Preparing Reel for Grinding
Three(3)typesofcutting reeldesignsareusedincutting
units for Reelmaster 5010- H machines: scalloped radi-
al reel, tapered radial reel and tapered forward swept
reel. The different types of individual reel blades are
shown in Figure 34. The radial reel designs have blades
that are placed in line with the center of the reel shaft.
The rear of the blades either have a scalloped relief or
atapered relief.The forwardswept reelhave bladesthat
havea slightforwardslant.The rearofthe forwardswept
reel blades have a tapered relief.
Before grinding a reel, make sure to identify the type of
reel design to make sure that grinding is correctly done.
NOTE: Beforegrinding acutting reel,make surethat all
cutting unit components are in good condition. Depend-
ing on type of grinder used, faulty cutting unit compo-
nents can affect grinding results.
NOTE: 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 (see Reel Grinding
Specifications chart below). Additional reel grinding in-
formation can be found in your Cutting Unit Operator’s
Manual and the Toro General Service Training Book,
Reel Mower Basics (part no. 09168SL).
After completing the reel grinding process, adjust cut-
ting unit (see Cutting Unit Operator’s Manual).

NOTE: Relief grind of cutting reel blades is necessary
when blade land width exceeds 0.120” (3 mm).
NOTE: After grinding the reel and/or bedknife, check
the reel to bedknife contact again after cutting two (2)
fairways. During this initial use, any burrs will be re-
movedfromreeland bedknifewhichmay createimprop-
er reel to bedknife clearance and thus accelerate wear.
This practice of re- checking the reel to bedknife contact
after grinding will extend the longevity of the sharpness
of the edge of the reel and the bedknife.
