Self propelled, B&S 675IS 163cc engine, 51cm Aluminium Deck, 7 height options, 60L bag

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 MX515SPBI petrol 4-in-1 lawnmower is powered by a B&S 675IS Series InStart engine and can either mulch, side / rear discharge or collect grass. This Cobra mower is self propelled with a reliable 5 speed gearbox.

The 675IS InStart engine from Briggs & Stratton delivers the next generation in easy starting. Ingenious integration of engine and battery gives you cutting power at a touch. Proven Lithium-ion battery technology ensures simple instant starting over-and-over again without constant recharging. Push-button is the easiest starting ever and InStart technology eliminates the need for the traditional recoil starting system. The InStart battery can be quickly charged from flat so you don't have to wait too long until your mower is ready to go! More than 50 starts from a fully charged battery.

The Cobra MX515SPBI petrol lawn mower comes equipped with a self propelled, 5 speed drive system providing speeds of 3km/h - 4.2km/h depending on user preference for added comfort and ease of operator use. The self propelled system takes all the effort out of pushing your lawnmower, meaning you can maintain your lawn with ease, even when mowing thick grass or cutting on an incline.

With a cutting width of 51cm / 20", the Cobra MX515SPBI also 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 MX515SPBI mower features a hard wearing, cast aluminium deck which is the popular choice for both professional and domestic users alike. The aluminium deck has many other benefits as well as its durability, such as being less susceptible to corrosion, easy to clean and having a longer working life.

In addition to its aluminium deck & rotary blade the Cobra MX515SPBI is equipped with a 60ltr 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 MX515SPBI lawnmower from Cobra comes equipped with a mulch plug attachement 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.

If you don't want to collect your grass cuttings or your lawn has become overgrown, the MX515SPBI 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.

The Cobra MX515SPBI 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
