Thanks for that info mower man,
Movemet is the same with my one when the pedal is not engadged I can move the farside of the belt 50mm towards the jockey pulley.
Have move to box back 5mm tho it makes the drive chain a bit slack.
I was told some time back the belts were,
B76,for the Drive belt,
B58,for the cutting belt,
A33,for the clutch belt,
look at the new belt it is 13mm wide? well that be the reson why!
Got the old one out and she`s 10mm but it,s not going to live to long.
there`s some numbers stamped into the old belt 2385 used some chalk to bring them up
I,ll ring around after the new year for a new 10mm belt.
Thank you guys for all help.
I update this when I get the right size belt and the rideon`s working right
mower man, I think there robust mower too, Got two of them and one shell, The secon one has no motor or belt`s and need`s some bit`s here and there, Plan on latter getting and low HP motor in it for the kids to play in with.
