Traditional Striped Lawn Finish
The integrated full-width rear roller allows operators to achieve classic lawn stripes while mowing. By flattening the grass blades in the direction of travel, the roller creates the contrasting light and dark bands characteristic of traditional British lawns. Additionally, the roller layout stabilizes the mower when cutting right up to the edges of flowerbeds and garden borders, preventing the wheels from dropping into soil or damaging turf.
Battery and Brushless Motor Efficiency
This lawnmower utilizes a 40V Max+ lithium-ion battery system paired with a brushless motor. The Max+ system automatically detects the specific tool in use to optimize power output and run times. The brushless motor design reduces friction and wear compared to brushed alternatives, extending the service life of the machine and maximizing battery efficiency during operation. A quick charger is included to minimize downtime between mowing sessions.
Steel Deck and Cutting Adaptability
Built with a robust steel deck, the chassis provides durability and resistance against impact from stones or debris. The 43cm (17") cutting width provides a balance between rapid ground coverage and precise control around garden obstacles. For varying seasonal conditions, the cutting height can be adjusted through six distinct stages from 17mm for a low finish up to 75mm for longer, overgrown grass.
Collection and Storage Features
The mower uses a direct collection system that funnels clippings straight into a 50-litre grass bag. An integrated full indicator alerts the user when the bag reaches capacity, reducing the risk of clogging the discharge chute. For transport and storage, the handles are fitted with cam locks, allowing them to fold down quickly to save floor space in sheds or garages.
Interchangeable Range Capability
The supplied 40V MAX PLUS battery is part of a wider interchangeable system. This single power source can be moved between various compatible garden machinery in the Cobra 40VX range, including grass trimmers, leaf blowers, chainsaws, and multi-tools. Please note this specific Max+ battery is distinct from, and incompatible with, standard Cobra 40V battery platforms.
