   A - Draft Link Nut (4 used)

   If the front-to-rear difference is within specification, tighten draft link nuts (A) and go to step 12.

10. If the front-to-rear difference is greater than 13 mm (0.50 in), loosen draft link nuts (A).

    1. To raise the front of the deck, shorten the draft link.

    2. To lower the front of the deck, lengthen the draft link.

    3. Return to step 4 to measure the front-to-rear level.

11. If the front-to-rear difference is less than 13 mm (0.50 in) but greater that 3 mm (0.125 in), tighten the draft link nuts (A).

    4. Shorten both turnbuckle assemblies an equal number of turns to raise the rear of the deck.

    5. Lengthen both turnbuckle assemblies an equal number of turns to lower the rear of the deck.

    6. When the adjustment is complete, install the retaining pins.

    7. Return to step 4 to measure the front-to-rear level.

12. Connect the negative battery cable.

13. Lower the deck to the ground, stop the engine, and remove the key.

    Draft Link (—MY19) Shown, MY20— is Similar

    A - Draft Link Nut (4 used)

    B - Draft Link Gap

    Measure the draft link gap (B) and compare to specifications.

    Item	Measurement	Specification
    Draft Link Gap (B)	Distance	3 mm 0.125 in

---




15. If the draft link gap (B) is not to specification, loosen the draft link nuts (A).

    1. To decrease the draft link gap, shorten the draft link.

    2. To increase the draft link gap, lengthen the draft link.

    3. Return to step 4 to measure the front-to-rear level.

16. If the draft link gap (B) is to specification, the front-to-rear leveling procedure is complete.
