I have a Satoh 650 and I have a unique problem that is occurring, and not sure the answer. I've read many many threads, but cannot find a reasonable answer/assistance with my particular issue.
First, my tractor has rear draw bar and a front loader. It has the separate control units for each (rear draw bar is standard, like is on all models). The valve control assembly for the loader may or may not be orginal. Not sure.
The issue is this: When i raise the draw bar (demand fluid), my levers on the loader valve control snap forward, dump and lower the loader. This continues to happen until the bar is raised to the required height. It seems to me (backyard mechanic) that when the bar is raised and demands fluid, it is pulling from the loader control valve assembley, causing the loader to dump and lower. Here are some other facts to help with diagnose the issue:
* Only occurs when bar is raised.
* Loader works fine when used independently.
* Lowering bar has no effect on loader or control valve assembly.
* Fluid levels are good.
* Filter is clean.
* Speed on bar and loader (up and down) are good (good pressure).
Is there a check valve or something in place to prevent this? Can you help pinpoint the issue any further?
Thanks in advance.
