center blade not cutting properly, lays the grass over,tried adjusting cutting deck by dropping the front &raising the rear & visa versa,removed blades & sharpened them still no joy,outer blades work fine,really annoying.
Did you buy it new ?
have you changed the deck belt.
A lot of owners fit the wrong belt ( too short ) which does not wrap around the centre ( front ) spindle but just glance across it without sufficient contact area to stop the belt slipping when the pulley is under any sort of load.

Is the blade on upside down? Is the under side of the deck clean?
