Our take

The Easy 4.2 P-S might not be the most exciting mower ever, but if you just want the grass cut, this inexpensive, hard-wearing metal gem is a fantastic choice.

At 42cm, the cutting width beats out the mains electric offerings while remaining compact and easy to store, and the unified height adjustment lever has 7 stages to give a good level of control over the height of cut.

It’s also unbelievably lightweight, rivalling battery machines for mobility, while retaining the petrol grunt of AL-KO’s own engine. No thrills, no spills – just the kind of efficiency you’d expect from a German-designed machine.

From the manufacturer

Lightweight and agile: this is how the Easy Lawnmower presents itself at an attractive price – This is how lawn mowing becomes a pleasure!

The Easy 4.20 P-S mower impresses with its excellent price-performance ratio.

With its reliable technology, the Easy 4.20 P-S petrol lawn mower makes it easier for you to work in your garden.

The 50L fabric grass collector is easily attached to the aerodynamic steel deck which provides impressive mowing performance and a long service life.

This petrol lawn mower has a cutting width of 42cm / 16” and makes for easy and manoeuvrable mowing in lawns up to 800m2.

The cutting height can be adjusted centrally in 7 stages using a single lever and with mowing heights ranging from 30mm to 75mm, you can be sure to get the desired finish on the lawn.

Featuring an easy-to-start AL-KO Tech 140 engine with primer, an ergonomically designed handlebar and smooth-running wheels, this mower is both simple and comfortable to operate.

Thanks to the aerodynamic sheet steel cutter deck, optimum collection results are achieved.

The large 50-litre grass collector means that it requires emptying less often allowing you to get the mowing work completed quickly.
