2. Product Components
Familiarize yourself with the main components of your Goplus Lawn Roller:
- Roller Drum: The main cylinder that can be filled with water or sand.
- Gripping Handle: For manual pushing or pulling. Detachable for towing.
- Tow Bar: Connects the roller to a tractor or ATV for towing.
- Scraper Bar: Prevents debris and soil accumulation on the drum.
- Drain Plug: For filling and emptying the roller drum.
- Frame: Heavy-duty metal frame supporting the drum and handle/tow bar.

3. Setup and Assembly
The Goplus Lawn Roller requires assembly. Follow these steps carefully:
- Unpack Components: Carefully remove all parts from the packaging. Verify that all components listed in the packing list are present and undamaged.
- Attach Frame to Drum: Secure the main frame assembly to the roller drum using the provided bolts and nuts. Ensure the scraper bar is positioned correctly, facing the drum to prevent soil buildup.
- Assemble Handle/Tow Bar: Connect the handle sections. Depending on your intended use (push or tow), attach the gripping handle or the tow bar to the main frame. Ensure all pins and latches are securely fastened.
- Final Checks: Double-check all connections and fasteners to ensure they are tight and secure before proceeding to fill the drum.
4. Operating Instructions
Filling the Roller Drum
The roller's weight can be adjusted by filling the drum with water or sand.
- Locate the removable drain plug on the side of the roller drum.
- Remove the drain plug.
- Fill the drum with water or dry sand. The maximum capacity is 30 gallons (113 liters). Adjust the fill level based on the desired compaction and terrain.
- Securely re-insert the drain plug to prevent leakage. Ensure it forms a tight seal.

Push Operation
For manual operation, ensure the gripping handle is securely attached and the tow bar is folded or removed if not in use. Push the roller across the lawn in overlapping passes to achieve even compaction. The round corners of the drum are designed to ensure smooth turns without damaging the lawn.
Tow-Behind Operation
For larger areas, the roller can be towed behind a tractor or ATV.
- Detach the gripping handle and fix it to the tow bottom as indicated in the assembly instructions.
- Connect the tow bar to your tractor or ATV using the appropriate hitch pin and latch. Ensure the connection is secure.
- Operate the tractor or ATV at a slow, steady speed. Avoid sudden turns or excessive speed, especially when the roller is full.
- Make overlapping passes to ensure uniform rolling of the lawn.

5. Maintenance
Cleaning
After each use, clean the roller drum and scraper bar to remove any accumulated soil, grass, or debris. The scraper bar is designed to minimize buildup during operation, but manual cleaning may still be necessary.
Storage
When not in use, especially during colder months, empty the roller drum of water to prevent freezing and potential damage to the drum. The roller can be stored upright by leaning it against a wall or hanging it to save space, thanks to its gripping handle design.

Inspections
Periodically inspect all bolts, nuts, and connections for tightness. Check the roller drum for any signs of damage or leaks. Ensure the powder-coated finish is intact to maintain rust resistance.
6. Troubleshooting
- Roller not compacting effectively: Ensure the drum is adequately filled with water or sand. Increase the fill level for more weight and better compaction.
- Difficulty turning or damaging lawn during turns: Ensure the drum is not overfilled, which can make it too heavy. Make wider, smoother turns. The round edges are designed to minimize damage, but sharp turns should be avoided.
- Water leakage from drain plug: Ensure the drain plug is fully and securely inserted. Check the plug for any damage or wear and replace if necessary.
- Excessive debris buildup on drum: Clean the scraper bar regularly. Ensure the scraper bar is properly adjusted and positioned close to the drum surface.
- Unstable operation when towing: Verify that the tow bar is securely attached to both the roller and the towing vehicle. Ensure the towing vehicle is operated at a consistent, slow speed.
