looks nasty mate, I've had this with vinyl fixed with acrylic adhesive before, I hired a breaker as tall as me from Speedy hire which the nuts holding the blade kept coming loose, made me swear a lot, then eventually they all sheared off, so I then had to wait half a day for another one which lasted 30 mins and did exactly the same, so, I went to screwfix and bought some m10 25mm long nuts and bolts, put those on with extra nuts to lock the others, and job done, hard work though. When I took it back I told them what they needed to do :lol:
