How do I change the tines
You have not shared which model and make of tiller you have, but many of them have a set screw or two holding each tine on.
You would need to loosen the screws, and maybe polish the shaft with sandpaper and oil it to get each tine off in order.
Some tillers use a different method of tine installation, since this can be patented or trademarked.
For example, some have the tines permanently attached to the shaft, so the whole shaft must be replaced as a unit.
God bless your efforts.
