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. PSI, GPM, and physical dimensions are identical to the 1MCK model at 156 lbs and 47″ × 27.5″ × 28.5″.
