Mi-T-M OHV Engine in Commercial Field Use
The Mi-T-M-branded 420cc OHV engine is built to the same specification as the CH440-equipped variant. The Mi-T-M engine option is commonly chosen by buyers who prefer parts sourcing through a single manufacturer (Mi-T-M) rather than managing separate Kohler and CAT service channels.
