    It may say imported from Germany somewhere in your paperwork, however I think you'll likely find it was actually made in Turkey. But it's still too short.

    But it's still a gimmick for a tractor as new as yours. The DPCV system only benefits owners who already have a hydraulic leakdown problem. You paid for a feature you don't need.

    Disconnect the QDs as was suggested and you will find out if it is the cylinder or the spool valve.

    If it is the cylinder, let me know, if it was purchased from me I will take care of it, but I'm guessing that it is the spool valve.

    Is the problem while you are in transport or while you are cutting?

    Well, they seem to make two models and mine is the longer one so obviously all is well. Top link will extend to 31" eye to eye which is longer than the manual one. The DPCV is the only way they sell it and it was under $200.00 (plus the hoses) so I think I got a good deal.
    DF 254G2 with cab and Townsunny fel-250 loader with Prince Hydraulics joystick. BE 72" finishing mower and 72" snowblower with hydraulic rotation and deflection. Hydraulic top link, 72" Townsunny box blade. Adaptor to mount 3pt attachments on front end loader in place of the bucket. Woodmax 8" hydraulic feed wood chipper (makes the poor DF work). Pallet forks that mount front or rear.

    Cleat,


    Nice setup there. I just ordered mine from Brian at Fit Rite Hydraulics and am anxious to get it. I have a heavy duty bush hog that I would like to be able to raise for cleaning and inspection like yours. I also want to get a post hole digger and I'm guessing the top link would be nice for adding some downward pressure. Enjoy the new toy!

    Nope. HTLs don't work that way. To lift an implement, the tractor pumps hydraulic fluid into the cylinder. But to drop one, it's nothing more than gravity that pushes that fluid back into the sump.

    Will do. Thanks for the information. It is doing it while both mowing and during transport in the raised position.

    I misunderstood your post and thought you were talking about HTLs. But you are actually talking about the lift cylinder if I understand correctly.
    Which is bigger?: a) $100 per month since the Big Bang or b) the US National Debt.

    Greg is correct. If you extend the top link it will only raise the lift arms, because they float, unless you have them mechanically locked. like the backhoe setup.

    The PHD mounts where the top link mounts. To get a hydraulic to work properly with the PHD, you have to get or make the proper mounts so that you get down pressure at all. You need to change the double acting cylinder into a single acting cylinder along with a pressure regulater, bypass hose etc.

    If you do not do all of these things, you will end up breaking SOMETHING.

    Best thing to do if you want-need down pressure on your PHD, get a down pressure unit for that PHD.

    I'm confused, how or why does it make any difference while you are mowing? There are many people that use chain for the top link when mowing(not recommended by the way) or put the top link in float mode so that the mower follows the ground. The lower 3pt arms and tail wheel support the mower. The top link should not come into play at all.

    Are you still running this on the Massey? Let me know how the test turns out.
