Forum:Harvesting ribbon?

I have all this fuel from the new method of fuel-collecting on Farmville (which I was initially against but I love it now), and I'd like to use it on my Harvester, but I'd also like to be able to save it for a potential new Harvesting ribbon, and I was hoping this question might spur that forward with the powers that be, because what's the use of having plowing and seeding ribbons without harvesting ribbons?
