VERTI-CUTTING OPERATION
SET DEPTH:
With engine off, set the raking depth so that the blades just touch on a flat surface (i.e. driveway, or sidewalk).
ENGAGE BLADES:
Pull back on the bail on the operator
’s handle.
NOTE:
When engaging the blades in heavy load conditions (i.e.
heavy thatch, or very uneven turf), push down on the operator
’s 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.
*****TIPS*****
MOW
Mow the lawn to its normal cut height.
DRY
Be sure grass is dry. Wet conditions can cause increased damage to healthy grass.
INSPECT
Check the lawn before beginning work. Remove all rocks, wire, string, or other objects that can present a hazard during work prior
to starting.
IDENTIFY
Mark all fixed objects to be avoided during work, such as sprinkler heads, water valves, buried cables, or clothes line anchors, etc.
THATCH
Thatch is a dense layer of dead grass, clippings, and roots that builds up over time at the base of the lawn preventing air, water,
and fertilizer from reaching the soil. This can cause shallow root development and make a lawn more susceptible to drought and
disease. Thatch also provides an ideal environment for insects to hide and multiply. Periodic removal of thatch will keep your lawn
in good health.
HEAVY THATCH
Lawns with an excessive amount of thatch will require multiple treatments for effective removal. Trying to remove excessive thatch
(greater than 3/4"[19 mm] deep) in one treatment will damage or destroy the living part of the lawn. It is best to remove heavy
thatch in seasonal treatments (i.e. spring, and fall).
CHECK
Before beginning, it is best to evaluate the condition of the lawn by cutting one or more core samples from the area to be treated.
A core can be cut using a piece of pvc, or metal pipe. Hammer the pipe into the ground, remove it, push the core out of the pipe
and inspect it to determine the depth of thatch in your yard.
SLOPES
Rake slopes across not up and down the slope. This is much easier and safer for the operator and is better for the lawn. Raking
across will help to reduce runoff during watering and allow the sloped ground to hold more seed, fertilizer, and water. The units
maximum operating slope is 35% or 19°.
DEPTH
The wide range of depth adjustment on your unit is provided to allow for blade wear. Setting the reel deeper will not produce
better, or quicker results. The flail reel is intended to be set so it just touches the surface on flat ground. The slicing reel should be
set even with the ground for verti-slicing work, and set to a maximum 1/2" depth for overseeding jobs. Setting the reel deeper than
this will only result in premature wear on the unit (i.e. failed belt). If you desire to work the ground deeper than the above
guidelines allow, it should be done gradually in multiple passes.
