Bosch Rotak 34R Review – Electric Rotary Lawn Mower

The Bosch Rotak 34R is a nifty and reliable lawnmower that is great value for money. If you are looking for an easy to operate mower for a small to medium garden, this makes an excellent choice.

This mower is the slightly bigger brother of the Bosch Rotak 32R with a 34cm deck size as opposed to 32cm and a more powerful motor.

The Bosch name is known for well priced, hardworking and reliable garden tools. The German-based company has been around since 1886. Their products are easy to use and they are a trusted popular brand.

Let’s take a look at this Bosch Rotak 34R to see how well it performs and it it’s the best choice for you and your lawn!


The Bosch Rotak 34R is a corded mower and needs its 10-metre power cable to be connected to a mains socket that provides a very respectable 1300-watt motor. The build quality is what you would expect from Bosch and being built in the UK makes getting parts easier and cheaper should they be required. A metal blade is used on the 34R as opposed to plastic proving a good cut and allowing for the blade to be sharpened if needed. The 34cm cutting width make it ideal for small to medium lawns and for taking up less storage. There are 5 different cutting heights, this is pretty standard for mower of this size and ranges from 20 to 70mm which is perfectly adequate to adjust to the changing length and conditions of your lawn.

OK, lets take a look at this Bosch Rotak 34R in more detail and see what’s good and what’s not so good with this mower.

Difference between the Bosch Rotak 34 and Rotak 34R

Before we dig into this review, I am often asked what the difference is between the 34 and the 34R, well its quite simple. The Bosch Rotak 34 has no rear roller and Bosch Rotak 34R (R=Roller) does have a roller at the back of the lawnmower. This allows you to make professional looking stripes on the lawn if you so wish.

Power System

The Bosch Rotak 34R features a powerful 1300-watt Power-drive electric motor. That is plenty of power and will give you professional results with minimal effort. It is a decent sized motor so even if you have let the grass get a bit on the long side, you will not have any difficulty.

While it by no means the biggest and most powerful lawnmower around, unless you have a jungle to contend with it will do a perfectly good job with ease.

The cable that comes with the Rotak 34R is 10 meters long so ensure you have enough extension cord to cover the required area.

Also the power system is completely electric so it produces zero emissions and works extremely quietly.

Power cable

The lawnmower comes with a 10-meter power cable. If more range is required an extension cord will be needed. This length of power cable is relatively standard for mowers in this class.


The Bosch Rotak 34R has strong 34 cm steel blades. While these will need to be sharpened occasionally, they will give a clean, neat cut and they are extremely durable. If you ever do need to need to replace them, parts are easily available and reasonably priced.

The 32 cm size is ideal for the small to medium gardens this mower is designed for as it gives a good combination of speed and efficiency while still being easy to maneuver.

The Bosch Rotak 34R is equipped with one blade that gives them two very effective benefits…Bosch Rotak 34R Replacement Blade

  1. Metal blades generally wear less quickly than plastic blades which results in you needing to replace the lawnmower blades more often than a lawnmower that uses a metal blade.
  2. Metal blades are generally sharper and provide a cleaner cut to the grass blade, resulting in a neater, tidier and superior finish to your lawn and garden. And as stated above, the metal blades can be sharpened when needed unlike plastic blades.

So are the blades on the Bosch any better than its nearest competitors? Well, no not really. The blades on the Bosch are good but are no better across other mower brands in this size and class of mower.

As well as being able to sharpen the blades, it is also possible to purchase a replacement blade for the Bosch 32R for around £16 for a genuine replacement. Replacing the blade is relatively easy for anyone with basic DIY skills and tools.


Bosch Rotak 32l Power DriveHeight Adjustment

It essential that your lawn mower is highly adjustable to accommodate different lawn types as well as to accommodate for the different seasons. The Rotak 34R gives you a choice of 5 settings ranging from 20mm to 70mm using a front mounted lever that centrally adjusts the cutting height . No matter what type of lawn you have or what your seasonal requirements are, this mower will be perfectly adjustable for your needs.

If you have left your lawn to grow for a while, don’t rush in and cut it on a very low setting. Rather start on a higher setting and progressively cut it lower. This will avoid leaving an untidy patchy appearance.

Is 5 separate cutting lengths better than the competition, well yes and no. Some mowers at this price point only have 3 height adjustments, however, most will have 5 so it’s pretty much standard.

The height adjustment is very easy and smooth to use and is a big improvement over it’s smaller brother the 32R where you need to turn the mower upside down to adjust the back wheels in any one of the 3 slots. So 5 heights with a top adjustment lever that is easy to use, well done Bosch!

