djagusch- We are in the same boat as you. Went to the green expo talked to the Minnesota Propane council about converting over to propane. Just like others have stated the cost of a new propane mower is about $2500 more the a gas powered engine. I was told I could use my house propane tank as a refueling station. Just needed to purchase a pump to fill the mower tanks.
The biggest concern I have is the liability insurance of the filling station and employees filling these tanks.
I would like to know what the weight difference is from a propane mower compared to a regular mower.
If someone has a difference experience from what I have wrote please pm me.
