Chapter ⅡBrief introduction on the structure and their adjustment
These catena rotary tillers are tillage equipment by means of the compound motion both of the rotation of the tractor going forward. It consists of universal
coupling, headstock, gearbox, side chain box (gearbox) are transmission sets. Blade and blade shaft are working parts. Headstock, the cover and trailing bar
are sets assistant. (Fig.1)

8
Fig.1 The side sketch of rotary tiller
2.1 Universal coupling assy
The universal coupling consists of universal joint head, universal joint head for male shaft, the universal joint head for female shaft and joint cross. There are
rings on the both ends of joint cross to avoid the movement of joint cross, and there is also a grease hole on the joint cross and the needle bearing can be
well lubricated if you inject grease into it frequently. The universal joint head for male shaft and the universal joint head for female shaft are sliding joint and it
can be pulled back and forth freely when the rotary tiller rises or falls. It must be noted that the interval between socket and shaft is in the shortest situation
but the socket and the shaft can not contact each other during operating, and if the interval between the socket and the shaft is in the biggest situation, the
overlap of socket and shaft must be longer or equal 1/2 length of the shaft.
2.2 Headstock
The upper hitch point on the headstock must be connected with the control link of the tractor and the lower coupling pin of headstock must be connected with
the tension link of the tractor to make the rotary tiller from the stable three-point hitch linkage.
2.3 Central gearbox assy
The central gearbox assy consists of gearbox, front cap, rear cap, first shaft, second shaft and a helical bevel gear pair that transmits the power to side chain
box, etc. And there is an oil hole for adding oil on the top of the gearbox. And there is a stopper for draining oil at the bottom of the gearbox. The helical bevel
gear is splined with the shaft. The gears are tightened with elastic collar, washer and locknut to prevent axial moving.
In using, the bearing clearance and the gear backlash will be changed because of wearing of bearings and gears, so you must adjust them (if necessary).
Adjustment of helical bevel gear backlash:
A proper backlash is the one of the condition for working normally. If the backlash is too small, result in the gear wearing rapidly or even biting one another. If
the backlash is to large, result in the gear making strong collision and loud noise.
Precaution:
Helical bevel gear backlash must be adjusted after the clearance of bearing on the first shaft has been adjusted. For retaining the clearance of bearing in
which have been adjusted, for pinion, the total thickness of adjusted shims of the front and the hind bearing seat on the first shaft must keep up. For example,
when moving the pinion forward, the decrease--the adjusted shims of the hind-bearing seat on the first shaft must added to the front bearing seat on the first
shaft, vice versa. For large helical bevel gear, when moving it rightward, you must decrease the shims of the bearing seat of the large bevel gear. In general,

9
just move the pinion forward when you do it.
Adjustment of the bearing axial clearance on the second shaft when the axial displacement was occurred very distinctly on the second shaft, you must adjust
it in time as following steps: First, loosen washer and screw down the locknut, then adjusts the displacement of the bearing on the second shaft until there
was no distinct axial movement and easy to rotate the shaft. Finally, lock the jam nut with the washer. This prevents the bearing from loosing.
2.4 Side gearbox assy
The side chain box consists of chain box, two chain wheels, chain, chain tension units, second shaft and shaft left side plate assy. Adjustment of the chain:
loosen and screw down the adjustable screw to adjust the tension of the chain, keep the right tension. In general, it can be pressed down 10mm at another
side of chain.
The side gearbox consists of side gearbox, three shaft and left side plate assy.
2.5 Right side plate assy
The right side plate assy consists of right side plate, right head of cultivator shaft, right side bearing and bearing seat.
2.6 Cover assy
A specific purpose of the cover is warding off clod, safeguarding the driver and still farther breaking the clod.
When rotary tiller is working, if the gap between the blade edge and the cover is too large, the cold would be thrown to the front of the cultivator shaft, so that
it will be cultivated once more, therefore the power of the tractor will be wasted; if the gap is too small, it is easy to congest. Recommend the normal gap is
30-45mm.
2.7 Cultivator shaft assy
The cultivator shaft assy consists of cultivator shaft, blade disc and blade.
2.8 Tailing bar
The function of the tailing bar is still farther breaking the clod and flatting the cultivator land. It was connected with cover. You can obtain different effect of land
surface by adjusting the height of the tailing bar. In general, if the soil is dry, to set lower, if the soil is wet, to set higher. When you remove the mud ande the
weed on the cultivator shaft, assemble the blades, long-distance transport; you can set the bar at the highest.

