Diesel Engine

John Deere Interim Tier 4, turbo charged, intercooled, six-cylinder, liquid-cooled diesel engine provides ample power to operate
the generator continuously at full-load. It meets all US EPA, CARB and Environment Canada exhaust legislations with interim Tier 4 compliance. The engine utilizes a Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) to meet interim Tier 4 emissions. All functionality of the engine is controlled automatically on the DeepSea 7310 controller.

The engine has the capability to start the generator at 14°F (-10°C) with standard glow-plug aid. Cold start options are available for machine
starting for down to -13°F (-25°C). Comes standard with 120V immersion block heater. The 450 Gal (1703L) fuel tank is sufficiently sized to operate the unit at full-load condition for long run times. John Deere Interim Tier 4 engine operates on a 24V negative ground electrical system with a 100A charging alternator and lockable battery cutoff switch. The cooling system is suitably designed for continuous operation in ambient conditions up to 122°F (50°C), with canopy door closed.

Horton Generator Power Panel


DAE Pumps Horton 250 power generators use alternators built for heavy-duty continuous application with marine winding protection. We use Leroy Somer alternators with AREP excitation systems for superior starting capabilities. The AREP system uses two independent auxiliary windings located in the main stator to send supply voltage to the AVR.

Control System

The Horton 250 control system uses a fully diagnostic DeepSea 7310 ECU controller with a large 3-inch display, that is intuitive and easy to operate with all functions conveniently at your fingertips. The controller manages the engine ECU operating system and several safety warnings and shutdowns on various parameters.
