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.Place the motion control lever in neutral. Release the parking brake and let the clutch/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 with engine off and parking brake set.

2.Disengage transmission by placing freewheel control in “transmission dis- engaged” position (See “TO TRANS- PORT” in this section of manual).

3.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 disengage clutch/brake pedal.

4.Move motion control lever to full forward position and hold for five (5) seconds. Move lever to full reverse position and hold for five (5) seconds.

Repeat this procedure three (3) times. NOTE: During this step there will be no movement of drive wheels. The air is being removed from hydraulic drive system.

5.Move motion control lever to neutral

(N) position. Shutoff engine and set parking brake.

6.Engage transmission by placing freewheel control in “transmission engaged” position (See “TO TRANS- PORT” 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. With motion control lever in neutral (N) position, slowly disengage clutch/brake pedal.

8.Slowly move motion control lever forward, after the tractor moves ap- proximately five (5) feet, slowly move

motion control lever to reverse position. After the tractor moves approximately five (5) feet return the motion control lever to the neutral (N) position. Repeat this procedure with the motion control lever three (3) times.

Your transmission is now purged and ready for normal operation.
