A self own, an in the field adaption, and a question.

[BobbieNicole]

I was digging a hedge out of short rocked wall terrace with the back hoe, of course there was a lot of bouncing and sliding into and onto the wall. Finally admitting that I had done what I could, I tried to leave, but found myself hung up on the rocks by the backhoe mounting flange. 4WD didn't seem to help and the rear tire(s) were spinning. I tried to use the diff lock, but didn't help so I disengaged it---or so I thought, turns out I disengaged the PTO. I was way tired, (end of long day), but I did check the 4WD and reengaged it and got myself free, but now the backhoe was dead---this is the self own ( I disengaged the PTO pump!). I tried to use a rachet strap to pull up the backhoe, but attaching it the roll bar didn't work, nor did attaching it to the loader while it was on the ground. So realized if the loader was full height, I could rachet the backhoe into a stowed position. As I was ratcheting I realized if I lowered the FEL it would pull the backhoe up; two iterations later, done. The next morning, after a good night of sleep, while watching the Keno video of how to remove the backhoe, the fellow mentioned PTO and I realized I had disengaged mine, so feeling both stupid and relieved.

I always leave my PTO engaged because the backhoe is droopy and swings a bit if there is no pressure. So the question is, is there anything wrong with leaving
it engaged?

Sounds like a mess! Good luck.

You may have missed the "self own" part, the back hoe died because I essentially turned it off without realizing it---all better now.

Glad for you all is good.

Don't understand how leaving the PTO engaged helps stabilize the backhoe. You're not the first person that has stated leaving the PTO helps.....something, last one I read was stopping the bucket from falling or something similar. The oil is basically circulating from the pump, into the P port thru the valve body out to the T port and back to tank. The working ports both A and B should be blocked, other than minor leakage, when not operating and should not see any flow from the pump or return flow from either port.. I'm not including a motoring spool here, just a regular spool.
I'm talking an open center valve, (which I presume yours is) conventional gear or vane pump, not a closed center variable displacement pump. What am I missing?

Missing the part I neglected to say (oops), where I reach back, raise the bucket, then swing it back and forth a bit and return to center. So in addition to stowing it back to where it belongs, the pressure in the actuators is re-established. Of course, it immediately starts to bleed off through whatever leak it has found, but the clock is reset. I leave the PTO engaged so that I don't have to engage it each time, I am aware it doesn't pressurize the actuators without me moving the levers. I'm hoping the continual fluid loop isn't detrimental.

I try to not leave the PTO driven pump running any more than necessary. I think that it is just adding to the wear of the pump, heating of the fluid (wear) and powers up an implement that could have an accidental control input of failure of another kind.

That being said, if I am just moving the hoe from one set to the next, I leave everything running.

For longer moves I use the boom locking pin, a chain from outrigger to outrigger (they leak down) and a chain from the bucket to the boom keeps it in place.

Fortunately I haven't had the problem of the boom swinging on it's own. If that was a problem I would probably use chains or straps from the bucket to the outriggers. Perhaps some kind of locking pin...

As hindsight, when you were hung up on on the rocks you possibly could have used the backhoe to get over them. Sometimes that works, sometimes it doesn't.

Ahhh, that makes more sense now, thanks.

When I had my Chinese tractor and backhoe, that's what I'd do as well.

Many tractors, including my Kubota's, have a lockout switch and won't start if the PTO is engaged.

I do have the back hoe tie down chains still attached to the base---I'll probably do that and then not leave the PTO engaged.
