Tech at a Deere dealership just got back from school. He said that he was leafing through a handout and he noticed electrical diagnostics for self leveling sieves and for a folding corn head (09 MY?). Has anyone heard of Deere coming out with either of these? He also said the 9870 5 spd header drive was rated for 300 HP. How many HP can it take to run a head?

Self Levelling Shoe is part of the 2009 Updates. I believe the ProDrive Transmission is as well. Not sure if the folding corn heads will appear for 2009, but I know they are working on them. Deere likely wants to run the new 600C heads a bit more before deploying the folding versions.

JD has had a folding corn head in Europe for awhile. It is the CornStar. It has different row units than the US corn heads. Hear that it works good in really wet stalks, but doesn't handle dry, brittle stalks as well as the US row units, which is the main reason I hear that it isn't in the States. Probably standardizing wiring, which is why it shows up in the Tech Manual.

Pretty sure a ProDrive Transmission is in the forage harvesters now. Basically an automatic powershift. Think they need to figure out weight transfer and hills to get it right on the combines. I kind of like the transmission we have now. Simple, reliable, and gets the job done. Also not an expensive thing to fix if you have to ... as opposed to powershifts.

Here's a link to a brochure out there on "foreign" JD combines, which includes a blurb on the CornStar on page 3 of 15. (Needs to be opened with internet explorer . . . firefox doesn't seem to want to work with it.)
