I have a 40 FT 2005 Great Plains Drill model # 3S-4000-HD for sale. Drill is set up at 7.5" spacing and has brand new discs on it that have never touched dirt. We went throught and had all of them replaced 2 years ago and we havn't had the drill out since. When the discs were replaced we had them put a new hitch clevis on because it was getting a little wallered out, so it is brand new also. It also has an electronic acre meter mounted on the drill and it is showing that the lifetime acres for the drill is 8506 acres, so it hasn't been over to much. When we had the discs replaced we had them put a blockage system in the drill with its own monitor that is all brand new also. This is the heavy duty version so has heavy duty ribbed wheels, etc. Also, it has been shedded its whole life so the paint looks good and you wouldn't be able to tell the difference between this drill and a brand new one. If interested, have questions, or wanna make an offer give me a call at 785-534-0132.
