For a full size Zero turn you would be using 2 tanks that would carry a little under 15 gallons which translates to 12 gallons of gas correct?
Currently I'm buying propane at $1.99/gal for my house (200 gallon min though). That equates to $2.40 compared to my current price of a gallon of gas.
On tank exchange programs what is a average charge per gallon delivered? or picked up? I know this is location driven also but there needs to be a national average out there. When I called the local company they don't have a exchange program but could fill the tanks up. I didn't call any more places at the time.
On your calculator it showed a maintence savings about twice as much as fuel savings. In my case looking at 1 mower it was $800 in that year. I don't know how you figure this but skeptical on that figure.
How much does a double tank kit weigh?
It sounds like if gas is over $2.40/gal at my current rates there could be a savings, after it pays for a conversion kit.
Actually propane has about 7% fewer BTUs than gasoline but runs a more robust 104 Octane. Typically usage is close especially given shrinkage.
Fuel pricing differs per region because of transportation costs. It's up to the Districts as far as pricing is concerned. I believe a savings of 15-20% is built in to the calculator. Many do much better than this. After hitting "enter" you can input your current local pricing to get a better idea of savings.
A full 33# alumninum cylinder weighs about 55# and carries roughly 7 gallons. Propane weighs about 4.24# vs gasoline at about 6. Brackets are around 5-7. It depends on the mower whether or not two tanks would be mounted. Sometimes we get a day out of one 43# tank. We try to match the OEM operating time.
