MAINTENANCE Cutting Blades For the best mowing results, it is important that blades are well sharpened and not damaged. Replace blades that have been bent or cracked when hitting obstacles. Let the service workshop decide whether a blade with large nicks can be repaired/ground or must be replaced. Balance the blades after sharpening. Check the blade mounts. CAUTION! Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling. The sharpening of blades should be carried out by an authorized service workshop. 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. Seat the blade's opening firmly onto the cutter housing. 4. Tighten blade bolt securely. 5. Torque blade bolt to 45-60 ft/lbs (60-81 Nm). V-belts Check every 100 hours of operation. Check for severe cracking and large nicks. NOTE: The belt will show some small cracks in normal operation. The belts are not adjustable. Replace belts if they begin to slip from wear. Deck Belt Removal 1. Park on a level surface. Apply park brake. 2. Lower the deck into the lowest cutting position. 3. Remove bolts from belt shields and remove shields. 4. Remove any dirt or grass that may have accumulated around the cutter housings and entire deck surface. 5. Loosen the nut securing the belt guide. Pull the belt guide up out of the idler arm. 6. Push inward on the idler arm to release the tension on the belt. IMPORTANT INFORMATION Special blade bolt is heat treated. Replace with a Husqvarna bolt if required. Do not use lower grade hardware than specified. 7. Carefully lift the belt over the top of the cutter housing pulleys and remove belt from the deck. Deck Belt Installation NOTE: For ease in installing the deck belt, refer to the routing decal on the top of the deck. 1. Wrap the deck belt around the electric clutch pulley located on the engine shaft. 2. Route the belt forward and up onto the deck. 3. Place belt around spring loaded idler pulley. 4. Wrap the belt around the stationary idler pulley and around the mandrel housings. 5. Push inward on the idler arm and carefully route belt over stationary idler pulley. Once the belt is properly routed, slowly release the idler arm to tension belt. 6. Double check belt routing to make sure it matches the decal affixed to the deck, and the belt does not have any twist. Correct if needed. 7. Set the loosened belt guide into the idler arm hole and tighten the pulley bolt. Replace belt shields on both mandrel housings and secure with fasteners. 24