Chapter ⅢMethods of operating
3.1 Installation of headstock with the main body
Before being put in the container, the equipment is parted with the main body. The users refer to fig.2 simply to fix it on the main body with the bolts in the affix
pouch. Pay attention to fitting the spring washers on the bolts, and fastening them firmly.
3.2 The methods of blade mounting
To meet the requirement of agricultural technique, the blades are adopted different fixing methods, so that a variety of tillage effects can be gotten. Blades
should avoid mounting in reverse and making the back of the blades enter into soil. The parts will be damaged of overload.
The left-bent blades and the right-bent blades work in a stagger state on whole blade shaft. Only a blade enters into soil at the same time. This arrangement
is suitable to flat plowing. So the blade shaft operates stable; the surface of plowed field is smooth. To extend the application scope, every type of rotary tillers
has two sort of blade arrangement. Type 90 have 18 blades; type 100 and type 105 have 24 blades; type 125 and type 135 have 30 blades; type 150 have 36
blades; type 180 have 42 blades. Please take a strictly attention to mounting the blades according to the mark on the blade discs.
3.3 Connecting with the three-point linkage of tractor
The connecting way of rotary tiller with the tractor is three-point linkage. Its installing step is as follows:
1. Align the center of headstock by reversing the tractor, raise the link arm to appropriate height, reverse the tractor to make the link arm of tractor joint with
the left and right pin of rotary tiller.
2. First install the left lower linkage arm, then install right lower linkage arm, (because the leveling lift rod has screw that can be adjusted length.) finally inert
the pins.
3. Install the
upper linkage arm, and then insert the pin.
4. Mount the
universal coupling, and then insert the pins, poke the cotter pin.
It must be
taken attention to mounting order of the universal coupling.
Notes: it must
be given attention that the direction of universal coupling must be
correct in
installation if you use the universal coupling with female shaft.
(Fig.3, Fig.4)

3.4 Adjustment before working
1. Adjustment of horizontal level
Put it down to make the blade tips near to ground, observe that the height between the right and left blade tips and the ground is same or not. If not, it is
necessary that the right linkage arm of tractor be adjusted to level off the blade shaft, which ensures the uniformity of working depth.
2. Adjustment of longitudinal level
Fall the tiller to tillage depth desired, observe that universal coupling and PTO shaft are level or not. If the angle of universal coupling is too big, adjust the
control link to make it nearly level, which can maintain that universal coupling and the tiller work in the good condition.
3. Adjustment of rising height
Being forbidding that the tiller works at ±10°and above of the angle of universal coupling, turn at 30° and above, it is necessary to make the blade tips away
from the ground about 150mm-200mm. If require being risen higher when the tractor with the tiller passes through ruts and earth dyke or drive on the road,
the power driving the tiller must be cut off to prevent from danger. The position of the handle of the position control must be limited with the bolt if required.
4. Primary adjustment of working depth
Loosing the bolt on the lever limited the depth, adjust the position of the fixing hole, and then re-fix it, which the purpose is that the distance to the central
shaft be adjusted. Adjusted distance is 35mm per step.
3.5 Cultivating route
When working in a piece of large land, in land plowing is adopted to reduce the empty time in turn land, to raise work efficiency. The width of the plot selected
is whole number multiple of the working width or near as possible, so as to decrease repeat tilling. The width of the plot is commonly 15m or so, if too wide,

13
the empty time in turn land will be longer, the efficiency be less, the repeat times of idle motion be more, tne mud depth be longer.
The flat tillage in the medium and small fields refer to in land plowing.
Fig.5 In land plowing
3.6 Starting of the tiller
First, filling with gear oil in the gearbox and the side chain box, injecting grease to the crosshead and the bearing seat of the blade shaft. Then check for the
looseness of all connecting bolts and nuts, if loosing, screwing it at once. If the crack and deforming are founding in the blades, they must be replaced.
Starting tractor: rise the tiller and the blade tip must be away from ground 150mm-200mm, and joint universal coupling, then run in 1-2minutes, gear the
operating gear position and increase the fuel throttle opening, control the leveling handle to make the tiller enter into the soil gradually until the normal tillage

