• If the grass is repeatedly mowed in the same direction, it will be “trained” so that
the striped appearance is more pronounced and longer lasting. Grooving of the
turf from the tires will occur.
• For emptying material collection systems or for any other operation involving the
mower deck, before leaving the operator station:
• Disengage the mower blades.
• Squeeze the steering controls and latch the neutral locks.
• Place the gear shift lever in neutral.
• Shut off the engine.
• Apply wheel chocks and/or engage the parking brake.
Transporting Mower
• If ramps are used, be sure they are secured to the trailer, truck bed, etc. and are
designed for the application.
• The mower should be pushed or pulled onto or off the trailer, truck bed, etc., never try
to drive it on.
• Engage the parking brake, secure mower with chocks, straps, etc.
• Make sure accessories and attachments are secured or removed.
PRODUCT CARE
Maintenance Schedule
WARNING: Before performing any maintenance or repairs, disengage the
PTO, engage the parking brake, stop the engine, and remove the key to
prevent unintended starting.
Follow the maintenance schedule given below. This chart describes service guidelines only.
Mowing
The following information will be helpful when operating your mower.
WARNING: Plan your mowing pattern to avoid discharge of materials
toward roads, sidewalks, bystanders, and the like. Also, avoid discharging
material against a wall or obstruction which may cause discharged material
to ricochet back toward the operator.
• Be sure area is clear of rocks, sticks, toys, wire or other objects that could be thrown by
the mower. Survey the entire area to be mowed. Make sure that the accessories and
attachments would be suitable for use on the terrain.
• Use care when approaching blind corners, shrubs, trees or other objects that could
obstruct vision.
• To mow grass and produce a striped pattern:
• Pick a point on the opposite side of the area to be mowed (post, tree, shrub, etc).
• If on a hillside, start at the bottom so that the turns are uphill rather
than downhill.
• Align the mower so as to head directly toward the object on the far side.
• Slowly increase the speed of the machine to match cutting conditions, terrain
and operator familiarity with the controls and keep the machine headed directly
toward the alignment object. Do not go fast as to reduce cut quality or to be
uncomfortable in controlling the speed and direction of the machine.
• When approaching the other end of a strip, slow down or stop before turning. A
U-turn is recommended.
• To prevent rutting or grooving of the turf, change the direction that the strips
are mowed by approximately 45° the next and each subsequent time that the
area is mowed.
