Ideal for medium lawns, the MX4140VX is a hand-propelled, steel deck cordless lawn mower powered by the advanced Cobra 40V MAX+ lithium-ion battery system.
This versatile lawn mower is equipped with a 41cm (16") deck and features seven stage height adjustment from 25mm for a superb low finish, up to to 75mm for tackling longer grass. The height of cut adjustment is achieved simply via a single lever conveniently positioned next to the rear wheels. Grass clippings are collected into a spacious 50 litre grass catcher with bag full indicator. The included mulch plug offers eco-friendly cutting options, so you can choose to finely chop the grass clippings and return them to the lawn. This process recycles nutrients back into the soil, promoting healthier grass growth and reducing the need for chemical fertilisers.
Weighing 20kg, the push-propelled Cobra MX4140VX is easy to manoeuvre and built with a durable steel cutter deck. The cutter deck is designed with front grass combs which lift and guide the grass into the cutting blades to ensure a cleaner, more efficient cut.
The soft grip handles on the MX4140VX offer enhanced comfort, reducing vibration and providing a more enjoyable mowing experience, whilst infinite handle angle adjustments allow for personalised comfort for operators of all heights.
