This thread is getting off topic, but I just want to add that canola isn't as well adapted to much of the country as sunflowers. Also, while winter canola works well downstate to break up the continuous wheat cycle, it isn't as good of a fit here out west. We don't have a lot of continuous wheat and, as far as I know, winter hardiness is still an issue.
Sunflower gives us another option in the spring, especially in dryland conditions. It works well in our typical wheat-milo-fallow rotation and gives us a way to clean up grass problems that might plague a milo crop. A few local elevators will take 'flowers, whereas the closest delivery point for canola to me is Mooreland. We don't have a lot of on-farm storage and recently we've been storing wheat in our bins during the summer for future marketing.
As for canola being more acceptable than sunflower, well, Frito-Lay is using NuSun oil exclusively for frying potato chips. I've also seen sunflower-based drip oil (irrigation pump lubricant), but I've yet to see anything based on canola oil.
I've only had one fire scare with 'flowers (dust sitting on the PTO housing started smoldering). I keep the machine clean and pay attention to what my nose is telling me. I like 'flowers and I'll keep planting them. I wish I could help these guys with the JDs catching fire, but my lack of knowledge of Deere machines has me stumped. Only thing I can do is parrot everybody else's advice.
