GENERAL OPERATION
Daily Inspection
1.
Always set the parking brake, shut off 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 power rake on a level
surface, with the engine shut off and all fluids cold.
2. Perform a visual inspection of the power unit and
power rake. Look for loose or missing hardware,
damaged components, damaged or missing
carbide tips, or signs of wear. Inspect drive belts.
Belts should be in good condition.
3.
Inspect hydraulic hoses, hydraulic fittings, and
fuel lines to ensure tight, leak free connections.
Check the power rake’s hydraulic oil level.
4. 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
fluid or service system as required.
5. Refer to the power unit operator’s manual. Test
the power unit’s operator safety interlock system.
Attaching
1. Adjust the power rake height until the indicator (A)
is located in the attaching zone^ on the height
adjustment decal.
2.
A
Raise the power unit’s front hitch to the maxi-
mum height and engage the weight transfer
system* (if equipped).
3. Drive the power unit slowly forward into the hitch
arms of the power rake. Align the lift arms of the
power unit with the power rake hitch arms by
raising or lowering the front hitch and complete
the engagement.
4. Once completely engaged, close the front hitch
locking lever.*
5.
Engage the parking brake* and shut off the engine.
6. Place the attachment belt onto the PTO drive
pulley on the power unit. Ensure the belt is prop-
erly seated in each pulley.
7. Engage the PTO spring tension lever* on the
power unit.
8. 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.
Detaching
1. Adjust the power rake height until the indicator
is located in the attaching zone^ on the height
adjustment decal.
2. Park the power unit on a level surface and set
the parking brake.*
3. Lower the power rake to the ground.
4.
Shut off power unit engine.
5. Disengage the PTO tension spring.
6. Remove the attachment belt from the PTO drive
pulley of the power unit.
7. Disconnect the hydraulic quick couplers from the
power unit and store the hose ends in the holes
in the main frame.
8. Disengage the front hitch locking lever*.
9. Restart the power unit and back slowly away from
the power rake.
* Refer to power unit operator’s manual for operation of power
unit controls.
^ Attaching zone is set for the standard lift arm height of Ventrac
4000 series power units. Variables such as tire size, tire infla
-
tion, and attempting to attach on an uneven surface will affect
the proper location of the attaching zone.
