Single Tine Replacement
1. Move the Wheels/Tines/PTO Drive
Lever to NEUTRAL, the Wheel Speed
Lever to either FAST or SLOW position,
and the Tines/PTO Clutch Lever to
ENGAGE.
2. Gently tilt the tiller forward until the
engine rests on the ground.
3. Raise the hood flap at the back of the
tiller and tie it up with string.
4. Before removing a tine, note in which
direction the bent tip points. The new tine
must be installed in the same direction.
5. Use two 9/16" wrenches to remove the
two bolts and nuts securing the tine to the
tine holder plate (Figure 5-32). Use pen-
etrating oil on the hardware if it is rusted or
hard to remove.
6. Mount the new tine exactly the way the
old tine was positioned. (The sharp edge
of the tine, which enters the soil first, must
face forward when above the tine shaft.)
Replace the bolts and nuts and tighten
them securely.
Removing and Replacing A Tine
Holder Assembly
The 16 Bolo Tines are mounted eight
per side on left-side and right-side tine
holders. Here’s how to replace the tines
and holders as assemblies.
Removing Tine Holder Assembly
1. Follow steps 1-through-3 in Single Tine
Replacement above.
2. Identify the tine holders as left-side
and right-side holders – they must be
replaced on the same side from which
they were removed. Use a piece of chalk
or a grease pencil to mark them L and R.
3. Remove the two bolts and nuts
securing each holder (Figure 5-33).
4. Use a soft mallet to drive the holder
off the tine shaft. (Use a heavy hammer
and block of wood to knock off the immo-
bilized tine holder.)
5. When the holder is off, clean all dirt
and debris from the shaft and the holder.
Apply fresh grease to the tine shaft.
Replacing Tines Holder Assembly
1. Replace the holder so the sharp tine
edges face forward (toward front of tiller).
Tap tine holder back on the tine shaft.
2. Grease the threads on the mounting
bolt(s). Install and tighten the bolt(s)
securely.
