Kohler’s ECH440LE engine is a modified version of the popular Kohler Command PRO EFI ECH440 with new, lower emission outputs. The engine’s integrated catalytic exhaust system, in combination with its closed-loop EFI system, lowers harmful carbon monoxide emissions by 75 percent without sacrificing engine performance.
Kohler has also embraced alternative fuels with the company’s Tri-Fuel engines. Four Kohler Command PRO horizontal-shaft engines – the CH260, CH270, CH395, and CH440 – now offer the ability to run on three different fuels: gasoline, propane, and natural gas. This advancement allows end users to simply turn a dial to switch between the three options based on fuel availability or fuel preference for a specific task.
