On any mower I use the ramp of mu tilting trailer
Engine off brake released if the hydros are good it will sit there and not move
If the hydros are stuffed it will race away like Mulga Bill's bicycle

The dump valve is indicated by the arrow. It will be on the other side of one unit as there is a LH and RH unit. The pin is either pushed in or pulled out opposite of the current position. When in bypass mode it keeps the check valves open.

So check your owners manual for the one used by Grasshopper.

Thanks! Although my setup is different than the picture, (it has one tank for both pumps).
