Plow Assembly
2.
Open the frame crate and set aside the
power unit box, headlamp boxes and parts
box for later. Carefully lift the frame assem-
bly from the crate by wrapping hoist straps
or padded chains around both ends of the
2 1/2 inch square tube at the back of the
frame assembly.
Remove the 3/4 inch hex bolt, arrow 1 in
drawing 5420A, and two 1/2 inch hex bolts,
and spacers, arrow 2, from the push frame.
Align the push frame hitch plates with the
pivot hole in the moldboard tube, then re-
assemble the 3/4 inch hex bolt, slotted nut
and cotter pin. Install the nut so that the as-
sembly is secure, but frames will pivot.
Reassemble the two 1/2 inch hex bolts,
spacers and lock nuts at their original loca-
tions and fully tighten hardware.
Remove clevis pins from the rod ends of the
two angling cylinders. Loosen the plugs in
the cylinder ports and extend the cylinder
rods to the lugs on the back of the mold-
board. Pin the rods between the lugs with
the clevis pins and cotter pins.

4.
Tip the moldboard and frame assembly to
their working position with a hoist or fork
truck. Pin the parking stand to hold the
square tubes of the push frame parallel to
the ground.
Swing the lift frame to its approximate work-
ing position and hold it with a hoist or forklift
for assembly of the lift mechanism.
The bottom surface inside the two prong
receiver channels should measure approxi-
mately 10 inches above the ground in the
working position.
Locate a 90
O-ring/flare adapter in the
hardware bag and the lift cylinder from the
parts box. Turn the O-ring end into the port
of the lift cylinder so that the flare end points
toward the rod end and is directed up about
20 from the cylinder centerline to provide
clearance for installing the hose later.
