515196 - 1/2" Coring Tine
522361 - 3/4" Coring Tine, Thin Wall
515197 - 3/4" Coring Tine, Thick Wall
These tines are for use with aeration programs in
the Spring and Fall. Soil cores up to 4" (102mm)
in length can be removed with minimal surface
disturbance.
(Single Knife Part Numbers)
521155 - Deep Slicing Knife
515193 - Shallow Slicing Knife
Slicing knives are used for aeration and renovation
programs during all seasons. Slicing knives control
thatch by cutting through grass runners and also
have the advantage of no surface clean up after
aerating. Knives are especially helpful in that they
do not place buried seeds of noxious weeds on the
surface where they can germinate.
Slicing knives are especially recommended for ath-
letic elds. Slicing allows moisture, air and fertilizer
to be absorbed while not creating hazardous playing
conditions for athletes.
520404 - Aerating Tine
These tines are for turf building and Fall renovation
programs. These tines will thoroughly open up the
soil by penetrating deep into the ground bringing up
large amounts of soil, which then becomes top dress-
ing.
