Mountfield 40V 36cm Cordless Lawn Mower
Best OverallPros
- Excellent cut quality with striped finish
- Lightweight and easy to manoeuvre
- Quiet operation
Cons
- Grass box could be larger
- Not self-propelled
This 36cm model is the sweet spot in Mountfield's cordless range. It delivers a clean, even cut that rivals petrol mowers, with the added benefit of near-silent operation. The 40V battery provides ample runtime for a typical 200-300 sqm lawn, and the single-lever height adjustment makes switching between cuts quick.
Owner reviews consistently praise its build quality and the attractive stripe pattern it leaves on the lawn. The 40-litre grass box is adequate for most cuts, though you may need to empty it more frequently on very long grass. It is a push mower, so those with sloping gardens might prefer a self-propelled option.
Mountfield 40V 46cm Self-Propelled Cordless Lawn Mower
Best for Large LawnsPros
- Self-propelled drive reduces effort
- Wide cutting deck for faster mowing
- Large grass box capacity
Cons
- Heavier than push models
- Higher price point
For lawns over 400 sqm, this self-propelled 46cm mower is the ideal choice. The variable speed drive lets you match the pace to your walking speed, making mowing less tiring. The 4.0Ah battery gives enough runtime to finish most large lawns on a single charge, and the 55-litre grass box means fewer stops to empty.
Owner feedback highlights the robust build and the ease of starting compared to petrol alternatives. The cut quality remains excellent, with Mountfield's signature roller stripe. It is a heavier machine, but the self-propulsion largely negates this. Some users note the handle could be more padded for comfort on longer sessions.
Mountfield 20V 32cm Cordless Lawn Mower
Best BudgetPros
- Very lightweight and easy to carry
- Lowest price in the range
- Ideal for small city gardens
Cons
- Smaller cutting width and grass box
- Not suitable for thick or wet grass
This entry-level 20V model is perfect for small gardens, patios, or allotments. At just 11.2 kg, it is incredibly easy to lift and manoeuvre, even for those with limited strength. The 32cm cutting width is nimble around flower beds and sheds, and the 2.0Ah battery provides enough power for a quick weekly trim.
Owner reviews note it is surprisingly capable for its size, delivering a neat finish on maintained lawns. The 25-litre grass box is small, but for a 100 sqm lawn it works well. It is not designed for heavy-duty tasks or overgrown grass, but for regular maintenance of a small space, it is excellent value.
Mountfield 40V 41cm Mulch & Collect Cordless Mower
Best for MulchingPros
- Dedicated mulch plug for fine clippings
- Good balance of width and weight
- Versatile collect, mulch, and rear discharge
Cons
- Mulch performance best on dry grass
- No self-propulsion
This 41cm model is designed for those who want to return nutrients to the lawn. It comes with a mulch plug that chops clippings finely and drops them back onto the grass, reducing the need for fertiliser. The 40V motor provides consistent power, and the 45-litre grass box is a good size for collection mode.
Owner reviews appreciate the versatility of the three cutting modes and the tidy finish. On dry grass, the mulching is excellent, leaving no clumps. It is a push mower, so it requires some effort on slopes, but the 41cm deck is a good compromise between speed and manoeuvrability. Some users found the mulch plug slightly fiddly to install initially.
Mountfield 40V 36cm Self-Propelled Cordless Mower
Best Self-Propelled CompactPros
- Self-propelled drive for easier mowing
- Compact size for storage
- Same great cut quality as the push model
Cons
- Heavier than the push version
- Drive speed adjustment is manual
This combines the popular 36cm cutting width with a self-propelled drive system. It is ideal for those with small to medium lawns who have sloping ground or simply want to reduce pushing effort. The 40V battery powers both the blade and the drive, and the runtime is sufficient for most typical gardens.
Owner reviews highlight the convenience of the self-propulsion and the familiar excellent cut quality. The 36cm deck remains nimble around obstacles. The drive speed is adjusted via a lever on the handle, which some find less intuitive than a variable trigger. It is heavier than the push version due to the drive system, but the self-propulsion makes it feel lighter during use.
What to check before buying a Mountfield cordless mower
Consider your lawn size first. For lawns under 200 sqm, a 32cm or 36cm model is sufficient. For larger areas, the 46cm self-propelled mower saves time. Battery voltage matters: 40V models offer more power and runtime than the 20V budget option.
Check if you need self-propulsion. If your garden is flat, a push mower works fine and is lighter. For slopes or longer distances, self-propelled drive reduces fatigue. Also consider the grass box capacity: larger boxes mean fewer trips to the compost heap.
Mistakes to avoid
Do not choose a mower with a cutting width too small for your lawn, as this will significantly increase mowing time. Avoid assuming all Mountfield batteries are cross-compatible: the 20V and 40V systems are separate and use different chargers.
Do not neglect the importance of a roller for stripes if you value a professional finish. Most Mountfield models include a rear roller, but always check the specifications. Finally, do not underestimate the weight of self-propelled models if you need to lift the mower over steps or into a shed.
