It may also be necessary to reduce ground speed and/or run the lawn mqwer over the area a second time. For extremely heavy cutting, reduce the width of cut by overlapping previously cut path and mow slowly. For better grass bagging and most cutting conditions, the engine speed should be set in the fast position. When using a rear discharge lawn mower in moist, heavy grass, clumps of cut grass may not enter the grass catcher. Reduce ground speed (pushing speed) and/or run the lawn mower over the area a second time. If a trail of'clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass. Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will collect less grass. To prevent this, regularly hose catcher off with water and let dry before using. Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and extend engine life. MULCHING MOWING TIPS IMPORTANT: For best ll_erfo_, keep mower housing free of built-up grass and trash. See "Cleaning" in Maln[enanca section of this manual. • The special mulching blade will recut the grass clippingsmany Umes and reduce them in size so that as they fall onto the lawn they w111 disperse into the grass and not be noticed. Also, the mulched grass will blodegrade quiddy to provide nutrientsfor the lawn. Always mulch with your highest engine (blade) speed as this willprovide the best recuttingaction of the blades. • Avoid cuttingyour lawn when it is weL Wet grass tends to form dumps and interferes with the mulching action. T_ best lime 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 resuits, adjust the lawn mower cutting height so that the lawn mower cuts off only the top one-third of the grass blades. Ifthe lawn is overgrown it will be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of mulched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously cut path and mow slowly. • Certain types of grass and grass conddJons may require that an area be mulched a second time to completely hide the dippings.Whendoinga secondcut,mow across or perpendicular to the first cutpath. • ChangeyourcuWng patternfromweekto week. Mow north to south one week then change to east to west the next week. This will help prevent matting and greJningof the lawn. /3 9 MA,NTENANCESC.EDULE FILL IN DATES ___,,,,_o"._._"_J_" G_,/^ _u/__ _ _,_,/c.,_u_ DATES Check forLoose Fasteners CleanlinspantGrass Catcher l/ I,/ M cleanLawnMower O (Power.Propelled Clean Under DriveMowers) Cover !/ Check ddve belt/pulleys li/ RE (Power-PropelledMowers) Check/Sharpen/ReplaceBlade LubricationChart CleanBattery/Rasberge IE_c st_ Mow_I NEc_ F_J_o, L_t ChangeEngleeOa ?

Care should be taken to keep the blade balanced. An unbalanced blade will cause eventual damage to lawn mower or engine. • The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower. • To check blade balance, drive a nail into a beam or wall. Leave about one inch of the straight nail exposed. Place center hole of blade over the head of the nail. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced.

DRIVE WHEELS Check front drive wheels each time before you mow to be sure they move freely. The wheels not tuming freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free drive wheels; If necessary to clean the drive wheels, check both front wheels. • Remove hubcaps, hairpin cotters and washers. • Remove wheels from wheel adjusters. NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oH. Change the oil after every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year. Check the crankcase o'd level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level. 12 TOCHANGEENGINE OIL NOTE: Beforetippinglawnmowerto drain oil,drainfueltankby runningengineuntil fuel tank is empty. • Disconnect spark plug wire from spark plug and place wire where it cannot come in contact withspark plug. • Remove engine oil cap; lay aside on a dean surface. • Tip lawn mower on its side as shown and drain oil into a suitable container.

Fold backward Mowingposition ENGINE FUEL SYSTEM IMPORTANT: It is importantto prevent gum deposits from formingin essential fuel system parts such as carburetor,f fuel filter,fuel hose or tank during storage. Also, experience indicates that alcohol blended fuels ( called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage.
