Key Features

With any lawnmower, there are typically a number of key features, and we have shown those below.

Cutting Width

This is the width of grass that a mower can cut with one single pass. The width primarily determines the speed at which you can cut your grass at. The larger the width the quicker you can cut your grass, as you will have to do fewer passes. This model has a standard 34 cm cutting width, which is ideal for small to medium sized lawns.

Cutting Height

Most mowers will have a range of cutting heights. With the 34R model those are between 20-70 mm. (0.8 - 2.75"). The height is adjusted by moving a single lever into one of 5 different settings. Once the normal grass cutting starts, most gardeners will simply use the lowest setting for the rest of the cutting year. (March to October) The first cut is usually done on the highest setting (60mm) as the grass is longer. Trying to cut tall grass on the lowest setting will almost always clog up the underside of the mower, and especially if the grass is wet.

Grass Comb

The grass comb is an interesting and useful feature. It allows the mower to grab grass that is close to walls, paths etc, and also allows you to grab grass at the edges of lawns. This saves you having to cut along those with a strimmer or lawn edger or shears. It is fair to say the grass comb does a good enough job without being perfect.

Bosch Rotak 32R, vs 34R vs 36R

In this particular type of electric rotary range Bosch make two other models, called the Rotak 34R and the Rotak 36R. Just below we explain the key differences between those models. We have also provided links to reviews of those models.

Our Verdict on the Rotak 34R Model?

For a small to medium sized garden, this rotary mower is one of the biggest sellers on the UK market. It can handle grass that is about 3" in height, and is also good for general lawn mowing throughout the year. This is a good enough mower for a small to medium sized garden at an affordable price point. The mower is also light, easy to move around, and the mower is powerful enough to get the job done. 

This mower is good for use as adjusting the cutting height is easy, assembly is straightforward and even sharpening the blade is also pretty easy. We do however believe that the switch mechanism, and the associated lever is a bad design that can break. They are easy and cheap to replace, but still a poor design.

This compact 34R mower automatically cuts clean edges along flowerbeds, walls, and walkways. It is lightweight, easy to maneuver around objects and easy to store away and take out. It is suitable for mowing small- to medium-sized lawns and cutting tidy edges.

You can also buy replacement blades for this 34R model, and that is always a good thing to keep in mind. This is not a big powerful lawnmower, but it will allow you to quickly and easily mow your lawn, as long as you don't allow the grass to get too long.

Buyers also really liked that the front wheels help you get into awkward corners.


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.
