Twin Battery Efficiency and Power Optimization
This lawnmower utilizes the Cobra twin 40V Max+ lithium-ion battery system to deliver 80V of performance. The internal system recognizes the tool in use to optimize energy output for longer run times and higher efficiency. Power is supplied by two 40V 4Ah Li-ion Max+ batteries, which are charged via two included Max+ quick chargers, and the system is designed exclusively for the Cobra 40VX product line.
Full-Width Rear Roller for Lawn Striping
The integrated full-width rear roller allows the operator to achieve a traditional striped finish across the grass. In addition to aesthetic patterning, the rear roller provides physical stability when operating the machinery. This setup allows for precise cutting right up to the edge of garden borders, flowerbeds, and pathways without the risk of the deck dropping.
Wide Steel Deck and Self-Propelled Drive
A robust 51cm (20 inch) steel cutting deck is paired with a brushless motor to handle larger grassed areas efficiently. To minimize operator fatigue, the machine features a self-propelled drive system that moves the 20-inch wide mower forward independently. Ergonomically placed controls allow the user to manage the pace and direction easily, even when navigating uneven ground.
Single Lever Height and Collection Systems
The height of cut can be altered across 6 distinct stages ranging from a low 17mm finish up to 75mm for longer growth. This is controlled by a single lever located next to the rear roller. Clippings are collected through a direct system into a high-capacity 70-litre grass bag, a volume intended to decrease the frequency of stopping to empty the collector during larger jobs.
Storage and Multi-Tool Compatibility
The lawnmower handles feature a cam-lock mechanism, enabling them to fold down completely to reduce the storage footprint in garages or garden sheds. The two included high-performance 40V MAX PLUS lithium-ion batteries are engineered for seamless compatibility across the entire Cobra 40VX cordless garden tool range, which includes strimmers, blowers, chainsaws, and multi-tools.
