So why would anyone want to convert a perfectly good gasoline engine to propane? There are a few good reasons, which we'll go into here. First, though, I want to put out the standard safety and disclaimer information that anyone who wants to start this conversion should know.

Propane is a flammable gas under pressure. Observe all manufacturer recommended safety precautions as seen on the propane bottle while completing the installation of this kit. Check for leaks before operating the mower using a soapy water solution. If you are operating the mower and smell propane, immediately shut off the engine and leave the area. Propane is heavier than air and will pool in low areas, which can cause flash fires or explosions. Work on this conversion outside and do not store the mower inside with a propane bottle attached.

Converting a lawnmower or other small engine fuel system may be illegal in your area, especially in parts of California. As the effectiveness of the conversion process relies solely on the skills of the installer, no guarantees are expressed or implied as to whether or not your results will be the same as the results shown in these plans. Furthermore, as material quality varies greatly between manufacturers, there are no guarantees that the conversion process will be the same or similar because of the materials sourced and the methods of installation. All gasoline to propane conversions are undertaken at the user's own risk.

Benefits of Propane as a Small Engine Fuel:

Propane as a small engine fuel provides a variety of advantages over gasoline. The environmental advantages alone make a propane conversion worthwhile; however it is important to note the other benefits of a propane-powered lawnmower.

1. Storability — Propane does not go bad and can be stored indefinitely. Modern gasoline, on the other hand, has a shelf life of only a month or two without stability additives, and even then cannot often be stored longer than six months before degrading.

I used the plans at WWW.EASYWOODWORK.ORG to build my own – I highly recommend you visit that website and check their plans out too. They are detailed and super easy to read and understand unlike several others I found online. The amount of plans there is mind-boggling… there’s like 16,000 plans or something like that for tons of different projects. Definitely enough to keep me busy with projects for many more years to come haha. Go to WWW.EASYWOODWORK.ORG if you want some additional plans :)
