Lawn mower grass head kit includes aluminium cylinder trimmer head with four 27.5cm light yellow square line grass ropes, wrench and gasket accessories for replacement or repair of trimmer line systems.
Luzhu Aluminium Lawn Mower Grass Head Replacement Kit with 27.5cm Line

When your lawn mower's trimmer head becomes worn, damaged, or the line repeatedly breaks, finding a compatible and complete replacement is a common gardening task. This Luzhu accessory kit is designed to address that need directly, offering a packaged solution that includes the core cutting mechanism, the consumable line, and the tools required for installation. The primary component is a silver aluminium cylinder grass head, which houses the trimmer line, accompanied by four lengths of pre-cut, light yellow, square-profile grass rope. With a total kit weight of 180g and including a wrench and gasket, this product provides the essential parts to restore your mower's edge-trimming function, assuming compatibility with your specific machine model.
Features and Construction

The kit's value lies in its completeness and the specified materials used in its construction. Rather than sourcing a head and line separately, this package delivers all items needed for a typical replacement job in one box, centred around a durable aluminium housing.
Material and Build
The central grass head is fabricated from aluminium, a metal chosen for its favourable strength-to-weight ratio. This construction results in a rigid housing for the trimmer line that adds minimal weight to the mower's assembly, which can help maintain balance and reduce operator fatigue during use. The silver finish is the standard colour for this material. The accompanying grass ropes are made from a flexible, wear-resistant plastic, cut into a square cross-section, which is a common profile for effective grass cutting. The square shape can provide a sharper cutting edge compared to round line as it rotates.
Size and Practical Fit
Physical dimensions are key for compatibility. The aluminium cylinder head itself has a compact profile, measuring 4.5 centimetres in width and 5 centimetres in height. The four supplied lines are each precisely 27.5cm long, a ready-to-use length that avoids waste and the need for manual cutting prior to first use. The total weight of the single product is 180 grams, confirming its lightweight nature. It is crucial to verify that these dimensions correspond with the mounting mechanism and line capacity of your specific lawn mower model before purchase, as fit is not universal across all brands.
Uses and Placement

This product serves a defined functional role within garden maintenance, specifically for powered lawn care equipment. Its use is tied directly to the operation of line trimmer systems, whether as part of a dedicated strimmer or a trimmer attachment on a lawn mower.
Event or Professional Use
For gardeners or landscaping professionals, having a ready supply of replacement heads and line is part of routine equipment maintenance. This kit can function as a convenient spare part to minimise downtime. Keeping a replacement head pre-loaded with fresh line allows for a quick swap when the installed line is spent or the head mechanism fails, enabling you to continue a landscaping job without a lengthy trip to a supplier. The inclusion of the wrench specifically aids in this faster field replacement process.
Everyday Home Use
For the home user, this kit simplifies the occasional need to replace a worn-out trimmer head. Instead of diagnosing whether the issue is the head, the line, or a fitting, this complete set provides a holistic replacement. The pre-cut lines eliminate the guesswork and potential inaccuracy of cutting your own lengths from a coil. After installing the kit, the old head can often be discarded, providing a fresh start with new components that should operate smoothly for the next season of garden tidying, edging lawns, and trimming around obstacles.
Benefits and Buying Value

The advantages of this product stem from its packaged nature, material choice, and the clarity of its included components. It offers a practical, no-fuss approach to a common maintenance task.
Reuse and Low Maintenance
The aluminium head is designed as a reusable component. Once installed, only the plastic grass ropes are consumable. When the four supplied lines are used, they can typically be replaced with new lines of the same square profile and approximate length, extending the life of the head unit itself. Maintenance is minimal; primarily ensuring the head is free from tangled grass and debris which could impede rotation. The aluminium material is naturally corrosion-resistant, which is beneficial for equipment often stored in sheds or garages where humidity may fluctuate.
Why Choose This Product
Choosing this Luzhu kit is a decision based on convenience and specification matching. The primary reason is the inclusion of everything needed: the head, the line, and the fitting tool. This removes the complexity of buying separate, potentially mismatched items. The concrete specifications – the aluminium material, the 27.5cm line length, the square line profile, and the 4.5cm x 5cm head size – allow for an informed compatibility check against your existing equipment. For users whose mowers match these specs, it represents a direct, time-saving solution to refurbish their trimmer's cutting capability.
