IMPACT
SPRINKLER-45
Model 53721
Installing your Impact Sprinkler:
1. Dig out soil to a depth that
positions top of sprinkler at
ground level.
2. Connect water supply to either
bottom or side inlet.*
3. Seal unused inlet with plug
included.
4. Fill hole around sprinkler with
gravel, covered by layer of soil.
*In cold climates, protect sprinkler
from freeze damage by installing a
Toro Drain valve (sold separately,
Model 53740) to bottom inlet.
For new installations, avoid dry
spots and areas of over-watering by
spacing sprinklers so their spray
patterns overlap. Use the guidelines
in the accompanying chart and
position sprinklers as shown for
optimum coverage.

Performance and Nozzle Selection Chart
Match spray pattern to your layout
Adjust sprinkler to t your layout by selecting
full or part circle spray patterns.
Full
Full Circle: Flip trip lever up
to allow sprinkler to rotate 360°.
Part Circle: Flip trip lever
down. Move adjuster collars
apart. The space between the
collars determines the arc of a
circle pattern the sprinkler will
water (20° to 340°).
Ensuring Even Coverage
To ensure that each area of your
lawn receives the same amount of
water (uniform coverage), install
the nozzle indicated in the
adjacent chart to correspond with
the full or part circle spray pattern
you have set. Toro nozzles feature
Matched Precipitation Rates to
allow sprinklers with different
patterns to be zoned together,
with each delivering matching
amounts of water.
Replacing Nozzles
1. Remove top cover.
2. Pull the rotor arm aside to
expose the nozzle.
3. Pull the nozzle tab toward you,
then push down to release the
nozzle.
4. Remove the nozzle and replace
with a new one.
5. Turn the nozzle tab clockwise
to lock the new nozzle in place.
Note: When using the orange or
red low-ow
nozzles, move

spray distance
(radius) up to
25%, with the

turn the spray
reduction screw
clockwise into the stream,
counterclockwise to increase it again.
