Tines
Before replacing tines make sure the tiller is firmly blocked.
The tines with which the rotary tiller is equipped can work soils of normal conformation. Check the degree
of wear and condition of the tines each day. If the blades should accidentally bend (or break) during work,
they must be immediately replaced.
First - Identify tines:
Remember to mount the new tine in exactly the same position as the old one (A). If several tines must be
replaced, it is advisable to remove and assemble one tine at a time in order to prevent positioning errors.
The tillers are normally equipped with 4 blades per flange.
