Fit the tractor lifting arms to
the lower linkage pins of the
Multi-Brush and secure with
the lynch pins.
Fit the special top-link sup-
plied with the brush. Ensure
the upper spring anchor is at
the tractor end of the top-link.
Raise the brush to transport
height using the tractor
hydraulics.
The flotation spring assembly
can now be easily fitted to the
upper spring anchor. Ensure
the ‘D’ shackle is tightened
securely.
Ensure the brush parking stands
are raised, then lower the brush
to the ground, and adjust the
upper link to ensure the brush
headstock is vertical. Open the
wing sections and adjust the
turnbuckle to obtain the required
flotation of the main frame.
If more flotation is required, and
there is no more adjustment on the
turnbuckle. Move the spring to a
lower position.
Note: Adjustment and repositioning
of the spring
must
be carried out
with the linkage raised and no
tension on the spring.
