The Cobra MX4340VX is a versatile and lightweight 17” cordless lawn mower designed for the modern medium-sized garden. Powered by the 40V MAX+ lithium-ion system, it provides a quiet, emission-free alternative to petrol mowers while delivering the performance needed to maintain a pristine lawn.
Constructed with a 43cm (17”) high-grade polymer deck, the MX4340VX is naturally rust-resistant and exceptionally maneuverable. Weighing only 15.5kg, it is easy to push and navigate around garden furniture, flower beds, and tight corners, making it an ideal choice for users who prioritize ease of use.
The MX4340VX offers two distinct ways to handle your grass clippings:
Collection: Includes a 50-litre grass bag made of high-quality breathable fabric. The integrated full-bag indicator lets you know exactly when it’s time to empty, reducing unnecessary stops.
Mulching: A mulch plug is included as standard. This allows you to finely shred clippings and return them to the lawn, acting as a natural fertilizer to promote a greener, healthier garden.
5-Stage Height Adjustment: A single central lever allows you to quickly change the cutting height from 25mm for a formal finish to 75mm for longer spring growth.
Edge-to-Edge Cutting: The deck is designed in line with the wheels and features front and side grass combs, ensuring a tidy cut right up to the edges of borders and paths.
Infinite Handle Adjustment: The handles feature soft-grip padding and can be adjusted to any angle to suit the user's height. They also fold down completely for compact storage in small sheds.
Power Source: 40V 4.0Ah Li-ion MAX+ Battery (Included)
Charger: Standard MAX+ Charger (Included)
Motor: High-efficiency Brushless Motor
Cutting Width: 43cm (17")
Cutting Heights: 5 Stages (25mm – 75mm)
Deck Material: Rust-proof Polymer
Collector Capacity: 50 Litres
Weight: 15.5kg (excluding battery)
Warranty: 2-Year Domestic Warranty
Cobra 40V MAX+ Ecosystem: The included battery is fully interchangeable with Cobra’s cordless hedge trimmers, chainsaws, and blowers.
Brushless Motor Technology: Delivers more torque and a longer motor life with significantly less noise than brushed alternatives.
Lightweight Durability: The polymer deck is tough enough for regular use while remaining easy to lift and transport.
Zero Emissions: Environmentally friendly mowing with no petrol mixing, pull-cords, or toxic fumes.
Compact Footprint: Foldable handles and a removable grass bag make it easy to store in height-restricted areas.
