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.
