Installation Instructions
Tine edges can be sharp and
can have slivers that could
cause personal injury. Use
care at all times when
handling tines. The tine hood
edges may also be sharp. To
prevent personal injury, wear
thick gloves when touching
the edges of the hood.
CAUTION
To prevent serious personal injury when removing or installing your bolo
tines:
• Stop the engine, and remove the electric start key (if your tiller features
electric start).
• Let the engine and muffler area cool.
• Disconnect the spark plug wire, and position the wire away from the plug
to prevent accidental starting.

A. Tine Inspection:
With use, the tines installed at the
factory will become shorter, narrower
and pointed. Badly worn tines will
result in a loss of tilling depth, and
reduced effectiveness when chopping
up and turning under organic matter.
B. Tine Removal and Installation:
1. With the engine shut off and the
spark plug wire disconnected, carefully
tilt the tiller forward until the engine is
resting on the ground. (On some
models it may be necessary to prop up
the rear of the tiller or to add additional
weight to the engine to stabilize the tiller
in this position.)
2. Raise the tiller hood flap and secure
it out of the way with a heavy rubber
band or string.
NOTE: Removing the tine holders from
the tine shaft may ease the installation
of your new bolo tines, but is not
necessarty. To do so, remove the screw
and nut which secure the tine holder to
the tine shaft, refer to Figure 2.
NOTE: Replace the inner tines (both
left-hand & right-hand) before
proceeding to the outer tines.
3. Use two 9/16-inch wrenches to
remove the two screws (A, Figure 2),
lockwashers (B) and nuts (C) that attach
a single tine to a tine holder. If needed,
use penetrating oil on the nuts.
4. Always discard old hardware and
tines. Use only the hardware which
came with your new tines.
5. When installing a replacement tine,
be sure to position it so that its cutting
edge (sharp) will enter the soil first as
the tiller moves forward.
6. Loosely fasten the new tine with the
screws, lockwashers and lock nuts
included in this kit. Refer to Figure 2.
7. In a clockwise fashion, replace the
remaining three tines in the gang-of-
four. Use two 9/16-inch wrenches to
securely tighten all four tines in place.
8. Proceed to the next four tines and
repeat the previous steps until all
sixteen bolo tines are replaced.

Bolt Removal Tips
❑Loosen all four nuts on a holder plate or tine gang before trying to remove any of the nuts and bolts.
❑If necessary, use penetrating oil to loosen stubborn nuts.
❑If necessary, place the closed (boxed) end of a wrench on the nut and sharply tap the wrench with the
rubber mallet until the nut is loose.
