WE have 5 JD 9600 combines, purchased in 1996. At the present time we have replaced the hydrostatic transmission on 4 of them, the 5th one has a reading of about 4500 psi.
WE operate these combine with flotation tires (68-50)on front and 28-26l on the rear. Most of the time we are in 4 wd.Combines have an average 2000 hrs. at separator now.
We appreciate to know if anybody else has axperience the same problem with the hydrostat in these combines after 1500, 2000 hrs of use.
