Our Review

The Cobra RM40SPB Lawn Mower is a well designed petrol mower with a range of features and functions. It has a 40cm wide cutting width, making it ideally suited to lawns up to 600 square metres in size. In terms of height, the blade can be adjusted up and down (with a lever) between 25mm and 75mm, thereby letting you choose your lawn length. The mower is powered by a Briggs & Stratton 450e petrol engine which gives optimal torque, high efficiency and low emissions.

In terms of drive, the mower is self-propelled, meaning no pushing is required, only steering. This allows you to mow for longer without getting tired. We like how the mower is capable of cutting along edges (e.g. flower beds and walls). We also like the rear roller which produces a neat lawn striping effect. For longer uninterrupted mowing, a 50 litre fabric grass collection bag stores large amounts of grass. In fact, due to high air flow, the mower compacts grass inside of the bag to allow more to fit inside.

Specification

The features are as follows:

  • Cutting Performance - The Cobra RM40SPB Lawn Mower is designed for gardens up to 600 square metres in size. It has a large 40cm blade with an adjustable height that can be changed in six stages between 17mm and 75mm. This wide height range lets you enjoy extra-short summer grass or longer grass in the winter, for example. The height is set quickly with the on-board lever.
  • Petrol Engine - The mower has a Briggs & Stratton 450e petrol engine which offers a strong performance, including high torque and efficiency, as well as low emissions.
  • Self-Propelled - The mower drives itself forward thanks to its self-propulsion functionality. All you need to do is steer it. Self-propelled mowers cause much less fatigue when compared to standard push mowers.
  • Rear Roller - To produce the classic lawn striping effect, the mower has an on-board rear roller.
  • Edge Cutting - The mower can be used to cut along edges/borders such as against walls, fences, sheds, paths, flower beds, etc. The rear roller supports the mower when the front wheels are against edges.
  • Grass Bag - A 50 litre fabric grass bag holds a large amount of grass so that you can focus more on mowing. Fabric grass bags allow for increased air flow which helps with compaction and increases the amount of grass it can hold.
