[@eynshamyman3403]

Thankyou Rich for uploading this video, My belt snaped Too, the shaft bearing at the blade end was seized, I managed to free it up, and gave it a good clean and re-lubricated. You helped Save me from buying new mower.

[@RichDavey]

Thanks Eynshamy. My video is not the best but it shows these things can be be repaired with a bit of time and patience.

[@S.78614]

Thanks for this video. You have just showed us how to completely recondition this lawnmower I have similar issues with mine I will check on/off switch first. Then follow your instructions Good educational video

[@RichDavey]

Hi Saeed Many thanks for your comment My video is far from perfect but I am glad it’s helped you get running again 😊

[@y0rkiebar]

Nice one, I've got a Rotak 40 purchased in 2007 which is still going strong. Good to know that if it develops a minor fault like this then it can be fixed easily.

[@RichDavey]

Yes Yorkiebar it can fixed with a little time and effort

[@Commonsensenotsocommon]

Thank you! We had exactly the same problem. I was just about to get a new lawnmower when I found this vid. Ordered a new belt instead and saved over £100

[@RichDavey]

Glad to hear that Mag It’s not the clearest of videos but my aim is to advise to repair if you can. All the best

[@parky71]

cheers for this pal. mine just burnt out a belt i think. i was doing some grass for someone and it was rather long. i didn't see a beer can in the long grass lol and it got jammed in the blade, i could smell burning rubber. i gave it 10 mins and tried it again. motor seems fine but the blade shaft dont turn. so i'm just striping mine down now. this video came in handy for me. nice one!

[@parky71]

yip it was the belt. just ordered one. pleased about that as it wasn't an old mower.

[@RichDavey]

Hi Parky Great to hear this video has helped you You will be back in business in no time Well done 👍

[@parky71]

@@RichDavey was ok to get apart but there had to be 1 rusty screw head . it was the last one i had to get out! . sods law mate lol. the single 1 on its own underneath. had to drill the head off but then i managed to get the rest out.

[@Azerty72200]

Thanks a lot for the video, we were stuck trying to detach the big green cover but we didn't know how to detach the motor beforehand.

Glad my video helped you Azerty 👍😊

Lightweight is good and what did I use it for it’s a lawnmower kzbin.infoUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one. But if you take care it does the job really well.

[@RichDavey]

Glad it helped you a little 👍

[@RichDavey]

Well done Parky Perseverance always pays off mate 😊

[@mysticmarkthemagician5852]

I cant than you enough just the help I needed

[@RichDavey]

Haha your welcome Mark Glad it helped you out It was worth doing the video then 👍😊

[@JohnJohn-gn2ey]

And just like magic the belt is on!

[@RichDavey]

Yes John it did take a bit of getting on but it’s worth the time stripping down. Thanks for the comment

[@faroyoussef1757]

You didn’t show us how to put the belt.

[@rogertaylor7493]

Hi Rich. My Rotak stopped working on Sunday so I found and followed your excellent instructions to dismantle. I thought the problem was that the belt appeared to be jammed (rather than broken) but have now discovered that the motor itself appears to be seized up. Do you have any idea if this fixable, or should I try to find a new motor, please. Mine is a Rotak 40 GC, probably about 18 years old so doesn't owe me anything

[@zyme4569]

I have the exact same model. Mine appears to have seized up as well. I can hear the click and the motor trying to move but the blade is completely jammed. I haven't taken it apart yet though

[@ronyoung9234]

Bosh

[@RichDavey]

@@zyme4569 Hi Zyme Thanks for the kind words Did you get yours running again? Sorry for the long delay

[@zyme4569]

@@RichDavey no couldn't figure it out so just ripped the motor out to add to my scrap copper and the rest. I had another mower so I didn't need it and it was old anyway

[@RichDavey]

@@zyme4569 ah at least you will get something for the scrap copper. All the best

[@f-22r]

How do you get the red semi-circular handles to work? I inherited this mower and it only had one handle. I ordered another one, but already the plastic on the handle has become bent with tightening. It means the frame won't stay up.

[@RichDavey]

Can it be straightened?

[@f-22r]

@@RichDavey depends what you mean. What I meant is that the plastic on the handle has become deformed by tightening it so that the frame will stay up; otherwise it just sags.

[@rst570]

Same mower same problem thx 👍

[@RichDavey]

Hope the video helped you

[@babyjitchorlie9711]

Where did you get the belt from? As my lawnmower is the same as the one you was showing.

Hi, put the details in Google and bought on a website

lovely mower, i need help as i was mowing my lawn the cord was mistaken cut off and i have fixed the cord together but the mower wont turn on, any tips as to what to do to make it work again, i am quarter done with the lawn

Hi Adeniyi, fuse to be checked in plug. Thanks

[@RichDavey]

@@adeniyigaruba8487 you can’t tell by looking at the fuse. Try the fuse in another device to see if it works

[@RichDavey]

Check your connection on the repair. Power off obviously while checking

[@RichDavey]

Hi Roger, thanks for your kind words. Can you spin the motor by hand? Check the brushes, basically where power connects to the motor. These can be removed and replaced. All the best

[@ridhimaranga7740]

Can’t fix the belt 🙈 any trick to do that??

