We have a Bosch Rotak in our summerhouse. The batteries and the mower might have been exposed to water. It starts okay, but stops after 1-2 sec’s. With both batteries. I’m in doubt if it’s the mower or the batteries causing the problem.
Mower starts to rotate slowly then up to speed but when stressed cutting grass slows down and often stops. why? The blade is OK and rotates freely (battery not connected!)
One of the back wheels keeps falling off. Just doesn’t seem to secure itself when put back on and just slides off. Do I need a new wheel? Any ideas pls.
Cant tell with out seeing it
I cannot start the mower with the right hand switches and now the left hand switches are playing up. Is this fixable?
these things are full of dry joints - locate the red key, cut the key out and solder wires together - you may have to go as far as pulling the motor out and cleaning up the contacts - dont worry its not as hard as it sounds
How do I get into the gubbins? It all looks inaccessible to me.
I have a Bosch Battery Lawnmower - purchased January 2020 The mower has worked really well until this week! The battery power pack (AL 3620 CV) has stopped functioning completely. Would this be a common problem? Would it be covered by a warranty?

Check that it is the battery pack. There is a know issue with the electronics in the mower failing. Please search for this information as many detailed articles have been posted. Not sure what the warranty covers and for how long.
Thank you. It does seem to be the battery pack as it does not respond at all ehen plugged in and turned on.
I have the above noted lawn mower and it has always worked rather well until recently. Now both batteries "pop" out while running. They are firmly inserted yet they continuously hop out. I have older batteries from many years ago and they appear to work just fine. Is this a sign that there is something wrong with the battery or with the connection?
I have exactly the same problem with my Rotak 36 Li. (single battery keeps popping out whilst mowing). Have tried “Bosch’s Ask a technician” but no help from that source. John B
I have the same problem. after a few minutes the battery slips out. I have tried everything , i think its a design flaw and I am not going to buy bosch anymore, since they havent aknowledged the issue
I have the same problem. I think it is just the lock/mechanism which is supposed to hold the battery in place that is worn. It is all plastic, so not sure there is an easy fix. I am considering some kind of hack, maybe strapping the battery in place, if I can find something to attach a strap to.
You probably need a new spring (stainless steel, not plastic). Springs get worn out, especially if you like me have an uneven lawn. No 43/10 in the diagram here external link . Spare part number for me was F 016 L66 108 (but I'm in another continent). Just remove the case (4 screws, torx bit or something like it, not ordinary 6-sided) and turn it carefully upside down (it's connected to the motor via wires, so no dragging!). You'll see the spring in the red plastic part.
Where are Bosch battery lawn mowers sold on Central coast NSW
Where I can buy with battery and charge? Thanks. Maria
EBay
My Bosch Rotak 43 has grass in air vent under mower. How do I I clean this out?
I have had a Bosch 43Li for 6 years now, it still starts up but cuts out again even with a full battery does anyone know a part that i can replace?
Sorry mate. I’m not expert in this. Try ringing the Service centre? Might not be worth fixing it though.
Sorry just seeing this post today. I had the same problem with my 43li. It used to cut out every 10 seconds or so because the isolator (safety) key was not engaging properly.I replaced the key but still no luck then it just stopped working alltogether. As a last resort I took it to my local lawnmower repair man and he was able to connect the isolator key, permanently into the body of the machine and it hasn't cut out once in the last 2 years! You just need to be more careful from a safety point of view. Unfortunately my charger stopped working today(hence I found this site) and they aren't repairable and are expensive to replace!
Ours had a wire come loose, it was fixed by a friend and still works fine
I have Sir Walter buffalo grass lawn.
Will the Bosch Rotak 43 Li mower handle this variety of grass easily?
It will but there's a cavete or two you need to think about. The longer you let it grow thus more you need to cut to get back to your chosen level will make things harder for it, so too long and it'll stall. In that situation you're better off taking the top off then cut again to your level. I've left it a few days in between cuts for those times where it's grown out of hand (ankle height).
More load then more battery used - or longer run time, more battery is needed. If I ran short then 30mins charge topped up to 80% and continued on. I think that only happened 4 times in over 5yrs when the wet season prevented mowing schedules. I used it on an old scratchy common buffalo grass that was terrible before softer buffalo grass was common. So Sir Walter buffalo should be easier than the punishment I gave the Rotak, it's just the density and length that might bite you (not forgetting area)
If you mow regularly it's not going to be a problem at all. Be aware it doesn't cut as low as you'd expect at some of the longer grass lengths. As it's lightweight it tends to sit on top of the grass till the catcher adds weight. None of the above was annoying when you consider how quiet it is and easy and manoeuvrable.
As Cobrin said. It really depends on the length you let the grass get too first. I have no issues with my unit handling my Sir Walter. But I keep it regularly mowed. I don't find the issue of weight in the catcher affecting the mowing height too bad. But the grass is pretty dense and very well thatched at the moment.
Can we use it as a corded mower if the battery fails?
No. However if you pulled it apart and managed to fit some sort of 230V AC motor it might be viable... Not recommended!
Where can i purchase the 43 Li in Perth?
I purchased mine from Amazon in Oz yo can check out external link
