I'm trying to figure out the AMX, AM1 difference. My dealer is telling me that Acre Max Extreme? is 2 modes of action but of what? I am not trying to make this a DKC vs Pioneer, just looking for some clarification and help on these. Also trying to determine if I even need a refuge if I plant these Acre Max hybrids on some of my ground, some Smartstax RIB, and some VT3 RIB, or do they take care of their own refuge? THANKS for the help.
