Allied by Farm King has years of snowblower manufacturing expertise. Thousands of acreages,
farms, and cities depend on Allied by Farm King snowblowers. PTO-driven Allied by Farm King
Snowblowers attach to 3-point hitch. This snowblower is supplied with category 2 pins with
conversion bushings to category 3 available. Adjustable cup type skid shoes are standard on all
models.
Four blade fans are standard on all models. Shear bolt protection is provided at the sprocket
to the main auger, and is easily accessed by removing wing nuts and cover at the back of
the housing. A hitch system, which is quick-hitch compatible, is standard on all models. Also
available is an optional hydraulic spout deflector.
The 96" is for tractors from 90 hp to 125 hp. It has a 540-rpm oil bath gearbox with #60 chain.
The chute rotation is hydraulic (cylinder and necessary hardware not included). An optional
hand crank kit is available for chute rotation. Hydraulic spout deflector kits are available. There
is a shear bolt on the auger and on the PTO shaft to protect the machine from damage if a large
object is picked up. Any smaller objects in the snow will be thrown with it and could cause
serious injury. Do not allow anyone to stand behind the tractor or in the area of the discharged
snow.
Keep this manual handy for frequent reference. All new operators or owners must review the
manual before using the equipment and at least annually thereafter. Contact your Allied by Farm
King Dealer if you need assistance, information, or additional copies of the manual. Visit our
website at www.farm-king.com for a complete list of dealers in your area.

Installation of Safety Signs
To install safety signs, ensure the installation area is clean and dry. Decide on the exact position
before you remove the backing paper. Remove the smallest portion of the split backing paper and
align over the specified area. Carefully press in place. Slowly peel back the remaining paper and
smooth the remaining portion in place. Small air pockets can be pierced with a pin and smoothed
out.

Assembly Instructions - 9620 Snowblower
1. Fasten the two quick hitch arms (#57) to the main body. Use eight 5/8" x 1 1/4" hex bolts, lock
washers and hex nuts. Note: Lift arms for quick coupling hitch are 30 3/4" long versus 35" for
the standard three point hitch.
2. Bolt the quick hitch (#56) to the snowblower body using two 1/2" x 1 1/4" hex bolts, lock
washers and hex nuts. Fasten to the lift arms using three 5/8" x 1 1/2" hex bolts on each lift
arm. Insert a 1" top link pin at the top and two 1 1/8" lift pins at the bottom of the hitch.
3. Bolt the hitch cross brace (#2) underneath the two quick hitch arms using two 5/8" x 1 1/2" hex
bolts, lock washers, flat washers and hex nuts.
4. Mount the discharge spout (#3) using the spout clamp (#51) bolted to the spout ring on the
snowblower. Lubricate the spout ring and clamp.
5. Hydraulic Spout Swivel:
a. Mount the swivel arm (#36) onto the swivel pin welded to the back corner of the fan housing
using a 1" ID flat washer (#37) and a 3/16" x 1 1/2" cotter pin (#52).
b. Wrap cable (#35) around spout and clamp to the ends of the swivel using 1/4" cable clamps
(#16).
c. With the spout turned forward and the swivel arm centered with the spout, clamp the cable
to the spout cable anchor using another cable clamp. Ensure that the spout is not jammed
and that there is no slack in the cable.
d. Use a standard 8" stroke cylinder (20 1/4" min., 28 1/4" max. pin centers).
e. NOTE: A hydraulic cylinder and hose kit to control the spout deflector is available as an
option.
6. Hand Crank (Option):
a. Fasten hand crank assembly (#50) using two 1/2" x 1 1/4" hex bolts, lock washer and hex
nuts.
b. Thread cable (#53) through hole in hand crank to even lengths and wrap around the tube to
each side of the hole four turns in opposite directions.
c. Turn spout to center forward position and clamp cable to cable anchor on far side of spout
using clamp (#16).

