It's been at least five years since I've owned, maintained, and operated my 1660.
I think I'm finally getting everything the way it should be!
It is a lot to learn. When I bought this thing my conventional Gleaner experience had gone back over 40 years. I didn't want to start over, but figured I had to.
Prior owner told me he couldn't get the auto reel speed to work. I have found the same, and just leave it on manual. While working on the turn signals/flashers, on the little console under the steering wheel, I discovered a yellow warning light which indicates when the auger is not in it's cradle. I thought it was funny I had missed it in the manual. So I read it through again. I still can't find it!
