Bosch Rotak Blade – Replacement
Problem with these Bosch mowers is that you can go nearly anywhere with them – which if you’re careless means you’ll soon be needing a replacement Bosch Rotak blade. Believe me these used to be extremely hard to find, but they are a little widely available now. Of course be careful, regularly sharpen and lubricate the blade and they should last many years but an encounter with a rockery at a 2000 rpm can leave a nasty dint in your mowers rotary blade.
Anyway I’ve checked a few places and the cheapest for these is now Amazon. So here’s a few links to where you can find a replacement Bosch Rotak Blade, I think I’ve found most of the main models. Just click on the images to check the price and availability.

Replacement Blade for the Bosch Rotak 40
Replacement blade for the Bosch Rotak 36
Replacement blade for the Bosch Rotak 34
They are all in the £10-£15 range, but if you find them any cheaper than above prices – please post a comment where they can be found.
If you have a battered and blunt Bosch Rotak blade in your mower then a replacement one does make mowing easier. But take care of them and remember to clear rocks and hard objects off the lawn beforehand and you should never need to buy a replacement Bosch blade !
If your blades aren’t damaged badly though – a metal file or sharpener will sort them though.
Bought a new blade for my Bosch Rotak 40 and you really do notice the difference. Cost me £15 from Amazon – much better finish now, mind you my blades were pretty damaged.
Hi I also brought a new blade, but I have tried and tried to remove old blade and can’t as blade turns at same time and bolt just won’t budge, I sprayed with WD40 but no luck, as I see you changed your bade can you offer any advise? cheers
Oops sorry Elizabeth missed your post. I just put my boot on the blade whilst turning the bolt – but sounds like yours may be a bit stiffer! Hope you got it sorted.
If Sfklady has not sorted her blade replacement problem, the normal resolution would be to use a ring spanner, secure the blade (with a gloved hand) and strike the far end of the spanner (in the blade rotation plane)with a small hammer. This should shock the the bolt free. Ths is also useful when re-bolting the replacement blade, but only one shock strike.
Hi I ran over a rock and badly bent blade, got a new one but like sfklady I cannot make bolt budge – wd40, ratchett the works and all I have managed to do is break tools! Any one have any ideas or advice on how to free the bolt thanks
Not certain how much this would cost in the stores but price seemed fair. Did have a little nervous instant because seemingly there two Rotak 40 versions and this blade does not fit both when it arrived. As such I tried to remove my old blade before opening the bundle to find out if I could hold up the old one against the brand new one to find out whether the profile was the same. Used to possess a Flymo hover that had a considerably bigger headed nut and requiring away this was a piece of cake. The blade is good although the Bosch layout so wasn’t perfect in my perspective.
The blade on my Rotak Ergoflex 40 needed replacing after 2 years given plenty of nicks from stones, cones, etc. Whilst the original blade was a good cutter, I was surprised at what a bad state it was in after just 2 seasons, with no cutting surface left at all (unsalvageable and hence straight to bin). When replacing the blade, the trick is to break the rust by scoring around the base of the old bolt with a sharp blade, and applying plenty of WD40 (even though Bosch says don’t !). A 13mm socket set and a power drill are also essentials. Check you tube for some good “how to” videos which will help.
