Before grinding a cutting reel, make sure that all the cutting unit components
are in good condition. Depending on the type of grinder used, faulty cutting
unit components can affect the grinding results. When grinding, be careful to
not overheat the cutting reel blades. Remove small amounts of material with
each pass of the grinder.
Follow reel grinder manufacturer's instructions to grind cutting reel to Toro
specifications; refer to
reel grinding information can be found in the Cutting Unit Operator's Manual.
An additional resource is the Toro Basics Series Training Book, Reel Mower

Relief grind the reel blades to the minimum blade land width if the reel blade land
width exceeds the service limit. Spin grind the reel to establish the specified
blade land width or to restore the reel's cylindrical shape.
Note: Always adjust the cutting unit after grinding the reel and/or bedknife; refer
to the Cutting Unit Operator's Manual. To extend the cutting unit performance
by allowing the reel and the bedknife to hold their edge longer, an additional
adjustment may be required after the first few minutes of operation as the reel
and bedknife conform to each other.
