Operation WARNING Using a high-lift blade with the mulching baffle could cause the blade to break, resulting in personal injury or death. Note: Determine the left and right sides of the machine from the normal operating position. Do not use the high-lift blade with the mulching baffle. CAUTION If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Atomic Blade This blade was designed to provide excellent leaf mulching.
Operating Tips Mow when the Grass is Dry and shreds grass, causes grass to turn brown at the edges. This impairs grass growth and increases susceptibility to diseases. Ensure that the blade is in good condition and that there is a full sail. Mow either in the late morning to avoid the dew, which causes grass clumping, or in late afternoon to avoid the damage that can be caused by direct sunlight on the sensitive, freshly mowed grass.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Every 50 hours Maintenance Procedure • Check the blade stopping time. • Grease the bearings CAUTION If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.

Wrap the Remove the lynch pin securing the deck-carrier frame to the lift-arm pivot pin (Figure 13). blades or wear gloves, and use caution when servicing the blades.
g011353 Figure 14 5. 6. Rotate the marked end of the blade to the 3 and 9 o’clock positions (Figure 14) and measure the heights. g031692 Figure 15 1. Height-of-cut bracket 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 (0.06 to 0.24 inch) higher than the 12 o’clock setting and within 1.6 to 6.0 mm (0.06 to 0.24 inch) of each other. 3.
2. Grasp the end of the blade using a rag or thickly-padded glove. 3. Remove the blade bolt, anti-scalp cup, and blade from the spindle shaft (Figure 16). DANGER If the blade is allowed to wear, a slot will form between the sail and flat part of the blade (Figure 17). Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to yourself or bystanders. • Inspect the blade periodically for wear or damage.
Servicing the Front Roller Note: Position the ends of the blade slightly lower than the center, and the cutting edge lower than the heel of the blade. This blade produces a good quality of cut and requires minimal power from the engine. By contrast a blade that is higher at the ends than the center, or if cutting edge is higher than the heel, the blade is bent or warped and must be replaced. Inspect the front roller for wear, excess wobble, or binding.
Assembling the Front Roller 1. Storage Press the first bearing into the roller housing (Figure 20). Press on the outer race only or equally on the inner and outer race. 2.
