6 cylinder water cooled diesel engine, outfitted with a residential grade silencer, rated for providing a mini- mum of 150 continuous HP at 1800 RPM. Engines can be Cummins, John Deere, or Deutz. This is a customer prefer- ence.
Independent open-center circuits allow simultaneous pump, cutterhead, and traverse operation with variable speed controls. Hydraulic pump is a Commercial Intertech or equivalent with two stages, producing a hydraulic oil flow of 0-100 GPM. Each circuit is controlled via electro-hydraulic proportional valves. Each circuit has independent relief valves. System oil is cooled using a Thermal Transfer in-line oil cooler. All hoses and fittings are Parker Hanni- fin.
Heated and cooled control cab with 360° visibility, and adjustable operator’s chair with Electro-hydraulic joystick controls. Dredge systems readouts and alarms, operation gauges maintained in clear view.
