OPERATING INSTRUCTIONS (Continued)
REEL DRIVE ADAPTERS
T
his grinder is equipped with an adapter that transfers the rotation from the spin drive gear box coupling to a
1/2" male square. To operate the grinder you need an adapter from this 1/2" male square to the reel shaft.
These adapters are NOT
included with this grinder.
Most cutting units In recent years have a male or female spline on the end of the reel shaft that connects to
a hydraulic or electric motor shaft.
If you have a reel shaft that has an internal threaded end which you can access, install a hex head bolt or
socket head screw of that thread size with a jam nut very tight so it does not loosen while spin grinding and
then drive with a 1/2" drive socket for that hex or hex key size.
JOHN DEERE REELS
COUPLERS- The external spline shafts use a female splined coupler between the reel shaft and the male
splined hydraulic motor shaft. The spline is either an 8,9 or 11 toothed spline. Our recommendation is to
purchase the female splined coupler from John Deere and weld it to a short 1/2" square socket extension.
Note: The 8 tooth spline adapter can be used with a Square Socket Drive Adapter [3/8" square male to 1/2"
square female] without welding.
REEL DIA
REEL TYPE Recomendation
5" G, M Has an 8-T, External shaft. Use coupler AET11038
7" H Has an 11-T, External shaft. Use coupler TCA12581
(NOTE: THIS CAN ALSO BE DRIVEN WITH A 1.25 HEX SOCKET)
7" 26H Has a 9-T, External shaft. Use coupler AET11310
(NOTE: THIS CAN ALSO BE DRIVEN WITH A 1.25 HEX SOCKET)
8" ESP Has a M16 X 2, External shaft. Use nut A31869 and drive with
a 24mm Hex Socket.
5" WBGM Use a 3/8"-24 UNF Bolt, and drive with a 9/16 Hex Socket
5" QA5 Has an 8-T, Internal Spline shaft. Use part AMT3022, to make
an adapter.
7" QA7 Has an 11-T, Internal Spline shaft. Use a 1.25 Hex Socket or
make and adapter from part TCA18958.
TORO EQUIPMENT:
Toro uses an 8 tooth female spline or a 9 tooth female spline on their reels. The 8 tooth female spline can be affectively
driven with a Square Socket Drive Adapter [3/8"square male to 1/2" square female]. The 9 tooth spline requires an
adapter. Our recommendation is to purchase adapter Toro tool part numberTOR-4074 available from
K-Line Industries, Inc. 315 Garden Ave. Holland, MI 49424.
JACOBSEN EQUIPMENT:
Below is a list of drive systems based on the cutting units:
* 5" reel units can be driven from the non hydraulic motor end of the reel. Install a 3/8" bolt in the end of the reel shaft
with a jam nut very tight so it does not loosen while spinning. Use a 9/16" socket to drive. They can also be driven from
the hydraulic motor end by pressing a Square Socket Drive Adapter [3/8" square male to 1/2" square female] into the
splined reel coupling Jacobsen part number 337370 and use this pressed assembly as the adapter.
* 7" reel units can be driven from either end. The reel unit has a coupler attached to the reel shaft a both ends. Purchase
Jacoben part number 4102440 Reel Motor Shaft and weld the hydraulic motor shaft form the kit to a 1/2" socket and use
this weldment as the adapter.
* Tri-King reel units can be driven on older pulley drive units with a 9/16" socket on the 3/8" bolt that holds the pulley. On
newer splined units, purchase the splined reel coupling Jacobsen part number 132002 and press a Square Socket Drive
Adater [3/8" square male to 1/2"square female] into the splined reel coupling and use this assembly as the adapter.
