Command PRO EFI ECH980

You got jobs that need some muscle? You're in the right place. The Command PRO® 999cc engine redefines the standard of power and reliability. We overloaded this beast with horsepower and torque to take on any obstacle. And then engineered it with heavy-duty sleeve bearings for extra protection and lasting durability.

  • Fully integrated oil cooler extends engine and oil life
  • Robust torque output handles the toughest commercial applications
  • Hydraulic lifters mean zero maintenance on the valve train
  • Easy routine maintenance and service
  • Saves significantly on fuel, with less downtime for refueling*
  • Advanced sensor technology allows engine to optimize performance by automatically adapting to operating conditions
  • *Compared to a comparable KOHLER carbureted engine under comparable loads and duty cycles

Length is front to rear of engine. Width is valve cover to valve cover. Height is mounting surface to top of air cleaner.

1 Power (hp) and Torque (ft lbs) specifications for Kohler general purpose engines are rated pursuant to Society of Automotive Engineers (SAE) J1940 based on gross output testing performed according to SAE J1995 without the air cleaner and muffler. Actual engine power and torque are lower and affected by accessories (air cleaner, exhaust, charging, cooling, fuel pump, etc.), application, engine speed, ambient operating conditions (temperature, humidity and altitude) and other factors. This J1940 / J1995 rating provides consistent measurement to customers who may want to control the intake and exhaust features of the engine. For more information, contact Kohler Co. Engine Engineering Department. Kohler Co. reserves the right to change product specifications, designs and standard equipment without notice and without incurring obligation.
