4. Operating Instructions

Proper operation ensures effective aeration and prolongs the life of your equipment.

1. Lawn Preparation: Before aerating, mow the lawn and remove any loose clippings. If the soil is extremely hard and dry, water it down 1-2 hours prior to aeration to allow for better penetration.
2. Add Weight (Optional): To increase the depth of plug penetration, add up to 140 lbs of weight (e.g., sandbags, concrete blocks) to the aerator tray. Secure the weight with ties or straps to prevent movement.
3. Connect to Tractor: Attach the aerator to your lawn or garden tractor using the universal hitch.
4. Start Operation: Begin with the tractor's transmission in first (low) gear and the engine at low speed. Gradually increase speed as conditions permit.
5. Engage Aerator: Lower the aerator using the single lever transport handle, allowing the coring knives to enter the ground.
6. Aerating Pattern: Aerate in the straightest lines possible, making overlapping passes to increase the plug pattern density.
7. Avoid Sharp Turns: Avoid extremely sharp turns with the plugger points engaged in the ground to prevent damage to the lawn and the aerator.
8. Crossing Obstacles: Do not cross over walks or drives without first raising the aerator to the transport position.
9. Slopes: On sloped lawns, always aerate in an up and down direction. Do not attempt to follow the contour of the ground.
10. Soil Condition: Do not attempt to aerate if the ground is too wet or muddy.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your aerator.

• Check Fasteners: Before each use, perform a visual check of the plug aerator for any loose bolts and nuts. Retighten any loose fasteners.
• Lubricate Wheels: Lubricate the wheels as needed to ensure smooth operation.
• Oil Spool Assemblies and Shaft: Oil the spool assemblies and shaft as needed to prevent rust and ensure free movement.
• Clean Knives: Clean dirt off the aerator knives after each use. Be careful of sharp edges when cleaning.
• Sharpen Plugs: Plugger points can be periodically sharpened with a small grinder to maintain good penetration. Remove the points to sharpen and follow the original angle and contour when grinding.
• Prevent Rust: Coat exposed metal with light oil to prevent rust.
• Storage: Clean the aerator and store it in a clean, dry area.
