1. Confirm the position of the connecting chain case as Fig. 1.
[Fig. 1]
※Setting the “Thin”to see correctly, and the rotary shift lever to the forward 1st step.
2. Detaching for Tail Wheel
[Fig. 2]
5. Attaching the Implement

AF-300
10
Loosen the fixing nut and the bolt of the handle assembly, and detach the handle
assembly, and then, get the fixing lever loose, and detach the tail wheel assembly
downward therefrom.(Please keep the detached parts well in a safe place so that be
re-assembled later with no trouble.)
3. Assembling of Forming Rotors
1) Detach the implements assembled into the cultivating shaft before assembling
the forming rotors.
[Fig. 3]
2) As shown in Figure 3, assemble the two rotor shafts into sides(right and left) of
the cultivating shaft so that the bolt hole of each rotor(①) may be mated with the
groove of the cultivating shaft respectively, and tighten each locking bolt(②)
completely, and then fasten each nut(③) tightly so that the said bolts may not get
loose.t.

AF-300

3) The right and left side of this cultivator shall be the right and left side when
seeding the cultivator from its engine. So, after confirming the "Right" and "left"
as inscribed on each hexagonal part of the rotor assembly ⑥(RIGHT, SMALL)
and ④(LEFT, SMALL), assemble them into the right and left rotor ①
respectively so that the blade of each rotor assembly nay be symmetric mutually.
4) Then, after confirming the "Right" and "Left" as inscribed on each hexagonal part
of the rotor assembly ⑦(RIGHT, LARGE) and ⑤(LEFT, LARGE), assemble
them into the right and left rotor shafts ①with each one set in the same
direction as each hexagonal fixing bolt of the rotor assembly ⑥and ④so that
the blade of each rotor assembly may be symmetric mutually.
5) If the rotor assemblies are assembled into the rotor shaft with them set reversely
in the right and left side, or each direction of the right and left rotor assemblies is
not symmetric mutually and consequently the blades of the large and small rotor
assemblies are wrongly, it causes the work to be done poorly and further the
engine to have an overload. So, please be much cautious not to assemble them
so wrongly.
4. Assembling of Forming Plates
[Fig. 4]

1) Get the hexagonal part of the T-supporter in tight contact with the hexagonal hole
of the rotary frame with the tail wheel assembly detached therefrom as shown in
Fig. 2 by pushing the said hexagonal part upward from underside, and tighten
one fixing lever slightly.
2) Before tightening the fixing lever, confirm whether the intervals between the right
and left rotor blades and the forming plates are similar by rotating the rotor
assemblies manually, and tighten the fixing lever completely.
5. Assembling Pneumatic Tires with the Right Tire Exchange with the Left One.
1) Since the work of forming the ridge is being done while the ridge former is being
moved backward, assemble the pneumatic tires with the right tire exchanged
with the left one.
2) If the steel wheels for tracking are assembled into the shaft in the inner side of the
pneumatic tires respectively and in the slippery soil, the work can be done more
efficiency.

1. Work for Forming the Round Ridge
[Fig. 5]
1) Before doing the forming work, decide how wide the ridge is to be formed, and
then, for adjusting the width of the ridge, loosen the right and left bolts for fixing the
forming plates and get the 4 wing nuts for fixing the width-adjustable plate loose
slightly and further set the forming plates at the desired width. And then, fasten the
bolt and wing nuts completely, and as confirming the notches on the hexagonal
pipe, set the right and left forming plate assemblies so that the width of right plate
assembly from the T-shape supporter tie bar may be the same as that of the left
one. Then, fasten the right and left bolts for fixing the forming plates completely.
2) In case that the ridge is to be made more than 600mm wide, set the respective last
blade ends of the rotor assembly ⑦(RIGHT, LARGE) and ⑤(LEFT, LARGE) as
referred to in Fig. 3 so that they may be protruded from the respective ends of the
right and left forming plate assemblies by 5～10mm, and then fasten the right and
left bolts for fixing the forming plates completely. Then, as keeping the rotor
assembly ⑥(RIGHT, SMALL) and ④(LEFT, SMALL) at an adequate interval
respectively in the inner side of the rotor assembly ⑦(RIGHT, LARGE) and ⑤
(LEFT, LARGE), fasten the right and left bolts for fixing the forming plates
completely.

3) In case that ridge is to be made 400～500mm wide, detach the rotor assembly
⑥(RIGHT, SMALL) and ④(LEFT, SMALL) as referred to in Fig. 3, assemble only
the rotor assembly ⑦(RIGHT, LARGE) and ⑤(LEFT, LARGE) into the shaft, and
set the respective blade ends of the rotor assembly ⑦(RIGHT, LARGE) and ⑤
(LEFT, LARGE) so that they may be protruded from the respective ends of the
right and left forming plate assemblies by 5～10mm, and then fasten the right
and left bolts for fixing the forming plates completely.
4) Proper position of the height-adjustable wheel is variable according to the soil
condition, the cultivating depth by the rotary cultivator, the water portion, etc. in
the field, and therefore, as doing the work little by little, loosen the right and left
height- adjustable bolts and then, adjust and fix the height-adjustable wheel at a
proper position. Then, use the former.
2. Work for Forming the Square Ridge
[Fig. 6]
1) Decide how wide the square ridge is to be made and further which one is to be
selected as the height of it, 150mm or 180mm, and loosen the 4 wing nuts (M8)
for fixing the width-adjustable plate with the round ridge having been formed, and
then, detach the width-adjustable plate. Then, assemble the forming plate for the
square ridge in place of the width-adjustable plate. Please keep the detached
plate well in a safe place.

