  • Collection Bag – 55L

We recommend the Hyundai 1966cc Self Propelled Lawn Mower as the best for large gardens on the UK market.

The powerful 196cc 4-stroke engine has a lot of force behind it, allowing you to get the mowing done faster on more extensive lawns. The 51cm cutting width combined with a 70-litre grass bag means you can cover a vast area without stopping.

There are six cutting heights ranging from 25mm to 75mm. With this powerful petrol motor, the higher setting allows you to tackle long or wet grass.

A mulching plug is included and will shred and deposit the clippings back onto your lawn, providing shade and fertiliser for the soil instead of collecting the clippings in a grass box.

Due to the size of this model, you may not be able to get it in and out of tighter areas, so it would be advisable to consider this if you have narrow passages. However, the weight of 38.7 Kg is not a problem while mowing as the machine is self-propelled and easy to manoeuvre.

The handles can be folded down, making it easy to stow and transport.

  • Collection Bag – 26L

The Lawnmaster Hover Mower floats on a cushion of air, making it lightweight and easy to manoeuvre. This is especially useful on curved lawns, sloping gardens and tight spaces.

Although lightweight at 8kg, this mower has plenty of power and can tackle harsh cutting conditions with its 1800W motor with T-Drive (TM), automatically adjusting the blade speed to suit the grass conditions, whether long or wet.

The grass clippings can be cut, collected and compacted into the translucent grass box, or you can mulch the cuttings to add nutrients back into the lawn. Its reversible blade is sharpened on both sides to double its lifespan.

It has a 36cm cutting width with a 15m power cable making this mower ideal for medium to large lawns.

With an expansive deck of 53cm, the Cobra MX534SPH is ideally suited to cutting large lawns, and while the rotary blade provides an excellent cut, it is better suited to flat, even areas without any obstacles.

An optional swing tip blade is available with this lawnmower. The 4-blade swing tip system can reduce the risk of damage to the crankshaft if you are cutting in areas with rocks or tree roots.

How to Buy the Best Lawn Mower for Large Gardens

Mowing a large lawn can be a long and arduous task and having the wrong mower can decrease your efficiency and make cutting the lawn something you dread. The following factors must be considered when choosing the most suitable mower for your large lawn:

Type of Lawn Mower

Lawnmowers can be categorised as petrol, corded or cordless.

  • Petrol lawnmowers are powerful with the capacity to cut through thick, long grass. They can operate in wet conditions and are reasonably cheap to run. Worrying about battery life or the power cable’s length is unnecessary.
  • Electric corded lawnmowers require electric cables and a power point which can be less practical when mowing large lawns as most lawnmowers only have a 10-metre power cable and would need an extension cable to cover large gardens.
  • Cordless lawnmowers offer all the benefits of a corded unit. However, it is essential to consider purchasing a mower with a long battery life or buying a spare battery to increase the run time to enable you to complete mowing your expansive garden area. Cordless mowers also include robotic lawn mowers. While they are generally designed for smaller gardens there are some models that work on larger gardens.

Weight of Lawn Mower

The mower weight can vary considerably from petrol mowers that often weigh more than 30kg to electric mowers that can weigh as little as 10kg or less. Cordless mowers often weigh even less but are generally not suited to larger gardens.

Although most petrol mowers are self-propelled, they still have to be moved from the garden to the storage area, and if they are heavy, this could be a difficult task.

Essentially, the best lawn mower for you will be one that’s comfortable to manoeuvre around your garden for long periods.

Cutting Width

If you have a sizeable open stretch of lawn, a wide cutting width will allow you to mow the lawn in fewer passes and enable you to mow more quickly. A 45cm to 53cm cutting width is recommended for expansive areas.

If your garden has obstacles such as trees, furniture or garden beds to manoeuvre around, it may be advisable to consider a lawnmower with a narrower cutting width.

Adjustable Cutting Heights

Adjustable cutting heights allow you to adjust the cutting height to suit the length and thickness of your grass. For example, if your grass grows very fast or you tend to let your grass get too long, you will need a cutting height of at least 70mm.

A cutting height of around 20cm is ideal for a short, neat-looking property.

Grass Collection

A collection bag with a minimum capacity of 50L is required if you have a sizeable mowing area. Anything smaller means emptying the collection bag more often, thus interrupting your mowing.

Mulching

If you want to improve your lawn’s health, a lawn mower with a mulching option is worth considering. Mulching can make your soil richer and save time due to not having to empty the collection bag frequently.

Comfort and Ease of Use

Mowing a large garden can take a long time, therefore, having handles that you can adjust to a comfortable height is essential. In addition, rubber grips will reduce the vibration if you have a petrol mower.

Petrol mowers tend to be heavy so check the weight of the lawn mower and look for features that will make it easy to move from storage to lawn. For example, large wheels will help to move your mower in and out of storage.

Frequently Asked Questions

What type of lawnmower is easiest to use?

If you have a large area that needs mowing, then a self-propelled petrol lawnmower is the easiest to use. It uses the engine to power the blade and wheels so you merely have to steer the mower where required.

Self-propelled mowers are easier to use, especially if you have a substantial and hilly yard.

What size mower do I need for a small yard?

For smaller lawns up to 300 square metres, we recommend using an electric corded or cordless battery lawnmower with a cutting width of 30cm to 45 cm.

Conclusion

If have an expansive lawn and want to maintain an immaculate garden quickly and efficiently, you must choose a lawn mower capable of achieving the tasks you need it to perform.

With a wide variety of lawnmowers available, we trust that after considering all the factors and recommended mowers in this guide, you can choose the lawnmower for large lawns that best suits your needs and requirements.
