I had noticed in the past the stabilizer lever not always returning to the center position but the stabilizers worked OK so I ignored it. Never again! Should I look into that control system to see if anything needs lube? The tractor lives in its own garage so this didn't happen due to weather...

Dan deserves a special kudo for not dumping on me for confusing open and closed hydraulic systems.

Dan strikes again!! His star shines bright. FWIW, my mobile mechanic totally missed it and when he consulted with several friends who are dealership mechanics, some with decades of experience, none suggested this as a possibility. Dan's idea to directly test the PB circuit was key. Of course...

Dear Exalted Guru, you did it once again. Just like people say on the forum. One of the stabilizer levels was stuck partially engaged. When I released it there was an immediate reduction in engine load. AND BOOM WORKS. Thanks so much!! FWIW, my mobile mechanic not only missed it but his...

I will do that right now before granddaughter comes.

OK, will put lines back. One of my granddaughters comes to visit at 11 today and that takes priority over everything else. I will be back with wrenches mid afternoon. BTW, she just finished her first year at Georgia Tech so she might enjoy hearing about this mess. She's not in ME, but still.

The impossible happened. Absolutely impossible. Routing PB from the loader spool valve directly to the hydraulic block tank port completely restored the loader boom operation. This happened despite it not working when connected to the PB circuit that we know is clear because the backhoe...

OK, wilco - tomorrow

I had not seen your last reply when I last replied. Would removing the backhoe and linking hoses work as well?

I wasn't thinking that removing the backhoe leaves the lines to be connected easily - biting head to tail for both the tractor lines and the backhoe whips, something you do when you take the hoe off. I have never taken this backhoe off before, but I know in general how to do it. Might as well go...

I'm willing but am losing light tonight so it will be tomorrow. I know where the tank hose connects to the backhoe, but not where to connect it directly to the tank. Any advice would be appreciated. On thinking a bit more, I suppose the place is where the other backhoe hose connects to the body...

That sounds a lot like the fault lies within the spool valve.

BINGO!!! So smooth! Unfortunately, that's not a movement I would ordinarily do when using the tractor for work. What does it mean??

That I have to test. Will be back with results in a few

BTW, I have been setting the torque to 30 pound feet for the male quick disconnects. Does that sound about right? I know too much torque can damage the mating surfaces and too little causes leaks.

Sometimes the raise function had been weak - jerky even. I can go reconnect the female fitting and see how the raise function is doing. Because the only way to lower is with the float and that pretty rough, I had not been testing the raise function much recently.

No. It's the down function that no go. I think I posted that in the beginning. Recently pushing the joystick forward which should lower the bucket instead raises it. That didn't happen at first but is happening now. Now do I do the same test but with the yellow labeled quick connects?

Do remember that the raise bucket function was working more or less. It is the down function that fubar. Allen

Sure, ready for another step. Hope it doesn't give me a hydraulic oil shower but am so frustrated I will risk even that !!

Sorry for the double answers. After posting I did not see my first answer so assumed it went to bit purgatory and answered again.
