Introduction
Farm King has years of snowblower manufacturing expertise and thousands of acreages, farms
and cities depend on Farm King snowblowers. PTO-driven Farm King Snowblowers attach to a
3-point hitch. A hitch system, which is quick-hitch compatible, is standard on all models.This model
is supplied with Category 2 pins, as well as conversion bushings to Category 3.
A 7' or 10' commercial truck loader chute is available as an option. Adjustable cup type skid shoes
are standard on all models.This model has a 4 blade fan and Hydraulic Spout Control as standard
equipment.
There is a shear bolt on the drive shaft 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 Farm King
Dealer if you need assistance, information, or additional copies of the manual. Visit our website
at www.buhlerindustries.com for a complete list of dealers in your area.
The directions left, right, front and rear, as mentioned throughout this manual, are as seen facing
in the direction of travel of the implement.

Assembly - 1080 Snowblower
Assembly Instructions
1. Hitch Assembly: With lower hitch tubes (#3) turned as shown in drawing, slide them into the
sleeves welded to the main body.These tubes are adjustable to two different positions.The
correct position for each individual tractor will be determined when mounting the snowblower
on the tractor (see Section 4). Start with the tubes pulled out to the last hole.These tubes are
connected to the snowblower with a 1-1/4" x 5-1/2" pin (#6) and a hairpin clip (#12). Slide the
3-point hitch (#2) into the top sleeve on the snowblower body and hold in place with a 1" x
4-3/8" pin (#7) and a hairpin clip (#12). Bolt the bottom of the hitch to the ends of the hitch
tubes using 1/2" x 2" hex bolts, lock washers, flat washers and hex nuts.
2. Spout Assembly: Mount the discharge spout (#64 or #73) using the spout clamp (#22) bolted
to the spout ring on the snowblower. Lubricate the spout ring and clamp. Mount the 5" stroke
cylinder (#68) on the spout as shown in the drawing.
CAUTION
The ports in the cylinder are both 9/16" ORB. Be sure that the
bottom edge of the deflectors are properly fitted in the guides
before using the hydraulic control.
3. Hydraulic Spout Swivel:
- Bolt the cylinder arm base (#17) to the bottom of the hitch using 5/8" x 2" hex bolts, lock
washers and hex nuts. NOTE:There are three sets of holes.The hole used to bolt on this
base must match with the holes used to assemble the hitch in the hitch tubes (i.e. 1st hole,
second hole, etc.)
- Mount the spout swivel (#16) onto the swivel pin welded to the back corner of the fan
housing using a 1-1/4" I.D. flat washer (#31) and a 1/4" x 2" cotter pin (#32).
- Wrap cable (#18) around spout and clamp to the ends of the swivel using 3/8" cable clamps
(#19).
- 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.
- Use a standard 8" stroke cylinder (20-1/4" min., 28-/2" max. pin centers).
4. Mounting Snowblower onTractor:
- Mount the snowblower on a tractor with a Category 2 or 3 standard hitch or a Category 3
quick hitch.The hitch has two holes both at the top of the hitch and at each lift arm. When
using a quick hitch, the pins must be in the inside set of holes. Use the outside set of holes
with a standard three- point hitch.The lift arm pins also have a narrow spacing for Category
2 and a wide spacing for Category 3.
- Using tape or a bright colored marking pen, mark on the outer shields of the PTO the
position where the shaft is completely pushed together and the position where you have
a 4" overlap. Watch these marks when moving the snowblower through all possible
operating angles to see that the PTO shaft stays within this range. Slide the hitch in if
necessary to keep the PTO shaft in this operating range. Do not forget to change the
position of the cylinder arm (#17) by the same distance that you move the hitch.

10
Assembly - 1080 Snowblower
- With the tractor engine shut off, attach the PTO shaft.The tractor end has a 1-3/8" 21 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 1-3/4" jackshaft with the 3/8" key supplied.
Lock the yoke in place with the 5/8" x 3-1/4" 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.
- 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.

11
Operation - 1080 Snowblower
Operation Instructions
1. Do not operate the snowblower in the fully raised position.The 3-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.
2. Depth of cut can be partially controlled by tilting the snowblower 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
snowblower when operating.
4. The snowblowers may be purchased with either of two available spouts. Both spouts have
hydraulically controlled spout deflectors.The standard spout should be suitable for all general
snow blowing applications.The truckloader spout was designed to blow directly onto the back
of a truck.The maximum height of the truck side you blow over should be approximately 10 ft.
5. Run the snowblower at low RPM to check operation before blowing snow.
6. The snowblower has shear bolts to protect the tractor and snowblower in case a large object
enters the snowblower.The PTO shaft uses two - 3/8" x 1" (Grade 2) hex bolts as shear bolts.
The drive shaft uses one - 5/16" x 1-1/4" (Grade 5) hex bolt as a shear bolt. Shear bolts should
be fastened with a lock nut.These bolts must be kept tight to prevent wear of the bolt and bolt
holes.
7. Never run PTO shaft over 1000 rpm.
8. ChainTension: Slack on the lower side of the chain should be 3/8" to 1/2".
9. Lubrication:
- The spout clamps and rings should be periodically lubricated with gun grease.This is
particularly important on the truckloader spout which turns harder than the standard spout
due to length and weight.
- PTO shaft universal joints and square shaft slide should be greased daily.
- Regularly oiling the chain will significantly increase the life of the chain.
- The grease fitting on the hydraulic spout swivel arm should be kept lubricated.
- Use only 80-90 gear oil on multi grade with 80 minimum in the gearbox up to the level
plug height.

12
10. Periodically check all bolts for tightness.The bolt holding on the fan and the bearing bolts
are of particular importance.
DANGER Always stop snowblower for servicing or unplugging.The PTO
should be disengaged before dismounting from the tractor.
11. Shear Sprocket:The shear sprocket (#52) should be checked at the beginning of every season
to make sure it will spin freely. Clean to loosen if necessary.
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.
CAUTION
Avoid raising or lowering snowblower under load. Doing so can
create excessive end pressure on the PTO shaft which could lead
to bearing failure on the snowblower.
