There's meaning behind the madness of our model codes for our walk behind mower range from STIHL.
In this blog we'll help you better understand the meaning of the letters and numbers on walk behind mower models. The meanings behind the letters and numbers on the models vary quite significantly between manufacturers and we know it can get quite confusing, but we are here to help!
Our in depth, helpful guide below will make things clear and more obvious when choosing the right mower for you, so let's get started...
Let's talk about our STIHL mowers...
STIHL has a very similar size range of mowers to John Deere however their system is quite different in that they have 6 different series within the range with slightly varying features all the way through.
Firstly STIHL's number and lettering system differs quite significantly from John Deere’s so it is important not to mix the two. The letters at the start of a model number are the first identifying factor for STIHL as there are 3 variations which identify the type of mower. Firstly there is RM which means the mower is petrol operated, for example, the RM248. Next, there is RMA which means the mower is electrically operated, for example, the RMA235. Finally, there is RME which means the mower is battery operated, for example, the RME235.
Now we've got the letter understood you can then start to look through the STIHL range with a bit more confidence as to how the mowers are powered. STIHL cleverly separate their mowers into different series which is identified by the first number after the initial 2 letters (which tell us how it is powered), for example, the RM248 is a 2 series mower, the RM448 is a 4 series mower and the RM650 is a 6 series mower.
The next 2 numbers in the model number signify the width of the cutting deck, for example, the RM248 has a 48cm cutting deck. However it is important to remember this is not the cutting width but the width of the deck, the actual cutting with is 2cm narrower than this. For example, the RM248 has a 48cm wide deck and a 46cm wide cutting width - got it?.
Okay so, the final part of the model number does work the same way as the John Deere system in that it identifies the significant features of that machine, however they do use different letters and meanings. For example, T stands for self-propelled single speed so the RM248T would be a petrol mower in the 2 series with a 48cm wide deck that is self-propelled at a single speed.
Each of the series has several different variations with different features so as before we have provided you with a handy table to help explain these features according to the model number. As far as the differences between series go there are many, it works on a scale so the 2 series is the lowest/cheapest with the smallest amount of features, for example, steel decks and small collection boxes. On the opposite end of the scale, the 6/7 series, which are the most expensive, have more features such as aluminum decks and larger collection boxes.
