im guessing this might be just a cool gimmic, ice augers are the same way.why use propane vs gas??
isnt propane more expensive than gas per KWH... Albeit its probably also less efficient....
1 gallon of gas 33kwh - 2 dollars to 3 dollars
1 gallon of propane - 27kwh - 2.87 dollars per gallon refill at Tractor Supplies Website
But But But..... a 20 gallon propane tank is not completely filled to 20 gallons due to some weird law i guess. So take off 10% of the 27kwh and now your done to 24kwh.....Gasoline way way is cheaper per energy unit and engines are optimized for gas...
only advantage i see is that you can store propane pretty much indefinitely, and it doesnt gum up carburetors if left for a long time.
as well as no fumes if stored inside.
you can refill your own tanks for a lot cheaper, ive done it plenty of times. i go to a local supplier (tractor supply is overpriced in my area)
and its about 1.00$ a gallon im 100% sure there just a employee using the bosses tank to get some $ but hey, its cheap for me!
