Running principle

Combine main features Twin Master Peanut Combine are:
Peanut pickup is carried out by a cylinder with pickup fingers of plates that throw the product up to the auger, from where it is put on the way to the conditioning cylinder that, at last, directs it to the threshing cylinder.
Sliding shoes allow the pickup unit to follow up the terrain unevenness, making the pickup fingers to work very close to the soil surface, picking up the plants that should be arranged in furrows form. Threshing occurs through the Axial Flow of Low Impact system (FABI). Beating pins, arranged along the whole helicoidal cylinder length, make the threshing and keep the screen around it from being obstructed by the straw, besides adjusting threshing time. Peanut passes by the screen around the threshing cylinder and falls on the vibrating sieve, occurring the separation of the “peanut + thin straw” from the thick straw which is eliminated by the cylinder. Cleaning fan sucks the light particles of dirt (thin straw), allowing only the peanut to be led to the Combine rear part. In the rear part, below the sieve, there is a deposit from where the product is transported to the elevator through a auger That elevator transports the peanut up to the grain box. Product unloading occurs through the box tilting by means of hydraulic cylinders.

 Work conditions

Combine most output Twin Master Peanut Combine in your crop depends on several factors among which the main ones are: terrain general characteristics, peanut characteristics, moisture and Combine moving speed.
Carefully fulfil all topics below.

Soil characteristics

Surface evenness
The more even is the soil surface, the less will be the pod loss and the better will be machine runs during pickup. Every crop, during soil preparation, tries to make surface even getting rid of unevenness.

Moisture conditions

Do not wait for all the product in furrows to get to an ideal and even moisture level to gather it. Start picking up with the moisture level a little higher than the ideal one because the product dries along the process. Avoid getting to the end of the work with the material much dry because it can cause break and loss of pods. By the way, moisture conditions change throughout the day. Early in the morning, there is the dew influence which increases the moisture of the product and delays the beginning of the threshing.
According to the region, pickup starts only after 10:00, 11:00 or even 12:00 o’clock.

C – Side tilt

Soils that present side tilt greater than 10 % (see figure on the side) can cause the Combine to overturn. Therefore, avoid working in such situations.

Warning:
Be careful with holes and swells on the soil.

Recommendations for a good mechanical   harvest
A good mechanical harvest begins with correct soil preparation. Below there are some important procedures that aim to increase the crop output:

• Try to level the soil up to the best possible, getting rid of natural soil waviness.
• Continuously remove stubs, stones and any other type of obstacle there is in the area.
• In the case of direct planting, handle the straw in a such way as to make the surface even and prevent high rootstock from appearing because it will mix with the furrows. For instance: corn stalks that remain after harvest. Be careful with the ruts left by the pivot
• wheels. When crossing them, reduce the tractor’s speed to pre-vent a more violent impact.
• Avoid gaps along the furrows because they make the threshing cylinder to work idle for short periods of time and it can cause break and/or loss of grains.

Considerations about work capacity

Twin Master Combine work capacity depends on the soil conditions, crop characte-ristics and operator’s skill with this type of equipment. Operator should work at the highest speed possible, according to moisture con-ditions, safety and product characteristics, aiming to not harm machine running neither cause losses in the field. It is better to work at a lower speed, harvesting a smaller area per day than speed up and increase loss level to above acceptable. Machine work can also be harmed, causing unnecessary maintenance service.

Machine preparation

Leveling and coupling to the tractor

• On a firm and flat place, turn the crank (1) of the stand jack (2) in a such way that the Combine be leveled (parallel) in relation to the soil.
• Put the tractor near the Gatherer. Draw-bar should coincide with the coupling terminal of the header (3). In case there is need, adjust the draw-bar according to your tractor Instruction Manual.
• Couple the tractor draw-bar with the coupling system of the Combine and put the lock.
• Release the stand jack using the crank, release the pin and put it in transporting position (4).

Hydraulic coupling
In the tractor remote control, use the three hydraulic lines, connecting the hoses like this:

Line nº 1 – for driving:

• Tilt (raise and lower) of the pickup unit (6).

Line nº 2 – for driving:

• Tilt (raise and lower) of the grain box (7).

Line nº 3 (optional) for driving:

• Hydraulic motor for driving the pickup cylinder of the pickup unit.
• Hydraulic motor to drive the spreading auger that spreads the peanut pods (grain tank).
• Remove the protecting plugs (5) from the three pairs of hoses of the machine and from the tractor remote control terminals.
• Connect the hoses firmly pushing their terminals against the remote control terminals (according to figure 1).

Removing the hydraulic hoses

• Move the respective remote control levers to lower the grain tank (7) and the pickup unit (6), in case they are raised.
• Turn the tractor machine off.
• Move the remote control levers in both directions to relieve the residual pressure in the circuit.
• Remove the hoses and put all the protecting plugs (5) back.

Warning:

1. If pressure remains in the hoses, relieve such pressure before connecting them again. It can be done compressing the check valve of the ends of the hoses against the bottom of a clean recipient (bucket or can), protecting yourself from the resulting oil jet.
2. Never remove the hoses of the tractor remote control with the system pressu- rized.
3. Oil jets under pressure can penetrate skin causing serious injuries. Because of that, it is important to relive the pressure before performing any maintenance in hydraulic systems. If even with all caution there is penetration of hydraulic fluid in your skin, seek for a doctor.

