DIFFERENTIAL LOCK (Fig. R5)
The lock needs to be adjusted if it does not function per-
fectly, or if, for some reason, it has been necessary to
disassemble it.
With the adjustment make sure the cylinder does not
push the engagement fork too far and that the disen-

turns on correctly in regard to the lock operation.
‡ Raise the table (or just the crop elevator) to its top
position and make sure it will stay up. (Service sup-
port and trestle beneath the table.) Make sure that
the table pressure remains in the system.
‡ Raise one of the front wheels off the ground and
support it with a trestle. Set blocks on both sides of
the other wheel.
‡ Engage the lock and gear. (The ignition key shall be
in position I with the engine not running.)
‡ Rotate the raised front wheel by hand until the lock
gets engaged and the wheel stops.
‡ Slacken nuts A and C. Turn nut A until it touches part B. Then turn it two rounds to slacken.
‡ Tighten nuts A against part B.
‡ Slacken screws D and move the light switch fastened with them as far left as it easily moves. (The light switch
goes to the bottom.) Tighten screws D.
‡ Disengage the lock and gear and lower the wheel.
