For the sun to shine . Put new points on the tool carrier front row of shanks and the rear two rows of shanks will still have 14 and 16 inch wheatland sweeps I run chisel points on the front so it will go in the ground When it?s hard and sweeps in the back so it will turn more dirt . Also put the Cummins 53 block repair to the test hauling the tractor and drill got everything good and hot still no dye showing up with the uv light time will tell but I don?t think it?ll crack again It cracked at 270,000 miles probably a little before that it now has 302,000 on it and it?s Bren cracked for over a year
