TO OPERATE ON HILLS
CAUTION: Do not drive up or down hills with
slopes greater than 10˚ and do not drive
across any slope.
• Use a slow speed before starting up or down hills.
• Avoid stopping or changing speed on hills.
• If slowing is necessary, move Travel-Steering
Control Levers to slower position.
• If stopping is absolutely necessary; use
Travel-Steering Control Levers to hold machine
on hill as it may roll down the hill in neutral.
• Do not park on hills.
• To restart movement, slowly move
Steering-Control Levers forward.
STOPPING
Brake Operation
This tractor uses hydrostatic braking, through the
transmission, to slow the tractor.
Stopping the Ground Drive
• Bring Steering-Control Levers back toward
neutral to slow the tractor.
• To stop the tractor drive, move the
Steering-Control Levers into the neutral position.
Stopping the Engine
• Move throttle control to slow position and allow
engine to idle for 30 seconds.
NOTE: Failure to move throttle control to slow position
and allowing engine to idle before stopping may cause
engine to "Backfire".
• Turn ignition key to "OFF" position and remove
key. Always remove key when leaving tractor to
prevent unauthorized use.
IMPORTANT: Leaving the ignition in any other position
than "OFF" will cause the battery to be discharged.
NOTE: Under conditions when tractor is standing idle
with the engine running, hot engine exhaust gases may
cause "browning" of grass. To eliminate this possibility,
always stop engine when stopping tractor on grass
areas.
CAUTION: Always stop tractor completely, as
described above, before leaving the operator's
position for any reason.
TO TRANSPORT THE MOWER
IMPORTANT: Never push or pull (tow) the unit with
another vehicle. Use a truck or trailer when
transporting or transmission damage can occur.
• Disengage PTO.
• Raise attachment lift to highest position with
attachment lift control.
• When pushing your tractor, be sure the
transmission dump valves are OPEN.
• Do not push tractor at more than five (5) mph.
• To protect engine cover when transporting your
tractor on a truck or a trailer, be sure engine cover
is closed and secured to tractor. Use an
appropriate means of tying hood to tractor (rope,
cord, etc.).
FOR BEST MOWING RESULTS
• Mower should be properly leveled for best
mowing performance. See Deck Leveling in
Service and Adjustments.
• The left side of mower should be used for
trimming.
• Drive so that clippings are discharged onto the
area that has been cut. Keep the cut area to the
right of the machine. This will result in a more
even distribution of clippings and more uniform
cut.
• When mowing large areas, start by turning to the
right so the 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.
• If grass is extremely tall, it should be mowed
twice to reduce load and possible fire hazard from
dried clippings. Make first cut relatively high; the
second to the desired height.
• Do not mow when grass is wet. Wet grass will
clog mower and leave undesirable clumps. Allow
grass to dry before mowing.
• Always operate engine at full throttle when
mowing to assure better mowing performance
and proper discharge of material. Regulate
ground speed by using the Steering Control
Levers.
• When operating attachments, select a ground
speed that will suit the terrain and give best
performance of the attachment being used.
