Thanks all,
Mower is in mint condition, new knife, grind and lap at start of season.
Seems others of you have seen same issue!
These things come up so fast. Mow on a Sunday and come Tuesday they are around 50mm high.
In saying that it made me double check my mow height.
Dragged the Bonnar into the house onto the tiles (sorry wife) and used a metal ruler. I reckon I am mowing at about 9mm which surprised me.
As a newbie I need to ask. Is this normal? too high? too low? for healthy couch.
Cheers,
Tony
