If badly worn, they lose the ability to till deeply. Worn tines leave
an ever-increasing gap in the middle of a tilled row. The normal
gap is 3” between the tine tips — replace the tines when the gap
widens to 5”. See Fig. 7-8. The tines can be replaced individually
or as a complete set.
Replacing a Single Tine
WARNING! The tines or tine hooded edges may be
sharp . Wear thick gloves to protect your hands from
cuts or scrapes.
WARNING! Wear safety goggles to protect your
eyes . When loosening hardware, do not hit a
wrench with a metal tool. This could shatter the tool
or wrench sending metal particles into your eyes.
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.
Gently tilt the tiller forward until the engine rests on the
ground.
Raise the hood flap at the back of the tiller and tie it up
with string.
Before removing a tine, note in which direction the bent
tip points. The new tine must be installed in the same
direction.

Use two ⁄” wrenches to remove the two bolts and nuts
securing the tine to the tine holder plate. See Fig. 7-9. Use
penetrating oil on the hardware if it is rusted or hard to
remove.
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.
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.
Follow steps 1-3 in Single Tine Replacement above.
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.
Remove the two bolts and nuts securing each holder. See
Fig. 7-9.
Use a soft mallet to drive the holder off the tine shaft.
Use a heavy hammer and block of wood to knock off the
immobilized tine holder.
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
Replace the holder so the sharp tine edges face forward
(toward the front of the tiller). Tap tine holder back on the
tine shaft.
Grease the threads on the mounting bolt(s). Install and
tighten the bolt(s) securely.
