Maintenance

Figure 45

1.Sharpen at original angle

2.Check the balance of the blade by putting it on a blade balancer (Figure 46). If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Figure 46). Repeat this procedure until the blade is balanced.

Leveling the Mower Deck

Check to ensure the mower deck is level any time you install the mower or when you see an uneven cut on your lawn.

The mower deck must be checked for bent blades prior to leveling; any bent blades must be removed and replaced. Refer to the Checking for Bent Blades procedure before continuing.

The mower deck must be leveled side-to-side first then the front to rear slope can be adjusted.

Requirements:

The machine must be on a level surface.

All four tire must be properly inflated. Refer to Checking the Tire Pressure in the Drive System Maintenance section.

Installing the Blades

1.Install the blade onto the spindle shaft (Figure 44).

Important: The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting.

2.Hold the blade end using a rag or thickly-padded glove (or place a wrench on the top sheave nut). Apply lubricant to the threads of the blade bolt as needed to prevent seizing. Copper based anti-seize is preferable. Grease is an acceptable substitute. Install the washer and blade bolt and washer assembly.

3.Torque the blade bolt to 35-65 ft-lb (47-88 N-m).

WARNING

Incorrect installation of the blade or components used to retain the blade cause the blade to come loose and could seriously injure or kill you or bystanders.

Always install the original Exmark blades, washers and blade bolts as shown.

Side-to-Side Leveling

1.Park the machine on a level surface and disengage the blade control switch.

2.Move the motion control levers outward to the park position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3.Set the height-of-cut lever to middle position.

4.Carefully rotate the blades so that they are all side to side (Figure 47 and Figure 48).
