control to the fast position.
• The attachments and ground drive can
now be used. If the engine does not
accept the load, restart the en gine and
allow it to warm up for one minute using
the choke as de scribed above.
COLD WEATHER STARTING ( 50° F and

control in choke position until engine
warms up and begins to run roughly.
Once rough running begins, im me -

the trans mis sion 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 re turn to operating

ing the engine warm-up period after the
trans mis sion 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
