FIG. 14 MULCHING MOWING TIPS IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. • The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recutting action of the blades. • Avoid cutting your lawn when it is wet. Wet grass tends to form clumps and interferes with the mulching action. The best time to mow your lawn is the early afternoon. At this time the grass has dried and the newly cut area will not be exposed to the direct sun. • For best results, adjust the mower cutting height so that the mower cuts off only the top one-third of the grass blades (See Fig. For extremely heavy mulching, reduce your width of cut and mow slowly. 4 - Replace blades more often when mowing in sandy soil. 5 - If equipped with adjustable system. 6 - Not required if equipped with maintenance-free battery. 7 - Tighten front axle pivot bolt to 35 ft. -lbs. Do not overtighten. GENERAL RECOMMENDATIONS The warranty on this tractor does not cover items that have been subjected to operator abuse or negligence.
