Since the TRACTOR RR UNIT is not equipped with a
sensor, procedures 5 through 7 are not required when you
remove only the TRACTOR RR UNIT.
When you route the RTRPE sensor cable, make length
adjustments as necessary to meet the following conditions:
 Minimal or no tension on the cable when the
TRACTOR RL UNIT is moved to the extreme left.
 The cable must not interfere with the Tractor shaft
when the TRACTOR RL UNIT is moved to the
extreme right.
