90 dollars an hour shop fee, and they still didn't find the problem.

    While not on the platform, the levers lock into the neutral position to where you can't move them at all.

    If you move the auxiliary lever, nothing happens.

    If you have the auxiliary on, and get off the platform and back on, nothing works until the auxiliary is put back into the neutral position.

    Who ever came up with the idea of putting a clutch in the middle the tractor and having to split it to change it, should of been slapped.

    It's the same as a truck, it's just that the frame structure of a tractor is integral to the motor, trans, clutch, and rear end. Makes it solid.

    A truck relies on the frame.

    So really there is no other way around it.

    Are you using the right kind of hydo fluid? Maybe as it heaats it its becoming too thin and thusly the loss of umph.

    I was thinking that too, but his loss would be gradual then.

    Well Should tell you the 7740 doesn't really have a normal clutch

    There are 3 clutches packs everything is electric ran
    Low side clutch for all 8 gears High clutch 1-4 and High clutch 5-8
    If all 3 goes out its 3k to replace them

    I wonder what the big tractors use. So is that how the old 3 ranges worked? My dad had a 4430 with a 10(if I remember right)speed power shift. He also had a 4630 front axel, and did not have a raised air cleaner like 90 percent of them did. It was a pretty rare tractor and the surrounding farmers were always borrowing it.
