The combine has power steering, Hdy variable reel speed, and Hdy reel height control. The reel speed and height controls work fine when just starting the machine, but after about an hour of running the controls get slower and slower until they will not respond. The power steering, header height and variable speed still work. I can spray water on the Hdy pump and the reel speed and height will start working some, but very slow, and will eventually stop working again. Is this just worn pump or could it be something else? The Hdy filter and oil was changed, but the problem is still there.
thanks,
Robb

sounds like it's heating up. I don't have power steering on mine. might be sucking air or getting air pockets in it

Look for a clogged oil cooler. It may just need to be washed out. Are you using type A transmition oil?

Since header lift and traction drive variable speed works I might look at the control linkage. Something may be bent worn are lost .
There are two hydraulic circuits that dont work properly but there both activated by same lever in cab.

My guess: Hydraulic pump and/or hydraulic flow control valve is(are) worn or internally cracked. When the combine is initially started, it's hyd oil is cold and thicker so the worn or cracked part('s) leakage is less noticeable. After the hyd oil heats up, leakage volume increases.

common, replace the pump. Also remember - keep those header helper springs as pushed up tight as possible.
