Hi Barryjnr, and nice to see you back on the forum.
My advice is to
not use your Scott Bonnar 45 on lawn that has been top-dressed with loam that contains
sand. This would be like feeding sandpaper in between the reel and bedknife and blunting it immediately.
You will have to get the reel and bedknife sharpened again to achieve a satisfactory finish, and not use it where sand is present
