14 Plow Assembly
If assembling an 8 1/2’ plow, remove end-
caps from compression springs and install
an extra spring inside each existing spring.
Place endcaps on springs and tighten 3/4”
lock nuts on pullrods until the outer springs
measure 13” long. Do not overtighten
springs.
3. Gently tip the plow assembly to its working
position with a hoist or forklift. Pin the park-
ing stand to hold the square tubes of the
push frame parallel to the ground.
DWG NO. 4201A
Swing the lift frame up to its approximate
working position and hold with a hoist or
forklift for assembly of the lift mechanism.
The bottom surface inside the two prong re-
ceiver channels should measure about 10
inches above the ground in the working po-
sition.
4. Locate a 90
O
O-ring/flare adapter in the
hardware bag from the parts box. Turn the
O-ring end into the port of the lift cylinder so
that the flare end is toward the rod end of
the cylinder when tightened.
DWG NO. 4202
Pin the base of the cylinder between the
center lugs of the lift frame with the 3/4” x
3” clevis pin provided. The hydraulic fitting
should be on the right side of the cylinder.
Remove four lift links and the stop plate kit
from the parts box. From the hardware bag
remove two 3/4 inch hex bolts, two 3/4 inch
I.D. shim washers and one 3/4 inch nylon
insert lock nut. Also remove the 1/2 inch
hex bolt and upper link spacer bushing.
DWG NO. 6585
Identify the RH and LH upper and lower
links by referring to drawing 6585. Assem-
ble the links with their stop surfaces away
from the lift cylinder.
Remove the 1/2 inch hex bolt and spacer
from between the tabs on the push frame.
Slide the stop plate onto the bolt, as shown
in the drawing, then bolt the two lower links
inside the tabs, with the spacer between the
links.
Assemble the two upper lift links outside the
lugs on the lift frame with a 3/4 inch x 4 1/4
inch hex bolt and nylon insert lock nut.
Bolt the upper link spacer bushing between
the two upper links with the 1/2 inch hex
bolt and lock nut.
Place the flat washer and spacer bushing
from the stop plate kit onto the remaining
3/4 inch hex bolt, then complete the lift
mechanism assembly by bolting the lift cyl-
inder rod, lower links and two shim washers
between the upper links.
