As the saying goes
April showers bring May flowers but the rains also bring grass,
trees and weeds. And as spring gives way to summer, grass mowing
season swings into full gear.
Just about everyone is
affected by this explosion of vegetation growth, which
accompanies each summer, even people without front lawns or back
yards. Because while the lawns grow shaggy, so too does the
vegetation along the highways and roads. Not much thought is
given by the public to the maintenance of roadsides, but this
vegetation has the potential to cause safety hazards. Tree limbs
can obstruct traffic signs and signals preventing the motorist
from following proper driving etiquette; and tall grasses can
block intersections, hiding cars and pedestrians from the view
It is important for roadside maintenance crews
to use the proper equipment to control the vegetation. The
following is a round up of mowers and tree trimmers available on
the market today.

clean, finished cut similar to that of a chain saw. Cut limbs
fall to the ground thus preventing them from being thrown about,
presenting a danger to pedestrians and property.
