MULCH & SIDE DISCHARGE
The MX51S40VX cordless lawnmower from Cobra comes equipped with a mulch plug, allowing you to mulch your grass clippings back into the lawn for a healthier, greener finish. Mulching lawnmowers work by finely cutting and re-cutting the clippings, returning valuable nutrients to the soil. The MX51S40VX also offers the versatility of side discharge, using the side discharge chute to efficiently expel clippings to the side—ideal for tackling longer or more dense grass where collection isn’t practical.

FRONT GRASS COMBS
The new Cobra MX51S40VX is engineered for superior cutting performance and is equipped with innovative front-mounted grass combs. These specially designed combs work by gently lifting and aligning the grass blades before they reach the cutting deck, ensuring they are positioned perfectly for an even and precise trim. By guiding the grass into the path of the blades, this advanced feature not only enhances cutting efficiency but also contributes to a cleaner, neater finish.
