5. CAUTION: Rotating blades are dangerous. Before adjusting or servicing mower:

   • To prevent engine from starting accidentally, disconnect the negative (-) battery cable.
   • Always wear gloves when handling mower blades or working near blades.
   
   

   Stop the engine, remove the key, and hang a "DO NOT OPERATE" tag in the operator station.

6. Wait for the engine and all moving parts to stop before leaving the operator seat.

7. Disconnect the negative (-) battery cable.

8. NOTE: Adjust the front blade of the mower lower than the rear blade of the mower.

   Do not allow the mower wheels to contact the ground during leveling.

   A - Left Blade

   B - Right Blade

   Turn the left blade (A) as shown. Hold the drive belt and turn the right blade (B) as shown. Take blade tip-to-surface measurement on both ends of each blade and compare to specification:

   Item	Measurement	Specification
   Blade Tip Front-to-Rear (front is the lower end)	Height Difference	3 mm 0.125 in.

   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 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).

       A - Retaining Pins

       B - Turnbuckles

       Connect the negative battery cable.

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

    3. Remove the retaining pins (A) and pivot pin securing both turnbuckles (B) to the lift arms.

    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 previous steps 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.

    A - Front Draft Link Nuts

    B - Pivot Pin

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

    Item	Measurement	Specification
    Draft Link Gap	Distance	3 mm 0.125 in.

    • Uneven ground requires a larger gap, while level ground requires a smaller gap. Too much gap effects front to rear deck leveling. Too little gap causes lock to function improperly.

15. If the draft link gap 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 previous steps to measure the front-to-rear level.

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