TO START ENGINE (See Fig. 9)

When st'a_tIff_j6r,gine for'the first time or if engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine

Depress clutch/brake pedal and set parking brake. o Place gearshift lever in neutrai (N) position°

° Move attachment clutch to "DISENGAGED" position.

°Move throttle control lever to choke (N) position for cold engine start. For warm engine start, move throttle control to fast (,_) position_

°Insert key into ignition and turn keyclockwiseto"START" position and release key as soon as engine starts. Do not run starter continuously for- more than fifteen seconds per minute. If engine does not start after several attempts, move throttle control to fast (,_) position, wait a few minutes and try again..

-When engine starts, move throttle control to desired position..

=Allow engine to warm up for a few minutes before engaging drive or'attachments.

NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32°F), the carburetor fuel mixture may need to be adjusted for best engine performance_ See "TO ADJUST CARBURETOR" in the Service and Adjust- ments section of this manual..

MOWUNGTIPS

°Tire chains cannot be used when the mower housing is attached to tractor.

oMower should be properly leveled for best mowing performance° See "TO LEVEL MOWER HOUSING" in the Service and Adjustments section of this manual

oThe left hand side of mower should be used for trim- ming.

=Drive so that clippings are discharged onto the area that has been cut. Have the cut area to the right of the machine_ This will result in a more even distribution of clippings and more uniform cutting_

°When mowing large areas, start by turning tb the right

so that clippings will discharge away from shrubs, fences, driveways, etc, After one ortwo rounds, mow in the opposite direction making left hand turns until finished (See Fig. 11).

oIf grass is extremely tail, it should be mowed twice to reduce toad and possible fire hazard from dried clip- pings. Make first cut relatively high; the second to the desired heighL

°Do not mow grass when it is wet.. Wet grass will plug mower and leave undesirable clumps. Allow grass to dry before mowing.

oAlways operate engine at full throttle when mowing to assure better mowing performance and proper dis- charge of material Regulate ground speed by select- ing a low enough gear to give the mower cutting performance as well as the quality of cut desired.

°When operating attachments, select a ground speed

that will suit the terrain and give best performance of the attachment being used..

MULCHING MOWING TiPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND

TRASH. CLEAN AFTER EACH USE.

The special mulching blade will recut the grass clip- pings many times and reduce then] 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_

oAvoid 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 mowercutting height so that the mower cuts off only the top one-third of the grass blades (See Fig. 12)_ For'extremely heavy mulching, reduce your width of cut on each pass and mow slowly.

°Certain types of grass and grass conditions may re- quire that an area be mulched a second time to com- pletely hide the clippings. When doing a second cut, mew across or perpend!cular to the first cut path°

oChange your cutting pattern from week to week. Mow north to south one week then change to east to west the

next week. This will help prevent matting and graining of the lawn.
