Mi-T-M CBA-3504-1MAK — Belt-Drive 3500 PSI with Kohler CH440 and AR Pump
The CBA-3504-1MAK matches the aluminum-frame CBA belt-drive platform to a 429cc Kohler CH440 OHV engine — an alternative to the Honda GX390 in the same displacement class with Kohler's commercial-service support network. AR pump, forged brass manifold, thermal relief valve, and patented vibration isolation plate are standard across the CBA series.
CBA-3504-1MAK Kohler Engine and Belt Drive Configuration
-
429cc Kohler CH440 OHV engine — Command Pro series horizontal-shaft commercial engine; cast-iron cylinder liner, full-pressure lubrication, 100-hour oil change interval.
-
Belt-drive transmission with two-piece belt guard — runs pump at lower RPM than engine; guard protects belt from debris and water ingestion.
-
AR pump with Mi-T-M adjustable-pressure unloader — consistent pressure output across varying flow demand; Pressure Relief Start for easy engine cranking.
-
Forged brass manifold and thermal relief valve — brass resists corrosion from detergent chemistry; thermal relief activates before pump damage threshold.
-
Corrosion-resistant aluminum frame, 13-inch flat-free tires — 165 lbs. net; flat-free tires eliminate puncture delays on debris-strewn sites.
Applications for Kohler-Powered Pressure Washers
Buyers choosing the Kohler CH440 over Honda GX390 typically cite Kohler's dealer network in agricultural regions where Honda service may be less accessible. Farm and ranch operations running livestock facility washdowns, grain bin cleaning, and equipment degreasing value the CH440's cold-weather starting reliability and full-pressure lubrication system. Industrial cleaning contractors serving Midwest and Southeast markets often standardize on Kohler engines to simplify parts procurement across their entire fleet. The 3,500 PSI / 3.7 GPM output handles concrete pad cleaning, mold removal, equipment surface prep, and vehicle fleet washing without a pressure step-down. ETL certified; 49-state engine — not for California.
