Achieve a Professional Lawn Finish
The Cobra LR40 Garden Roller is an essential tool for any gardener aiming for a pristine, level lawn. Designed for exceptional coverage and ease of use, its 50cm (20″) roller is perfect for flattening uneven ground caused by molehills or frost heave. It’s particularly effective after seeding or laying new turf, as it presses the seeds or turf into the soil, ensuring better germination and root establishment. Using a roller is a classic technique for creating those desirable, striped lawn effects.
Versatile and User-Friendly Design
Engineered for practicality, the LR40’s drum can be filled with either water (providing a weight of up to 72kg) or sand (up to 120kg), allowing you to tailor the ground pressure to your specific task. An integrated, full-width scraper bar prevents soil and debris from compacting on the drum, ensuring a smooth and consistent finish. When the job is done, the roller can be easily emptied via the drain plug. For storage, the soft-grip handles fold down, making the unit incredibly compact and easy to store in a shed or garage.

Frequently Asked Questions
Frequently Asked Questions
What is the main purpose of the Cobra LR40 garden roller?
The Cobra LR40 is primarily used to level lawns and improve soil contact. It’s ideal for flattening uneven ground after winter, pressing down newly laid turf to encourage root growth, and ensuring new grass seed has firm contact with the soil for better germination. It can also be used to create classic lawn stripes.
Is it better to fill the LR40 roller with sand or water?
The choice between sand and water depends on the weight you require. Filling it with sand provides the maximum weight (up to 120kg) for compacting soil or levelling very uneven areas. Water provides a substantial but lesser weight (up to 72kg) and has the advantage of being easier to fill and empty via the drain plug.
How do I store the Cobra LR40 when not in use?
The Cobra LR40 is designed for easy storage. First, ensure the drum is completely empty of water or sand. The handles are designed to fold down over the drum, creating a very compact unit that can be easily stored upright or on its side in a garden shed or garage, taking up minimal space.
Does the scraper bar make a difference?
Yes, the full-width scraper bar is a crucial feature. As you roll, especially on damp soil, mud and debris can stick to the drum. The scraper bar continuously cleans the drum’s surface, preventing build-up and ensuring a smooth, even finish across your lawn without transferring clumps of soil to other areas.
