6-42: Mark left and right holders.
A
WARNING
The tines or tine hood edges may
be sharp. Wear thick gloves to
protect your hands from cuts or
scrapes.
2. Before removing the holders,
use chalk to mark them “Left” and
“Right”, as shown in Photo 6-42.
This will help you later, when you
replace the holders.
3. Using a %-inch wrench, remove
the bolt, lockwasher and flat
washer that mounts the holder to
the tine shaft (Photo 6-43). If the
bolt is difficult to loosen, hold the
boxed end of the wrench on the
bolt and give the wrench a sharp
tap with a
soft mallet.
A
WARNING
Do not strike the wrench with a
metal tool. Doing so could cause
the wrench or tool to shatter,
resulting in flying metal frag­
ments that could injure your eyes.
Wear safety goggles to protect
your eyes.
4. Use a soft mallet to drive the
holder off the tine shaft. If neces­
sary, use a heavy hammer and a
long steel rod or hardwood board
placed against the back of the in­
side mounting plate to drive the
holder off.
A
WARNING
Wear safety goggles to protect
your eyes from flying metal or
wood fragments.
5. As you remove the holder, look
for a small, rectangular shaped
metal key (1" x 3/16") either in the
keyslot of the tine shaft or in the
keyway of the tine holder (Photo
6-44). Do not lose this key. It
should be securely installed in the
tine shaft by tapping it down gently
with a hammer (be careful not to
damage the edges of the key).
6. Clean off any dirt or debris from
the shaft and from inside the hold­
ers. Doing so will help to prevent
wear to the tine shaft and oil seals.
When cleaning, be careful not to
scratch or gouge the tine shaft or
the oil seals. Finally, apply a coat­
ing of grease to the tine shaft to
help prevent the holders from bind­
ing to the shaft.
Replacement steps:
1. When replacing the holders, al­
ways make certain that the cutting
edge of the tines are facing in the
direction of forward tiller travel.
Carefully align the keyway in the
hoider with the key in the tine shaft
and tap the holder into place with
a soft mallet.
2. Apply some grease to the
threads of the mounting bolt to
make removal easier the next time.

6-45: Replace mounting bolt.
3. Place the lockwasher on the
bolt, followed by the flat washer
(Photo 6-45). Tighten the bolt
securely.
Tine shaft maintenance
After every 10 operating hours,
you should remove the left and
right side Bolo Tine holders and
clean off any dirt, vines or straw
that may have accumulated on the
shaft or inside the holders. If left
unattended, this debris can cause
premature wear to the shaft and its
oil seals.
Refer to the previous tine holder
removal instructions for the proce­
dure to follow.
