Mountfield SP41 Petrol Lawnmower, Self-Propelled, 39cm cutting width, 123cc ST120 Autochoke petrol engine, Up to 250m², Includes 40L Grass Collector

Needed a new mower at very short notice to replace a 14 year old Hayter which had given excellent service. At my age I’m not looking for long term use, weight, ease of use and self propelled were my criteria plus of course cost. The SP41 came out best buy on that criteria and reviews here and on YouTube. Ordered Wednesday and delivered next day, exceptional service from the delivery man who carried it into my shed for subsequent assembly. The instruction manual with the mower is almost useless, without the YouTube videos I’d have struggled to fit the grass collector together. However, Iwith prior knowledge it was easy and was accomplished in less than an hour which at 76 years old I reckon wasn’t too bad. It started first pull and off I went, my first experience of a self propelled mower and what a revelation. Why have I struggled with a pusher for all these years. I cut my sizeable garden in half the time my old pusher Hayter managed and to a very good standard. It’s only been used once but if it continues at this rate I’m a very happy chappie with my SP41. I’d recommend it.

Excellent value for money. Bought due to the products ability to mow grass to a very low level due to the easy adjustable handle at the side of the machine. Looks stylish but also easy to use and powerful. Starts immediately. I would highly recommend and as a result two neighbours also purchased this product as they were impressed by its results! Recommending to my local bowling team too.

Easy to set up, easy to fill, easy to use. I went round twice but the first pass would have been enough. The pull along system isn't too heavy and as long as you feather it, the control is more than enough. Note to others: The mower says it comes without oil, however mine did. Check your dipstick before adding oil.

First the pro points. Its as light as a Petrol mower gets. I had no problem putting the handle on, on my own however, I had to squeeze the 2 arms closer together as they were a bit far apart when offered up. Ideal for the smaller garden. Starts easy. On first use after filling with Petrol it started 3rd pull and first time thereafter. The 2 previous pulls needed to prime the carburetor. Good enough and light grass collector. Easy to adjust cut length via the wheels. Sturdy enough for an economy model. Folds away to store in a small space. The speed is fine perhaps it could even be a bit slower for some. Cuts well. I haven't tried it on long grass however. Now the cons. The folding of the handle to facilitate compact storage could be better. Locking levers maybe as you have to unwind the plastic star locking turns quite a lot to fold the handle. You need to be careful not to unscrew the star locking turns too far and lose the back nut. Could do with a handle at the rear to help lift the mower over obstacles and into storage boxes. I would have liked a longer engine pull cord given you have to pull the tart handle back before pulling the engine starter cord. Some people might struggle to do both at the same time. Other models in the range have longer engine pull cords attached to the handle close to the squeeze start bar. You need a funnel with flexible extension to put oil in. Perhaps they could provide one. All in all not real complaints for the money and I would buy again. I would have given it 5 stars if it had a couple of the features I would have liked to have on it.

Looks the part, assembly is quite simple although the manual is a bit hard to interpret and a one person job and takes about 10-15 minutes to assemble. The grass collection is amazing and quick on it. The quality is top class and the cutting heights are great. The size is average on it. The noise level is a bit loud but can’t complain due the amazing quality of this self propelled lawnmower.

Bought in May 2025, all worked well, put it away and got it out to use early 2026, it would not start, pulling away and nothing, I changed the fuel, nothing, they do not have a choke or fuel pump so you have no control over that, went through Amazon support and then to Mountfield support, I sent them the model, purchase date, receipt details, everything, Mountfield literally ignored my contact, so the machine would not start ans Mountfield do not even reply, avoid this one and especially avoid a company who ignores its customers They praise up a no choke or no fuel pump as a benefit, no it is not, as it takes away your control, if the machine wont start up are limited in what you can do, no choke or pump is a crazy idea they make out to be a benefit which it really is not

Excellent lawn mower! Very pleased with it.

A lightweight mower, I bought this on the strength off good reviews, have used it once and it did what I wanted, easy to ,assemble,( only the collector bag took me a few minutes to work out how to put together) put oil in and petrol and it was as asy to start as the reviews said , All in all very happy with this mower, and would recommend it.
