I^RGE TRANSMISSION
^CAUTION: Never engage or disen­
gage freewheel lever while the engine is
running.
To ensure proper operation and perfor­
mance, it is recommended that the trans­
mission 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 reinstalla­
tion before operating the tractor.
• Place tractor safely on level surface with
engine off and parfring brake set.
• Disengage transmission by placing free­
wheel control in freewheeling position
(See “TO TRANSPORT in this section
of manual).
• Sitting in the tractor seat, start engine.
After the engine is running, move throt­
tle control to slow position. With motion
control lever in neutral (N) position,
slowly disengage clutch/brake pedal.
• Move motion control lever to full fonward
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 procedure there will b(
no movement of drive wheels. Thej air is
being removed from hydraulic drivé sys­
tem.
■

position. Shut off engine and set parkin
brake.

ward; after the tractor moves approxi­
mately five (5) feet, slowly move motioi
control lever to reverse position.^After
the tractor moves approximately five (£
feet return the motion control lever to
the neutral (N) position. Repeat this pn
cedure with the motion control lever

MOWING TIPS
• Tire chains cannot be used when the
mower housing is attached to tractor.
• Mower should be property leveled for
best mowing performance. See TO
LEVEL MOWER HOUSING" in the
Service and Adjustments section of thh
manual.
• The left hand side of mower should be
used for trimming.
• Drive so that clippings are discharged
onto the area that has been cut. Have
the cut area to the right of the tractor.
This will result in a more even distribu­
tion of clippings and more uniform cut­
ting.
• When mowing large areas, start by tur
ing to the right so that clippings will dir
charge away from shrubs, fences, driv
ways, etc. After one or two rounds, mo\
in the opposite direction making left
hand turns until finished.
• If grass is extremely tall, it shoüid be
mowed twice to reduce load and possi­
ble fire hazard from dried clippings.
Make first cut relatively high; the secón
to the desired height.
