TO START ENGINE

When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine.

1.Be sure freewheel control is in the transmission engaged position.

2.Sit on seat in operating position, depress brake pedal and set parking brake.

3.Move attachment clutch to disengaged position.

4.Move throttle control to choke position. NOTE: Before starting, read the warm and cold starting procedures below.

5.Insert key into ignition and turn 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, move throttle control to fast position, wait a few minutes and try again. If engine still does not start, move the throttle control back to the choke position and retry.

WARM WEATHER STARTING (50° F and above)

6. When engine starts, move the throttle control to the fast position.

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 ( 50° F and below)

6.When engine starts, leave throttle control in choke position until engine warms up and begins to run roughly. Once rough running begins, imme- diately move the throttle control to the fast position. Engine warm-up may take from several seconds to several minutes (the colder the temperature, the longer the warm-up).

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 position.

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

• The attachments can also be used dur- ing the engine warm-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 dis- engage freewheel lever while the engine is running.

To ensure proper operation and per- formance, it is recommended that 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 removal for service or replace- ment, it should be purged after reinstall- ation before operating the tractor.

1.Place tractor safely on level surface - that is clear 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-

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.
