Every Cobra lawnmower has been expertly designed in the U.K to cater specifically for the changing conditions of the British lawn.

With exceptional performance and style, the Cobra M40B 16" petrol lawnmower is powered by a Briggs & Stratton 450E Series engine and is hand propelled for complete user freedom.

The Briggs Stratton 450 Series engine provides the best-in-class performance for this category of engines. It incorporates the latest engine design technologies ensuring optimal torque and efficiency, resulting in lower emissions. The 450 Series powers Cobra mowers for gardens up to 600 sq/m & features a recoil start.

With a cutting width of 40cm / 16", the Cobra M40B lawnmower also has 10 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.

In addition to its robust, high quality steel deck & rotary cutting blade, the Cobra M40B petrol lawnmower is equipped with a 50ltr fabric grass bag, ideal for collecting large amounts of grass clippings before the need for emptying. The grass bag is made from a robust, high quality fabric & enables a strong free flow of air meaning that grass collection on this machine is even more compact and comprehensive.

The Cobra M40B also features a folding handlebar making it easy to put away after use, saving precious space & ensuring safe, compact storage.

This Cobra machine is shipped without oil in the machine. Within the packaging there will be a sealed bottle of oil that must be decanted into your unit before the machine is started. Further information can be found in the operators manual. Please read this before starting. Failure to fill your machine with oil will result in a catastrophic failure that will not be covered under warranty.

New E10 Fuel & your Cobra

As you may be aware the current grade of petrol has recently changed in the UK to E10. E10 has been used in mainland Europe for some time & there have not been any major problems reported with its use in lawn mowers & garden tools.

We would however recommend the following to prolong the life of your Cobra:

  • At the end of the season, or if you're not going to use your Cobra for a long period of time, drain or run the fuel tank dry
  • If you're using E10 use Briggs & Stratton Fuel Fit additive
  • You can always opt for Premium Unleaded fuel

Good, reliable machine
I opted for this version with the larger engine as my grass is very thick. It copies with it brilliantly, starts very easily and runs without any issues. The grass bag size is good and will only clog if you try to cut too much height at once. Cut longer grass in a few steps and it's absolutely fine.