14
depth at the same time.
3.7 Selecting of forward speed
The selecting principle of tiller forward speed: the tractor cannot overload constantly; the performance of breaking soil meet the needs of agriculture
requirement, furrow bottom and the soil surface are smooth. Not only be tillage quality ensured, but also the rated power of tractor be made good use of, and
the purpose of rising work efficiency must be attained.
Generally, rotary tilling directly: 2 km/h, harrowing: 5 km/h-7 km/h; if the unit draft of the soil is digger, can select lower gear; contrarily select higher gear;
when working in dry fields, select low gear; when working in paddy fields, select higher gear.
3.8 Operating of headstock
1. Forbid to use the draft control of tractor during rotary tilling, so that protecting the tiller.
2. Using position control when the tiller works. The handle of draft control must be put in the position marks “up”.
3. When the handle of position control moves forward, the tiller fall down; contrarily the tiller rise.
4. After the tiller reaching to required depth, using the position hand-wheel to block it, in favor of that the tiller falls the same depth every time.
5. The detail refer to the instruction of matching tractor.
3.9 Loading the machine
1. This machine can be loaded by fork lift.
2. The fork of fork lift must be put into the bottom of this machine.
3. When loading the machine, please take attention the balance of this machine.

5. Check the tension of the side gears; adjust it if necessary.
4.2 Season maintenance (after one season operating)
Besides performing the proceeding of daily maintenance, the following must be done also:
1. Replace lubricating oil. It can be done in advance or delayed if necessary.
2. Check universal joint cross. If it is seriously worn, replace it.
3. Check the bearing in the twain ends of the blade shaft to see if turbid water enter it because of the faults of oil seals. Disassemble it to clean, replace the
oil seals and inject enough grease.
4. Check all bearings; adjust or replace them if necessary.
5. Check helical bevel gears; adjust them if necessary.
4.3 Yearly maintenance (after one year operating)
1. Remove all dust and filth away from the tiller.
2. Bleed out gear oil and disassemble the tiller to check on. If bearings be worn seriously or go wrong, it must be replaced; the parts must be cleaned before
assembled. Final, add new oil seals and inject enough grease.
3. Disassemble and clean the bearings and their seat of blade shaft, replace the oil seals and inject enough grease.
4. Disassemble and clean the universal joint cross assembly, and clean the roller pins of the universal joint, replace them if necessary.
5. Check the fastener and the cotter pins, etc. If the part is rusty or worn seriously, or the disable, it must be replaced.

16
6. Check the blades to see if there is crack, wear and tear on them, or loss. It must be replaced or added if necessary.
7. Check the blade holder, replace or repair them if necessary.
8. Repair the cover and the trailing bar.
9. The rotary tiller must be placed indoor as possible during it parks, and be raised to make the blade tips leave the ground. The blades and processing

Chapter ⅥNotes for safety
1. The operators must understand the operating characteristics and notes for safety.
2. Check the rotary tiller overall, it cannot be used until the technical condition is normal.
3. The angle of universal coupling is not more than ±10°when it is operating, and is not more than 30° when the tractor turns a corner in the field. You must
dismantle the universal coupling when long-distance transporting.
4. Do not engage the clutch behind the blades entering into the soil or fall down the rotary tiller sharply to prevent the transmission parts of the tractor and
rotary tiller form injured.
5. Do not plough when the tractor turns a corner in the field.
6. Do not plough when the tractor reverse.
7. Do not ride in tractor expect the driver when the rotary tiller is operating to prevent some one from dropping in rotary tiller.
8. Do not close the rotating parts when the machine is operating.
9. The machine must be stop and checked when hearing the abnormal noise in operating, and fix a breakdown.
10. The power from the PTO shaft must be cut off when checking the transmission parts, blades and gears etc. of rotary tiller. If the parts must be replaced, it
is necessary to stop the engine. Do not replace the parts when the engine is operating.
11. It is required that the driver should enhance his vigilance to cut off power to prevent from breakdown because the rotary tiller is a type of farm machine
driven by tractor.
