Mountfield 1640S
Best OverallPros
- Powerful 190cc engine handles thick grass
- Large 70L grass collector reduces emptying stops
- Easy-start system with primer bulb
Cons
- Heavy at 32kg, not ideal for small sheds
- No mulching plug included
The Mountfield 1640S is built around a reliable Briggs & Stratton 500E engine, delivering consistent torque for cutting through damp or overgrown grass. The 53cm steel deck provides a wide cutting path, making it efficient for lawns over 500sqm. Owner reviews consistently praise the self-propelled drive for reducing fatigue on uneven ground, though some note the transmission can feel slightly jerky at low speeds.
Grass collection is handled by a 70L soft bag, which is generous for the cutting width. The six cutting heights range from 25mm to 75mm, adjustable via a single lever. While the mower lacks a mulching kit out of the box, an optional accessory is available. Overall, it's a durable workhorse for larger gardens.
Mountfield 1350S
Best BudgetPros
- Lightweight and easy to manoeuvre
- Folds for compact storage
- Reliable start and simple operation
Cons
- No self-propelled drive
- Smaller 40L grass collector
The Mountfield 1350S is a straightforward push mower designed for smaller lawns up to 300sqm. Its 125cc engine starts reliably, and the 40cm cutting width is sufficient for tight spaces and borders. Owners appreciate the foldable handle, which reduces storage footprint significantly.
The 40L grass collector is adequate for a mower of this size, though you'll need to empty it more frequently on longer grass. Cutting heights are adjustable from 25mm to 70mm across five positions. While it lacks the power of larger models, it's a solid entry-level choice for budget-conscious buyers.
Mountfield 1530SP
Best for Medium GardensPros
- Smooth self-propelled drive for medium lawns
- Good balance of power and weight
- Decent 60L grass collector
Cons
- Engine can struggle in very wet grass
- No rear roller for stripes
The Mountfield 1530SP sits between the entry-level and premium models, offering a 46cm cutting width and a Briggs & Stratton 450E engine. It's self-propelled, making it suitable for lawns up to 500sqm with gentle slopes. Owner feedback highlights the smooth drive engagement and easy height adjustment.
The 60L grass collector is practical for medium gardens, and the steel deck feels robust. However, some users report the engine lacks torque in wet conditions, leading to clogging. It's a strong all-rounder for typical UK lawns, offering good value without the premium price of larger models.
Mountfield 1720H
Best for Hilly TerrainPros
- Hydrostatic drive offers variable speed control
- Powerful 190cc engine for steep slopes
- Large 80L grass collector
Cons
- Heavy and bulky to store
- Premium price point
The Mountfield 1720H features a hydrostatic transmission, allowing infinitely variable speed control without gears. This makes it ideal for hilly terrain where consistent traction is needed. The Briggs & Stratton 675EXi engine provides ample power for thick grass and inclines.
The 80L collector is one of the largest available, reducing stops on large lawns. Cutting heights are adjustable from 25mm to 80mm. Owners praise the smooth drive but note the mower's 35kg weight makes it challenging to manoeuvre in tight spaces. It's a premium choice for challenging gardens.
Mountfield 1420S
Best for Small LawnsPros
- Compact and easy to store
- Lightweight for easy pushing
- Simple maintenance
Cons
- No self-propelled option
- Small 40L collector
The Mountfield 1420S is a compact push mower with a 42cm cutting width, ideal for lawns up to 250sqm. Its 125cc engine is easy to start and maintain, and the steel deck offers durability. Owner reviews note it handles regular cutting well but struggles with overgrown grass.
The 40L collector is small but manageable for small gardens. Cutting heights range from 25mm to 70mm. It's a basic, no-frills mower that gets the job done without unnecessary features. For small, flat lawns, it's a cost-effective choice.
What to check before buying a Mountfield petrol lawn mower
Consider your lawn size: models with cutting widths of 40-46cm suit small to medium lawns, while 53cm decks are best for large areas. Self-propelled drives reduce effort on slopes, but add weight. Check the grass collector capacity: larger bags (70-80L) mean fewer stops. Engine power is measured in cc: 125cc is fine for regular cutting, while 190cc handles thick or wet grass. Also verify the cutting height range and adjustability mechanism.
Mistakes to avoid when choosing a Mountfield mower
Don't buy a push mower for a large, hilly lawn: you'll exhaust yourself quickly. Avoid choosing based solely on cutting width without considering storage space. Many owners also overlook the importance of a mulching kit if you want to recycle clippings. Finally, check the warranty length: Mountfield typically offers 2 years, but some retailers may offer extended cover.
