5. Rotate the marked end of the blade to the 3 and 9 o’clock positions (Figure 121) and measure the heights. 6. Compare the 12 o’clock measured height to the height-of-cut setting. It should be within 0.7 mm (0.030 inch). The 3 and 9 o’clock heights should be 1.6 to 6.0 mm (0.060 to 0.240 inch) higher than the 12 o’clock setting and within 2.2 mm (0.090 inch) of each other. Note: If the 3 or 9 o’clock side is 1.6 to 6.0 mm (0.060 to 0.
Inspecting and Sharpening the Mower Blade(s) Two areas must be considered when checking and servicing the mower blade—the sail and the cutting edge. Both cutting edges and the sail, which is the turned-up portion opposite of the cutting edge, contribute to a good quality of cut. The sail is important because it lifts the grass up straight, thereby producing an even cut. However, the sail gradually wears down during operation.
Storage Note: Remove the blades and sharpen them on a grinder. After sharpening the cutting edges, install the blade with the anti-scalp cup and blade bolt; refer to Removing and Installing the Cutting-Unit Blade(s) (page 78). Preparing for Seasonal Storage Traction Unit 1. Always shut off the engine, and remove the key. Wait for all movement to stop and allow the machine to cool. 2. Thoroughly clean the traction unit, mower decks, and the engine. 3.
9. Seal the air-cleaner inlet and the exhaust outlet with weatherproof tape. 10. Check the anti-freeze protection and add a 50/50 solution of water and ethylene glycol anti-freeze as needed for the expected minimum temperature in your area. Mower Deck If the mower decks are separated from the traction unit for any length of time, install a spindle plug in the top of the spindles to protect the spindles from dust and water. g036712 Figure 126 1.
