Einhell GC-PM 46 S Petrol Lawnmower UK Review 

By  Enda

Thanks for taking the time to read our UK review of the Einhell GC-PM 46 S Self Propelled Petrol Lawnmower. This is a powerful and a popular option for many UK gardeners.

The Einhell GC-PM 46 S petrol lawnmower is a good choice for larger gardens, and according to online buyers is well made and robust in nature, which of course offers many years of service.

There are many petrol mowers available on the UK market. Online buyers like this Einhell (a German brand) model, as it is easy to start, and easy to use. The self propelling action makes mowing pretty easy, emptying the grass box is straightforward and when compared to other models, this appears to be really good value for money.

Who Should Buy this Mower?

Einhell GC-PM 46 S Petrol Lawnmower


  • A good choice for any gardener who has medium to larger gardens that for the most part are straight (up to 1,400 square metres)
  • Gardens with longer grass as on the highest cutting this mower easily deals with that, and then you can easily reduce the cutting height 
  • Petrol mowers are known to be difficult to start, and this model is very good at starting first time
  • If you are willing to spend around £200, then this is as good as any other petrol mower we have seen, at that type of price point

Should Not:

  • Avoid if you have a narrow garden or one with a lot of obstacles as this mower doesn't manoeuver easily 
  • At 35 Kg this is a heavy mower, so moving it around requires effort, so not ideal for senior people, or anyone with back or knee issues
  • Some buyers experienced difficulty getting spare parts for this mower, so that coule be a long term issue


Hopefully the above information gives you a better understanding of the type of use you will be able to get from this mower. Overall, online buyers have given this GC-PM 46S model an 86% buyer satisfaction.

  • 63% of all buyers gave this a full 5 star review

Our Opinion on the Einhell GC-PM 46 S

Is it value for money?

Petrol mowers cost on average between £180-300, so this model does sit at the lower end of the price point, for this standard and class of mower. The price point therefore makes this an attractive option for many people. It is clearly good value for money, so it ticks that box.

Does this mower cut well?

The vast majority of buyers said the mower starts first time and is very easy to use. The petrol consumption is good and it is well made with a strong housing, and very good blades. It is suitable for gardens of up t0 1400 square metres, which is a big garden.

It can be used without the self-propelling feature and it is even easier to use when this feature is used. All buyers said the grass collection system is very good.

The cutting width, and range of cutting height options is very good, so no real complaints with its overall cutting performance.

Customer Service and After Care

This is where the main complaints arise about this mower. You may have noticed earlier that we mentioned 17% of all buyers gave this mower a poor review. There does seem to be an issue with getting spare parts should anything go wrong.

The warranty on this mower is 2 years, which is standard, and you are covered under the warranty. After the 2 year period is where the problems appear to be. There is an Einhell service website for parts which you can see by clicking here.

We checked it out, and some parts were available, but not all of them.

In addition to this a couple of buyers said the blades came off when using it. You should consider the above information before making any purchase. To balance this out, most buyers do appear to be happy with their purchase with two thirds of buyers giving this model a 5 star review.

My Opinion

  • We hope that we have supplied you with some useful review information
  • There are over 500 online reviews, so we do know that this model sells well and has done so for a number of years
  • Assembly is very easy when compared to many other brands, and it does look really good and is overall well designed and well made
  • It is a good choice for medium to large gardens and has all the right features
  • The main draw back is that it might be difficult to obtain spare parts if the mower ever needs some part replaced
  • Check Amazon UK - Price when reviewed £400.00

We have completed a top 10 list of petrol lawnmowers. This Einhell model came in at number 10 on the list, in terms of buyer satisfaction. Despite that lower position, this model does continue to sell on a consistent basis.


I am someone who enjoys a little gardening. Now I am not someone who spend hours in the garden, but I do like both my front and back gardens to look really nice. Well kept lawns, neatly trimmed hedges, and borders filled with plants, make a huge difference, to how your property looks.
