Hello everyone, while we are on this subject, The wheat in the "thumb" of Michigan is about ready. It is supposed to rain this weekend (lord knows the weather personal not always to be right!) so I hope the comes down nice, we could use some, just as long as we don't get hail! Anyways, I am going over our 1660 for the last time before wheat and I had a couple of questions as well since this subject was brought up. We ran this machine in soybeans last fall so that was the last crop to go through it. We combined wheat last spring with it (did a nice job) and I can't find the settings that I wrote down, but I know the manual was close. My questions are: 1.) What position should the drum stop be in, top, middle, or bottom, for wheatIJ It is in the middle now. 2.) Also, the block that stops the feeder drum from going up (rock protection) is in the lowest position (max. rock protection) and I was wondering if it is necessary to let it "float" more for wheat, or if it will work good thereIJ 3.) The rotor belt has a slight crack in one spot and I was wondering when everyone determines when to replace their rotor belt. I think that is about it for now! ;-) Thanks.
