Mi-T-M CA-4004-1MGM Aluminum Gasoline Pressure Washer – 4000 PSI, 4.0 GPM, 125 lbs
Mi-T-M CA-4004-1MGM — 4000 PSI Direct Drive with Mi-T-M OHV Engine
The CA-4004-1MGM delivers 4,000 PSI at 4.0 GPM through the same corrosion-resistant aluminum platform as the Honda-powered CA-series, powered instead by a 420cc Mi-T-M OHV engine — Mi-T-M's proprietary engine built to the same commercial specification at a lower acquisition cost. General pump, patented vibration isolation plate, and 13-inch flat-free tires are standard across both engine configurations.
CA-4004-1MGM Engine, Pump, and Aluminum Frame
- 420cc Mi-T-M OHV engine — Mi-T-M proprietary commercial-duty engine; same displacement class as Honda GX420, designed for continuous-use cleaning cycles.
- General pump with Mi-T-M Pressure Relief Start — low-resistance start engagement prevents kickback on 4,000 PSI systems.
- Forged brass manifold and thermal relief valve — thermal relief discharges water if pump temperature exceeds safe threshold during extended bypass periods.
- Corrosion-resistant aluminum frame — lighter than steel-frame competitors; patented vibration isolation plate extends bolt and seal life.
- 13-inch flat-free tires — move the 125-lb unit without puncture risk on job sites with nails, glass, and debris.
Contractor and Maintenance Cleaning Deployment
The CA-4004-1MGM occupies the same performance tier as the Honda-powered CA-4004-1MGH but reduces total cost of ownership for fleets where engine serviceability through a broad distribution network matters less than upfront price. Facility maintenance contractors running multiple units split their fleet between Honda and Mi-T-M OHV variants to balance parts-availability risk. Construction and fleet cleaning operations where the unit runs 4–6 hours per day benefit from the thermal relief valve and bypass system that prevent the pump failures common in budget direct-drive machines lacking those protections. ETL certified; 49-state engine — not for sale in California.
