OPERATION

Place the motion control lever in neutral. Release the parking brake and let the clutch/brake slowly return to operating position.

Allow one minute for transmission to warm up.This can be done during the engine warm up period.

Theattachmentscanalsobeusedduringtheenginewarm- up period after the transmission has been warmed up.

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 Adjustments section of this manual.

PURGE TRANSMISSION

CAUTION: Never engage or disengage freewheel lever while the engine is run-

ning.

To ensure proper operation and performance, it is recom- mended that the transmission be purged before operating tractor for the fi rst time. This procedure will remove any trapped air inside the transmission which may have de- veloped during shipping of your tractor.

IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.

Place tractor safely on a level surface - that is clear and open - with engine off and parking brake set.

Disengage transmission by placing freewheel control in freewheeling position (See “TOTRANSPORT” in this section of manual).

Sitting in the tractor seat, start engine. After the engine is running, move throttle control to slow position. With motion control lever in neutral (N) position, slowly dis- engage clutch/brake pedal.

CAUTION: At any time, during step 4, there may be movement of the drive wheels.

Move motion control lever to full forward position and hold for fi ve (5) seconds. Move lever to full reverse position and hold for fi ve (5) seconds. Repeat this procedure three (3) times.

Move motion control lever to neutral (N) position. Shut- off engine and set parking brake.

Engage transmission by placing freewheel control in engaged position (See “TO TRANSPORT” in this sec- tion of manual).

Sitting in the tractor seat, start engine. After the engine is running, move throttle control to half (1/2) speed. With motion control lever in neutral (N) position, slowly disengage clutch/brake pedal.

Slowly move motion control lever forward, after the tractor moves approximately five (5) feet, slowly move motion control lever to reverse position. After the trac- tor moves approximately five (5) feet return the mo- tion control lever to the neutral (N) position. Repeat this procedure with the motion control lever three (3) times.

Your transmission is now purged and now ready for normal operation.

MOWING TIPS

Mower should be properly leveled for best mowing per- formance. See “TO LEVEL MOWER HOUSING” in the Service and Adjustments section of this manual.

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

If grass is extremely tall, it should be mowed twice to reduce load and possible fi re hazard from dried clip- pings. Make first cut relatively high; the second to the desired height.

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

Always operate engine at full throttle when mow- ing to assure better mowing performance and proper discharge of material. Regulate ground speed by se- lecting 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 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 biode- grade 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 the newly cut area will not be exposed to direct sunlight.

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. 15). For extremely heavy mulching, re- duce your width of cut on each pass and mow slowly.

MAX 1/3

FIG. 15

Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings. When doing a second cut, mow across or perpendicular to the first cut path.

Change 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.
