are fun old tractors. Turned mine to about 300 hp. She really rolls coal when you pull her hard. Big 20.8 tires on it too. I worked on potato farm where we had 7 4366's and 3 4386's 7 of them were on live bottom wagons. These were fixed really nice. New roof air units, cab kits, door seals, floor mats, AM/FM radios and new seats. 2 were on dirt wagons in the yard and 2 spares. Fun old tractors. I bought the best one $2750 when he moved up to 91 and 9250's on the wagons
