check the mower performance.

ADJUSTING RAKE ANGLE OF 152CM ROTARY DECK __________________
If required, grass discharge can be improved by increasing the Rake Angle of the Cutter Deck. This can be
achieved by changing the Height of Cut pin hole position (Sect 9.3),down by one hole position whilst maintaining
all other HOC settings. This will effectively increase the discharge opening. You must not adjust by more than one
hole position for any given HOC range.
Example; If Deck is set in hole position 3 on HOC bracket H, The pin should be moved to hole position 4.
