GENERAL OPERATION
Operation - 16
GENERAL OPERATION
Daily Inspection
1.
Always set the parking brake, shut o󰀨 power unit
engine, remove the ignition key, and ensure all
moving parts have come to a complete stop before
inspecting components, or attempting any repair or
adjustment.
Park the power unit and terra rake on a level
surface, with the engine shut o󰀨 and all uids
cold.
2. Perform a visual inspection of the power unit
and terra rake. Look for loose or missing hard-
ware, damaged components, bent rake tines, or
signs of wear. Inspect hydraulic hoses, hydraulic
ttings, and fuel lines to ensure tight, leak free
connections.
3. Refer to the power unit operator’s manual.
Check the power unit’s engine oil, hydraulic oil,
cooling system, tire pressure, and fuel level. Add
uid or service system as required.
4. Refer to the power unit operator’s manual. Test
the power unit’s operator safety interlock system.
Attaching
1. Drive the power unit slowly forward into the hitch
arms of the terra rake. Align the lift arms of the
power unit with the terra rake hitch arms by rais-
ing or lowering the front hitch and complete the
engagement.
2. Once completely engaged, close the front hitch
locking lever.*
3. Engage the parking brake* and shut o󰀨 the
engine.
4. Wipe hose ends clean, and connect to the power
unit’s hydraulic quick couplers. If equipped, con-
nect the hoses and quick couplers so the red
indicators are paired together and the yellow
indicators are paired together.
5. Connect the electric plug (if equipped).
Detaching
1. Park the power unit on a level surface and set
the parking brake.*
2. Lower the terra rake to the ground.
3. Shut o󰀨 power unit engine.
4. Disconnect the hydraulic quick couplers from the
power unit and store with the hose ends on the tine
frame. Do not allow hose ends to lay in the dirt.
5. Disconnect the electric plug (if equipped).
6. Disengage the front hitch locking lever.*
7. Restart the power unit and slowly back away
from the terra rake. A side to side movement of
the steering wheel may aid disengagement.
Operating Procedure
Before operation, perform daily inspection, set the
rake tines to the desired depth, and turn o󰀨 the
power unit’s weight transfer.
Move the machine into position, angle the rake if
desired, and lower the terra rake to the ground.
Place the power unit’s primary S.D.L.A. lever in
the oat position by pushing it to the right until the
detent engages. The lever will stay in this position
until intentionally removed.
Work in the forward direction so the tines can collect
the debris and help separate it from the soil. Operat-
ing the rake at an angle will allow the tines to comb
through the loose soil while rolling the debris into a
windrow at the trailing edge of the terra rake. Move
the secondary S.D.L.A. lever to the left or right to
angle the terra rake.
When rake is angled to the left or right, pinch
points are created. Make sure there are no people
or objects present between the rake frame and the
power unit.
NOTE: the greater the angle of the rake, the more
loose material it will move into the windrow along
with the debris.
NOTE: If the tines are set too deep when leveling
and raking debris, the amount of soil being removed
will increase. Reducing the depth of the tines will
help to separate the debris from the soil so only the
debris is removed from the work area.
Multiple passes may be required to remove the
desired amount of debris.
If grass or other debris becomes lodged in the rake
tines, rake performance will be reduced. Clean the
rake tines as needed.
Raise the rake tines o󰀨 the ground when backing up.
* Refer to power unit operator’s manual for operation of
power unit controls.

GENERAL OPERATION
Operation - 17
Transport of Terra Rake
Transport the terra rake with the power unit front hitch
and terra rake raised to reduce wear of the machine
and to prevent the rake tines from catching on high
spots in the ground, rocks, or other obstacles. Travel
slowly when transporting over undulating or rough
surfaces to maintain control of power unit and to
reduce the shock to the machine.
Setting Tine Depth
The tine depth is adjusted by turning the adjustment
link. Lengthening the adjustment link will raise the
tines and shortening the adjustment link will lower
the tines. If equipped with a height adjustment cylin-
der, select the height adjustment function with the 12
volt switch and move the secondary S.D.L.A. lever
to the left or right until the desired depth is reached.
For leveling and separating debris, set the rake tines
to comb through the soil at 1/4” to 1” deep.
For spreading or leveling large amounts of loose
material, setting the rake tines deeper will allow the
rake to move more material with each pass.
Gauge Wheel Positions
The terra rake has gauge wheels that can be
adjusted for di󰀨erent applications or user preference.
Inside
mounting
position
Outside
mounting
position
Mounting the gauge wheels in the outside mounting
positions creates a wider footprint which will help
obtain a more level surface. When the rake is fully
angled in this position, the wheels are outside the
raking path of the tines and can hinder performance
when windrowing debris. In this case, the wheels
should be moved to the inside mounting positions.
Mounting the gauge wheels in the inside mounting
positions creates a narrower footprint which ensures
the wheels are not in the way when windrowing and
makes maneuverability much easier. In this position,
the ends of the rake may dig in excessively hard
when moving along a mound or ridge.
Rear Mount (3 Point Hitch) Procedures
The hitch frame on the terra rake can be reversed
for use on a power unit that is equipped with a 3
point hitch and a 3-N-1 adapter. Remove the bolt
(A) that fastens the height adjustment link to the
tine frame and the four bolts (B) that fasten the hitch
frame anchor to the tine frame.

not be used when the terra rake is mounted on the
rear 3 point hitch.
