Loading Machines

Use extreme caution when loading units on trailers or
trucks. One full width ramp that is wide enough to
extend beyond the rear tires is recommended instead of
individual ramps for each side of the unit (Figure 39).
The lower rear section of the tractor frame extends
back between the rear wheels and serves as a stop for
tipping backward. Having a full width ramp provides
a surface for the frame members to contact if the
unit starts to tip backward. If it is not possible to use
one full width ramp, use enough individual ramps to
simulate a full width continuous ramp.
The ramp should be long enough so that the angles
do not exceed 15 degrees (Figure 39). A steeper angle
may cause mower components to get caught as the unit
moves from ramp to trailer or truck. Steeper angles
may also cause the unit to tip backward. If loading on
or near a slope, position the trailer or truck so it is on
the down side of the slope and the ramp extends up the
slope. This will minimize the ramp angle. The trailer or
truck should be as level as possible.
Important: Do Not attempt to turn the unit while
on the ramp; you may lose control and drive off
the side.
Avoid sudden acceleration when driving up a ramp and
sudden deceleration when backing down a ramp. Both
maneuvers can cause the unit to tip backward.
WARNING
Loading a unit onto a trailer or truck increases the
possibility of backward tip-over and could cause
serious injury or death.
• Use extreme caution when operating a unit on
a ramp.
• Ensure the ROPS is in the up position while
using the seat belt when loading the machine.
Ensure the ROPS will clear the top of an
enclosed trailer.
• Use only a single, full width ramp; Do Not use
individual ramps for each side of the unit.
• If individual ramps must be used, use enough
ramps to create an unbroken ramp surface
wider than the unit.
• Do not exceed a 15 degree angle between ramp
and ground or between ramp and trailer or
truck.
• Avoid sudden acceleration while driving unit up
a ramp to avoid tipping backward.
• Avoid sudden deceleration while backing unit
down a ramp to avoid tipping backward.

Operating Tips

Fast Throttle Setting
For best mowing and maximum air circulation, operate
the engine at the fast throttle position. Air is required
to thoroughly cut grass clippings, so do not set the
height-of-cut so low as to totally surround the mower
by uncut grass. Always try to have one side of the
mower free from uncut grass, which allows air to be
drawn into the mower.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure the
cutting height of the mower does not scalp any uneven
ground. However, the cutting height used in the past is
generally the best one to use. When cutting grass longer
than six inches tall, you may want to cut the lawn twice
to ensure an acceptable quality of cut.
Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade.
Cutting more than that is not recommended unless
grass is sparse, or it is late fall when grass grows more
slowly.
