Lawnmower Universal Chain 350MM

The 350mm Universal Lawnmower Chain (commonly referred to as a "slasher chain") is a high-durability cutting attachment engineered for heavy-duty vegetation management. Designed as a robust alternative to standard steel blades, this chain system is specifically calibrated for rotary lawnmowers used in rugged terrains, high-density brush, and areas where hidden obstacles (such as rocks, stumps, or metal debris) would typically shatter or dull a conventional solid blade.

Mechanical Engineering and Dynamics

• Centrifugal Cutting Force: The system utilizes high-tensile steel chain links that extend fully via centrifugal force once the mower engine reaches operational RPM. This creates a high-velocity cutting edge capable of mulching thick grass and light woody stalks with ease.
• Impact-Absorbent "Swing-Back" Logic: Unlike a rigid steel blade that transfers the full force of an impact to the engine's crankshaft, the chain links are flexible. Upon striking a solid object, the chain simply deflects or "coils" momentarily, significantly reducing the risk of a bent crank or sheared woodruff key.
• Heat-Treated Alloy Steel: The individual links are manufactured from hardened alloy steel, providing superior abrasion resistance. This ensures the cutting "edge" of the links remains effective even when operating in sandy or abrasive soil conditions.
• Universal Center-Hole Configuration: The mounting boss is engineered with a universal aperture (typically 20mm with reducers) to fit a wide range of petrol and heavy-duty electric lawnmowers.

Operational Specifications

• 350mm (14") Effective Cutting Swath: The length is optimized for standard medium-sized mowers, providing a balanced rotational mass that maintains engine RPM without overloading the drive system.
• Aerodynamic "Low-Drag" Profile: The link geometry is designed to minimize air resistance, allowing the motor to reach peak cutting speed quickly while reducing fuel consumption compared to heavy, solid "bar" blades.
• Multi-Surface Versatility: While effective on standard lawns, this system excels in "veld" cutting, firebreak maintenance, and clearing overgrown vacant stands where the condition of the ground is unknown.

Installation and Safety Maintenance

• Balanced Rotational Mass: The chains are precision-matched in weight to ensure the mower remains balanced. An unbalanced cutting head can cause severe vibration, leading to premature bearing failure and operator fatigue.
• Secure Bolt-On Assembly: The unit features high-grade locking hardware to ensure the chains remain seated within the carrier disc during high-speed rotation.
• Wear Inspection: Because the chain is a high-friction component, it is designed for periodic inspection. Links should be checked for "thinning" at the contact points and replaced once the structural integrity of the link is compromised.

Primary Applications

• Agricultural and Plot Maintenance: Ideal for clearing long grass and weeds around fences, kraals, and outbuildings where rocks and debris are common.
• Industrial Site Clearing: A cost-effective solution for maintaining road verges, construction site perimeters, and municipal parklands.
• Heavy-Duty Domestic Gardening: Provides a "worry-free" mowing experience for large gardens with uneven terrain or hidden tree roots.

Designed for professional-grade durability, the 350mm Universal Lawnmower Chain is a foundational tool for any high-volume maintenance inventory. Its combination of mechanical flexibility and aggressive cutting power provides a dependable and low-maintenance alternative to traditional mower blades in demanding African environments.
