The premium Cobra MX46B petrol 4‐in‐1 lawnmower is powered by a Briggs & Stratton XAQ 500 Series engine. This mower is hand propelled and can either mulch, side / rear discharge or collect grass clippings. The Cobra MX46B petrol lawnmower has 7 adjustable cutting heights ranging from 25mm for a superb low finish, up to 75mm for tackling longer grass. All this is achieved by simply using the single height of cut adjustment lever. Depending on the height of your grass, you can easily and efficiently adjust the cutting height to suit.

The Cobra MX46B petrol lawnmower is equipped with a 60 litre fabric grass bag, ideal for collecting large amounts of grass clippings before the need for emptying. The grass bag on the Cobra MX46B is made from a robust, high quality fabric. This fabric enables a strong free flow of air which means that grass collection on this machine is even more compact and comprehensive.
  • Briggs & Stratton 500 series
    The 500 series engine provides the best‐in‐class performance in this category of engines. It incorporates the latest engine design technologies ensuring optimal torque and efficiency, resulting in lower emissions. The 500 Series powers Cobra lawnmowers for gardens up to 600 square meters.
  • Mulch plug
    The MX46B lawnmower from Cobra comes equipped with a mulch plug to enable you to mulch your grass clippings back into the lawn. Mulching lawnmowers recycle the grass by finely cutting and re‐cutting the clippings. As the clippings decompose, nutrients and fertilisers are returned to the soil meaning you can cut the grass and fertilise at the same time.
  • Side discharge
    If you don't want to collect your grass cuttings or your lawn has become overgrown, the MX46B comes equipped with a side discharge function. Simply lift the side blanking plate and insert the side discharge chute. The grass will now be discharged in neat lines to the side of where you are mowing.
  • Ergonomically positioned controls
    The Cobra MX46B petrol lawnmower has been designed to make cutting your grass a simple and effortless task. The ergonomically positioned controls not only make operator use more comfortable, but more importantly, make using Cobra lawnmowers safe and user friendly.
