Cobra GTRM400 Electric Lawnmower - Powerful Performance for Larger Lawns with a Professional Striped Finish

The Cobra GTRM400 Electric Lawnmower is the largest model in the GTRM electric rear roller range, combining impressive cutting performance with the classic striped lawn finish every gardener loves. Powered by a high-performance motor and featuring a generous 40cm cutting width, rear roller, and mulching capability, it's designed to make maintaining larger lawns easier and more efficient.

Built for versatility, comfort, and exceptional results, the GTRM400 delivers a neat, consistent cut while helping you achieve a beautifully presented lawn throughout the growing season.

  • Powerful electric motor
  • 40cm (16") cutting width
  • Rear roller for traditional lawn stripes
  • 7-stage height adjustment from 25mm to 75mm

Wider Cutting for Faster Mowing
With its generous 40cm cutting deck, the GTRM400 allows you to cover more ground with every pass, helping you complete mowing tasks more quickly. Despite its larger size, the mower remains easy to manoeuvre around flower beds, pathways, borders, and other garden features.

Create Beautiful Lawn Stripes
The integrated rear roller produces the traditional striped finish associated with professionally maintained lawns. Combined with Cobra's precise cutting performance, the GTRM400 helps you achieve a neat, attractive appearance every time you mow.

Mulch for a Healthier Lawn
Supplied with a dedicated mulch plug, the GTRM400 can finely shred grass clippings and return them to the lawn. This natural process recycles valuable nutrients and moisture back into the soil, encouraging healthier grass growth while reducing garden waste and the need for collection.

Cleaner Lawn Edges
Integrated front and side grass combs guide grass growing close to walls, fences, pathways, and borders directly into the blade's cutting path. This helps achieve a cleaner finish around lawn edges while reducing the need for additional trimming.

Flexible Cutting Heights
The convenient push-button height adjustment system offers seven cutting positions ranging from 25mm to 75mm, allowing you to adapt quickly to changing lawn conditions throughout the season and achieve the perfect finish every time.

For gardeners looking for maximum cutting capacity within the Cobra electric rear roller range, the GTRM400 offers the perfect combination of power, mowing efficiency, mulching capability, and classic striped lawn performance.
