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.
Second - Install New Tines:
1. Raise tiller with a safe lifting device.
1. Put safety stands or blocks under tiller.
3. Stand facing rear of tiller and study placement of tines.
4. Remove four bolts, lock washers, and nuts (C).
