I always used a subsoiler to get below the hardpan and get the soil opened up to the drainage tile. I found that a 3 point, V model John Deere pulled the easiest. The V type have the teeth staggered so they don"t push the soil out against the next shank. The shanks are curved so the point is ahead of it"s mounting so it creates some lift that puts weight on the tractor. I pulled a 7 shank model with 5 shanks with a 4240 with duals at 16". a 9 shank with 7 with a 4640 and an 11 shank with 9 shanks with a 4840. This put the shanks at 30" apart. The tractor needs some speed to keep from heaving and making fields too rough, 4th gear in a power shift tractor worked well for me. I usually went at an angle across a field in 2 directions at 90 degrees to each other. I know some people thought that deeper was better just like plowing but I found that if I plowed at 6-7" and subsoiled at 16" it was most cost effective plus I put my tile at only 30" deep...James
