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
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.)

mance. it is recommended that the
transmission be purged before operating

remove any trapped air inside the trans­
mission which may have developed during
shipping of your tractor.

require removal for service or replacement,
it should be purged after reinstallation
before operating the tractor.
