Removing the Blades Note: If the blade stays in a horizontal position, the blade is balanced and can be used. Replace the blades if they hit a solid object, or if the blade is out of balance or bent. 1. Place a wrench on the flat of the spindle shaft or hold the blade end using a rag or thickly padded glove. 2. Remove the blade bolt, bushing, and blade from the spindle shaft (Figure 107). Note: If the blade is not balanced, file some metal off the end of the sail area only (Figure 108).

Fine-tune the adjustment nut on the front deck-lift assembly by turning it (Figure 114). Note: To increase the height, turn the adjustment nut clockwise; to decrease the height, turn the nut counterclockwise.
14. Torque the 2 bolts to 37 to 45 N∙m (27 to 33 ft-lb). 15. On both sides of the deck, measure from the level surface to the back tip of the blade (postion B) as shown in Figure 113. Note: The measurement should read 8.3 cm (3-1/4 inches) 16. Fine tune the screw adjuster by turning it to get 8.3 mm (3-1/4 inches) height (Figure 114). To increase the height, turn the adjustment nut clockwise; to decrease, turn counterclockwise. 17. Measure until all 4 sides are the correct height. 18.
8. Raise the deck struts and secure them in the raised position. 9. Slide the deck out to the right side of the machine. 6. Important: The grass deflector must be able to rotate. Lift the deflector up to the full open position and ensure that it rotates into the full down position. Replacing the Grass Deflector WARNING An uncovered discharge opening could allow the machine to throw objects toward you or bystanders, resulting in serious injury. Also, contact with the blade could occur.
Cleaning Storage Cleaning under the Mower Deck Storage Safety • Shut off the engine, remove the key, wait for all moving parts to stop, and allow the machine to cool before storing it. Service Interval: Before each use or daily 1. • Do not store the machine or fuel near flames or Park the machine on a level surface, disengage the blade-control switch (PTO), and engage the parking brake. 2.
13. Prepare the machine for storage when non-use occurs over 30 days. Prepare the machine for storage as follows: A. Add a petroleum-based stabilizer/conditioner to fuel in the tank. Follow mixing instructions from the stabilizer manufacturer. Do not use an alcohol-based stabilizer (ethanol or methanol). Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel and used at all times. B. Run the engine to distribute conditioned fuel through the fuel system for 5 minutes. C.
