g,Day Bobby Carmon.
The hydraulics on the to 30 are not the same as the 165.
Although it is a Scotch yoke pump that is all they have in common,no hydraulic filter so dont waste time looking for it,for the hydraulics to work the pto should be engaged that is the transmissoin in neutral and the pto lever engaged ,the pto is driven via the hydraulic pump so if the pto is turning so is the pump!!.
The hydraulic control lever is simple to operate ,up or down and hold is SOMEWHERE in between,the hydraulics will stop working if you depress the clutch so if you need the pto to drive something you will have to move of and the pto will start to turn ,not a really good idea.
Happy Days .
