Hi guys - I have a Flymo hover mower, only just over a year old. When I turn it on, the motor spins runs but it is not even attempting to spin the blade - the blade can move freely (I've checked for build up of grass) so it appears that the connection between motor and blade is broken.
Any ideas on how to fix this?

Don't they use a belt between motor and blade spindle to drive the blade .?? Maybe this company site will help if you havent seen it before .
Any possibility of telling us the model number? Is this problem mentioned in the user manual trouble-shooting section?
Every Flymo I have seen has the blade directly driven by the motor. Big bolt to hold it on and spacers to adjust the height.

>Thanks,
I've disassembled and found the broken belt - have ordered a new one from said website. Surprised it broke after so little time. Might have to post again when it comes to fitting the new one!!

Most of the newer ones have such weedy motors that they increase the torque by use of a toothed belt drive.

Universal motors (cheap, short life, ideal for making mowers into consumables) spin too fast for direct drive of a mower blade.
When I've looked at various friend's flymos, the motor usually disintegrates first (brush holder burning out seems common).
Andrew,
I have an early flymo from the 'Blue & white' era It has a direct drive from a big 1300 watt electrolux universal motor.
It is built like a brick proverbial. Years ago a dealer advised me to hang on to it as 'they don't make them like that any more'
It must be about 35 years old now and still going strong. Certainly not a 'consumable' design.

Hum, are you sure it's a universal motor?
Well, if they had continued making those, they would have gone out of business years ago;-) I had a Briggs and Stratton petrol mower which lasted 40 years (was my dad's originally), and when it finally died, it was the body which fell to bits -- the engine was still fine.
Better electric mowers use induction motors. The reasons are: o They don't wear out as fast (no brushes); o Their torque at different speeds is perfect for grass cutting (universal motors are the complete opposite); o Induction motors rotate at about the right speed for direct drive to the blades (speeds like 3,000RPM), whereas universal motors are normally much too fast (10,000RPM and more); o Induction motors tend to be more efficient, so you'll get away with a lower power induction motor on same size mower blade.
Last time I bought an electric mower (~6 years ago), I had to go to a lawn mower specialist to find induction motor mowers (and I don't think they stocked any flymos at all).
As a matter of interest, do you know who does make them?
Yup Series wound, brushes&commutator. The only deviation from a normal unversal motor is that it is fitted with a bridge rectifier at the mains input. I think this is because the field stack incorporates a moving section which acts as a brake on the armature. without the rectifier, I expect it would buzz at the line rate.

6 year old one is an Al-Ko Electrox (just had to go and see what is written on it). Instructions came in Dutch, Spanish, Polish, and Greek, but not English (and make no mention of Al-Ko Electrox, although the pictures are the same mower). I also bought one about 12 years ago which is with another member of the family now, and still working fine. That one is German and well designed/made, as well as slightly bigger, but I can't remember the make. ISTR it also had no English instructions. Looks like manufacturers don't expect to sell such mowers into the UK market.
Both of them came from the Sundon Lawnmower centre, Bedfordshire. I tried to get the same German one again second time around, but they said it got too expensive compared to other makes to keep in stock and would have to be ordered, which I couldn't be bothered to do.
It's a Lawnflite 282E, 16" cut, 1300W induction motor. Just used it, and it too is working fine.
Can domeone help ! I have a flymo chevron 34vc öwhich as stopped working . It seems that there is a buzxing from the motor but the blde dose not turn . Can someone advise me on the best course of action ?

When you say "the blade does not turn" do you mean it does not turn at all? Or just that it doesn't turn when you apply the power.
With the plug unplugged, check the blade turns by hand. It could be clogged with grass or a stone.
