Self-Propelled Drive and Brushless Motor
The machine features a self-propelled drive system that assists with forward movement, lowering physical strain when managing inclined surfaces or longer grass. Power is delivered by an efficient brushless motor that minimizes internal friction and wear over time. This configuration optimizes power delivery from the 40V Max+ battery system, ensuring a consistent cutting performance while maintaining lower noise levels and requiring less upkeep than a traditional petrol engine.
Rear Roller and Lawn Striping
An integrated full-width rear roller flattens the grass blades behind the cutting deck, allowing operators to achieve a structured, traditional striped lawn finish. In addition to aesthetic results, the rear roller design increases overall machine stability during operation. This configuration allows for precise cutting right up to the perimeter of the lawn, preventing the mower from tipping over when working along the edges of flowerbeds, pathways, and garden borders.
Steel Deck and Variable Cutting Heights
Built with a durable steel deck, the mower chassis is engineered to withstand impact from hidden garden debris while maintaining structural rigidity. The 43cm (17 inch) cutting path balances rapid coverage with manoeuvrability around tighter garden obstacles. To accommodate seasonal growth variations, a central lever adjusts the cutting height through six specific stages from a low 17mm finish up to a maximum height of 75mm.
Direct Collection and Storage
The mower utilizes a direct collection system that forces clippings straight from the blade area into a 50-litre grass bag. This bag incorporates a built-in full indicator mechanism, which lets the operator know exactly when to empty the collector to prevent chute blockages. For transport and storage between uses, the handles are fitted with integrated cam locks, enabling the frame to fold down swiftly for a more compact footprint in sheds or garages.
Interchangeable Dual-Battery Platform
This model is supplied with two 40V 4Ah Li-ion Max+ batteries and a quick charger. The Max+ system features built-in tool-recognition technology, allowing the battery to communicate with the mower and automatically adjust output for peak efficiency. These batteries are fully interchangeable with all other garden machinery within the Cobra 40VX range, including grass trimmers, leaf blowers, and chainsaws, though they are not compatible with standard Cobra 40V battery platforms.
