Cobra 38cm 40V MAX+ Lithium-Ion Push Cordless Lawn Mower Kit - MX3840VX

Cobra MX3840VX 38cm 40V MAX+ Lithium-Ion Push Cordless Lawn Mower (with 4Ah Battery & Standard Charger)

Ideal for small to medium lawns, the Cobra MX3840VX is a lightweight, hand-propelled cordless lawn mower powered by the advanced Cobra 40V MAX+ lithium-ion battery system. With a 38cm cutting width, easy single-lever height adjustment and a compact, durable deck, it delivers a clean, precise finish without the noise, fumes or hassle of petrol.

Five cutting heights from 25mm to 75mm let you switch easily between a close, manicured finish and tackling longer grass. Grass clippings are collected into a 40 litre fabric grass bag with hard lid and bag full indicator, or you can fit the included mulch plug to finely chop clippings and return them to the lawn, recycling nutrients back into the soil and reducing the need for chemical fertilisers.

Weighing just 12.7kg and built around a strong ABS polymer deck, the MX3840VX is easy to handle and highly manoeuvrable. The deck is designed in-line with both front and rear wheels so you can cut right up to walls, borders and edging, while front and side grass combs lift the grass into the blade for a cleaner, more efficient cut. Soft-grip folding handles with infinite angle adjustment ensure a comfortable working position for operators of all heights.

• 40V MAX+ lithium-ion power: Advanced Cobra battery system for strong, consistent performance and quick recharging.
• 38cm cutting width: Compact 15" deck ideal for small to medium-sized lawns and tighter garden layouts.
