If you’re seeking an environmentally-sound alternative to your old, high-emission petrol mower, then the Snapper NX-40 is definitely worth considering. It’s powered by a high-performance 140cc Briggs & Stratton 550E-series engine which incorporates emission-minimising EVE™ technology. As a result, evaporative emissions are reduced by an amazing 72-percent. Like all B & S engines, the 550-series models are exceptionally reliable and fuel-efficient.A key characteristic of the Snapper NX-40 Petrol Rotary Lawnmower is its power-drive to the rear-wheels. Because there’s no need to push, you’ll be able to traverse slopes, undulating areas and rough-grass sections with little or no effort expended. The drive wheels are mounted on ball-bearings for durability.The three-in-one Snapper NX-40 incorporates a rear-deflector and can be paired-up with a mulch-plug (optional), so it can be used without the large 60-litre-capacity grass-catcher where conditions suit. It boasts an multi-stage height-of-cut (28-92mm), so you can make sure the finish is exactly as you want it; and it’s built around a robust steel chassis that bestows strength and rust-resistance, in turn ensuring you’ll get years of service from your mower.Other quality features include larger diameter drive-wheels for improved traction on adverse terrain; and an ergonomic soft-grip handlebar, which ensures you’ll be able to complete the job in comfort (the handle folds forward for hassle-free storage).
