Assemble a conduit clamp onto each end of the  
sweeper height adjustment tube so that the straight

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.  
If you have a 30" sweeper, skip these steps.  
Make sure the sweeper height adjustment handle is  
still set to about the middle of it's adjustment range.  
Center the dethatcher with the sweeper.  
Assemble the keeper brackets (bend to the inside)  
to the sweeper's hitch tube, outside of the conduit

bracket. Position the keeper brackets against the sides  
of the conduit clamps, approximately perpendicular  
to the ground. Tighten the nuts without bending the  
keeper brackets. See figure 5.  
Reassemble the hitch brackets and bolts to the hitch  
tubes. Refer to your sweeper owner's manual.

OPERATION  
USING THE DETHATCHER  
HOW TO USE YOUR 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  
RAISING/LOWERING THE DETHATCHER  
To raise the dethatcher for transport, lift up on the  
front of the dethatcher and secure it with the transport  
hook. Lower the dethatcher by releasing the transport  
hook.  
excessive thatch from your lawn.  
Start with the tractor in low gear. Vary the forward  
speed to determine the best speed for maximum  
dethatcher performance.  
SETTING THE OPERATING POSITION  
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.  
Use a crisscross pattern to achieve the most even  
removal of thatch.  
On slopes, always operate in an up and down  
direction only.  
Set the sweeper to the desired operating height. (The  
best height is usually with the brushes set about ꢀ/ꢁ"  
down into the grass.) Refer to your sweeper owner's  
manual for sweeper.  
Avoid extremely sharp turns.  
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.
