Grasshopper Hydro Pump Problem

[CajunCub]

The manifold is a bank of hydroic controls...as a mechanic, I worked on alot of back hoes & that is what the line of control levers are called, I just called it that out of habbit. So, the valve is what I was talking about.
If you turned the pump, and fluid came out....look to another problem like the fluid motor it's turning or the cylinder that won't work, ect. Maybe the pump is ok....but yes, you could take it and have it rebuilt locally.

Thanks! Your thoughts gave me another idea. Since the drive belt only turns the pump in one direction, I'm going to loosen it and try turning the pump it in the opposite direction to see what that does.

If there is an obstruction, maybe that will dislodge it.

Took the bypass plug completely out. Started the engine and a little fluid came out then stopped. I'm thinking obstruction or dirt somewhere.

What do you think?

Check the tank....maybe some kind of blockage in it.

Took the pump completely off and apart AGAIN!

Cleaned it, blew all holes out with air compressor, re-installed and YIPEE! I was mowing in the rain! No problem for the HOPPER!:thumbsup:
