All kinds of equipment can be quickly, easily, and inexpensively converted to clean, green, domestic propane by anyone with basic tools and knowledge of small engines 1-45 hp. ATVs, golf carts, mules, log splitters, generators, power washers, backpack blowers, snowthrowers, string trimmers, leaf vacs, mowers of all kinds, wood chippers...
For more information on all of the benefits of propane as an engine fuel see: AllPropaneMowers.com
So, if you are already running propane mowers or trucks and want to switch over your other existing equipment, this is a great way to do just that. Or, if you want to check out propane as an engine fuel, this is an easy, cost effective way to do so. (The kit can be removed quickly and you're back to the original gasoline engine). You can also run your engine as a dual fuel engine (either gasoline or propane) The kits are transferable to other equipment, only needing a different "adapter block" if it is a different engine type.
Depending on the size of the engine, you can use recyclable 1lb cylinders(available widely at camp, hardware and variety stores), the NEW refillable 1 lb cylinders from Manchester Tank(coming soon), 5-10 lb cylinders, grill tanks or forklift cylinders with adapters.
