Glossary
These terms apply to all rotary mowers and provide a
common vocabulary about quality of cut issues.
Accelerator—a fan-like part mounted next to the blade
on some mulching mowers. The accelerator creates air
turbulence and helps evacuate clippings from the
cutting chamber. The accelerator also provides support
to the middle of the blade.

Airflow—is the movement of air created by the mower
blade. Air is pulled from under the lower edge of the
cutting chamber. This flow of air stands the grass up so
the blade can cut it. The grass clippings are then
directed to the discharge opening, bag, or, when
mulching, down onto the lawn. The type and speed of
blade, shape of the housing, and the amount of space
for the air to enter and exhaust determine the amount
and speed of the air.

Anti-scalp wheel—a wheel that contacts the ground
only momentarily to prevent scalping when a mower
encounters a high spot or crest in the lawn. Anti-scalp
wheels cannot prevent all scalping but they reduce the
incidence in most situations.

Bagging chute—the duct or chute that directs airflow
and grass clippings into the bag on a bagging mower.
Bagging mower—a type of mower that collects the
grass clippings in a hopper or bag.
