ABSTRACT:
The present invention provides a lawn mower blade spindle assembly which can be easily serviced in the field, which includes a blade height adjustment feature which allows a blade to be replaced or be adjusted without removing the blade spindle bearings. An improved stress loading arrangement is further provided which reduces spindle stress and lessens the opportunity for spindle assembly failure upon catastrophic blade impact with an immovable object such as with a rock.
