700 Series Lawn Tractor
6. Measure the length of the adjustment link to see if it
is at the factory specification, 7-1/2".
See Figure 5.18.
NOTE: Lengthening the adjustable rod to factory
specifications (or longer) should eliminate
the creep.
7. Loosen the link jam nut securing the ball joint to the
adjustable rod using a 9/16" wrench.
8. Remove and discard the cotter pin that holds the
plain end of the adjustment rod to the cobra head
arm on the pedal shaft.
9. Remove the rod from the cobra head arm and move
the arm back towards the rear of the tractor. This
will give you room to rotate the rod on the ball joint.
10. Secure the drive control pedal in its most rearward position. Use a helper or bungie cord if necessary.
11. Thread the rod out of the ball joint end to lengthen it.
12. Adjust the rod length so that the cobra head arm fits easily through the hole in the adjustment rod without mov-
ing the cobra arm.
NOTE: The drive belt should appear loose at this time.
13. Fasten the adjustment rod to the cobra arm with a new cotter pin.
14. Tighten the jam nut.
15. Test-run the tractor to confirm that the drive and brake systems work correctly before reinstalling the mowing
deck. If the tractor still creeps, you will need to lengthen the adjustment rod again and retest.
16. Test and repeat until there is no tractor creep.
17. Install the cutting deck and confirm that all of the safety features work properly.
