The Cobra MM51B is a dedicated mulching lawn mower featuring a wide 51cm (20") steel deck with five stage height of cut adjustment. 

A push-propelled machine, the Cobra MM51B lawn mower is equipped with an easy starting 140cc Briggs & Stratton engine which delivers optimal torque and efficiency, resulting in lower emissions. The height of cut can be adjusted between 30mm to 75mm using the single lever height of cut adjustment lever located on the rear right hand wheel, so you can achieve a fine, close finish or tackle longer grass. 

This mulching mower effectively recycles the grass by finely cutting and recutting the clippings and distributing them evenly over the lawn surface. As the clippings decompose, valuable nutrients and fertilisers are returned to the soil to promote a healthy lawn. If the lawn has become overgrown, the Cobra MM51B lawn mower is also equipped with a side discharge function leaving the grass in neat lines to the side of where you are mowing.

You will be impressed by the quality and superior features of the Cobra MM51B mulching lawn mower, all at a very reasonable price and backed by a two year warranty.

Start mulching - the greener way to cut your lawn

This mower is equipped with a mulch plug to enable you to mulch your grass clippings back into the lawn.

Mulching lawn mowers recycle the grass by finely cutting and re-cutting the clippings. As the clippings decompose, nutrients and fertilisers are returned to the soil so you can cut the grass and fertilise as the same time.


Side discharge your grass

If you don't want to collect your grass clippings or your lawn has become overgrown, this mower comes equipped with a side discharge function. Simply lift the blanking plate and insert the side discharge chute. The grass will then be discharged in neat lines to the side of where you are mowing.


Single lever five stage height of cut adjustment

Five adjustable cutting heights range from 30mm for a superb low finish, up to 75mm for tackling longer grass.

All this is achieved by using the single height of cut adjustment lever located on the right hand rear wheel. Depending on the height of your grass, you can easily and efficiently adjust the cutting height to suit.


Two year warranty

Cobra petrol lawn mowers are backed by a two year manufacturer's warranty.
