Good Morning Everyone. I have recently purchased a hydraulic dump mcs that I would like to mount on my 420. I am new to mcs ownership so I have never mounted one before. My question is this. I have three point on my 420 and do I have to change my three point rockshaft back to the original rockshaft or will it have enough clearance to leave the three point rockshaft in place? I am finding conflicting information on this so am just trying to save myself any extra steps. I have two mcs owners manuals and one say to change back to original and one does not. If anyone has any experience with this I would greatly appreciate your input. Thanks in Advance. Scott.
