no it wasn't me,was sold when I called,I live in north al
3ph works off same pump as loader/power steering,if loader/steering works pump is good,you may have bad seal on lift piston which is preaty common
I had a long with hoe that had those bars to hold/lock it in place
I would get that hoe off and go from there,good luck

little late to the party but in last pic the lift arm is way over extended (raised way up beyond where it should EVER be.) What happens is the piston pops out of the bore and damages the seal when this happens most times. kind of common problem on this series of tractor. the lift arms also do not "LOWER" under pressure so with nothing ON the lift arms they will NOT lower (have to have weight pulling them down.) they use pressure UP only.

Thanks for your help. I was pretty sure that the seal was the problem based on so many of the other threads. I am in the process of trying to take the backhoe off, but I ordered a new piston/hoses for one of the stabilizers and that is taking forever to come in. Not to mention having to purchase the adapters for 18mm fittings

The only other thing that wasn't mentioned is that it looks like you have draft control. Of course make sure you are moving the correct lever. It looks like yours are labeled. Also make sure the draft control is set to low/no sensitivity, probably all the way forward.

On my Kama it doesn't like to go down with no load. It actually likes to drift all the way up.
