JD 317; replaced hydraulic hose; now no hydraulics

[MRR]

Replaced hoses to drive motors. Now there is no response from any hydraulics. No boom or dump control, no auxiliary, no forward or reverse. Tank is full.

Don't run it. Loosen some hoses and see if there is fluid there. JD should have a procedure to bleed and prime everything.

Thanks and I will try that tomorrow

check the park brake switch and the seat switch.

John Deere does have a procedure to bleed hydraulics. Loosened all the hoses one at a time until fluid flowed. The larger hoses to the drive motors seemed to get the best results. After that, cranked it up and we were back in business.
