    Anyone know how one could release the hydralic hoses out of the hydralic nozzles of this tractor? They are extremely difficult to release. I have to pull them with extreme force to get them out. I have tried powering down tractor and then releasing the pressure with the hydralic levers inside the tractor but with no success. Anyone have any advice?

    I have seen this before in other hydraulic equipment. I am assuming you are using Quick Release couplings to couple them toghether? Anyway I would suggest that you get a couple of "Screw on couplings" They simply screw on and you tighten with a spanner, getting them off is the same in reverse regardless of back pressure in the system. Try Torque hydraulics or Micro Hydraulics - both in Dublin they should have what you need.
    I think the back pressure problem could be related to leakage in the valve chest/section so screw on couplings are the cheapest option!

    hope this helps

    Screw ons are a paint in the arse as you loose all the fluid from the lines everytime you take them off.

    The quick fit couplings get tight over time and the collars in the female ones can get damaged. Check the balls in the female coupling are not siezed. If they are this is what will be leaving it very hard to disconnect.

    Flicking the levers forward and back to relive any back pressure is also a good idea. Also, push them forward before you try and pull the collar back

    If its just a normal quick release without the release collar then just push the hose towards the coupling and then pull it out in one quick action.
    Some JDs have a lever beside the fittings which you either push or pull to release the hose.

    Agreed, there shouldn't be a problem disconnecting if you're doing it properly. You have to push the hose towards the tractor and then pull it back. Also leave the spool lever in the tractor in the float position when disconnecting to relieve any pressure in the system
