daveoman1966 3,762 #3 Posted May 26, 2020 Is the cylinder ram moving? If so, then lift linkage is likely the problem. Share this post Link to post Share on other sites

If it is OK then the implement relief valve spring next. Cylinder ram does not move. All linkage is good. Is the implement relief valve spring in the lift control valve or the transmission Share this post Link to post Share on other sites