AF-300

2) When the right and left forming plates for the square ridge are assembled into
the lower holes respectively on the right and left forming plates, the ridge
becomes 150mm high. And, when they are assembled into the upper holes
respectively on the right and left forming plates, the ridge becomes 180mm high.
3) When the right and left bolts fixing the right and left forming plates are loosened
and the right and left forming plates are pushed inwardly to the end and
assembled, the ridge becomes 350mm wide. And, When they are pulled
outwardly to the end and assembled, the ridge becomes 700mm wide. So, set
the right and left forming plates at a proper width as desired, and fix them by
fixing M8 bolts and the wing nuts completely.
4) As confirming the notches on the hexagonal pipe, set the right and left forming
plate assemblies so that the width of the right plate assembly from the T-shape
supporter may be the same as that of the left one. Then, fasten the right and left
bolts for fixing the forming plates completely.
5) In case that the ridge is to be made less than 500mm wide, detach the right and
left rotor assemblies(SMALL) in the inner side, like the case that the round ridge
is to be made 400～500mm wide. And then, assemble only the right and left rotor
assemblies(LARGE) in the outer side into the shaft, and set the respective last
blade ends of the right and left rotor assemblies (LARGE) so that they may be
protruded from the respective ends of the right and left forming plate assemblies
by 5～10mm, and then assemble them by tightening the right and left bolts for
fixing the forming plates completely. And then, use the forms.
6) In case that the ridge is to be made 600～700mm wide, assemble the right and
left rotor assemblies(LARGE, SMALL), like the case that the round ridge is to
made more than 600mm wide. And then, use the forms.
7) For adjusting the hardening condition and the height of the ridge, fix the height-
adjustable wheel at a proper position by adjusting the height-adjustable wheel
upward or downward. And then, use the former.

3. Applied Works of the Ridge Former
■Working with only the Forming Rotors being attached.
1) When the forming are detached the former and the tail wheels are assembled
into the rotary frame to the original condition and further the forming rotors only
are assembled there into, the covering work can be done.
2) In the above condition, when the right and left forming rotors are assembled
reversely (the right rotor in the left side, and the left one in the right side), the
levelling work can be done.
3) Get the pneumatic tires back to the original condition, and shift the driving gear to
the forward position.
■Working with only the Forming Plates being attached.
1) When the right and left forming plates are assembled reversely (the right plate in
the left side, and the left one in the right side) as shown in Fig. 7 and the forming
rotors and shafts are detached from the cultivating shaft and the blades for
ditching are assembled into the cultivating shaft, the earthing-up work and the
ridging work can be done by driving the plow backward. (Only Steel Wheels for
Ditching to be used)
[Fig. 7]

2) When the of the ridge is adjusted by the height-adjustable wheel during the
forming work of ①, the square ridge can be formed 15～20cm wide so that
vegetables, potatoes, garlics, etc. can be planted.
[Fig. 8]
1. Checking Points before Working
1) Check once more whether the ridge former is assembled into the cultivator or not,
and whether the bolts and the nuts are tightened completely or not.
2) Check whether the blade ends of the rotor assembles are protruded from the
right and left ends of the forming plate assembles by 5～10mm.
3) Check whether the forming plates are of the right shape as desired or not, and
whether the width-adjustable plate is assembled at the desired width or not.
4) Check whether the cultivating condition of the field, where the work is to be done,
is deep so sufficiently, or not. If the condition thereof is poor, do the rotary work
once more by the tractor or the power tiller and check whether the humidity of
soil is adequate or not. If the depth and humidity of the cultivating is not adequate,
it will cause the ridge not to be formed well.
7. Checking Before Operation and About Safe Operation

2. How to Operate
1) Get the engine started while the main clutch of the main body of the cultivator is
in the disconnection position, and lower the rotative speed to the low speed.
2) Get the driving shift lever in the neutral position, and then, as standing by the
side of the cultivator and getting the main clutch to be in the connection by one
hand, shift the gear to the first step of the forward rotation.(See the Working
Information Label)
3) After confirming whether there is any obstacle in the rear side, get the driving
shift lever in the backward direction and the first step speed position. And then,
the operator keeps his balance, and he gets the main clutch to be in the
connection position slowly. In the meanwhile, the former gets to be driven
backward so that the work gets to be done.
【CAUTION 】
●Please be sure to connect the main clutch of AMC-800 cultivator with the low
speed. If it is connected with the high speed, the speed gets to be too fast, and it
is very dangerous.
●Be cautious so that no rotor blade may get in contact with the operator's foot
when shifting the cultivating shift lever to the operation position.
4) When the engine has much load, push the handle slightly. When the ridge is
hardened poorly or the soil amount is short, bring strength to the handle so that
the backward driving speed may get to be slow.
5) When turning the former, if the operator gets the driving gear to be at the forward
direction and the first step speed position and he is pushing the handle and
simultaneously turning it, he can turn it with much ease.
