I'm hoping someone can help me diagnose a hydraulic problem. I just got a postdriver that I want to run on my B2710, and I'm completely ignorant about hydraulics.
The postdriver has a single control lever with three positions -- up, neutral, and down. Neutral is the position it stays in if untouched. Because of it's special use, the postdriver has a large diameter return tube that goes directly into the hyrdrauilic reservoir, rather than using a return line with a quck coupler.
Also my tractor is fitted with an extra hydraulic circuit, which was intended to be used for a hydraulic toplink and a cement mixer. It originates at the box at the base of the FEL controller lever. I returned the cement mixer and never got the hydraulic toplink, so I normally keep the two tubes that comprise this circuit connected together with their quick couplers. If the tubes are disconnected, the tractor bogs down.
If I separate the two tubes that comprise the extra circuit, and attach the input line to the postdriver, the tractor does not bog down, so I belive that hydaulic oil is flowing normally. If I push the postdiriver controller lever down -- meaning drop the driver --- the tractor bogs down, but the postdriver doesn't even wiggle. There is room for the postdriver to slide down a little on its tracks. Thereis a safety pin, but I removed it. If I push the lever up, nothing happens at all. In addition, when the postdriver is hooked up, moving the three-point lever has no effect at all. This in of itself witl be a problem if I can't fix it.
Finally, the person who installed the cement mixer told me to use the male end of the extra hydraulic circuit as the input to the postdriver. I believe he was mistaken, as the tractor bogs down in this configuration, regardless of the position of the lever.
Thanks in advance!
