Subject: 8430T Hyd oil level low (but its not) shuts down flow


New to us JD 8430T showed up. Hooked up to air cart and run thru some checks. Immediately the hyd warning came on low oil and shut off flow. It wasnt low, and what little time we ran it we could not get the fan RPM to be where we needed it to be and the little New Holland TG 210 would. We looked the tractor over and found a transmission sensor about at the full oil level and unplugged it. Cycled power and ran the hyd again. It gave us a diff hyd general warning but the circuit never shut off and the fan RPM was close to be where we could run the fan but at "10" max flow. At about 9 the fan RPM stopped going up anyway.

The tractor had its oil changed and filters (1500 hour service) it appears right before we bought it. So i assume that since the dealer did it it had the pick up screen cleaned but who knows...

Edit note: It will also shut off on a diff circuit running an empty cart fill auger and a less flow demand. So dont think its related to the fan or case drain circuit I

Any ideas?? please and thanks
