BELT REPLACEMENT
WARNING
Before performing any type of maintenance on the machine, wait for
all parts to stop moving and disconnect the spark plug wire. Failure
to follow this instruction could result in personal injury or property
damage.
If the drive belt needs to be replaced, make sure you use only a factory
authorized belt listed in the Parts pages of this operator's manual, as an
"over- the-counter" belt may not perform satisfactorily. The procedure
requires average mechanical ability and commonly available tools.
To replace the Drive belt, follow these steps:
1. Remove the belt cover from the left side of the tiller by removing the
two self tapping screws and hex stop nut and washer. See Figure 26.
2. Remove the idler pulley bolt and move the belt from under the
idler pulley keeper. See Figure 27.

3. Remove the belt keeper assembly located behind the engine
pulley by removing the two hex bolts and lock washers. See
Figure 27.
4. Remove the old belt from around the transmission pulley and
install the new belt. See Figure 27.
5. Follow the instructions in reverse order to re-install the belt keeper
and idler pulley.
NOTE: Upon reassembly, make certain that the idler pulley keeper is as
shown in Figure 27. Take note of the notch on the bottom of the keeper
and the alignment when reassembling with the replacement belt.
NOTE; After re-installing the belt, double-check the cable adjustment.
Refer to the Assembly section for instructions on adjusting the cable.
TINES
The tines will wear with use and should be inspected at the beginning
of each tilling season and after every 30 operating hours. The tines
can be replaced. Refer to the Parts List section of this manual for part
numbers.
Tine Inspection
With use, the tines will become shorter, narrower and pointed. Badly
worn tines will result in a loss of tilling depth, and reduced effective-
ness when chopping up and turning under organic matter.
Removing/Installing a Tine Assembly
Nut
1. A tine assembly consists of a left hand tine and a right hand tine.
NOTE: The sharp edges of the tines are positioned to enter the soil
first when rotating. Note this position of the tines for reinstallation of the
new tine assemblies.
2. To remove a tine assembly, simply remove the cotter pin securing
the clevis pin for each tine. See Figure 28.
Cotter Pin
3. Remove the clevis pin for each tine, and slide the assembly to the
outside of the unit and off of the tine shaft.
4. Before reinstalling the tine assembly, inspect the tine shaft for
rust, rough spots or burrs. Lightly file or sand, as needed. Apply a
thin coat of grease to the shaft.
5. Install each tine of the assembly so that the cutting (sharp) edge
of the tines will enter the soil first when the tiller moves forward.
