    Default B7100/7001 Diff lock

    Hi all,
    the diff lock on my kubota B7001 (the B7100 is the same) is operated by a pedal which rotates a shaft going in to the transmission case. This shaft seems to be completely seized yet the condition of the tractor is excellent. Can anyone shed any light before I take the thing apart? I have a manual but it's not clear enough to see what's what. thanks.

    Find where the shaft goes into the differential case. Soak it with PB Blaster or some other good penetrating oil. Let it soak then work petal back and forth. Be patient, in a situation like this time is your friend. Repeat the soaking and wiggling. My guess it it will free up and work properly.
