Adjusting The Skids; Operating With The Overheat Sensor; Operating Tips - Toro Z Master Professional 7500-D Series Operator's Manual

Adjusting the Skids

For Models with Rear Discharge
Mount the skids in the lower position when operating
at heights of cut greater than 51 mm (2 inches) and
in a higher position when operating at heights of cut
lower than 51 mm (2 inches).
Adjust the skids as shown in
Figure 33
Operating with the Overheat
Sensor
The PTO disengages, an alarm sounds, and a
bar graph displays the engine temperature when it
reaches an overheat condition. The PTO does not
engage until the engine has cooled and you manually
shut off the PTO and engage it.
Note:
If the engine-coolant level is below the indicator
line on the overflow bottle when the engine is cold, the
coolant temperature gauge may not register correctly
during operation and/or the audible alarm may not
sound if the engine overheats.

Operating Tips

Using the Fast Throttle Setting
For best mowing and maximum air circulation, operate
the engine at the F
AST
thoroughly cut grass clippings, so do not set the
height-of-cut so low as to totally surround the mower
deck in uncut grass. Always try to have 1 side of the
mower deck free from uncut grass, which allows air
to be drawn into the mower deck.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that
the cutting height of the mower deck 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 15 cm (6 inches) tall,
you may want to cut the lawn twice to ensure an
acceptable quality of cut.
Cutting a Third of the Grass Blade
It is best to cut only about a third 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.
Alternating the Mowing Direction
Alternate the mowing direction to keep the grass
standing straight. This also helps disperse clippings,
which enhances decomposition and fertilization.
Mowing at Correct Intervals
Grass grows at different rates at different times of
the year. To maintain the same cutting height, mow
more often in early spring. As the grass growth rate
slows in mid summer, mow less frequently. If you
cannot mow for an extended period, first mow at a
high cutting height, then mow again 2 days later at a
lower height setting.
Using a Slower Cutting Speed
To improve cut quality, use a slower ground speed
in certain conditions.
Avoiding Cutting Too Low
When mowing uneven turf, raise the cutting height
to avoid scalping the turf.
Stopping the Machine
If you must stop the forward motion of the machine
while mowing, a clump of grass clippings may
