Our Recommended The Best Lawn Mower For Steep Slopes Is The Webb Classic WER410SP Self Propelled 4 Wheel Petrol Rotary Lawnmower!

If you have steep banks on your lawn or maybe your garden is on a hill, finding the appropriate mower is not a simple task, you want to make sure your mower is light enough to handle and push, but also that it has enough power to get up the steep slopes. 

Battery mowers can often be great for steep slopes but lack the same power as self-propelled petrol mowers for tackling hills. 

So to help you out, we've rounded up some of our favourite lawn mowers for steep slopes below, reviewing them individually to see which mower is right for your hilly garden.

Our Favourite Lawn Mower For Steep Slopes - The Webb Classic WER410SP Self Propelled Petrol Rotary Lawnmower

If you have a medium-sized garden on a steep slope and can't find the right powered mower with still a lightweight, this Webb classic petrol mower could be the best pick for you. 

Top features of the petrol lawnmower are a 41cm cutting width and a four-stroke DVO130 engine boasting low fuel consumption, the powerful lawn mower further has seven cutting heights ranging between 25-75mm allowing you to cut both shorter and longer grass. 

A 45-litre grass bag is included with the steep hill lawn mower for collecting clippings, however, you can rear discharge the clippings as mulch too on this mower. The mower is also self-propelled with plenty of power to help get you up those slopes without too much pushing. 

Conclusion 

Overall, this Webb Classic self-propelled petrol mower is one of our favourite picks if you have a type of slope that needs a high powered simple use mower, the powerful model is easy to move around thanks to its self-propelled system and perfect for a medium-sized lawn. 

Downfalls of this Webb petrol model are its grass collection box opening which can be narrow, allowing you to spill clippings easily, the lawn mower additionally is quite heavy to move from the shed and around.

  • Seven cutting heights between 25-75mm.

The main features of this mower are its adjustable cutting heights ranging between 22-80mm, this can be adjusted in five different positions. The 39cm cutting width is perfect for small and medium gardens with grooved wheels which allow for better grip on dodgy slopes. 

Design-wise the lawn mower has a lightweight rust-proof chassis and 40L grass collector box for grass clippings, the handles of the lawnmower fold over too for easier storage.

Conclusion

We rate this Mountfield petrol lawnmower as an excellent powerful mower for hilly gardens thanks to the engine for power yet lightweight design since the mower is mainly made out of plastic, allowing you to get up steep slopes with ease. 

Drawbacks of this petrol lawnmower are its build quality which is reported to have a cheap feel due to its mostly plastic design.
