2 Stage Canister Air Filter for a Kohler 7000 Series (KT725)

Hi folks,

I'm wondering if anybody has heard of or has themselves retrofitted a 2 stage canister air filter to a Kohler 7000 Series? I have access to two free canisters one a Nelson and a Donaldson parted off my brothers ZTR's-I apologize in advance as I don't have the specific model numbers yet. The Kohler is on a Scag Freedom Z... thanks in advance for the comments

Mike
