OPERATION

  

continued

16

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.

DO NOT- 

Use this machine on any surface other than a

lawn.

DO NOT- 

Use this machine on slopes in excess of 19°.

DO NOT- 

Allow persons unfamiliar with this equipment to

operate it.

DO NOT- 

Allow children to operate this equipment.

OVERSEEDING  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.

SEED: 

Spread grass seed according to the seed

suppliers directions (e.g. 10 lbs. per 1000 ft

[4.5 kg. per

93 m

])

SET DEPTH: 

With engine off, set the raking depth so

that the blades reach 1/4"-1/2"(6-12 mm) below a flat
surface (i.e. driveway, or sidewalk).

START ENGINE:

 See Page 5.

ENGAGE CLUTCH: 

Pull back on the bail on the

operators handle.  

NOTE:

 When engaging the clutch 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 clutch.  Slowly
lower the unit into the turf.

DO NOT- 

Use this machine on any surface other than a

lawn.

DO NOT- 

Use this machine on slopes in excess of 19°.

DO NOT- 

Allow persons unfamiliar with this equipment to

operate it.

DO NOT- 

Allow children to operate this equipment.

SLICE: 

Run machine over the area that has been

seeded to incorporate the seed into the soil.  If exces-
sive 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.

WATER/FERTILIZE: 

After the seed has been worked

into the soil, water and fertilize according to the seed
suppliers  directions.

VERTI-CUTTING  OPERATION

NOTE: Must have the slicing reel assembly (350113) for
this operation.