[@sandieb2019]

Hi Roger, I got mine not long ago. My lawn was really long and my daughter went straight into the thickest part of the lawn to cut. Mower stopped as it couldn't cope with the height of the grass. I've removed the grass but now it won't start at all. Any ideas if there's a reset button or some other fixable reason why it hasn't started. Thanks

[@RichDavey]

I guess you have checked the fuse?

[@sandieb2019]

@@RichDavey Ha! So I have changed the fuse now but I've hit another hurdle. Mower started and the blade goes round when its not in contact with the grass, but its not cutting the grass. Its set on the highest level, but it should still be cutting something as the grass is still moderately high 🙁

[@RichDavey]

Once you have the height set correctly you will be fine.

[@shima.polo.Traveler]

Hi! Mine has the same issue! Where did you get the belt from? Thanks.

[@RichDavey]

Hi Shima, just put the model number in google and you will locate a supplier. Mine was approximately £10 not cheap but better than cost of a new mower 👍 good luck

[@christopherwheeler688]

I would really like to know the purpose of the carbon brush that rubs against the iron ring in the driven pulley. It must have a function but, as it isn't electrically connected to anything else, it seems to serve no purpose. My mower runs for a second then switches off in spite of replacing the thermal fuse and switch and lubricating the bearings.

[@RichDavey]

Hi Christopher The carbon brushes drive the motor. Replace if the no longer have any carbon left on them.

[@christopherwheeler688]

@@RichDavey Wow! Thanks for the reply which I didn't expect at all. I do understand the two brushes on the motor commutator, it's the one that sits in the bottom half of the casing and pushes upwards onto the driven pully I don't get. It seems electrically isolated from everything so why is it there and what does it do? If you can shed any light I would be doubly grateful.

[@RichDavey]

@@christopherwheeler688 Hi Christopher It is a while since I had that mower apart to be truthful. I am thinking maybe it’s an option that is active on different models. Be patient and am sure an answer will be forthcoming. All the best. Rich

[@StreamingCamel]

Could it be a grounding connector for the iron ring?

[@kevinmitchell4960]

Is the blade bolt left hand thread?

[@RichDavey]

Hi Kevin If I am honest I cannot remember which way the rotor turned The bolt will tighten the opposite way to which way the rotor turns

[@TheKinith]

Hi, how do you remove the positioning lever handle? Mine has snapped off and I need to replace it but the remanants of the old one are very hard to get off with a screwdriver.

[@RichDavey]

Hi Alan, I thought the position bar unclipped. I no longer have the mower. Someone on here will answer your question I guess

[@LSP_GROUP]

Hi Rich, what is the spring part and how do we reattach it once it’s been removed?

[@RichDavey]

Hi George, I assume you must be talking about the spring to keep tension on the door are you?

[@LSP_GROUP]

Hi Rich, it's the spring that attaches itself on the white cap (through a small metal bar). Not sure where the other end is meant to be attached? (what is the door you're referring to?)

[@RichDavey]

@@LSP_GROUP Hi George, the door I refer to is where the grass cuttings leave the mower into the cuttings box. I no longer have the mower to refer to

[@01scarab]

Shame you didn’t actually show how to fit the broken belt!

[@RichDavey]

The video does show that the Rotak can be taken apart and repaired. Apologies if you didn’t enjoy watching it.

[@SpacedOdyssey]

I would have spun it up to check that it worked before final assembly

[@RichDavey]

Thanks for the comment. If ever I repair one I will remember that 👍😊

@Rich Davey nah dude, it's all good. The fact I was sat on my patio following your lead step by step with a wife pi**ed off at our long grass stood watching didn't help my mood lol. Gave me an excuse to give up and have a beer anyway🤣

[@darryladams4511]

Notice that you didn't show any detail when it came to the trickiest part of the job - fitting the belt and reinserting the motor assembly into the bearing. Bit of a cop out.

[@RichDavey]

Thanks for your comment Darryl. I don’t pretend to be an horticultural engineer. Far from it. While undertaking such jobs I don’t want to be putting the tools down to film. I got the new belt on and got the mower going again. All the best to you 👍

[@marka9898]

Completely agree! I fixed several Rotaks and this video is very misleading. There is no need to take the lower housing off for this job which becomes obvious when reassembling (but video fails to mention) and he re-connected the motor housing before assembling the lower body cover - which is a no-no as it makes assembly much more tricky. This Video just makes a meal of a simple fix and is not a helpful guide.

[@RichDavey]

@@marka9898 thanks for your the comments Mark. As I have said I am not an expert at repairing grass cutters. Hopefully someone will get something out of the video. It’s far better to repair than just dump these.

[@PamelaWhiting-uo7dw]

I can see why you didn’t show how to replace the belt, my husband spent all day yesterday trying to get the cog back into the housing after attaching the belt and no way would it stretch to drop back into the housing.section. Very disappointing video .

[@RichDavey]

My videos are not the best Pamela I don’t claim them to be Any information gained from watching a video has to be better than what I had before dismantling the grass cutter Thanks for watching

[@margaretevans6813]

Wheels are not that easy to adjust height would be better adjusted with a lever.

[@RichDavey]

Quite agree Margaret. I don’t have this machine anymore. It was a repair and sell. I like my Honda but they are not the cheapest. Easy to adjust height.
