The good news is that Mountfield has an instructional video on their YouTube channel which shows you exactly how to do it. If you feel you can handle the 20kg weight and you’d prefer to save yourself some money, Mountfield make the same mower without the self-propelling feature.

Engine: 100cc, 4-stroke; Cutting Width: 39cm; Grass Box Capacity: 40 Litres; Self-Propelled: Yes; Weight: 20kg; Self-Propelled: Yes; Warranty: 2 Years; 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.

However, for many people, pushing them up and down the lawn can be tiring work, especially when mowing up and down inclines.

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 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 This Mountfield mower is powered by a 100cc overhead valve engine which is easy to start and economical to run. Self-Propelled 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.

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. Its 39cm cutting width, 40-litre grass bag and lightweight make it a joy to use on small to medium-sized lawns. Assembling this mower is pretty straight forward. Unfortunately, the instruction manual does a pretty poor job of explaining how to do it.

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.

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. The Mountfield SP41 is an excellent, self-propelled petrol mower which is fairly cheap but cuts beautifully. As an example, my own rear garden is about 15 metres long and 7 metres in width. Multiply those 2 numbers together and you get 105 square metres. Then repeat that process for all your gardens and you will get an approximate square metre size. For me, the engine started first time however, if it doesn’t press the primer button a few more times and try again.
