Help - Hydraulic hose will NOT come off

[beowulf]

tcreeley, yours is an interesting analysis - and you may have found the answer. Like you, I have also seen posts by some who do not have a problem back dragging while others do. I got away with back dragging at severe angles quite a few times. Sometimes I just could not resist doing it when it was the perfect solution to the task at hand - and when I did not have access to all sides of the work I was tackling. I would think, well, maybe I can do it this one time and not have an issue. But, twice while back dragging in a major way (i.e., to dislodge boulders) I blew a hose big time. Those were the only times I have blown hoses, except for once when a log rolled over the top of the bucket and pinched a hose causing a leak. So, to avoid blowing another hose I guess I will give up that practice. The good news is that it did cause me to clean up my typically dirty - dusty tractor though - after hydraulic oil shot all over it - even my wife noticed it was clean.

One key to back dragging is to put the control valve into "float mode". If you back drag without doing that, you will either break a hose or bend a cylinder eventually. For the few that don't understand what I mean, just ask and I will take the time to explain it. I also still recommend not back dragging at too severe of an angle. You want the bucket to float over things. Like that rock the OP tried to pop out. I have used back dragging for decades to spread gravel and dirt and make things smooth and I have never broken anything.

Nice video here - one of the uses of back dragging!

Hacksaw ,follow with 6 point socket. Hose is shot anyways.

Now that guy ain't using "float".

Nope.. And while it was loose dirt, and not likely to cause any damage, it was not the most efficient way to do it. Why not just drive over to the other side and push the trench in by keeping the bucket level to the ground and push. Do not empty the bucket between passes. Just let the bucket fill, and keep pushing while working way down the trench. With a hydro tractor like that, I could have filled that trench twice as fast as he did by backdragging. Just my two cents. YMMV

Agree. Also, I have used a box blade or grader blade to push and level dirt for projects like that. Also, I notice that the cylinders are attached to the bucket at different points - i.e., higher on that bucket than on my loader and bucket. I wonder if that affects the back dragging forces on the FEL as tcreely has suggested might be the case.

And how about backfilling a water line and cables with rock? No sand, no keeping the pipes in the corners of the ditch? Not good practice in my book.
