I googled Wix filters and clicked filter lookup. The Donaldson number crossed over to Wix 46496. It showed all the measurements, specs, and that it was used on Kubota engines. They did not list an air filter for your CC, but did have the oil and hydraulic I think. I then entered your Mitsubishi part number into their crossover search and hit dead end. They did however ask for the application and I gave them info on your tractor, engine make and size, etc. They might come up with something.
