OPERATION
ADJUSTING BLADE DEPTH
The depth of the blades can be raised or lowered by rotating the knob on the top of
the adjustment lever. The blades are lowered by rotating the knob clockwise, and
raised by rotating the knob counter-clockwise. The relative depth of the blades can be
gauged by using the depth scale located on the right front corner of the engine base.
With new blades installed the depth can be estimated as follows: 2.5 on the scale is
even with the ground, 3is equal to 0.25" deep, and 3.5 is equal to 0.5" deep
RAKING/SLICING TIPS
Before beginning, it is best to evaluate the condition of the lawn by cutting one or more core
samples from 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.
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).
SLOPES: Rake slopes across not up and down. 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 unit’s 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.
SLICING / OVERSEEDING: Mow the lawn to shorter than the normal cut height before
starting (i.e. approximately 2" tall for fescue grass). For the best result, Slice/Overseed in criss-
cross pattern (See Fig. 1 and See Fig 2).
FOLDING HANDLE
This unit is equipped with a folding upper handle for easier storage and transportation. The handle can be folded by
sliding the handle lock loops (item 28) up. This releases the upper handle, allowing it to be folded over the unit.
BLADE POSITION & DEPTH CONTROL LEVER
The blades can be raised or lowered into the ground by height adjustment lever on the
engine base. The height adjuster lock lever must be pushed back against the adjustment
lever in order to lower the blades into the ground. The resulting blade depth can be
adjusted higher or lower.
See ADJUSTING BLADE DEPTH.

SPRING TINE CONVERSION
If are converting your Power rake to a spring tine reel, you will need to
replace the spacer on the control lever to accommodate for the tine. First
remove the clip (item 18), then unscrew the yoke (item 17), remove the
washer (items 69) and insert the spacer (item 75) in front of the spring.
Reassemble in reverse order.

PR & OS Owner’s Manual
RAKING OPERATION-FLAIL REEL
NOTE: Must have the flail reel assembly (350112) for this operation.
MOW: Mow the lawn to it's normal cut height.
DRY:Be sure grass is dry. Wet conditions can cause increased damage to healthy 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 General Safety and operation manual.
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.
RAKE: Rake a small test area and examine the results. Thatch should be removed and
deposited on top of the healthy grass. 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: After raking, a layer of thatch will be deposited over the top of the lawn.
This thatch must be removed prior to any fertilizing, seeding, or watering of the lawn. We
suggest the use of a lawn vacuum or wheeled blower for collection and removal of the thatch.
RAKING OPERATION-SPRING REEL
NOTE: Must have the spring tine reel assembly (350354) for this operation.
MOW: Mow the lawn to it’s normal cut height. Tall grass will not leave a manicured look when the
dethatching job is complete.
DRY: Be sure grass is relatively dry. Wet conditions can cause increased damage to healthy grass.
SET DEPTH: With engine off, set the raking depth so that the spring tines are just above touching the
flat surface (i.e. driveway, or sidewalk) the units height is being adjusted on. NOTE: Allowing the
spring tines to have substantial contact with the ground will cause premature wear and failure of the
spring tines.
START ENGINE: See General Safety and operation manual.
ENGAGE TINES: Pull back on the bail on the operators handle. NOTE: When engaging the spring
tines 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 spring tines. Slowly lower the unit into the turf.
RAKE: Rake a small test area and examine the results. Thatch should be removed and deposited on
top of the healthy grass. If excessive damage occurs to healthy grass, adjust the spring tine 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 spring tine depth is set too low.
REMOVE THATCH: After raking, a layer of thatch will be deposited over the top of the lawn. This
thatch must be removed prior to any fertilizing, seeding, or watering of the lawn. We suggest the use
of a lawn vacuum or wheeled blower for collection and removal of the thatch.
VERTI-CUTTING OPERATION
NOTE: Must have the slicing reel assembly (350113) for this operation.
MOW: Mow the lawn to shorter than the normal cut height (approximately 2" tall)
DRY: Be sure grass is dry. Wet conditions can cause increased damage to healthy 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 General Safety and operation manual.
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.
