Blade versatility
Flail Blades
Thatch is the dense layer of clippings, roots and 
stems that forms between the soil and the base of 
the grass. As thatch builds up, it prevents water, 
air and fertilizer from being absorbed into the soil. 
This causes shallow root development leading to 
vulnerability to drought and frost. Excessive thatch 
also creates an ideal environment for insects and lawn 
diseases. Power-raking with flail blades removes this 
thatch layer and restores your lawn to good health. 
Flail blades offer the most aggressive dethatching of 
all the blades offered.
Delta Blades
Delta blades were created primarily for overseeding 
existing lawn. They effectively incorporate grass 
seed into the soil.  This is an easy, reliable method for 
rejuvenating poor lawns. The delta blade is also useful 
as a vertical mower for cutting running stem grasses 
and opening up the soil to oxygen, water, nutrients 
and other chemicals. Delta blades are also beneficial 
on slopes, terraces and in high clay content soils 
where water runoff is a problem. The blades should 
be set to penetrate the soil to a depth of 
1
/
8
" to ¼" with 
a maximum penetration of ½".
Check your seed bag for the manufacture’s 
recommended depth of application.
Spring Tines
Ideal for the established lawn that is not in need of a 
complete renovation but requires dethatching (dry-
spots, fungus, etc.). Spring tines are designed to 
pluck dead grass and thatch out of the lawn without 
tearing or damaging existing root structure. With the 
flexible tines, the lawn is combed only 0.5 cm into the 
soil, so it cannot penetrate the root structure. Spring 
tines provide less aggressive dethatching than flail 
blades. NOTE: Do not use spring tines with bagger 
attachment.
