For me, the engine started first time however, if it doesn’t press the primer button a few more times and try again. However, when I got the grass down to a manageable height, the 40-litre collection bag was plenty big enough. Maintenance That said, if you simply want to get the job done and you’re not fussed about stripes, ignore this criticism. The Mountfield SP41 is an excellent, self-propelled petrol mower which is fairly cheap but cuts beautifully. If creating a striped finish when you mow the lawn is important to you, choose another machine. This mower has wheels instead of a rear roller so it won’t leave stripes.

Engine: 100cc, 4-stroke; Cutting Width: 39cm; Grass Box Capacity: 40 Litres; Self-Propelled: Yes; Weight: 20kg; Self-Propelled: Yes; Warranty: 2 Years; Its 39cm cutting width, 40-litre grass bag and lightweight make it a joy to use on small to medium-sized lawns. So, if you push your mower down one length of your garden, the cutting width is the width of grass your mower will actually cut. A mower with a 39 cm cutting width for example, will cut 39cm of grass, so to cover a metre will take 3 passes of your mower. If you have a mowing strip at the edges of your lawn, this won’t be an issue as you can just roll the mower right along.The good news is that Mountfield has an instructional video on their YouTube channel which shows you exactly how to do it. This mower has a 39cm cutting width and a 40-litre grass collection bag which makes it a good option for small to medium sized lawns up to 400sq meters. This made pushing it up and down the lawn a breeze, even on inclines. It’s not the easiest to manoeuvre around tight curves but then, no lawn mower is. Yes, it's very unlikely that the spring has weakened in such a short time, but that's not to say that a wee link somewhere hasn't failed or loosened.

I’ve spent several weeks with the Mountfield SP41 and for medium sized lawns, it’s really quite good. AssemblyAssembling this mower is pretty straight forward. Unfortunately, the instruction manual does a pretty poor job of explaining how to do it.

Setting the mowing height consists of adjusting three levers. There is a lever for the rear wheels and the front wheels need adjusting individually. The mechanism is smooth and it takes seconds.

All lawnmowers have a cutting width, and that can range in size from as low as 30cm (12") up to around 53 cm(21")

There are various mechanisms used to control that lever - sometimes the stiff wire link disappears in to the engine casing and is controlled from something internal, and other times it's from a curved 'flap' which sits close to the fan at the top of the engine - the faster the engine spins, the further the paddle (which is in the air flow) moves. The Mountfield SP164 is a step up from the HP164 with the addition of self-propelled drive. The mower matches your walking speed and takes the effort out of pushing the lawn mower across long grass or uneven ground. It doesn’t have a rear roller so if a striped finish is important to you, you might want to choose another model. Also, the instruction manual isn’t the best. That said, there are instructional videos on YouTube. The SP164 has two mowing options for your grass cuttings, either collect to the aerated 40 litre grass bag, or remove the collector to eject the grass cuttings directly onto the lawn. It’s small, fairly basic, but well priced while at the same time being good quality. 100cc OHV Engine
