I have a 2WD Massey Ferguson with a 2-Bottom Plow. I planted Sorghum-Sudan seed early in summer and it has been cut down twice. Now trying to Plow it. My draft control does not work on my tractor. 1) when I start to plow, my wheels start to spin and I need to raise the plow constantly. 2) with this cut Sorghum-Sudan seed, when I try to plow, besides my wheels spinning, the grass just builds up a large plug on my plow. Do I need to move my coulters back or sharpen them? How do I get me wheels to stop spinning? Any suggestions greatly appreciated!
