I think that it would be great if we could see alternative fuel choices rolled out at GIE this month! The technology is in place, and has been for MANY years, to run most fossil engines on propane and cng. If they were on cng, you could have a generator station at your home, filling up your own tanks before going out for the day! MUCH cheaper than gas or diesel, and the pollutants could be 1/2 or more less than gas or diesel. I know that Dixie Chopper and Ferris are currently leading the pack on these types of mowers... so what is everyone else doing?? I'd love to see a Walker, Wright or Hustler on propane or cng!! I would pay a higher price for the equipment, but if everyone started to do this, that cost could come way down! As an industry, let's help out with the pollution issue... and go "green-er"!!