7. Mounting blower on tractor:
a. The pins supplied with the snowblower are for a category 2 quick hitch. The quick
coupling hitch has two holes both at the top of the hitch and at each lift arm. When using a
quick coupler, the pins must be in the inside set of holes. Use the outside set of holes with a
standard three-point hitch.
b. Using tape or a bright colored marking pen, mark on the outer shields the position where
the shaft is completely pushed together and the position where you have a 4"overlap. Watch
these marks when moving the blower through all possible operating angles to see that the PTO
shaft stays within this range.
c. With the engine on the tractor shut off, attach the PTO shaft. The tractor end has a standard
6-spline end with a spring loaded locking collar. The snowblower end has a clamp-style yoke
with a 3/8" key way. Slide the yoke onto the gearbox shaft with the 3/8" key supplied. Lock the
yoke in place with the 1/2" x 3" hex bolt and lock nut fitted through the groove in the gearbox
shaft. After tightening the bolt, insert and tighten the 3/8" socket set screw supplied.
CAUTION: Always check to see that both ends of the PTO shaft are securely attached every
time the Snowblower is used. This should always be done with the tractor engine off.
d. Check that the PTO shaft does not bottom or separate with the blower in the extreme high
and low positions. A longer optional PTO shaft is available if the standard shaft is too short.
Check for free movement of all parts in various raised positions; particularly the PTO shaft.
e. NOTE: Excessive U-joint wear and shear pin failure may result if the tractor PTO angle
exceeds 20. The drawing below gives an approximate way to check this angle. With the PTO
half extended, the tractor output should not be over 32 inches high. Use 34 inches if the PTO is
nearly fully extended and 30 inches if it is nearly compressed.

8. PTO Shield
All snowblowers are supplied with a PTO shield (#61). To install, remove the two rear bolts at
the top of the gearbox (#38). Bolt the PTO shield to the gearbox by the hinges using these same
bolts. A utility spring (#62) keeps the shield in place. Hook one end of the spring in the hole in
the shield and the other end to the hole in the brace under the gearbox.
CAUTION: Do not run the snowblower without this shield in place.
Refilling Gearbox with Oil:
If the gearbox requires refilling with oil because of repairs to the gearbox,
add oil to the level shown in drawing. Check the level regularly using the
plug in the lid. The correct level is even with the bottom of the plug.

13
Operation Instructions
1. Do not operate the blower in the fully raised position. The three-point hitch on some tractors
rises high enough to cause the PTO shaft to bind. This can cause damage to the PTO shaft and/
or to the hitch and pins.
2. Depth of cut can be partially controlled by tilting the blower forward or backward. Adjust the
tractor quick hitch so the snowblower is just slightly tilted back when resting on the ground.
CAUTION: Excessive backward tilt may cause the "U" joints to flutter resulting in PTO shear
bolt failure.
3. Run the blower at low rpm to check operation before blowing snow.
4. The snowblower has two shear bolts to protect the tractor and blower in case a large object
enters the blower. PTO shear bolt - two 5/16" x 1" (Grade 8); Auger shear bolt – 5/16" x 1 1/4"
(Grade 5). Shear bolts should be fastened with a lock nut or two jam nuts. These bolts must be
kept tight to prevent wear of the bolt and bolt holes.
5. Never run PTO shaft at over 600 rpm.
6. Chain Tension: Slack on the lower side of the chain should be 3/8" to 1/2".
7. Lubrication:
a. The spout clamps and rings should be periodically lubricated with gun grease.
b. PTO shaft universal joints and square shaft slide should be greased daily.
c. Regularly oiling the chain will significantly increase the life of the chain.
d. The grease fitting on the hydraulic spout swivel arm should be kept lubricated.
e. Gearbox - Use any 80-90 gear oil or multigrade with 80 minimum.
8. Periodically check all bolts for tightness. The bolt holding on the fan and the bearing bolts are
of particular importance.

9. DANGER: Always stop blowing for servicing or unplugging. The PTO should be
disengaged before dismounting from the tractor.
10. CAUTION: Always check to see that both ends of the PTO shaft are securely attached as
per instructions every time you are preparing to use the Snowblower.
11. Shear Sprocket: The shear sprocket (#24) should be checked at the beginning of every season
to make sure it will spin freely. With time this sprocket could corrode and seize which will not
allow the shear bolt to break if something jams in the snowblower auger. If necessary, clean
shear sprocket to ensure ability to spin freely.
12. When replacing bearings or tightening a loose bearing collar, always tighten collar in the
direction of shaft rotation using a center punch or a similar tool.
