PURGE TRANSMISSION

4.Move throttle control to fast position

5.Pull choke control out for a cold engine

.start attempt. For a warm engine start

attempt the choke control may not be needed.

NOTE: Before starting, read the warm and cold starting procedures below.

6.Insert key into ignition and tum key clockwise to start position and release key as soon as engine starts. Do not run starter continuously for more than fifteen seconds per minute. If the engine does not start after several attempts, push choke control in, wait a few minutes and try again. If engine still does not start, pull the choke con- trol out and retry.

WARM WEATHER STARTING (500 F and above)

7.When engine starts, slowly push choke control in until the engine begins to run smoothly. If the engine starts to run roughly, pull the choke control out slightly for a few seconds

and then continue to push the control in slowly.

The attachments and ground drive can now be used. If the engine does not accept the load, restart the engine and allow it to warm up for one minute using the choke as described above.

COLD WEATHER STARTING (500 F and below)

7.When engine starts, slowly push choke control in until the engine begins to run smoothly. Continue to push the choke control in small steps allowing the engine to accept small changes in speed and load, until the choke control is fully in. If the engine starts to run roughly, pull the choke control out slightly for a few seconds and then continue to push the control in slowly. This may require an engine warm-up period from several seconds

to several minutes, depending on the temperature.

AUTOMATIC TRANSMISSION WARM UP

Before driving the unit in cold weather, the transmission should be warmed up as follows:

1.Be sure the tractor is on level ground.

2.Release the parking brake and let the brake slowly return to operating posi- tion.

3.Allow one minute for transmission to

warm up. This can be done during the engine warm Lip period.

The attachments can be used during the engine warm-up period after the transmission has been warmed up and may require the choke control be pulled out slightly.

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 sectiqn of this manual).

PURGE TRANSMISSION

ACAUTION: Never engage or dis- engage freewheelleverwhile the engine is running.

To ensure proper operation and per- formance, it is recommehdedthat the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the trans- mission which may have developed during shipping of your tractor.

IMPORTANT: Should your transmission require rernoval for service or replace- ment, it should be purged after reinstall- ation before operating the tractor.

1.Place tractor safely on a level surface

- that is clear of objects and open - with engine off and parking brake set.

2.Disengage transmission by placing freewheel control in disengaged posi- tion (See "TO TRANSPORT" in this section of manual).

3.Sitting in the tractor seat, start engine. After the engine is running, move throttle control to slow position. Disen-

1\.gage parking brake.

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

4.Depress forward drive pedal to full forward position and hold for five (5) seconds and release pedal. Depress reverse drive pedal to full reverse posi- tion and hold for five (5) seconds and

release pedal. Repeat this procedure three (3) times.

5.Shutoff engine and set parking brake.

6.Engage transmission by placing free- wheel control in engaged position (See "TO TRANSPORT" in this section of manual).

. 7. Sitting in the tractor seat, start engine. After the engine is running, move throttle control to half (1/2) speed. Disengage parking brake.

8.Drive tractor forward for approximately five feet then backwards for five feet. Repeat this driving procedure three times.

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

MOWING TIPS

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

Mower should be properly leveled for best mowing performance. See "TO LEVEL MOWER HOUSING" in the

.Service and Adjustments section of this manual.

The left hand side of mower should be used for trimming.

Drive SO that clippings are discharged onto the area that has already been cut. Have the cut area to the right of the tractor. This will result in a more even distribution of clippings and more uniform cutting.

When mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, driveways, etc. After one or two rounds, mow in the opposite direction making left hand turns until finished.

If grass is extremely tall, it should be mowed twice to reduce load and pos-

. sible fire hazard from dried clippings. 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 undesir- able clumps. Allow grass to dry before mowing.

Always operate engine at full throttle when mowing to assure better mow- ing performance and proper discharge of material. Regulate ground speed by selecting a low enough speed 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 at- tachment being used.
