I've seen old belts that look like that, so I'm not conviced that you have any greater problem than an old worn drive-belt.  If a replacement shreds after a while, then you may have to look deeper into the issue, but for now, I'd just replace the belt and listen carefully for any noise of mis-aligned or loose pulley-wheels or bearings.

And if you take the belt to the parts counter of the repair shop, they will have seen enough old belts to be able to pass comment on whether it is typical wear, or if not, suggest likely causes/fixes.

Not sure if you are aware the mower is not much more than a year old, and being used domestically rather than commercially?

Unless it is a manufacturing fault (in which case you'd normally expect to see similar damage elsewhere on the belt, and is still not 'typical' wear) the damage sujsuj has got is not what you'd expect on a Mountfield mower of that age.  There are also friendly folks on the internet who have seen enough old belts to know - in conjunction with an idea of the belt's age and use - what is normal wear and tear.

A new belt won't be cheap, no point using one as a sacrificial fault detector when it is relatively easy to check the things that might cause premature belt failure.

The lack of any marking on the belt is also suspicious, particularly now we know the outside of the belt is complete with no bits missing.

Ok, now I'm scared.

Gonna have to start wearing a foil hat as that S62 can read minds and stuff :-(

Sujsuj, almost certainly the second part you mentioned in your first post. 135061423/0

And the dims on here would seem to confirm it: eBay 255047711187 (see dims at bottom)

Can be as cheap as eBay 265771121978

Or better quality?: https://www.beltingonline.com/mountfield-c-80_102_124_140/mountfield-1228hm-blade-belt-1350614230-p-13454.html

But check the blade spins freely, or S62 will track down where you live.

Easier to just read 'stuff' than it is minds....

Yeah, yeah. If you ain't reading minds, how come my head hurts whenever I see one of your posts?

It does however appear to have been somewhat abused by the OP.

Ah!  No I had missed the blade-sharpening and tennis-court-levelling threads!

I have just repaired my ex bosses ride on mountfield mower ,it is about 20 years old but still going ,on his you have to drop forward a lever to activate the mower part ,it tightens the belt which is designed to slip when driving but not mowing ,also there is a brake on the cutter head which stops the blade quickly to avoid damage ,might be worth checking the brake  ( if fitted ) is coming off.

Mountfield  Ride-on mower is 1.5 years old, but I believe I am doing very rough use. I think many times I let grass to grow too much then tried cut very short and all. Also cutting when grass is wet etc. I know I am using it very rough and not surprised with the state of this belt. I measured outer Circumference using thin metal wire. 

I managed to find suitable belt , fingers crossed. Once I have that I need to remove cutting deck and repair !
Any ideas how best I could do under deck repair for the mower..? I don't have any tool to lift the mower to work under it.
