Installation Instructions
C. Use two 9/16-inch wrenches
to remove the bolts which attach
the tines to the holders. (Tines
are not attached to cast iron
holders with bolts. In the case
of cast iron holders, remove
each gang [set of four tines]
from a holder by removing
only one bolt, and then
loosening the other three bolts
on the same gang.)
D. Always discard old hardware
and tines. Use only the
hardware which came with your
new tines.
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.

If You Ordered Custom
Tines...
Custom tines (special, hard-
faced tines which last up to 2-
1/2 times longer than stan-
dard tines) are perfect for
tilling sandy, gritty soil, or for
custom tilling or market gar-
dening.
If you received Custom
tines, read this General
Information and then follow
the standard tine installation
instructions which apply to
your particular model tiller.
If you have any difficulty
installing your Custom tines,
contact our Service
Department (Refer to the
back cover of this manual.)

Step 1: Check Your Parts
Remove the tines and hardware package and check that you received all of the parts listed below for your
model tiller. If any parts are missing or damaged, contact our Technical Service Department and we will arrange
for replacements.
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.
WARNING
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
Step 2: Tine Removal
A. 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.)
B. Raise the tiller hood flap and
secure it out of the way with a
rubber band, string or, in the case
of the PONY tiller, with the
depth regulator adjustment bar
knob.

Step 3: Tine Identification
Separate the sixteen new tines
into two groups: eight left-
curved tines and eight right-
curved tines. Tines can be
identified as either left-curved or
right-curved tines in two ways:

Figure 1: Look for "L" or "R" stamped on the tines.
Figure 4: Insertion of bolts.
Step 4: Bolt Installation
NOTE: Skip this step if you
have a HORSE Model tiller with
cast iron tine holders.
A. On all other models, place
the sixteen bolts through the
holes in the tine holders with the
threaded ends of the bolts
pointing outward toward each
side of the tiller as shown below
in Figure 4.
(The installation of
tines on holders is described
later in these instructions.)
Figure 3: Right-curved tine.
Figure 2: Left-curved tine.
B. Or, hold the tine with the
blunt edge toward you. If the tip
curves toward the left, the tine is
a left-curved tine. If the
tip
curves toward the right, the tine
is a right-curved tine. See
Figures 2 and 3 which show the
two types of tines.
A. The letters and numbers
stamped on the side of each tine
are factory code marks which
contain either an "L" (on left-
curved tines) or an "R" (on right-
curved tines). See Figure 1.

E. Add locknuts to the three
bolts and barely tighten the nuts
(just so they do not fall off the
bolts).
F. For future identification when
installing this gang on the
holder, use chalk or crayon to
mark the gang with a "B."
B. Rotate the gang so that the
the two innermost tines are
around one lug on the tine holder
and the other two tines are
around the other lug.
In the gangs just assembled, all
cutting edges are facing in one
direction. When installed on the
holders, these cutting edges must
enter the soil first when the tiller
is moving forward. Figure 19
shows the correct position on the
tine holders for the three "A"
gangs and the "B" gang.
Note that each holder shows a
letter which corresponds to the
"A" and "B" markings on the
tine gangs just assembled, and a
number which represents the
order in which the tine gangs are
installed on the holders.
A. Make sure that the tine bolts
are loose. Take one "A" gang
and wrap it around the tine
holder at position #1. Check that
the cutting edges are positioned
so that they will enter the soil
first when the tiller moves
forward.

following Steps A through C
above.
Step 5: Check the Installation
This completes the installation of the tines. To ensure that the installation is correct, check for the following:
Make sure that the tips of the four innermost tines (on the left and right sides) are directly opposite each
other and pointing toward each other. See Figure 20.
Make sure that the cutting edges of all tines will enter the soil first when the tiller is moving forward.
Also read and follow the instructions provided in the Bolo Tines Maintenance Section on Page 16.

