Ive been thinking a lot lately with the new going around about gas prices going up to $ 5.00 a gallon by summer 2012. So I've been really thinking on other ways to save money and stay ahead of my competition. I was wondering if any one has used either exmarks propane mower or their EFI mowers. I was wondering how you guys liked them and how they worked if they were just like gas mowers. Im going to talk to my dealer some time this week to maybe demo one.
