Equipped with a robust polymer deck, the mower has seven adjustable cutting heights ranging from 20mm to 75mm. As the roller between the rear wheels supports the lawn mower, the Cobra GTRM38 gives you the ability to mow right up to the edges of flower beds and borders.

The 40 litre fabric grass bag is ideal for collecting large amounts of grass clippings before the need to empty. To make life even easier, Cobra has equipped the GTRM38 electric lawn mower with a grass bag full indicator system.

For greater flexibility and the greener way to cut your lawn, the Cobra GTRM38 lawn mower is equipped with a mulch plug to enable you to recycle the grass by mulching your grass clippings back into the lawn. As the clippings decompose, valuable nutrients and fertilisers are returned to the soil to promote a healthy lawn. Mulching also saves time as there is no need to stop to empty the grass collector.

Soft grip handlebar controls take the effort out of mowing your lawn. The handles have quick release levers and can be set to any angle of use, and are fully folding for compact storage.

Lightweight at 14kg, the Cobra GTRM38 is ideal for the smaller lawn and is packed with innovative features to help you create the perfect garden with the minimum of effort.

It arrived in good time in excellent condition. It was easy to assemble the handle though the illustrations could have been clearer. Wow! What a difference in our lawn... We had the last mower for 12 years and had not realised how good a cut can be. We now vie with each other to cut the grass!!

Lovely mower with a very good easy to adjust height trimming mechanism. Grass mulcher included with the mower. It is a little on the heavy side for carrying up steps but gives an excellent result. Very happy with mine.

I did plenty of research before buying and looked at many different types in the shops but wasn't pleased with the quality of the ones that I saw. I bought the Cobra on spec and I am very pleased. It's excellent quality for the price and I am very pleased with it. It is fairly small and light enough to pick up with one hand but still copes well with my medium sized lawn, even when the grass has been left for some time :). The roller, and the stripes it leaves, is an added bonus. If you are looking for a good value, light weight mower then I recommend this Cobra.

found this model heavier than what I normally use but once the right setting was found it was quite easy to push . good sturdy mower easy to assemble good value compared to my normal mowers downside the grassbox has no holding points at the bottom so when emptying grass spills out
