Flailhead Attachment - McConnel PA50 Mk3 Operator's Manual

FLAILHEAD ATTACHMENT

For ease of attachment and safety this procedure is best performed on a firm level site.
With the tractor parked alongside the flailhead operate the controls of the machine to
position the pivot bracket of the machines head angling mechanism directly behind
flailhead with the base of the hose tray (or junction bracket) parallel to the ground.
Manoeuvre the flailhead backwards on its roller until the heads attachment bracket is
adjacent to the machines pivot bracket. Fit the 4 attachment bolts through the brackets
from the arm side - if the holes are mis-aligned carefully operate the angling ram until the
holes correspond.
WARNING: Ensure all persons remain at a safe distance whilst operating the angling
function as the geometry of the head angling mechanism produces several pinch risk areas.
With the attachment bolts correctly located through the brackets fit the self-locking nuts
and tighten alternately until the brackets are drawn flush before finally tightening them to a
torque setting of 203Nm (150ft.lbs).
Flailhead Hose Attachment
With the flailhead attached to the
machine the hydraulic hoses can
now be connected – refer to
diagrams opposite. Upper port 'A'
on the motor connects to junction
bracket point 'A' on the arm and
lower port 'B' on the motor
connects to junction bracket point
'B' on the arm.
Note: If a hose tray is already
fitted to the arm it will need to be
removed to allow the hoses to
be connected to the junction
bracket – ensure the hose tray is
replaced once the hoses have
been connected.
