Kubota 3C581-72100 A/C Evaporator – M100 to M9960

Your Kubota M-Series tractor’s A/C isn’t blowing cold — or the system is losing refrigerant charge with no obvious external leak. A failed evaporator core is a common cause across the M-Series lineup. This direct-fit aftermarket evaporator replaces OEM part 3C581-72100 and covers one of the widest fitment ranges in the Kubota M-Series catalog.
