</font><font color="blue" class="small">( Should I have gone with the Rhino backhoe instead of the Kioti? I like the Kioti because it's a subframe mount type and seems to be built good. )</font>
Someone will be sure to correct me if I'm wrong, but that probably wouldn't make any difference.
The Kioti Backhoes used to be made by Rhino, and there isn't a lot of difference in the operation of the hydraulics between the two.
The problem is that you are using the remotes to power your backhoe instead of tapping of the main valve block where your loader is connected.
Now, I'm not sure, but I believe you get a little more power from this arrangement than using the remote valves.
Now, I may not be correct because maybe the tractor relief will still kick in before the backhoe relief would, causing the same problem.
I'm sure of one thing, Wallace is right. If you get a separate hydro pump powered by the PTO, you'll get better performance because then your only limitation is the backhoe's pressure relief, not the tractor's.
I'm not sure if that remote is a detent valve, keeping the hydro pressure constant, but it should be. But it's possible the wrong type of remote was installed. Not likely, but possible.
We need some hydraulic expertise here, and I SURE can't lay claim to that! John
