Topic: 7000 black belly hydraulicsPosted: 17 Oct 2026 at 2:11pm |

I recently started having issues with my black belly 7000 I use to bush hog with. The first symptom was when I first would start using the bush hog sometimes the pto would disengage when I would shift the powershift. This normally quit after I had worked it for a while. The last time I used it, that was much worse and I wasnt able to raise or lower the wings on the mower. I have plenty of the correct fluid in it (both compartments). It still steers fine. Where do I need to start? Its been a while, but I have adjusted the stand by pressure on the 7060 type tractors but this isn't the same system and im a little fuzzy on the routine anyway. Thanks in advance.

Black 7000 tractors sometimes have the long PTO lever fall into neutral. I always removed the spring inside the PTO valve and cut off one coil to weaken the spring. I'll bet your 1800 RPM red lite doesn't work, correct ??? Fix it. For diagnosing some of your complaints that red lite is needed. Black 7000's also blow a gasket in the PST valve and problems then arise when shifted into the over-drive position of the PST lever. Wing folding weakness must first be addressed by checking the remote outlets max pressure.....should be 2,200 to 2,300 PSI. Check with a 3,000 psi gauge plugged into an outlet coupler.

Thanks for the help. You were correct on the light. Apparently the wire got pulled off sometime... tested by grounding the wire and light came on. Can't verify the sender itself.
You are right on the long lever also, but never had issues with it until now. Started it up and with everything cold, the gauge on the remote showed 2100 or so at 1500 rpm. Didnt rev it up further to see top end and didnt have time to run it much today. The 1800 light did not come on when I engaged the pto, and the pto kicked off when I tried the power shift. The powershift made a grinding noise instead of shifting like it should have. The light didnt come on then either. Not sure what it means when the powershift shift was working fine when it was warm and I shut it down a few days ago but the remotes wouldnt work, and now with it cold im where im at. Thanks in advance. |

Well, it's two separate issues. Remote hydraulics power is one thing. PST/PTO is another. Need more info to diagnose. Take a wire and tie that PTO lever into engagement for now and see how things act when it gets up to operating temps.

I worked it for about half an hour today. Pto would stay engaged while driving, but any use of the clutch or the power shift and it would immediately pop out. I put my hand behind it and it would lightly come back an inch or so when I hit the clutch, then gravity fall from there.
The power shift would make a grinding noise and not do anything for the first 10 minutes of run time. Didnt matter if pto was engaged or not. After that it worked smoothly and held just fine going up and down hills. The 1800 light did not come on at all. The remotes worked just fine the whole time. I did not put a test gauge on again to check the pressure since they worked well. |
