WARNING
To avoid serious injury or death:
Used tines can be very sharp. Always wear gloves when
handling tines to protect against cuts.
Inspect tiller tines (#2A to #2D) on all flanges (#4)
frequently for wear and loose shoulder bolts (#3). Tighten
loose shoulder bolts and replace tines that are worn out.
Tines that rotate primarily in one direction and still have a
good cutting edge on the opposite side and can be taken
off and turned around to increase that tine’s life.
Follow instructions for “Replacing Tiller Tines” below
when replacing used tines with new tines.
Follow instructions for “Reversing Tiller Tines” on the
right side of this page when turning used tines around.
Replacing Tiller Tines
Refer to Figure 5-3:
1. Remove one nylock nut (#1), shoulder bolt (#3), and
used tine (#2A).
2. Replace shoulder bolt (#3) if it shows any wear.
3. Attach new tine (#2A) to mounting flange (#4) making
certain it is positioned so that the bent end is oriented
in the same direction as the removed tine.
4. Replace 1/2"-13 shoulder bolt (#3) and hex nylock
nut (#1). Tighten nylock nut to the correct torque.

IMPORTANT: When ordering tines, be sure to order
genuine Kubota replacement tines only.
IMPORTANT: Remove and install one tine at a time
to ensure they are oriented correctly when installed.
5. Repeat steps 1-4 until all used tines have been
replaced with new tines.
Reversing Tiller Tines
Instructions for reversing tines are different depending on
whether tines are reversed only on some flanges or if all
the tines on the rotor are being reversed. Follow the set of
instructions below that apply.
Reverse All Tines on The Rotor
Refer to Figure 5-3:
1. Remove one nylock nut (#1), shoulder bolt (#3), and
tine (#2A).
2. Replace shoulder bolt (#3) if it shows any wear.
3. Rotate bent end of tine (#2A) 180
o
and reattach to
same slot in flange (#4). Make certain it is positioned
so that the bent end is oriented in the opposite
direction it was before removing it.
4. Replace 1/2"-13 shoulder bolt (#3) and nylock
nut (#1). Tighten nylock nut to the correct torque.
5. Repeat steps 1-4 until all tines on the rotor have been
replaced.
Reverse Tines on a Single Flange
Refer to Figure 5-3:
Always start with a tine that is oriented with the bent end
pointing in the same direction as tine (#2A) and work your
way around flange (#4) clockwise as follows:
1. Remove nylock nut (#1), shoulder bolt (#3), and
tine (#2A). Lay tine (#2A) aside as it will be the last
tine installed on flange (#4).
2. Replace shoulder bolt (#3) if it shows any wear.
3. Remove tine (#2B) and attach it where tine (#2A) was
with bent end oriented in the same direction as
removed tine (#2A). Tighten nylock nut (#1) to the
correct torque.
4. Remove tine (#2C) and attach it where tine (#2B) was
with bent end oriented in the same direction as
removed tine (#2B). Tighten nylock nut (#1) to the
correct torque.
5. Remove tine (#2D) and attach it where tine (#2C)
was with bent end oriented in the same direction as
removed tine (#2C). Tighten nylock nut (#1) to the
correct torque.
6. Attach tine (#2A) where tine (#2D) was with bent end
oriented in the same direction as removed tine (#2D).
Tighten nylock nut (#1) to the correct torque.
7. Repeat steps 1-6 for remaining flanges to be
reworked.
IMPORTANT: Remove and install one tine at a time
to ensure they are oriented correctly when installed.
IMPORTANT: Remove no more than two tines on a
flange to help ensure reversed tines are reinstalled
correctly.
