Hayter Mowers Harrier 41 412E - Manual (Page 17)

To prevent engine damage do not use the mower on slopes greater
than 20 degrees.
Move the height of cut lever sideways to disengage it from the locking
notch, then push forwards to lower or pull backwards to raise the height
of cut. Release the lever in the required position and ensure that it locks
firmly into one of the seven notch settings.
Always select a height of cut to suit operating conditions. Prevent
engine overloading and blockages by avoiding low cuts in long grass
conditions. Be prepared to make two cuts when the grass is long.
