Assuming this is the 4M40, 50% premixed Mitsubishi Super Long Life Coolant (SLLC) will work fine.
Personally, however, I would use John Deere CoolGard-II in that particular application, a 50/50 mix will work perfect.
Whichever you choose to go with, do a thorough citric acid flush and make sure you replace the radiator cap. Depending on year it will be 0.9 bar or 1.1 bar, make sure you get the correct one.
