SETTinG THE OPERATinG POSiTiOn

by the gauge wheel at the front of the dethatcher
and is not adjustable. The correct wheel position
was determined in figure 2 when you assembled the
wheel.

2. Set the sweeper to the desired operating height. (The
best height is usually with the brushes set about 1/2"
down into the grass.) Refer to your sweeper owner's
manual for sweeper.

4. Secure the two mount brackets to the inner holes of
the drawbar offset tube of the sweeper using two 5/16
x 2-1/2" hex bolts and 5/16" nylock nuts. See figure 10.
uSinG THE DETHATCHER
Regular removal of thatch is critical to the maintenance of
a healthy lawn.Thatch is layer of stems, clippings, runners,
roots and leaves that have not decayed. Excessive thatch
prevents air, water and fertilizer from reaching the roots.
The dethatcher will effectively dislodge excessive thatch
5/16" x 2-1/2"
HEX BOLT
from your lawn.
1. Start with the tractor in low gear. Vary the forward
speed to determine the best speed for maximum
dethatcher performance.
2. Use a crisscross pattern to achieve the most even
removal of thatch.
3. On slopes, always operate in an up and down
direction only.
4. Avoid extremely sharp turns.
5/16" NYLOCK NUT
5. Avoid towing the dethatcher across sudden steep
dips in the ground while dethatching. Loss of ground
contact with the gauge wheel could cause the
dethatcher to be pulled back underneath the sweeper.
FiGuRE 10
5. Slide the SMARTSweep hook onto the sweeper hitch.
Lift up the front of the dethatcher and slide it into the
two bottom hooks to secure it in the transport position.
mAinTEnAnCE
1. Before each use, check all nuts and bolts for
tightness.
2. Clean after each use to help prevent rust.
3. If rust appears on the spring tines, sand lightly and
coat with enamel paint.
