Equipped with Cobra's own 173cc four-stroke OHV engine, the M51SPC is a quality, feature-packed 4-in-1 self-propelled rotary lawn mower at a fantastic price. 

The Cobra M51SPC is equipped with a 51cm (20")  robust steel cutter deck. The cutting height can be centrally adjusted to suit conditions, through 10 adjustable settings ranging from 25mm for a superb low finish, up to 75mm for tackling long grass. Grass clippings are collected in a durable fabric grass bag which has a generous 60 litre capacity.

With the versatile Cobra M51SPC you have even more mowing options. If you don't want to collect your grass cuttings or your lawn has become overgrown, the lawn mower is equipped with a side discharge function. In addition, the mulch plug allows you to cut your lawn the greener way. This mulching function recycles the grass by finely cutting and re-cutting the clippings, dispersing them evenly back into the lawn. As they decompose, nutrients and fertilisers are returned to the soil so you can mow and fertilise the grass at the same time.

The comfort handles and self-propelled drive system ensure ease of use when tackling larger mowing jobs. Quick release folding handles allow easy transport and compact storage.

Combining power, quality, style and reliability, the Cobra M51SPC self-propelled petrol lawn mower is backed by a two year manufacturer's warranty for homeowner use.

Cobra DG600 OHV engine, expertly powering Cobra lawn mowers

The Cobra DG600 173cc engine offers a quiet, yet powerful combination for a variety of demanding applications. It incorporates the latest engine design technologies ensuring optimal torque and efficiency. 


Start mulching - the greener way to cut your lawn

Equipped with a mulch plug to mulch your grass clippings back to the lawn. Mulching lawn mowers recycle the grass by finely cutting and re-cutting the clippings. As they decompose, nutrients and fertilisers are returned to the soil. Mulching in this way also saves time as there is no grass collector to empty.


Side discharge your grass with Cobra

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


Self-drive system

The self-propelled drive system gives added comfort and ease of operator use. This takes the effort out of pushing your mower, meaning you can maintain your lawn and not feel exhausted when cutting is complete! This feature is particularly useful when there are slopes as well as thick grass.


Single lever 10 stage height of cut adjustment

Ten adjustable cutting heights range from 25mm for a superb low finish, up to 75mm for tackling long grass. Adjustment is via the single height of cut adjustment lever.


Large capacity grass bag for increase collection

A capacious 60 litre fabric grass bag allows collection of large amounts of grass clippings before the need to empty.

The grass bag is made from a robust, high quality fabric. This fabric enables a strong free flow of air so that grass collection on this machine is even more compact and comprehensive.



Two year warranty

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