I have a new set of cart link arms to replace the link arms between the Great Plains air seed cart and drill. This fits the 2220 and 2250 carts and ADI345 drill. Factory part number of 160-076H, which is obsolete and no longer available. May fit other models of carts. I have built these for several customers, finding that this is a weak link in the operation of this implement. I fabricate these from heavier material, the factory link arms are made from 4"x4"x3/16" square tubing, I use 4"x4"x3/8" sq tubing.  I also replace the 1-1/4" shaft on the drill side of it with a 2" 1018 shaft, and 1/4" wall bushings. The cart end of the arm has a thicker bracket for the larger than OEM weld swivel. I have pins and bushings to rebuild the cart hitch boxes as well. This kit will need to have larger bushings fit and welded in to the frame of the drill. I can install these in the field or sell you the kit to DIY. Installation is not included. The kit includes both arms, 2" shafts, bushings for the drill frame and a retaining bolt for the shafts.
