LEHR Propane Fuel Systems on the LX600 are certified 53% cleaner emissions than the closest engine in its class according to the Environmental Protection Agency. Standard low tone catalytic mufflers reduce carbon monoxide emissions well below OSHA permissible exposure limits. SAM Safe Air Monitor further increases safety by alerting operators should carbon monoxide levels climb to unsafe levels and will automatically shut engines down to prevent injury.


LEHR Propane Fuel Systems use a patented variable venturi and fuel jet design which never comes out of calibration and requires no field adjustments. LEHR systems utilize a three- stage pressure regulator that vaporizes any liquid propane caused by overfilled cylinders or use of liquid cylinders making the LX600 the safest and most reliable engine in its class.


Heavy-duty piston rings, a cast iron cylinder liner, and hardened heads designed for propane fuel resist wear and ensure precise timing for long engine life in commercial and industrial applications. Our heavy duty, low tone catalytic muffler is supported back to the engine block with two brackets and lasts the life of the engine.
