Hi Max,
Thanks for that, it is a mixed bag of options and always a guess as to what Rover used. One good thing is the motor is held on by 4 easy to get at bolts so the motor can be pulled off in a few minutes if the belt wears out. It has to be a material that is grippy to grab the drive wheel but hard enough not to wear too rapidly. My Daughters place in Drouin is flat and not too far away so that I can monitor it and for a free rideon mower they won't be able to complain much and I can see how the belt survives and you never know somebody may come here in the future asking for a solution to this problem These machines are so simple and it is a shame to see them going to scrap because of this simple drive disc problem
