INTRODUCTION

Buhler Farm King has years of snowblower manufacturing expertise and thousands of
acreages, farms and cities depend on Buhler snowblowers.

PTO-driven Buhler Farm King Snowblowers attach to 3-point hitch.
This snowblower is supplied with category 2 pins with conversion bushings to category
3 available. 740 and 840 Snowblowers have open gearboxes. The Y840G has an oil
bath gearbox. Adjustable cup type skid shoes are standard on all models.
Three blade fans are on all models. A 4 blade fan is also available as an option.
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. A longer 36"
PTO shaft is optional on the Y740 and Y840 models.

Also available is an optional Hydraulic Spout Control. 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 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 Buhler Dealer if you need assistance, information, or additional copies of the
manual. Visit our website at www.buhler.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.

1. #740: Turn the bottom tube weldments (#9) as shown in drawing and
slide them into the sleeve welded to the main body.

#840 & #840G: Turn the bottom tubes (#93) as shown in drawing and slide
them into the sleeve welded to the main body.

ALL SIZES: The correct position for each individual tractor will be determined
when mounting the snowblower on the tractor. These tubes are connected to the
sleeves with a ¾” x 4 ¼” pin (#96) and a hair pin clip (#103).

2. #740: 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 (#101) and
lock nuts. Join the top of the hitch arms by bolting a 1” o.d. x 2” spacer
(#19) 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.

#840 & #840G: Turn the hitch weldment (#4) as shown in drawing. Bolt
the hitch to the two bottom tubes (#93) using 7/8” x 5” bolts (#102) and
lock nuts. The upper hitch tube (#80) bolts to the top of the hitch and the
welded brackets on the top edge of the fan housing using ¾” x 4” bolts
(#97), lock washers and hex nuts. Tube must be turned as shown in
drawing. Tighten all hardware.

3. #740: 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.

#840 & #840G: The hitch fits standard category 1 and 2 three-point
hitches as well as category 1 and 2 quick hitches. The highest and lowest
holes are for standard three-point only. The inside set of holes must be
used for a quick hitch. Adaptor bushings are supplied to convert from
category 1 or 2.

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.

740, 840 & 840G Snowblowers

ASSEMBLY INSTRUCTIONS – cont’d.

5. Hydraulic spout swivel:
a) Mount the swivel arm (#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 hand 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).

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 .

ASSEMBLY INSTRUCTIONS – cont’d.

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 both the #740 and
#840 snowblowers 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. To
mount the shield (#74) on the #840G snowblower, remove the two rear bolts at
the top of the gearbox (#63). 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.

740, 840 & 840G Snowblowers

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.
NOTE: 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 1/2 inch.

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.
e) For #740 & #840 only: Gearbox is open type and need not be greased
or lubricated.
For #840G only: See Section on refilling for correct oil level.
Use any 80-90 gear oil or multigrade with 80 minimum.

10

740, 840 & 840G Snowblowers

OPERATING INSTRUCTIONS – cont’d.

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.
