7. Replace the old belts with the new belts in the same order
they were removed. The longer belt (754-04091) belongs
closer to the engine, with the shorter belt (754-04090)
positioned closer to the tines.
8. Reinstall the transmission drive pulley with the new belts.
9. Reassemble the tiller in the reverse order in which it was
disassembled.
NOTE:When reinstalling the belt cover, be sure to engage the
bail and hold it so that the drive belt is tight before attempting to
reinstall the belt cover. This will enable the belt to fall under the
belt keeping mechanism built into the belt cover. Failure to do so
could damage the belt and/or belt cover.
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 Replacement Parts
section for part numbers and ordering instructions.
TineInspection
With use, the tines will become shorter, narrower and pointed.
Badly worn tines will result in a loss of tilling depth, and reduced
effectiveness when chopping up and turning under organic matter.

Remove the tine shield end covers and side shields (If so
equipped) by removing the three wing nuts on each side
that secure them.
A tine assembly consists of a left hand tine assembly and a
right hand tine assembly.
NOTE:The tine assembly moves in a counter-rotating
motion with the sharp edges of the tines positioned to
enter the soil first when counter-rotating. Note this position
of the tines for reinstallation of the new tine assemblies.
To remove a tine assembly, simply remove the bow-tie
cotter pin securing the clevis pin. Remove the clevis pin
and slide the assembly to the outside of the tiller and off of
the tine shaft.
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.
Install each tine assembly so that the cutting (sharp) edge
of the tines will enter the soil first when the tiller moves
forward. Keep in mind that these tines are counter rotating
so Secure the tine assembly to the tine shaft using the
clevis pin and internal cotter pin.
