When the Wheel Gear Lever is in
DISENGAGE, the wheels will roll
freely (freewheel). The wheels
should not roll freely when the lever
is in ENGAGE. If the wheels roll
freely when the Wheel Gear Lever is
in ENGAGE, the wheel gear cable
needs to be adjusted as described
below.
1, With the engine shut off and the
spark.plug wire disconnected, put
the Wheel Gear Lever in ENGAGE.
2. Loosen the top adjustment nut (A,
Figure 4-7) on the wheel gear cable
bracket that is located on the left
side rear of the transmission.
3. Push the wheel gear cable (B)
down and roll the tiller slightly for-
ward or backward until the eccentric
lever (C) engages (locks) the
wheels. Hold the cable in that posi-
tion and tighten the top (A) and bot-
tom (D) adjustment nuts.
4. Move the Wheel Gear Lever to
ENGAGE and DISENGAGE several
times to check the adjustment. The
wheels should not roll when the lever
is in ENGAGE, but they should roll
when the lever is in DISENGAGE.
Readjust the cable as required.

The tines will wear with use and
should be inspected at the beginning
of each tilling season and after every
30 operating hours. Tines can be re-
placed individually or as a complete
set. Never inspect or service the
tines unless the engine is stopped
and the spark plug wire is discon-
nected.
NOTE: You must first remove the
tiller hood in order to take offeither a
single tine holder or individual tines.
The hood is secured to the transmis-
sion housing with two rear bolts and
two front bolts. Remove all four
bolts and set the hood aside to have
full access to the tines.
Tine Inspection
With use, the tines (Figure 4-8) will
become shorter, narrower and point-
ed. Badly worn tines will result in a
loss of tilling depth and reduced ef-
fectiveness when chopping up and
turning under organic matter.
Figure4-8:Checktinesforwearafterevery
30 operatinghours.
1. Use a 9/16" socket, 6" extension,
a ratchet, and a 9/16" box wrench to
loosen the nut (A, Figure 4-9) and
bolt (B) that secure the tine holder to
the tine shaft.
2. Use a rubber mallet to tap the tine
holder loose.
3. Slide the tine assembly offthe tine
shaft.
4. RePeat Steps 1-through-3 abo..ve
to remove the other tine assembly.
5. Installing the tine assembly is sim-
ply the reverse of its removal. Be
sure the cutting edges face so they
will enter the soil first when the tiller
is moving forward- this means the
cutting edges face toward the opera-
tor position.
First be sure to remove any rust, un-
even spots or burrs from the tine
shaft, using fine sandpaper. Then
grease the tine shaft before rein-
stalling the tine assemblies. Tighten
the hardware very securely.
Removingand Installing
IndividualTines
1. Use two 9/16" box end wrenches
to remove the two bolts (C, Figure
4-9), and nuts (D) that secure the
tine to its tine holder. See Figure 4-9.
NOTE: If the nuts are rusted, apply
penetrating oil to the bolt and nut.
Let the oil soak in for a few minutes
before loosening the nut. Always
loosen the nut rather than the bolt.
2. When installing individual tines, in-
stall them in the reverse order from
which they were removed. The two
sets of inboard tines are installed so
one set faces toward the transmis-
sion housing and the other faces
away from it. The single outboard,.
tine set faces toward the transmis-
sion housing. Also be sure the cut-
ting edges face so they will enter the
soil first when the tiller is moving for-
ward- this means the cutting edges
face toward the operator position.
