2.Front height-of-cut plate mounting bolt

3.Rear height-of-cut plate mounting bolt

15.To adjust the single point system, first loosen the front and rear height-of-cut plate mounting bolts.

16.If the deck is too low, tighten the single point adjustment bolt by rotating it clockwise. If the deck is too high, loosen the single point adjustment bolt by rotating it counterclockwise.

Note: Loosen or tighten the single point adjustment bolt enough to move the height-of-cut plate mounting bolts at least 1/3 the length of the available travel in their slots. This will regain some up and down adjustment on each of the four deck links.

17.Re-tighten front and rear height-of-cut plate mounting bolts.

Important: Torque the front and rear height-of-cut plate mounting bolts to 27-33 ft-lb (37-45 N-m).

18.Repeat steps 9 through 13.

Deck Removal

Before servicing or removing the deck, the spring loaded deck arms must be locked out.

WARNING

Deck lift arm assemblies have stored energy. Removing the deck with out releasing the stored energy can cause serious injury or death.

Do Not attempt to disassemble the deck from the front frame without locking out the stored energy.

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2.Remove the height adjustment pin and lower the deck to the ground.

3.Place the height adjustment pin in the 3 inch (7.6 cm) cutting height location. This locks the deck lift arms in the lowest position when the deck is removed.

4.Remove the floorpan and belt shields.

5.Insert 1/2 inch socket driver into the square hole on the idler bracket and carefully rotate the deck idler counterclockwise to remove the belt.

6.Remove and retain the hardware on both sides of the deck as shown in Figure 29.
