Mi-T-M CBA-4004-1MAK — Belt-Drive 4000 PSI with Kohler CH440 and AR Pump
The CBA-4004-1MAK delivers 4,000 PSI at 3.4 GPM through an AR pump belt-driven by a 429cc Kohler CH440 OHV engine. Functionally equivalent to the Honda-powered CBA-4004-1MAH, the 1MAK substitutes Kohler's Command Pro series engine for buyers who prefer Kohler's commercial service infrastructure or who standardize their fleet on Kohler powerplants.
CBA-4004-1MAK Kohler CH440 and AR Pump Specifications
- 429cc Kohler CH440 OHV Command Pro engine — full-pressure lubrication, cast-iron bore, commercial duty cycle; Pressure Relief Start standard.
- AR triplex pump at 4,000 PSI / 3.4 GPM — forged brass manifold; Mi-T-M adjustable-pressure unloader; 13,600 cleaning units output.
- Belt drive with two-piece belt guard — pump runs 30–40% slower than engine; guard protects belt from water, debris, and chemical splash.
- Thermal relief valve and clear-sleeve water filter — automatic pump protection and quick-inspect filter maintenance.
- Corrosion-resistant aluminum frame, 165 lbs., 13-inch flat-free tires — lighter than steel-frame competitors; flat-free tires prevent site downtime.
Industrial and Commercial Cleaning at 4000 PSI
The CBA-4004-1MAK handles the same heavy-cleaning roster as other CBA-4004 variants: graffiti removal, paint preparation, rubber-deposit stripping, concrete residue cleaning, and heavy equipment degreasing. The Kohler CH440 engine choice specifically benefits agricultural users, rural contractors, and Midwest-based maintenance fleets where Kohler's extensive rural dealer network reduces engine service lead times versus Honda. The CH440's full-pressure lubrication system also performs more consistently in cold-weather starting conditions common in northern climates. ETL certified; 49-state — not for California.
