1. Warning—Do not touch hot surface.

This manual identifies potential hazards and provides safety messages. These messages are identified by the word WARNING or CAUTION. The WARNING symbol identifies hazards that could cause serious personal injury or death if the recommended precautions are not taken. The word IMPORTANT draws attention to important engineering information and the word NOTE highlights general information that requires special attention. Before installing and operating this attachment, refer to the Operator's Manual for safety information.

Installation

Unassembled Parts

Use the parts list below to verify that all parts have been shipped.

For greater traction, a counterweight kit (100-6442) can be added to the front of the machine. Note: If the machine has a front lift system or snow blower, the counterweight kit will not fit due to physical interference.

Attaching the Aerator Cylinder

Parts needed for this procedure:

• 1. Aerator Cylinder Assembly

Figure 3: Attaching the Aerator Cylinder

[Diagram showing the attachment of the aerator cylinder]

Procedure

Note: Identify the left and right side of the machine from the normal operating position.

1. Remove any attachment from the rear of the machine.
2. Move the tractor backward to position it in front of the attachment adapter. Lower the tractor adapter.
3. Raise the tractor adapter into the attachment adapter.
4. Rotate the locking lever to the right to lock the adapters together.

2. Adjusting the Arm Assembly

No parts required.

Procedure

1. After securing and locking the attachment to the tractor, raise the attachment.
2. Measure the clearance between the upper washer and the arm assembly spacer on the attachment adapter, as shown in Figure 4. Important: The clearance between the washer and the "foot" must be 1.5 to 2.0 mm (0.060" to 0.080").

3. 1.5 to 2.0 mm (0.060" to 0.080") Clearance

3. Completing the Installation

No parts required.

Procedure

Before using the aerator, review the following material and keep it in a convenient place:

Operation

Checking and Cleaning the Aerator Cylinder

When the aeration job is complete, clean the machine thoroughly. Since this machine is primarily used in sand, which causes significant friction and wear, the sand must be rinsed off after each use. If the machine is cleaned frequently (before sand builds up and "sets"), you can clean it with a hose, without the "nozzle." Important: Do not use high-pressure water for cleaning the machine. A high-pressure stream can force sand and other materials into sliding surfaces, causing severe friction and wear.

Note: If the attachment adapter "sticks" to the tractor adapter, insert a small pry bar or screwdriver into the release slot to separate the components.

Operating Tips

• Before starting aeration with the attachment, find an open area and practice starting, stopping, raising, lowering, and aerating. This practice will help you become familiar with the operation and control of the aerator cylinder.
• Maintain a straight path while aerating. Do not turn while the aerator blades are in the ground.
• Drive the tractor at a slow, steady pace to achieve uniform aeration.
• When you reach the end of the turf (green), raise the aerator cylinder before turning or stopping. The aerator cylinder must be fully raised before turning.
• Check the turf (green) for obstacles, such as sprinkler heads or protruding objects, that could be damaged or cause damage to the aerator cylinder.
• Adjust the penetration depth by adjusting the lift/lower valve and comparing it to the aerator cylinder depth indicator. A Variable Rate Kit is available for precise adjustment of the penetration depth.

Maintenance

Lubricating the Attachment Adapter

If the locking lever on the attachment adapter does not move freely and easily, apply a thin layer of grease to the area shown in Figure 6.

Adjusting the Compression Springs and Ball Joints

The springs and ball joints are factory-adjusted. However, if new parts are installed or parts are removed for any reason, the length of the springs and ball joints must be adjusted as shown in Figure 7.

[Diagram showing spring and ball joint adjustment]

1. 10.1 to 10.4 cm (3.98" to 4.10")

2. 4 to 4.23 cm (1.56" to 1.68")
