1. Assemble seven spring tines to the top of the frame  
tube. Use a 5/16" x 1-1/2" hex bolt, two 3/8" flat  
washers and a 5/16" nylock nut for each spring tine.  
Place one 3/8" flat washer on top of the frame tube  
and the second 3/8" flat washer on top of the spring  
tine. See figure 1.  
1. Assemble a conduit clamp onto each end of the  
sweeper height adjustment tube so that the straight  
part of the clamp is on top of the tube. See figure 3.  
2. Remove the hitch brackets and the bolts, if present,  
from the ends of the sweeper's hitch tubes. Slide the  
transport hook onto the L.H. hitch tube as shown in  
figure 3.  
nOTE: On sweepers smaller than 42", use only five spring  
tines.  
3. Reassemble the hitch brackets and bolts to the hitch  
tubes. Refer to your sweeper owner's manual.  
2. Assemble a vinyl cap onto each end of the frame  
tube. See figure 1.

height adjustment handle to about the middle of it's  
adjustment range.  
5. Place the dethatcher in front of the sweeper housing,  
underneath the hitch tubes.  
6. Connect the dethatcher to the conduit clamp using  
two 5/16" x 1-3/8" clevis pins, 5/16" washers and  
3/32" hair cotter pins. See figure 4.  
3. Assemble a 1/2" washer, the wheel, another 1/2"  
washer and a 1/2" plain jam nut onto the 1/2" x 3-1/2"  
hex bolt. See figure 2.  
4. Insert the bolt through the welded bracket and  
assemble a 1/2" nylock jam nut onto the bolt. Adjust  
nuts so that there is no end play in the wheel and  
then tighten securely against the welded bracket.  
Make sure the wheel still turns freely. See figure 2.

9. Assemble the keeper brackets (bend to the inside)  
to the sweeper's hitch tube, outside of the conduit  
clamps. Use a u-bolt and two 1/4" nylock nuts  
offset tube. This prevents you from offsetting the sweeper.  
per bracket. Position the keeper brackets against  
the sides of the conduit clamps, approximately  
perpendicular to the ground. Tighten the nylock nuts  
without bending the keeper brackets. See figure 5.  
1. Assemble the four bearings to the two .8 x 1 x 2.55"  
spacers and then slide each through a clamp. See  
figure 7.

OPERATiOn  
RAiSinG/lOWERinG THE DETHATCHER  
1. To raise the dethatcher for transport, lift up on the  
front of the dethatcher and secure it with the transport  
or SMARTSweep hook. Lower the dethatcher by  
releasing the hook.

SETTinG THE OPERATinG POSiTiOn  
1. The operating height of the dethatcher is controlled  
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.  
3/32" HAIR  
COTTER PIN  
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.  
FiGuRE 9  
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.  
SMARTSWEEP HOOK  
STORAGE  
1. Always store in a dry area, and coat exposed metal  
with light oil when not in use.
