hey whizz.....ive got a 850 that was doing the same thing in wheat harvest last year....a dealer told me to take apart that black box that is just in front and to the left of the front access to the motor....(it is a box with several valves in it....it is the one that controls how fast or slow the header comes down such as when you change to a heavier head it will come down to fast...discusses that in owner manual)take all the valves and valve bodies out and clean them and blow them out with air....i did not see anything obstructing but when i put it back altogether it worked fine....there are very small openings in those orafixes...hope this helps.....
