On threads of Blade Bolts See Check Mower Blades section.

Dielectric Grease

Dielectric grease is used on all blade type electrical connections to prevent corrosion and loss of contact.

Adjustments

Note: Disengage PTO, shut off engine, wait for all moving parts to stop, engage parking brake, and remove key before servicing, cleaning, or making any adjustments to the unit.

Deck Leveling

1.Position mower on a flat surface.

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

3.Check tire pressure in drive tires. Proper inflation pressure for tires is 10 psi (69 kPa). Adjust if necessary.

4.Set anti-scalp rollers to top holes or remove them completely for this adjustment.

5.Raise the deck to the 5 inch (12.7 cm) height position (also transport position) and take all force off of the two large deck lift springs by loosening the nuts at the front of each spring (Figure 15).

6.Lower the deck to the 1 inch (2.54 cm) height position. Force the left rear deck support arm downward about 1/4 inch (6.4 mm) to get the deck to rest at the 1 inch height position. Place locking pliers between the rear swivel and spring stop to hold the deck in this position (Figure 15).

7.Place a 3/4 inch (19 mm) thick block of wood under each of the two rear anti- scalp roller brackets and place one under one of the front center anti-scalp roller brackets.

8.Loosen the two top chain bolts in slots in the rear deck lift arms. Loosen jam nuts and back off the socket head adjusting screws on the bottom of the arms until the chains are just loose. Turn the socket head adjusting screws in until slack is taken out of each chain. Tighten the jam nuts. Tighten the chain bolts in the deck lift arms making sure they don’t move while tightening.

9.Loosen the four nuts which secure the front swivels (two per side) until the front chains are loose and front of deck is supported by the 3/4 inch (19 mm) block. Do Not loosen the front chain hardware.

10.On left side, adjust front swivel using the locking nut behind the swivel until the front chain is tight and all slack is removed from linkage. Do Not lift front of deck off 3/4 inch (19 mm) block. Secure
