I have a 3020 Powershift with a loader on it. The other day we were using it and sprung a leak in a hydraulic hose and didnt realize it until the tractor stopped moving. We shut it down and pulled the TOW lever on it to get it loaded on a trailer. Once we got it home we replaced the hose and then filled it back up with hydraulic oil and put the tow lever back in the run position. Now the tractor won't do anything hydraulic related. The transmission won't build pressure, the loader won't lift, no steering, nothing. I was wondering if the transmission pump could be air locked and need to be bled or did something let go in there. Thanks in advance for any help.
