Hayter drive belt 56cm deck.

[Gregs mowing]

So I've worked on the new Toro Prostripe and Hayter 56 pro. obviously same deck and cut but one thing I can't work out is how are you supposed to change the large drive belt?
It spins off the crank then onto a twin pulley. Can't work out an easy way to get the belt off without taking all the BBC stuff off, I did take the disc holder off (hold on by 2x14mm nuts) but the pulley with bearings wouldn't come off - any tools needed?

Any advice much appreciated.

Don't think I've had to actually change one of the drive belts yet, other than the bbc one. I would probably just remove the clutch to check it, and change the belt at the same time if required.

Is your belt worn then Greg?
