Does anyone have the majic numbers to set up the John Deere AutoTrac Universal on a JD 4850 MFWD tractor with saddle tanks pulling a planter?  The numbers from Deere will not keep it from wondering.  If it was pulling something hard and front end was lighter Deere's numbers would probably work.  Signal is not a problem sicne running RTK and all seems to be working well in that area on this tractor as well as 9420 with autosteer (built in).

Someone in the valley had some other numbers that seem to work better but are not in the "range" that Deere says to be in.

Anyone else have this problem?
