[Farmall] Sector Gears

[Robinson]

    The last Farmall M sector gear we bought came from TSC Stores quite 
some years ago. It was a full circle replacement made that way so that 
when it became worn it could be rotated 1/2 turn and the other side 
used. You might try contacting them to see if they still have access 
even though they don't keep them in the store.
    The gear should be the same for the M up to and including the 450. I 
don't know if the same gear was used on anything else like maybe the 560 
or not.
