REEL DRIVE ADAPTERS
This 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.
Three adapters are included with this grinder. For a set please order part number 3706130.
Most cutting units manufactured 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. The three adpaters included are the most common splines used
on these reels.
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.
TORO EQUIPMENT:
Toro uses an 8 tooth female spline or a 9 tooth female spline on their reels. Adapters for both are included
with the grinder.
JOHN DEERE EQUIPMENT:
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 use it with one of the spline adapters included with this grinder.
If one of these adapters does not work, then we recommend this the coupler be welded 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.

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 the
supplied adapter.
* 7" reel units can be driven from either end. The reel unit has a coupler attached to the reel shaft at both
ends. Use the adapters supplied with the grinder.
* 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, use the adapters supplied with the grinder.
