A mower reel grinding apparatus for a plurality of types of mower units, the apparatus including a grinding wheel having a grinding wheel axis, and an enclosure including a table having a plurality of integral mounting channels. Each mounting channel is at a predetermined fixed position relative to the grinding wheel axis and each corresponds to at least one type of mower unit of the plurality of mower unit types, each mounting channel to receive a pivot element of one of the corresponding mower unit types such that when the pivot element is seated in the mounting channel a cutting reel of the mower unit is positioned at a desired position relative to the grinding wheel axis.

A device for sharpening lawnmower and sod cutting blades is provided. The blade sharpener provides a rotatable blade bed that can be used to safely adjust the grinding attack angle without exposing the operator to the moving grinding wheel. The blade bed of the present invention can be quickly adjusted over a range of different sharpening angles and is adapted for honing both right and left-sided blades.

A blade sharpener for use with a powered rotary tool having a rotatable sharpening element includes a main body having a bore for receiving the powered rotary tool, where the bore extends through the main body along an axis and the main body has a first channel for receiving a blade to be sharpened. The first channel is perpendicular to the rotary axis and opens into the bore to permit a blade to engage the sharpening element. The blade sharpener also includes a guide having a guide channel for receiving a blade to be sharpened where the guide is pivotally attached to the main body to accommodate any curvature of a blade to be sharpened as the blade sharpener follows along the blade.
