Cobra MM51B 51cm Petrol Mulching Lawn Mower


The new Cobra MM51B dedicated mulching mower is powered by the renowned Briggs and Stratton 500E series engine and is hand propelled for complete user freedom. It is idea for larger gardens up to 600 square meters.

The 500 Series engine provides the best-in-class performance in this category of engines. It incorporates the latest engine technologies ensuring optimal torque and efficiency, resulting in lower emissions.

Its wide 51cm (20") cutting deck can be converted to either mulch mode or side discharge. It is ideal for cutting larger areas of lawn where there is no need to collect the grass cuttings.

The mulch mode ensures that the grass cuttings stay in the deck for longer and so are cut into finer pieces. The cuttings then fall onto the grass, and as they decompose the nutrients and fertilisers are returned to the soil. Mulching also improves the drought resistance of your grass by reducing evaporation from the soil.

If your grass is overgrown and you do not want to mulch then the deck can be converted to side discharge simply by inserting the side discharge chute. The grass cuttings will then be discharged in a neat line to the side of where you are cutting.

The mower has 5 adjustable cutting heights ranging from 30mm up to 75mm for tackling longer grass. The cutting height can be adjusted quickly and easily using the single height adjustment lever.

IMPORTANT: Please ensure you fill the engine with the FREE oil provided and check its level with the dip stick before use
