Exmark MPKA21 Lawn Mower User Manual


 
Operation
• Mowing with the Grass Bag
WARNING
A worn grass bag could allow small stones
and other similar debris to be thrown in the
operator’s or bystander’s direction. Thrown
objects can result serious personal injury or
death to the operator or bystanders.
Check the grass bag frequently. If it is
damaged, install a new Exmark replacement
bag.
Cut the grass until the bag is full.
Note: Do Not overll the bag.
• Removing the Grass Bag
1. Stop the engine and wait for all moving parts
to stop.
2. Raise the discharge door handle and move
it forward to engage the pin with the catch
(Figure 14).
3. Grasp the handles at the front and the rear of
the bag and lift the bag off the lawn mower.
4. Gradually tip the bag forward to empty the
clippings.
5. To install the bag, refer to the Installing the
Grass Bag section.
DANGER
If the discharge door does not close
completely, the lawn mower could throw
objects. Thrown objects can result serious
personal injury or death to the operator or
bystanders.
• Never open the door to the discharge
opening when the engine is running.
• If you cannot close the door because the
grass clippings clog the discharge area,
stop the engine and gently move the
discharge door handle back and forth
until you can close the door completely. If
you still cannot close the door, remove the
obstruction with a stick, not your hand.
DANGER
If the discharge door does not close
completely, the lawn mower could throw
objects. Thrown objects can result serious
personal injury or death to the operator or
bystanders.
Never open the door on the discharge tunnel
when the engine is running.
Operating Tips
• Review the Safety section and read this manual
carefully before operating the lawn mower.
• Set the engine speed to the fastest position for
the best cutting results.
• Maintain a sharp blade throughout the cutting
season. Periodically le down nicks on the blade.
Replace the blade when necessary with an original
Exmark replacement blade.
• Clean the air lter frequently. Mulching stirs up
more clippings and dust which clogs the air lter
and reduces engine performance.
Cutting Grass
• Grass grows at different rates at different times
of the year. In the summer heat, it is best to
cut grass at the 2 1/4 inch (57 mm), 2 3/4 inch
(70 mm), or 3 1/4 inch (83 mm) cutting height
settings. Cut only about a third of the grass blade
at a time. Do Not cut below the 2 1/4 inch (57
mm) setting unless the grass is sparse or it is late
fall when grass growth begins to slow down.
• When cutting grass over 6 inches (15 cm) tall,
rst mow at the highest cutting height setting and
walk slower; then mow again at a lower setting for
the best lawn appearance. If the grass is too long
and the leaves clump on top of the lawn, the lawn
mower may plug and cause the engine to stall.
• Alternate the mowing direction. This helps
disperse the clippings over the lawn for even
fertilization.
If the nished lawn appearance is unsatisfactory,
try one or more of the following:
• Sharpen the blade.
• Walk at a slower pace while mowing.
• Cut the grass more frequently.
