MAINTENANCE

Cutting Blades

To attain the best mowing effect, it is important that the blades are well sharpened and not damaged.

Bent or cracked blades or blades with large nicks should be replaced.

IMPORTANT INFORMATION

The sharpening of blades should be carried out by an authorized service workshop.

Damaged blades should be replaced after hitting obstacles that result in a breakdown. A service workshop should decide whether the blade can be repaired/ground or must be replaced. Balance the blades after sharpening and check the blade mounts.

Blade replacement

1.Remove blade bolt by turning counter clockwise.

2.Install new or resharpened blade with stamped “GRASS SIDE” facing towards ground/grass (down) or “THIS SIDE UP” facing deck and cutter housing.

3.Install and tighten blade bolt securely.

4.Torque blade bolt to 90 ft/lbs (122 Nm).

IMPORTANT INFORMATION

The anti-scalp rollers must not be used for gauge wheels or the roller and deck may be damaged.

Anti-scalp Rollers

Anti-scalp rollers are properly adjusted when they are just slightly off of the ground when the deck is at the desired cutting height in the operating position. Anti- scalp rollers then keep the deck in the proper position to help prevent scalping in most terrain conditions.

IMPORTANT INFORMATION

Adjust anti-scalp rollers with the mower on a flat level surface.

The anti-scalp rollers can be set in three positions:

Upper position 1½ to 2½" (38 to 64 mm) grass

Middle position 2½" to 4" (64 to 102 mm) grass

Lower position 4" to 6" (102 to 128 mm) grass.

The rollers should be approximately ¼" (6.5 mm) from ground. Do not adjust the rollers to support the deck.

WARNING!

Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.

IMPORTANT INFORMATION

Special blade bolt is heat treated. Replace with a McCulloch bolt if required.

Do not use lower grade hardware than specified.
