MOW: Mow the lawn to shorter than the normal cut height
(approximately 2" tall)
DRY: Be sure grass is dry. Wet conditions can cause in-
creased damage to healty grass.
SET DEPTH: With engine off, set the raking depth so that the
blades just touch on a flat surface (i.e. driveway, or sidewalk).
START ENGINE: See Page 5.
ENGAGE BLADES: Pull back on the bail on the operators
handle. NOTE: When engaging the blades in heavy load
conditions (i.e. heavy thatch, or very uneven turf), push down
on the operators handle lifting the front wheels slightly.
Engage the blades. Slowly lower the unit into the turf.
SLICE: Verti-cut a small test area and examine the results.
Some thatch and cut stems should be removed and deposited
on top of the healthy grass. Grass runners should be cut and
ready for removal. If excessive damage occurs to healthy
grass, adjust the blade depth to decrease damage. Continue
raking the yard, working in one direction (i.e. north-south, or
east-west). NOTE: If a large drop in engine RPM occurs, or
the unit pulls you forward and bounces during operation the
blade depth is set too low.
REMOVE THATCH/STEMS: After verti-cutting, a layer of
thatch and cut stems will be deposited over the top of the lawn.
We suggest the use of a lawn vacuum or wheeled blower for
collection and removal of the thatch/stems.
