Once bolts and blades have been removed, get your new blades and line them up with the base plate. The mower should spin anticlockwise and the blades should be placed in the direction shown in the video.
Make sure all bolts are firmly tight and that the blades will move when a decent force is applied. If the blades are locked too tight and you hit a rock, or another solid object, it can shear your flywheel key or shatter the con-rod in your engine causing major damage.
