The reason for my enquiry was my ride on repair engineer said the Mountfield blade bolt was a D10 RH thread, I questioned this and said it was a LH thread as most blade rotations are anti clockwise so a Mountfield spares stockist would be (very) unlikely to get this wrong, in any event did the check, I had ordered from the manufacturer drawing and the part from their breakdown through a authorised stockist, mower not back yet so don’t know what he has done.
