I bought my BH75 last year and it worked great at first. But I feel like my backhoe is not as powerful as it was at the beginning. It seems that I get jammed more often. When time comes to rip off a stump the bucket seems to jam easily. The leak down is quite fast. I have to use the boom lock pin if I don't use the backhoe within the hour because the bucket gets in the way in no time.
I don't know what to do. I talked with my dealer and he told me that I complain for nothing, it's normal. I don't understand because my former BX23 was incredible on that, virtually no leak down at all (nothing for the loader, a tiny little bit for the backhoe). My backhoe was still up and almost in fully raised position overnight. Now things are very different with my B3030 and BH75. My FEL is great though, no leak down whatsoever, but the BH75 is on the ground in no time. The stabilizers too drop a lot.
One guy told me once to be attentive if I can hear an abnormal "hissing sound" when using the backhoe. I'm not an expert, all I can do is compare my BH75 with the one on my former BX23. It seems, to me, when I compare that my control valve does a lot of "hissing sounds". Much more than the one on a BX23 and probably more now than it was when it was brand new.
So, what do you think about that guys? Does it seem to be a problem with the control valve (probably) are the cylinders? As I said, I'm not an expert but I understand the mechanical of a valve and a cylinder. I know that it could be an O-ring or a seal (or more than one) in the control valve leaking a bit when the spool is moving thus losing pressure (not all of it but enough to prevent maximum pressure thus maximum power). But your opinions are important to me guys. Thanks
There's a positive point here though, I cannot bend my cylinders because I don't have the hydraulic power to do it.
If you have any similar experiences as mine don't hesitate to drop a reply. I'm sure I'm not the only one in a situation like that.
