Not so exclusive club: dragging by hydraulic hoses

So we are all familiar with the not so exclusive club of the overhead door smashes with the ROPS...

how many of you have joined the elite club of testing the tensile or pulling strength of your hydraulic hoses?
I first did this about 3 years ago when detaching my artillian grapple - forgot to unhook hydraulic lines and dragged it a couple feet backward by its lines... bent a couple but ok

the other night my dump wagon somehow managed to detach (the bxpanded hitch wiggled
Loose
From the draw bar)
And I was greeted by the wagon trying to walk itself down the hill, hydraulic lines taut and the valve coupler spewing hydraulic fluid

thankfully a couple throws of the wrench and crisis averted...

but man oh man !

I did once...I had made FEL snowplow when I had my old 4110, unhooked it in the driveway once and backed up at full speed...only to realize I forgot to unhook the hoses. Nothing broke and no one saw it happen, so win-win.

If no one saw it, it did not happen!!!!

Shortly after getting a new tower air blast I ran it into the garage door opening. I was extremely cognizant of this but a contractor had a trailer parked very close to the garage and the bucket of the tractor was really CLOSE to the trailer and I was focused looking forward rather than rearward. I now have marks on the 3 point control where the lift arms need to be.

Didn't do much, bent the plenum a little. I redid 3 rivets.

This was a test with just water in it.

speaking of spewing oil....
It must have been about 1979 or 80 I was opening up a hay field with a Deere Hydroswing mower conditioner like this:
751225


The hitch was a removable steel bar bolted to the tractor hitch with a single 3pt pin pointing up. The ball in the tongue went over the hitch and was locked in place with the lynch pin. There are 3 sets of hydraulic lines, 1) L/R turn, header 2) up/down, and 3) the large hose in the picture below is the return line for the hydraulic reservoir (most of the tongue) and the pressure line coming from the pump. The pump was like most PTO mounted pumps where it had a steel bar that rested on the drawbar to keep it from spinning. Dad was helping me get everything connected, and in the process, neither one of us put the lynch pin in the hitch.
751226


It's common, especially when opening a field up, to make turns and corners where the tractor tire will rub on the hitch (top photo shows the rub marks), on my last tight corner, the tractor wheel caught the tongue, and it popped up off the pin. I don't recall how far I made it before hitting the brakes, but the first thing I saw was a fountain of oil coming out of the hitch in a really nice arc, glistening in the sun.

I wrapped a couple of grease rags, around a hitch pin and wedged it into the suction line and was able to significantly decrease the oil flow, but not before loosing a few gallons. It was not under pressure AND the PTO was off, but that oil was HOT, not sure why I was not burned, lucky I guess.

Who knows, there might still be nothing growing in that hay field in that spot. So yes I feel you pain....

Remembering to disconnect my hoses from the grapple before backing away was the hardest part of it. I nearly jerked it off the blocks 3 or 4 times.

The other thing was learning to move the loader control to neutral before letting go of the diverter button. That became second nature pretty quick.

had a 16' wheel disc i was pulling somehow lose the pin while pulling.........the hoses just popped out of the tractor scvs........wasnt a big issue.......it was a 80s era tractor i wonder if it had breakaway couplers? ......i am not sure how you know if you have break away couplers?

Not sure either, but perhaps this explains why our White 2-85 will just pop them should you have a moment when unhooking, though they do stretch a ways first.

HA! I made two decals with red reflective sign vinyl and put one on each side of the grapple. Next time I disconnect it I just about jerked it off the blocks. I scraped the decals off because they made me look stupid.

I finally got the transition from bucket to grapple and back down pat.

I watched a guy who'd been driving dump truck for YEARS, pull up near me, and stop.
He went through the motions of disconnecting his trailer, and got back in the truck.
He put the truck in gear, and pulled away like he had somewhere to be.
When he did, he flat out NEUTERED the trailer, by not disconnecting the hydraulics.
The hydraulic line stretched out like a rubberband, but did not disconnect.
It pulled apart, deep down inside the trailer tongue, and was pissing it's body fluids from the truck and trailer EVERYWHERE.
I was waving and yelling as he was moving away, trying to get him to stop.
By the time (I finally got his attention about 100yards away) he stopped, both the truck and trailer (hydraulics) were bled out.
That was about 20 years ago. To this day, he still gets reminded of that day, by a LOT of people, of the castration day. LOLOL

Done that multiple times with my grapple used to hit my garage door until I got my shop built, 10 foot doors solved that problem! I have also broken several fitting on the hoses that connect to the grapple. Sometimes a branch or something will get in there and snap it off. Normally it's a 90 degree fitting. I am kind of glad the cheap Chinese fittings are "breakaway" as it saves the hose and other more expensive parts....just always happens at the wrong time. I am getting smarter though, I now have a spare fitting or two in the hopes I minimize down time. :cool:

I've never done the hydraulic hose thingy, but we won't talk about gooseneck trailer disconnecting.

Never done the hydraulic hose pull either, or should I say Yet. Thanks to the OP this is out there looming in the shadows just waiting, kinda like the boogey man.

However I can tell you that a 7 pin electrical connection is not a good tow point.

I'll confess. First time I unmounted the FEL after getting the 3rd SCV and grapple I forgot to unplug the 3rd SCV.

In the "It's not my fault" category, that %^&* MMM hydraulic lift fitting would never stay tucked when I had the FEL mounted and one time while clearing some brush it hooked a wild grape vine. Thoroughly impressed with the hose and fittings as it actually stopped the tractor when I was trying to back away from the brush pile. Thankfully it pulled tight before I had any momentum built up.

I’m not a member of this club - yet - and I sure hope I don’t ever join. I’ve made enough other mistakes. But I appreciate this thread as a great reminder. So I’m thinking about how to prevent inadvertent membership....

For some things, like hooking up a trailer, I have a mental checklist that I always run through. This includes doing the same steps in the same order every time, and then a double-check in the same order.

Another possibility might be some kind of “warning flag” on the grapple or other highly-visible spot that will catch my attention. (Not to be confused with all those useless warning labels that come plastered everywhere on new equipment that I carefully peel off as soon as I get the machine home.)

Anyway, this thread was a great reminder to me.
