MILL/BLOWER DRIVE
Belt Replacement
To replace the mill/blower drive belt, perform the following steps:
1. Disengage PTO, shut-off tractor and remove key.
2. Release front drive chain tension.
3. Loosen both of the bolt/nut (A & B) assemblies on the main
drive shaft.
4. After tension is released, remove the old belt and replace
with a new belt.
5. Adjust the new belt tension per the Adjustment Chapter of
this manual. After tension is properly adjusted, reconnect
the front drive chain idler bracket spring.
IMPORTANT:
The mill/blower drive belt will deteriorate more rapidly if improper tension is applied. Uneven
sheave alignment will result in uneven belt stretch. Improper mill/blower belt tension will produce excessive
pressure on the mill/blower bearings and cause premature bearing failure.

MILL HAMMER ROTATION OR REPLACEMENT
NOTE:
Use a catch pan or install a small screen below the rod for the hammers and spacers to drop into
as the rod is being pulled out.
IMPORTANT:
Hammers and spacers must be replaced in proper sequence with respect to the appropriate
row on the cylinder. When the hammers are rotated they should always be rotated in the same direction
to maintain a balanced cylinder. All 3 rows of hammers should be rotated at the same time or replaced at
the same time.
After the hammer rod is replaced and all of the hammers and spacers have been replaced, secure the rods
in place with a new 3/16 x 1-1/4” cotter pins. Spread the points and bend them around the rod. Replace
the access hole cover.
To maintain maximum grinding efficiency, the mill hammers
should be rotated before wear radius measures ¼” (6 mm).
Mill hammers are designed to be conveniently removed and
rotated through 4 positions, before they require replacement.
The hammers should be replaced when all four corners are
worn to ¼” (6 mm) radius.
The mill cylinder contains 3 rows with 22 hammers in each row.
To remove a row of hammers, rotate the cylinder to the position
where the row of hammers to be removed lines up with the
access hole in the left side of the mill housing. With the access
hole cover removed, pull the cotter pins out of the ends of the
hammer rod and pull the rod out through the access hole.
