New Liquified Petroleum Gas (LPG) conversion kits make it possible for Exmark customers to operate three of the company’s lawn mower models with propane, a clean-burning fuel that produces lower emissions than gasoline.
Conversion kits are available for:
Turf Tracer HP (THP19KAE483 or THP19KAE523)
Turf Tracer (T23KAE with FMD 604)
Lazer Z AS (LAS28KA604)
To ensure the safety and high performance of the mowers, Exmark will install all conversion kits at its headquarters in Beatrice, Neb. Customers interested in LPG conversion should visit their local Exmark dealer, who will coordinate shipping and logistics.
Development of the LPG conversion kits is the latest example of Exmark’s commitment to offering environmentally-friendly products. In October 2008, Exmark announced that all 2009 model year diesel-powered Lazer Z XS mid- mount zero-turn riding mowers (serial #790,000 or higher) are approved to use B20 biodiesel fuel.
“More and more, landscape professionals are taking actions to reduce their impact on the environment. At Exmark, we have a similar focus,” said Mark Stinson, president of Exmark. “We feel strongly that it is our responsibility to provide products that are environmentally responsible, yet still offer our customers maximum performance.”
Propane has been approved by the Environmental Protection Agency and the California Air Resources Board as a clean alternative engine fuel. According to the Propane Education and Research Council, propane’s octane rating is 104 (compared to premium gasoline at 91-92), allowing for a higher compression ratio in the engine and greater engine efficiency. This ultimately leads to reductions in certain exhaust emissions, such as carbon monoxide.
In addition, propane is a naturally stable fuel and can be stored for long periods without going stale or varnishing within the carburetor.
Using propane does not negatively impact mower performance. The clean- burning fuel results in fewer carbon deposits, leading to reduced engine maintenance costs and longer engine life. Run time is similar to gas-powered mowers.
Exmark’s LPG fuel system is designed to conform to National Fire Protection Association (NFPA) 58-2008 Liquified Petroleum Gas Code for safe operation.
