    Default building a 3 point disc

    I am in the process of building a 3 pt, tube. disc frame is 4' x 4', I have the disc's 18" notched with 1' square hole, making a one row disc as opposed to a two row just to expose rocks before roto tilling. I see asc have axles and 4 bolt square bore bearings, short and long spacer for each side of bearing.
    questions:
    does anyone have close up pictures of a 3 point disc sealed bearing and gang ?
    7 1/2' space or 9" ?
    axle length to cover L4400 tires ?
    angle to set disc's at? (more aggressive being single row) ?

    would appreciate any suggestions thank you, Dennis

    On my Ford 54" tandem disc the spacing is 9". The short spacer would go between the bearing and the back of the disc blade, Long spacer goes between the bearing and the cutting side of the disc blade. Won't a single gang have a tendancy to push the rear of the tractor sideways? If you want to expose rocks a chisel plow of field cultivator will lift them out better than a disk and if the rocks are too large you can also break the disk blades.

    There is no difference in the gangs for a 3Pt mounted unit than a towed on of similar size.

    I built mine from an old JD drag disk. Made it as an "offset":
