Cobra S3840V Review

The Cobra S3840V Cordless Lawn Scarifier is a dual purpose machine which can be used as both a scarifier and an aerator. It successfully removes dead grass/vegetation, moss and debris from your lawn, and makes your lawn's soil less dense to allow nutrients to get through to the roots. It's suitable for small/medium sized lawns, and has a 38cm operating width.

The scarifier has an adjustable height which can be set in five stages between -10mm and +5mm with a single lever. We particularly like the cordless nature of the unit. As such, it can be taken and used anywhere. It utilises a long lasting 40V 5000mAh Samsung battery. There's also a power level indicator on the machine's handle. We like the fact that the handle is height-adjustable, letting you use the machine in a comfortable manner.

Specification

We now look at the features:

• 2-in-1 Functionality - The Cobra S3840V is a 2-in-1 lawn scarifier and aerator. So not only can it remove dead grass, moss, thatch and other similar debris from your lawn, but it also reduces soil compaction and allows nutrients to get down to the roots. It's recommended to scarify/aerate your lawn early in the spring and late in the autumn. Both scarifier and aerator drums are included.
• Performance - The unit is suitable for small to medium sized lawns given its 38cm operating width. It has a height dial so that you can select 5 heights (depths) between -10mm and 5mm, letting you adjust easily as needed.
• Cordless - The unit is cordless. It's instead powered by a 40V 5000mAh Samsung battery which provides it with a long run time. Note that a battery and charger are included. Cordless scarifiers can be taken anywhere, including to locations not near power sockets. Note that the handle has a power remaining indicator.
• Grass Box - The Cobra S3840V collects grass (and other debris) in its 45 litre collection box. A large box such as this requires emptying less often than a smaller one would, therefore letting you focus more on scarifying and less on emptying.
• Handle - The unit has height-adjustable handles to make scarifying more comfortable. It also has foldable handles to allow for compact storage.

Summary

Overall, the Cobra S3840V Cordless Lawn Scarifier is a high performance 2-in-1 scarifier and aerator with a number of features designed for practicality and comfort. It easily removes dead grass, dead vegetation and other debris from lawns, and also reduces soil compaction which lets nutrients get deeper down. We particularly like the unit's adjustable depth, large grass box, and highly manoeuvrable cordless design. We rate the Cobra S3840V Cordless Lawn Scarifier 4 out of 5 stars.
