Mountfield HP42 41cm Petrol Rotary Lawnmower
The HP42 is Mountfield's entry-level petrol push mower and it covers the basics well — a reliable 123cc Stiga ST120 Autochoke engine, 41cm cutting width, and a robust steel chassis at a price that represents genuine value for a small to medium garden.
The Autochoke engine removes the need to manually set a choke before starting, which is one of those small details that makes a real difference on cold mornings. Pull the cord and it starts — no fiddling with choke levers or primer bulbs. The steel chassis gives it a solidity that plastic deck mowers at similar prices can't match, and at 23kg with fold-down handles it's still straightforward to store.
Six cutting heights from 25-70mm are adjusted via a centralised lever that sets all four wheels simultaneously, and the 60-litre textile collection bag with bag-full indicator is generous for the cutting width — the indicator means you're not stopping to check whether it needs emptying. The mulching plug is included in the box, so switching to nutrient-returning mulch mode requires no additional purchase.
A 5-year manufacturer's warranty is included.
