Kansas | I’ve had this tractor and JD air drill for 15 years and it used to work great. Hydraulic capacity seems to be falling.
When I start the tractor it seems the hydraulic pump has lost its prime and I can’t steer. If I drive and try to turn the wheel it will prime itself and work.
We have put a new suction hose on the top side of the reservoir with 2 heavy duty clamps and that doesn’t seem to help.
Was at a medium low idle filling seed with the cart auger and when I hopped in It didn’t have any steering till I moved some.
The 2 filters under the radiator have just been replaced with the same kind I have always used.
Do I have a priority valve or something not working? Or do I have a pump or 2 going bad?
15 years ago I could run the fan at 5,000 Rpm. Last couple years 3,700 rpm is the most I can get out of it. Today it is raising the drill much slower.
1998 model with 8,300 hours. Been on an air drill most of its life.
