narrower and pointed. Badlyworn tines
will result in a loss of tilling depth and
reduced effectiveness when chopping up
and turning under organic matter.

plug wire disconnected, remove the two
screws (A, Figure 5-3) and Iocknuts (B)
that attach a single tine to the tine holder.

position it so that its cutting edge will
enter the soil first as the tiller moves
