serve more than one purpose
1) The main purpose is to keep grass
clippings and debris from being discharged
from under the deck and contained within the mower while the
OCDC is in the
closed position keeping the clippings from being blown onto areas such as
flowerbeds, mulched areas and hard
surfaces such as drives, sidewalks and
play areas. Once past the area the OCDC is returned to the
where the grass continues
to be disbursed evenly over the lawn.
2) Most OCDC's can also be partially closed as well. Since most commercial
mowers can disburse lawn clippings between 15 and 20 feet the OCDC
can be closed part way in order to control how far the clippings
mower deck and are thrown from the mower so they are kept from hard surfaces
and beautification areas that are

Design OCDC is also designed to be used as a blower unit.
the amount of air coming from under the Power Chute is enough
to create a powerful blower to clear drives, sidewalks
and patios of grass
clippings thus saving slower walking time with your hand held blower
equipment during cleanups.
4) OCDC's can also be used partially closed to keep hazards such as
gravel and other
dangerous objects from being thrown at high speed from under
the deck and into nearby by cars
and people that could be injured by flying
debris. Power Chutes are heavily used by municipal government mowing crews
and those mowing close to roadways.
