Loader activating while operating backhoe

upsbeerman · Jul 24, 2023

First time posting here. I have a Branson 2515h and my front end loader rises while I am lowering my stabilizer on my backhoe. I have very little know how when it comes to the hydraulics so any help would be greatly appreciated. Thanks in advance

A loader valve that is not centered can allow pressure in one system to affect another. It is also possible for the inter system leak to allow the loader to move when the stabilizer becomes under load from hoe activity. describe the time window overwhich this has happened. if all worked well until today, the cause was today. if it has increased over time, there may be wear factors on valve components.

Just give us a history on it. They do not charge be the word so use as many
as needed.

Hello beerman welcome to YT! Did everything work as
it is at one time. Make recent changes? Does it do this
if the the loader is off the ground? What happens when
you dead end the stick and continue to hold the lever
bypassing the relief? The stabilizer cylinder may have
restrictors in the lines to reduce their deployment
speed. This may slightly open the relief valve during
their operationi. Just trying to figure out if the loader
cylinder valve is being pushed open when a higher
pressure is present in the system.

Is the hydraulic system electric over hydraulic?

Hey Jim, thanks for the response. I will check it tomorrow and get back to you. It is possible that it wasn t centered. It is a recent issue, just started doing this last time I used it. Thanks

Thank you for responding, so the other day I m out moving boulders for my fire pit with the backhoe so I can get straps and chains around it. While setting my stabilizers, I realized that my loader was raising all the way up. Now my stabilizer was actually already set. It was when I was putting more pressure on it for a little more stability that the loader started going up. So that is pretty much my issue. Thanks for the feedback and I hope this gave you more to go on.

Hey rusty, thanks for the response. I m pretty sure it is electric hydraulic since there is a hydraulic pump that only engages with key on. Am I right in thinking this?

It turned out that the loader wasn t actually centered at the time I haven t had any issues with it since.
Thanks for the help.
