Choosing the Right Walk-Behind Mower

A walk-behind mower should match how you mow as much as the size of your lawn:

  • Lawn size: Smaller lawns suit compact electric or cordless mowers, while medium to larger domestic gardens benefit from wider-cut petrol models.
  • Effort level: Push mowers offer simplicity and control, while a self-propelled lawn mower reduces effort, especially over longer mowing sessions.
  • Terrain: Flat lawns are easy to manage with most models, but slopes or uneven ground are better handled with self-propelled machines.
  • Power type: Petrol delivers strength and runtime, cordless offers flexibility and low noise, and electric models provide a simple, lightweight solution.

Not sure which direction to go? We can guide you through the options.

Types of Walk-Behind Mowers in Our Range

Petrol Lawn Mowers

Petrol models are ideal for larger lawns or tougher conditions, offering the power and runtime needed to cut thicker grass efficiently.

Cordless Lawn Mowers

Cordless mowers provide a quieter, more flexible way to mow, with modern battery performance that suits most domestic gardens without the restriction of cables.

Electric Lawn Mowers

Electric models are a simple, lightweight choice for smaller gardens. They’re easy to handle and ideal where you want straightforward, low-maintenance mowing.

Self-Propelled Lawn Mowers

A self-propelled lawn mower takes the effort out of mowing by driving itself forward, making it easier to cover larger areas or tackle slight slopes.

Push Mowers

Push mowers offer full control and are typically lighter, making them well suited to smaller, flatter lawns where manoeuvrability matters most.

Roller Lawn Mowers

For a traditional striped finish, roller lawn mowers are the go-to choice, creating clean lines while maintaining an even cut.

5 Key Features That Make a Difference

  1. Adjustable cutting heights let you adapt to changing grass conditions, whether you’re maintaining a close finish or tackling longer growth. 
  2. Mulching options help return nutrients to the lawn, supporting healthier grass over time.
  3. Self-propelled drive, especially with variable speed control, reduces effort and makes it easier to maintain a steady pace. 
  4. Wider cutting decks cover more ground in each pass, helping you finish faster, while efficient grass collection systems mean fewer stops to empty clippings.
  5. Durable deck construction, such as steel or aluminium, adds long-term reliability, ensuring your mower stands up to regular use and changing UK conditions.

Walk-Behind Mower FAQs

What is the difference between a push mower and a self-propelled mower?

A push mower requires you to drive it forward yourself, giving more control on smaller lawns. A self-propelled mower moves under its own power, reducing effort over longer distances or uneven ground.

Should I choose petrol, cordless, or electric?

Petrol mowers suit larger or more demanding lawns thanks to their power and runtime. Cordless models offer convenience and low noise, while electric mowers are a simple choice for smaller gardens.

Which mower is best for stripes?

Roller lawn mowers are designed to create a classic striped finish by bending the grass as you mow, giving that traditional lawn appearance.

Should I buy a rotary or cylinder mower?

Rotary mowers are versatile and handle most lawn types well. Cylinder mowers are better for fine, formal lawns where a very precise cut is preferred.

Do you assemble mowers before delivery?

Yes. We fully assemble, test, and demonstrate each mower locally so you can start using it with confidence.

Do you offer servicing and repairs?

Yes. Our on-site workshop provides servicing, repairs, and blade sharpening to keep your mower performing reliably year after year.
