74” Allied Snowblower
This manual is for 74" snowblowers with an open gear gearbox. When ordering parts,
specify model number and serial number. The snowblower is the push type and will
mount to a tractor with a 540 rpm PTO. It is supplied with category 1 pins and also
bushings, which convert the pins to a category 2. A category 1 Quick Hitch also fits on
this snowblower. This 74" wide snowblower comes with a hydraulic chute control as
standard equipment. A hand crank chute control is 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 let anyone stand behind the tractor in the area of the discharged
snow.

OPERATING INSTRUCTIONS
1. Do not operate the blower in the fully raised position. The three-point
hitch on some tractors raises high enough to cause the PTO shaft to bind.
This can cause damage to the PTO shaft and/or to the hitch and pins.
ALERT: PTO shaft angle should not exceed 20 degrees for
optimum performance and life. Damage may occur to PTO and/or
snowblower if angle becomes more extreme.
2. Depth of cut can be partially controlled by tilting the blower forward or
backward. Adjust the top link of the tractor 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. Adjust the lower link sway chains or blocks on the tractor to restrict side
movement of the blower when operating.
4. Run the blower at low rpm to check operation before blowing snow.
5. 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 5) Auger shear bolt (1/4" x 1"-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.
6. Never run PTO shaft at over 600 rpm.
7. Chain tension: Slack on the lower side of the chain should be 3/8 to ½”.
8. 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.
9. Periodically check all bolts for tightness. The bolt holding on the
fan and the bearing bolts are of particular importance.
10. DANGER: Always stop blower for servicing or unplugging. The
PTO should be disengaged before dismounting from the tractor.
11. 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.
12. Shear Sprocket: The Shear Sprocket (#52) 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. Clean to loosen if
necessary.
13. 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.

ASSEMBLY INSTRUCTIONS
1. Turn the bottom tube weldments (#9) as shown in drawing and slide them into
the sleeve welded to the main body. These tubes have holes for two positions.
The correct position for each individual tractor will be determined when mounting
the snowblower on the tractor. These tubes are connected to the tractor with a
¾” x 4 ¼” pin (#96) and a hairpin clip (#104).
2. Bolt the left (#20) and the right (#21) a-frames to the inside of the plates welded
to the hitch tubes using 7/8” x 2 ½” hex bolts (#102) and lock nuts. Join the top
of the hitch arms by bolting a 1” O.D. x 2” spacer (#100) between the top plates
using a ¾” x 4” bolt, lock washer and hex nut through the lower outside holes.
Bolt the upper hitch tube weldment (#47) between the same plates using the
same size of bolt. Use the inside holes on the top plates for the upper tube. The
other end of the top hitch tube bolts between the welded brackets on the top
edge of the fan housing with the same hardware. Tube must be turned as shown
in drawing. Tighten all hardware.
3. A category 1 top link pin (#18) is fitted in the top holes of the hitch arm plates.
This pin is used for standard three-point hitch only. The bushing in the lower
holes is used for the quick hitch.
4. Mount the discharge spout (#6) using the spout clamps (#59) bolted to the spout
ring on the snowblower. Lubricate the spout ring and clamps.
5. Hydraulic spout swivel:
a) Mount the arm swivel (#60) onto the swivel pin welded to the back corner
of the fan housing using a 1" I.D. washer (#29) and a 3/16" x 1 ½” cotter
pin (#62).
b) Wrap cable (#61) around spout and clamp to the ends of the swivel using
3/16" cable clamps (#17).
c) With the swivel in extended position (i.e. cylinder fully extended) and the
spout turned to the right, clamp the cable to the spout cable anchor using
a ¼” cable clamp (#84).
Ensure that the spout is not jammed and that there is no slack in the
cable.
d) Use a standard 8" stroke cylinder (20 ¼” min., 28 ¼” 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 crank assembly (#5) using two ½” x 1 ¼” hex bolts, lock washers
and hex nuts.
b) Thread cable (#7) 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 (#84).

ASSEMBLY INSTRUCTIONS – cont’d.
7. Mounting blower on tractor:
a) Mount the blower on a tractor with a category 1 or category 2 hitch.
b) Using tape or 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" keyway. Slide the
yoke onto the gearbox shaft with the 3/8" key supplied. Lock the yoke in
place with the ½” 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.
8. PTO Shield: All snowblowers are supplied with a PTO shield. Bolt the shield (#74)
to the hinges on the top of the gearbox on the snowblower using ¼” x ½” hex bolts,
lock washers and hex nuts. Insert a 3/16" cotter pin in the hole in the shield and
in the hole at the bottom corner of the gearbox. Fold back the cotter pins to hold
them in place. Hook the ends of the spring (#71) into these cotter pins to hold
the shield down. Bolt the PTO shield to the gearbox plate using these same
bolts. Insert a 3/16" cotter pin in the hole in the shield and fold to lock in place.
Hook one end of the spring (#71) into this cotter pin and the other end into a hole
in the lower gearbox plate to hold the shield in place.
CAUTION: Do not run the snowblower without this shield in place.
