You'll definitly need to do something with helicals to harvest edible beans if they are still standard. I would recommend the channel helicals for your crops. Check previous conversation on hyperizing awhile back. Many operators reduce engine RPM to approximately 1900 when doing edible beans. The slower RPM slows alot of things and is easier on the beans, but must have helicals upgraded from stock. Channel helicals with help a bunch with your tough wheat and also with the sunflowers. Good luck