Installation Tips
If you encounter difficulty in aligning the two holes when
inserting the fourth bolt, check the following:
Make sure that the bolts in the other three sets of holes are as
loose as possible.
Use a screwdriver inserted through the two empty holes to pry
the tines together.
Use a mallet to lightly tap the tines into the proper position.
If the holes still cannot be aligned, remove the tine gangs from
the holder, remove the holder from the tine shaft and examine
the holder for rough spots in the groove between the lugs.
Smooth any rough spots with a metal file and repeat Steps A
through C. Refer to your Owner/Operator Manual for holder
removal and replacement instructions.

in the following instructions.
ECONO HORSE Tiller owners should first follow Steps 1
and 2 of the instructions given on Page 12 for installing
tines on the PONY Model. Then, return to Step 1 below to
continue tine installation on your ECONO HORSE Model.
Step 1: Install Tines on Left
Outer Holder
Tines used in this step:
two right-curved tines
followed by
two left-curved tines
A. Place two right-curved tines
(shown shaded in Figure 24)
opposite each other on the
previously installed bolts. Make
sure that the tines are positioned
as follows:
Tines are across from each
other.
Tines are against the outer
surface of the left holder outer
plate.
Tips point inward toward
the transmission housing.
The cutting edges will enter
the soil first when the tiller
moves forward.
Figure 24: Installing tines on ECONO HORSE outer holders.
B. Place two left-curved tines
(unshaded in Figure 24) opposite
each other, overlapping the tines
positioned in Step 1-A. Make
sure that these tines are
positioned as follows:
Tines are across from each
other.
Tips point outward toward
the sides of the tiller.
The cutting edges will enter
the soil first when the tiller
moves forward.
C. Add lock washers and nuts to
all four bolts and tighten
securely.

A. Place two left-curved tines
(shown shaded in Figure 24)
opposite each other on the bolts
which were previously installed.
Make sure that the tines are
positioned as follows:
The tips of these two tines
should be directly opposite and
point toward the tips of the two
tines installed in Step 1-A. See
Figure 25.
Tines are across from each
other.
Step 2: Install Tines on Right
Outer Holder
Tines used in this step:
two left-curved tines
followed by
two right-curved tines.
Check the Installation
This completes the tine instal-
lation of tines on the ECONO
HORSE Model. To ensure that
the installation is correct, check
for the following:
Make sure that the tips of the
four innermost tines on the
outer holders are pointing
toward each other and
inward (toward the trans-
mission housing). See
Figure 25.
Make sure that the cutting
edges of all tines will enter
the soil first when the
tiller is moving forward.
Also read and follow the
instructions provided in the Bolo
Tines Maintenance Section on
Page 16.
Figure 25: ECONO HORSE tines installed.

BOLO TINES MAINTENANCE
Check Bolts and Nuts
Check all tine attachment bolts
and nuts for tightness every 10
hours of tiller operation.
Inspect Tines for Wear
Inspect tines after the first 10
to 15 hours of tiller operation
and then after every 10 hours.
See Figure 26.
Compare your tines to those
shown in Figure 26 to decide
whether your tines need
replacement. Your tines should
be replaced when the following
conditions occur:
Tines are worn beyond the
line shown in Figure 26.
Tines do not dig more than 3
to 5 inches and do not per-
form well for burying crop
residue and for sod busting.
Tines leave a wide, untilled
gap in the middle of a tilled
row, so that overlapping
becomes very time-
consuming.
Rotate HORSE and ECONO HORSE Tines for Longer Tine Life
HORSE and ECONO HORSE bolo tines can be rotated to obtain a
longer life. PONY tines are subject to equal wear because the tine
pattern is the same for all tines on a holder. Therefore, rotating tines
is not effective for that model.
Rotate tines once during their life cycle to increase tine life up to
40%.
Rotate tines to equalize wear among the tines.
Rotate tines before they wear beyond the line shown in Figure 26.

Step 1: Move the two left-
curved tines (labelled "A" in
Figure 28) from the left outer
holder to the "B" position on the
right outer holder. Move the two
left-curved tines which were at
the "B" position to "A."

Step 2: Move the two right-
curved tines
from position "C"
on the left inner holder to the
"
D" position on the right inner
holder. Move the two right-
curved tines which were at the
"
D" position to "C." See Figure

Step 3: Move the two left-
curved
tines from the "E"
position on the left inner holder
to the "
F" position on the right
inner holder. Move the two
left-
curved
tines which were at the
"
F" position to "E." See Figure
30.
Step 4: Move the two right-
curved
tines from position "G"
on the left outer holder to the
"
H" position on the right outer
holder. Move the two
right-
curved
tines which were at the
"
H" position to "G." See Figure
31.
