If you are looking to purchase a new lawn mower or want to upgrade the existing machine, you are on the right page. We will review some of the best value petrol lawnmowers today and then you can choose the right option for your lawn.

Buying Guide of The Best Petrol Lawn Mower

Manual push or self-propelled: Petrol mowers UK are divided depending upon the propulsion or we can say power source. Your choice should depend upon the size of your lawn.

Push or walk-behind mowers are entry-level lawn maintenance machines. Such tools are affordable, but they need your physical energy to move. Hence, the push mowers are suitable only for a lawn up to 800 square meters. If you own a garden with multiple flower beds, fountains or decorative stones, try a small petrol mower because it will be easy to manoeuvre around tight corners.

Self-propelled mowers are designed to move without applying any physical efforts. You simply need to guide such a machine and it will do the needful. A self propelled petrol lawnmower with roller is more stable and easy to use. So, try such a lawn tool if you own a garden up to bigger than 700 m².

Power: The capacity of a lawn mower depends upon its engine. You can check it easily because we have mentioned it everywhere in cubic centimetres (cm3 or cc). So, invest in the best petrol lawn mower UK depending upon its power.

If you own land between 800 to 1200 m², then try a machine with displacement anywhere between 100 to 135 cc. Similarly, an engine between 135 to 150 cc is suitable for lawns up to 1500 m². If you have an area between 1500 to 2500 m², then try any option between 150 to 200 cc.

Features to look out for:

Size of mower: The cutting width of good petrol lawnmowers varies anywhere between 40 to 61 cm; depending upon the make and model. The deck size determines how long a mower will take to cover your lawn. A lawn tool with a larger blade can cover more in less time; irrelevant of its speed.

If you own a lawn up to 500 m2, then try a deck size between 33 to 41 cm. For an area between 500 to 1000 m2, you can go for a cutting width between 41 to 46 cm. In case you need to cover a big garden anywhere between 1000 to 2500 m2, then you will need a blade between 48 to 55 cm. For more than 2500m2, we recommend that you try a riding mower.

Starting options: After reading the petrol lawn mower reviews, you can understand that the number of cutting heights depends upon the make and model, but it generally varies between 14 to 76 mm. You can try a mower with maximum level adjustments for added convenience.

You need a cutting height of 25 to 30 mm for smooth and well-trimmed awn grasses. For a classic lawn, a cutting level of 35 to 45 mm is perfect. If you came back from a long holiday, then there are chances you need to use the maximum.

Size of clipping bag: Lawn owners generally spent a lot of time emptying the grass collector. So, purchasing a mower with a significant clipping bag is suggested, especially if you have a large garden. For instance, a 50-litre grass storage bag is suitable for lawns up to 1200 m².

Look for more capacity if you own a larger area. We recommend that you try one of the best petrol lawn mowers that comes with a grass level indicator. It will make the lawn maintenance session convenient by telling you the right time to dispose of the clippings.

Variety of cutting settings: Grass collection is a common feature in petrol lawn mowing units. But, you need to put extra efforts to detach the box, dispose of the grasses and reattach it. Almost all the mowers allow you to remove the grass box for rear discharge, but side discharge is not available in all of them. Mulching is the third option that we will cover next.

Mulching abilities: The mulch plug is not a standard feature of petrol mowers. Mulching is a process where small grass cuttings are discharged back to the lawn so that they can dissolve in the soil. These clippings improve the nutritional level of the soil, which leads to healthy and green grasses.

So, a petrol mulching lawn mower can fertilize your lawn naturally. But, not all lawn owners use this feature. However, we suggest that you invest in a tool that can reduce your investments in lawn fertilizers.
