Well, I called my dealer back and he said it was rimguard. That is kinda a let down that maybe my tractor isn't as sweet as I thought. He said he just likes to call it molasses because that is what it is like to him. I asked him how much to fill my 13.6x28 tires on the AC WD - $3.25 per gallon and he said I could put in as much or as little as I wanted - is there a reason not to put in the full 86 gallons besides cost? It would seem to me that the more weight the better. I am wanting to use the tractor to pull a 3 bottom plow, a 9 ft disk, a 2 row planter and a hay wagon. There may be times I want to trailer it to a show, but I don't have a trailer yet, so I would get one capable of hauling it and any attachments I may want to take.
