Mountfield HP42 Hand-Propelled Petrol Lawnmower

Enjoy superior build-quality and get a host of practical and convenient features at a rock-bottom price with the British-designed Mountfield HP42 Hand-Propelled Petrol Lawnmower!

Supplying the blade with a substantial 2.5hp is a STIGA ST 120 engine; a super-efficient 123cc four-stroke air-cooled motor, which, thanks to its overhead-valve design, will prove cheap to run, clean burning, and smooth and quiet in operation.

In addition to the traditional ‘cut & collect’ option, the Mountfield HP42 Hand-Propelled Petrol Lawnmower also offers a mulching mode – instead of being bagged, clippings are held under the deck and shredded, with the resulting mulch being forced back into the turf by a powerful airflow, where it will quickly rot and disappear.

The Mountfield HP42’s straightforward hand-push design and narrow 41cm cut combine to make it highly manoeuvrable and therefore ideal for less substantial areas where there are obstacles and landscaping around which to work.

It’s supplied with a roomiest-in-class 60-litre grassbag, which is made from breathable canvas to maximise catcher capacity, and it features ‘collector full’ indication, so it’s unlikely you’ll overfill and block the discharge chute.

In order to help you achieve your desired finish, the manufacturers have furnished the Mountfield HP42 with six preset heights of cut (22-65mm) which, unusually for a mower in this price bracket, are selected using just a single lever.

Also important on the Mountfield HP42 is its steel chassis, which provides rugged durability, and acts a solid cutting platform.

It should be noted that Mountfield petrol lawnmowers are covered by an extended five-year manufacturer’s warranty*.

* Ts & Cs apply – to maintain a valid warranty, the machine must be serviced annually from year two onwards by an authorised dealer

Shipping Info

Shipping Info

If you’re buying a boxed product, we aim to get your order delivered next working day – UK mainland where possible.

If you’re buying a tractor or ride-on mower – a special order item – it could be slightly longer, as we need to PDI the machine.

We do try and van-deliver these machines if we can, as this gives us a chance to demonstrate the product, and to ensure you’re happy and confident with your purchase.

If we can’t van-deliver your machine, as you’re out of our local delivery area, the tractor will be sent on a pallet via a courage company. They will then contact you directly to book a specific day and time that suits you.
