Mini Z - right side has no power?

[pajohn]

Just happened all of a sudden. The right side will barely move, left side is fine. I checked all the linkage and it looks fine. Bad hydrolic motor or whatever it's called on that side? Anything else to check?

check the hydro. fluid, Belt tension and make sure the pump bypass valve is closed.

Also check the bracket that the linkage is attached to at the pump, some manufactures use a set screw to hold that bracket onto the pumps input shaft and they back off and creat play right at the pump.
Fixed many a weak drive system with only an allen wrench:)

I got it. There was a nut on the pump that was loose (bypass valve?) I just snugged it up and all is fine. Thanks guys.
