Mi-T-M CBA-3504-1MAM — Belt-Drive 3500 PSI with Mi-T-M 420cc OHV Engine
The CBA-3504-1MAM pairs the CBA aluminum belt-drive platform with a 420cc Mi-T-M OHV engine — the same proprietary commercial-duty powerplant used in the CA direct-drive series but mated here to a belt-drive transmission for lower pump speed and extended seal life. AR pump, patented vibration isolation plate, and 13-inch flat-free tires are standard.
CBA-3504-1MAM Mi-T-M Engine and Drive System
-
420cc Mi-T-M OHV engine — Mi-T-M proprietary commercial-duty engine; same displacement class as competing 420cc engines at a lower acquisition price point.
-
Belt-drive transmission — operates pump at 60–70% of engine RPM; reduces pump temperature and extends seal life versus direct-drive equivalents.
-
AR pump with Mi-T-M Pressure Relief Start — 3,500 PSI output; adjustable unloader sets working pressure without nozzle changes.
-
Forged brass manifold and thermal relief valve — corrosion-proof manifold; thermal relief protects pump if trigger is held closed for extended periods.
-
Corrosion-resistant aluminum frame, 165 lbs., 13-inch flat-free tires — aluminum construction reduces loading effort versus comparable steel-frame units.
Commercial Cleaning Applications at 3500 PSI
The 3,500 PSI range is the commercial sweet spot for surface preparation, concrete cleaning, equipment degreasing, and fleet washing where the higher cleaning force of 4,000+ PSI can damage softer surfaces. Restoration contractors specify 3,500 PSI for brick and mortar cleaning where excess pressure causes efflorescence erosion. Property maintenance companies use the 3,500 PSI class for parking garage floor cleaning, loading dock scrubbing, and dumpster pad maintenance. The Mi-T-M OHV engine option offers cost savings for operations with large fleets where proprietary engine parts procurement is centralized through Mi-T-M's parts network. ETL certified; 49-state engine — not for sale in California.
