The Case is a proven machine with very good reliability. Fairly easy and forgiving to set also. The Deere STS, my experiences as well as other custom guys I've spoken with, is quite difficult to set to do the same job as the Case. Also has a lot of reliability bugs to work out yet. Not trying to bash Deere, but they tried to reinvent the wheel and made it WAY too complicated. MHO is they should have learned from Gleaner and Massey that simpler is better. The R62 will outperform both the Case and the Deere too in power, capacity, grain quality, and losses in the majority of conditions. You are doing yourself a disservice if you don't consider it unless your dealer is too far away.
