b) POWER TILLER with larger diameter L- blade rotor (fig. 56 and photo 57)
The blades can be fitted in two different ways, depending on the job to get done :
- 3 pairs of blades per flange
3 right blades (D) and 3 left blades (G) (as fitted at factory)
- 2 pairs of blades per flange
2 right blades (D) and 2 left blades (G)
To recognise if blades are right or left, point the cutting
edge in the direction of rotation (F) and note the
direction of their curved portion.
A = machine forward direction
To fit blades helicoidally, proceed as follows :
- Always start fitting each flange with a left blade,
placing it opposite mark (R), shown by a chamfer or
a hollow (see fig. 56),
- all blades should be fitted on the left face of the
flanges (see photo 57).
- Fixing bolt heads should face the blades, washers
and nuts should face the flanges.

End blades : depending on the way the blades have been fitted (2 or 3 pairs of blades per flange), the left end
flange is fitted with 2 right blades diametrically opposite to each other or 3 right blades. Likewise, the right end flange
