This unit may have sharp points. Handle with care.
Keep your eyes and mind on your vehicle/attachment and area being covered. Do not let yourself be distracted.
Stay alert for holes in the terrain and other hidden hazards.
Tractor braking and stability may be affected with the attachment of this unit. Be aware of changing conditions on slopes. Refer
to safety rules in your tractor owner’s manual concerning safe operation on slopes. Stay Off Steep Slopes.
Always operate up and down a slope, never across the face of a slope.
This equipment should be operated at a reduced speed on rough terrain, along creeks, ditches and on hillsides, to prevent

Keep the tractor and attachment in good operating condition and keep safety devices in place.
Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition.
The tractor and attachment should be stopped and inspected for damage after striking a foreign object. Any damage should be
repaired before restarting and operating the equipment.

Operation
Raising/Lowering the Dethatcher
1. To raise the dethatcher for transport lift up the
back until the tines are no longer in contact with
the ground.
2. To lower the dethatcher for operation, move the
Handle to the down position.
3. Do not use more than 75 lbs ballast on the Base.
Using the Dethatcher
Regular removal of thatch is a critical step for the
maintenance of a healthy lawn. Thatch is a layer of
stems, clippings, runners, roots, and leaves that has
not decayed. Excessive thatch prevents air, water,
and fertilizer from reaching the roots. The
dethatcher will effectively dislodge excessive thatch
from your lawn. Use your dethatcher in the mid-tolate Spring and/or in early Fall.
1. Your grass should be less than 3” tall for proper
tine action.
2. Start with the tractor in low gear. Vary the
forward speed to determine the best speed for
maximum performance.
3. When in use, all tines on the dethatcher should
bend to the back and “flip” the thatch forward
as it is pulled.
4. Use a crisscross pattern to achieve the most
even removal of thatch.
5. On slopes, always operate in an up and down
direction only.
6. Avoid extremely sharp turns.
7. Not for use with Zero Turn Radius Mowers.
Maintenance
1. Before each use check all nuts and bolts for
tightness.
2. Clean after each use to prevent rust. The key to
years of trouble-free service is to keep your
dethatcher clean and dry.
3. If rust should develop, sand lightly and then
paint area with enamel.
4. Periodically check all moving parts for free
movement and if necessary, lubricate with oil.
Storage
1. Be careful to store your dethatcher with the
tines pointed towards the floor or a wall. Tines
are sharp and can cause considerable damage.
2. Always store in a dry area, and coat exposed
metal with light oil when not in use.
