Description

Why buy the Cobra MX46SPE 18″ Electric Lawnmower?

  • Powerful 1800W mains electric motor
  • Self-propelled drive system for effortless mowing
  • Versatile 3-in-1 function: collect, mulch, or side discharge
  • Generous 18″ (46cm) cutting width for efficient coverage
  • Large 60-litre grass bag with a handy full indicator
  • Single lever 7-stage height adjustment (25-75mm)

Powerful and Convenient Electric Mowing

The Cobra MX46SPE is a robust and feature-rich electric lawnmower designed for homeowners seeking power and convenience without the maintenance of a petrol engine. At its heart is a powerful 1800W motor, providing ample torque to handle tough cutting conditions. The generous 15-metre power cable offers substantial reach for most small to medium-sized gardens, ensuring consistent performance throughout your mow.

Effortless Operation with Self-Propelled Drive

Mowing is made significantly easier thanks to the mower’s self-propelled drive system. Engaging the drive lever propels the mower forward at a comfortable walking speed of 3.3km/h, taking the strain out of pushing, especially on sloped or uneven ground. This feature is particularly beneficial for those with larger lawns, reducing operator fatigue and making the task of lawn maintenance much more enjoyable.

Ultimate Versatility with a 3-in-1 Cutting System

The MX46SPE offers exceptional flexibility with its 3-in-1 cutting system. You can choose the best option for your lawn’s condition:

  • Collection: The large 60-litre grass bag efficiently collects clippings, leaving a neat and tidy finish. A convenient indicator flap shows when the bag is full and needs emptying.
  • Mulching: By inserting the mulch plug, the mower finely shreds the grass clippings and returns them to the lawn surface. This process acts as a natural fertiliser, nourishing the grass and promoting healthier growth.
  • Side Discharge: For longer, rougher grass or areas where collection isn’t necessary, the side discharge chute quickly and efficiently ejects clippings away from the cutting path.

Durable Design and User-Friendly Features

Built with a durable steel deck, the Cobra MX46SPE is designed to withstand the rigours of regular use. The 18″ (46cm) cutting width allows for efficient coverage, reducing the number of passes required. Adjusting the cutting height is simple with a single lever that offers seven distinct stages, from a low 25mm to a high 75mm cut. For easy storage and transport, the handles feature cam locks, allowing them to be folded down quickly without the need for tools.

Frequently Asked Questions

Who is the Cobra MX46SPE lawnmower best suited for?

This mower is ideal for homeowners with small to medium-sized lawns who want the power and convenience of an electric mower combined with the ease of a self-propelled drive system. It’s perfect for those who find pushing a mower strenuous or have sloped or uneven terrain to manage.

What are the benefits of the 3-in-1 cutting system?

The 3-in-1 system offers great versatility. Use the 60L collector for a clean, tidy finish. Switch to the mulching function to finely chop clippings and return them to the lawn as a natural fertiliser. For overgrown or rough areas, the side discharge option allows for quick cutting without the need to stop and empty a bag.

How long is the power cable on the MX46SPE?

The Cobra MX46SPE comes with a 15-metre power cable. For safety, it is always recommended to use a residual current device (RCD) with mains-powered outdoor equipment. If your garden is larger than the cable’s reach, a suitable outdoor extension lead may be required.

Is a steel deck better than a plastic one?

A steel deck, like the one on the MX46SPE, offers superior durability and rigidity compared to plastic alternatives. It is more resistant to impacts from stones or debris and provides a stable foundation for the cutting system, contributing to a better quality cut and a longer machine life.
