OPERATION

WARM WEATHER STARTING (50° F and above)

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)

When engine starts, allow engine to run with the throttle control in the choke position until the engine runs roughly, then move throttle control to fast posi- tion. 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:

Be sure the tractor is on level ground.

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.

The attachments can also be used during 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 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 first time. This procedure will remove any trapped air inside the transmission which may have de- veloped during shipping of your tractor.

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 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 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.

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 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 (See Fig. 12).