Cutting Diameter

If you are cutting a sports field, the bigger the cutting diameter the better. With gardens, however, this is not the case.

The 34 cm cutting diameter of the Rotak 34R is ideal. It will allow you to zip around the garden in no time but still give the precision and ease of movement for curves and edges.

Remember 34cm is one of the smaller deck sizes so if you have a large lawn, say over 300m², you may want to consider a larger deck size.

Grass box capacity

Having a large grass box is a bit of a double-edged sword. On the one hand, it means that all the trimmings are collected and you need to make a few trips to empty it out. A smaller grass box or no grass box will make the lawnmower much lighter and easier to navigate.

Once again, Bosch has found a great compromise between the two. As this mower is designed for small to medium gardens the 40 litre capacity of the grass box is ideal. It will let you zip around the garden easily without dragging you down while still keeping the trimmings neat and easy to dump. Cutting a larger garden is no hassle, it just means more trips to empty the grass bin, not the end of the world.

The 340 litre size is a good balance of convenience and mobility. It is well designed to be effective at catching much of the grass trimmings, leaving very little, if any raking to be done afterwards. The design is also efficient and compacts the trimmings for maximum space use. While you mow, it will not slow you down or hinder your movements.

The grass box on the Bosch Rotak 34R is very easy to remove and the grass clippings empty from the box with no obstructions.

Bosch Rotak 34R practicalitiesPracticalities

One thing you can expect Bosch to deliver is practical equipment and the Rotak 34R is no exception. Bosch has a great reputation for convenient, easy to use lawnmowers. Many of their lawnmowers have the ‘Ergo flex’ handles which are great and extremely comfortable and easy to work with. The 34R does not have this but it is very unlikely you will notice the difference. The slightly larger Rotak 36R does have the Ergoflex-System.

It is well designed and extremely nimble so it is easy for anyone to use.

As with all corded lawn mowers, being tethered by the cord does mean you may require an extension cable for larger lawns and care needs to be taken not to accidentally cut the cable whilst mowing.

I do prefer the height adjustment to be located central to the mower for ease of use, however, the front mounted lever is very easy to adjust in this Bosch mower.

Does this make it more practical the it’s closest  competition? well, yes I think it does for people with smaller lawns and limited space for storage and at only 11 kg. There is also a well positioned central handle that makes carrying the  mower to the garage or shed very easy.

Safety Features

Another thing Bosch products are known for is a great safety record. Obviously, if not used correctly, any lawnmower can be dangerous but Bosch has done everything they can to make the Rotak 34R as safe as possible without reducing its effectiveness.

The lawnmower comes with a detailed and clear safety guide and provided you follow these instructions you will not have any problems.

They have also kept vibrations and noise at extremely good levels for a mower of this power.

It conforms to all the main local and international quality and safety standards.

Another safety feature they have built in is double insulation to prevent any risk of electrical shock under normal conditions and use. It also has a protector to prevent the motor from overheating. When it reaches a certain temperature, the motor will shut off. Only once it has cooled down to acceptable levels can it be used again.

To get the most from you Bosch Rotak 34R, ensure it is kept clean and well maintained. Use only Bosch approved replacement parts for best results and safety.

As with all corded lawnmowers, there is a safety button that needs to be held in in order for the starter grip to be activated. There is no additional removable safety key with the Bosch 34R as with all the Bosch cordless lawn mowers.


The Rotak 34R does not have mulching facilities. This is normal for lawnmowers in the price range and class.

What’s Included in the box?

Included in the box is the following:

  • 1 x Bosch Rotak 34R Lawnmower

  1. No Ergoflex handles – available on the Rotak 36R, Rotak 40 and 43 Rotak. Also available on the Bosch ARM 34.
  2. There is no grass box level indicator as with some of the other models.

While the positives far outweigh any negatives, as with any products, there is some downside. While we believe the price and easy manoeuvrability of the Rotak 34R make up for the minor negatives, it is important to be aware of them.

Although ideally designed and suited for use in small to medium gardens, some people might find the power cable, at 10 meters, to be a bit short. This can obviously easily be sorted out with an extension cord.

Another issue people with slightly larger gardens might have is that the 40-litre grass box will fill up rather quickly. All this means is that it will need to be emptied more often.

The blade size will mean it takes longer to cut large areas of lawn but the advantage is that it makes the mower more precise and easier to move.

Although the blade can be sharpened or replaced with ease, some customers might want a harder steel that lasts longer between sharpening or replacement.

Now the above may sound trivial and are common to most mowers but should be taken into consideration anyway. They are part of the package and it’s better being aware of them before a purchase than after.
