I just purchased a new to me 2003 Deutz MK3 150 and I can't seem to get both of the 3 pth to work. Is there some sort of lockout sequence I need to activate them? The rear 3 pth works perfectly using the outside fender ground controls. I have a 2009 Deutz M650 and just recently figured out the sequence to lock and unlock the 3pth controls but this MK3 150 is different. Thanks for any help.
