Operation
STARTING ENGINE
RAKING OPERATION
Like all mechanical tools, reasonable care must
be used when operating machine.
MOW: Mow the lawn to it's normal cut height
DRY: Be sure grass is dry. Wet conditions can cause in-
creased 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 above.
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 healty 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.
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.
The blades can be raised or lowered into the ground by height
adjusment lever on the engine base. The resulting blade
depth can be adjusted higher or lower.

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.
