John Deere 9520T

    Here is a little progress on the 9020T tractor I am working on.


    Belttension is designed with bearings in the 'forks' instead of placing them in the wheels.

    The walking beam is now done. On the pictures you will see how I made the attachments to the frames.

    The issue is that, by moving the two frames up and down from center/zero the distance is getting bigger and when the beam is attached, it forces the frames to move inward and therefore no longer parallel.

    I came up with the idea, that if I let it 'rotate' over a square piece, it would spread the frames when the beam travels up and down. Also the beam will be able to travel backward (about 1.5mm) on the mid axle. As this distance also get's shorter.

    Next up is the gearbox.

    Mainframe is milled out to make room for transmission and rearaxles.



    Left and right side of the undercarriage is almost done.





    Hello Anders,

    simply awsome!!! Incredible work, as usual, when you start a project! How is the rubbersurface on the wheels made? Is it a Shrinktube?

    So here is the latest activity from my workbench.

    The undercarriage and transmission of the 9520T tractor is finally taking shape.
    Trackframes has been done for a while, just some small touch ups here.

    Transmission though is now nearly complete and fits perfectly inside the mainframe.

    As you will see on the back, I have drilled the holes for all the bolts to fit either a 3pt hitch or a wide swing bar. I am not sure what to make yet. I better start with the swing bar as I want to get the rig pulling as soon as possible.

    Not much to say, as the pics will tell you the most