Grain elevator assembly

Elevator (8) is not disassembled for Combine transport, but it is folded according to side figure. Put the elevator in work position according to the following:

• Tie the ends of the chain (9) with wire or rope, preven-ting the mugs (10) from displacing inside the elevator.
• Fully unfold the elevator (8).
• Install the screws + nuts (11) to fasten the upper part of the elevator (8), according to the figures below.
• Remove the bottom inspection cover (12).
• Remove the wire or rope and splice the chain (9).

NOTE:
See in page 32 some information about the cor-rect chain splicing

• Adjust the chains play (9) using the side stretchers  (13), according to instructions in page 34.v

NOTE:
Upper bearings (14) should be aligned.

Pickup unit assembly

In case the pickup unit (15) comes disassembled from the machine, assemble it according to instructions as follows.

Note:
Perform this procedure on a flat and firm ground.

• Couple the Combine to the tractor according to instruc-tions in page 15 and scotch the wheels with wooden wedges.
• Safely hang the pickup unit (15) (with a tractor equi-pped with “boom” and a cork belt, for instance) and position it under the header (16), in a such way that it stays aligned in relation to the Gatherer.
• Fasten the pickup unit (15) to the Combine side stand points (17), using four screws (18) + washers + nuts on each side.
• Fasten the terminal with the oblong seat of the raise cylinder (19) to the pickup unit stand point (15), using the pin + washer + screw kit (20).

Cardan length adjustment
About the adjustment, refer to the cardan shaft manual instructions.

Adjustments to start the operation

Power take off rotation

During the operation, the power take off rotation should be kept constant at 850 rpm.

Tractor work speed

Correct tractor moving speed is one of the factors that directly influences the gathered product final quality. Recommended speed is around 3,0 to 8,0 km/h.

Pickup unit

• A – Point of support identification 1 – Sliding shoes: support the pickup unit, making it toslide on the soil.
• B – Adjustment of the pickup fingers height in relation to the soil To get full pickup of the peanut furrows, the recommended distance from the end of the pickup fingers (2) in relation to the soil be between 25 to 50 mm.
  Such height adjustment should be done through the lever corresponding to the line nº 1 of the tractor remote control (see page 16): fully hang the pickup unit and then slowly lower it up to reach the spacing measure described above. Such measure check can be done visually or using a mea-suring tape, in case there is need. Reaching the proper measure, keep the remote control lever in that position during the work.

Beating cylinder (FABI)

High performance cylinder of Axial Flow of Low Impact. The only item that requires adjustment in the threshing cylinders (3) are the beating pins (4).
A – Beating pins position

Warning:
Never work under the grain tank before fitting the safety lock (5) on the hydraulic cylinders rod (6).
NOTE:
Beating cylinders turn in reverse direction. The right cylinder turns counterclockwise (in relation to whom is sitting in the tractor seat) and the left one turns clockwise. Therefore, the beating fingers also stay in reverse position comparing to both cylinders.

The pins (4) have three work positions, defined from the product conditions. Those positions are:
Position A: P ins at (+45º) in relation to the auger in the material movement direction. Provide a shorter threshing time because the material passes quicker through the system. Indicated to less productive peanut crops, with less amount of mass and dryer.
Position B : Pins (4) at (0º) in relation to the auger (3). Provide an ideal threshing speed to the peanuts that are within the ideal moisture range.
Positiom C: Pins at (-45º) in relation to the auger in the material movement direction. Provide a longer threshing time (because the material passes slower through the system), preventing grain loss along with the straw that is thrown away at the end of the process. Indicated to much productive peanut crops, with great amount of mass and moisture above ideal level.

Beating pins adjustment

Note:
Pins (4) adjustment should begin by the front part of the beating cylinder (3), with the tractor engine turned off and cylinder safety lock in place.
Warning:
Never work under the grain tank before fit-ting the safety lock on the hydraulic cylinders rod, according to figure in the previous page.

• Release the pins (4), loosening the nuts (7).
• Adjust the pins (4) in the desired position (inclination)(A, B or C – see previous page).
• Adjust the distance between the pins (4) and the screen (8) according to topic “C” below.
• Re-tighten the nuts (7).

Distance between the beating pins and cleaning screen
When the distance from the pins (4) in relation to the screen (8) is short, there will be a more severe threshing. As the distance is increased, threshing gets softer, but a straw coat can build up along the screen, making difficult the pods pass. Position the pins at 2 cm and change it, in case there is need, after beginning field work.
Procedure:

• Release the pins (4), loosening the nuts (7).
• Change the distance between the pins (4) and screen (8) according to needs.
• IMPORTANT: Re-tighten all nuts (3).

Note:
If the distance from the pins (4) in relation to the screen (8) is much long, a straw coat can build up around the cylinder (3), making difficult the pods pass.

Cleaning system

Bottom plate (9) and upper windows (10), mounted in the Combine rear part, are in charge of the adjustment of the air flow for product cleaning.   Adjust the plate (9) position along with windows (10) posi-tion  in a such way to have a satisfactory cleaning with the least air flow possible.  The more close the plate (9) and windows (10) are, the hi-gher the suction power and, therefore, better is the cleaning. The more opened the plate (9) and windows (10) are, lthe lower the suction power and, therefore, lower is the clea-ning power. Release the nuts (9a) and both wing nuts (10a), adjust according to need and after that re-tighten the nuts.

Note:
Excessive air flow can cause grain loss by the fan, being thrown by the straw outlet (11).

Operating the combine

Notes:

• Operator should suit these procedures to his needs.
• Be aware of all safety instructions before operating the Combine for the first time.

1. Before starting the Gatherer, make sure preparation, adjustments and lubrication  are correctly done.

2. Start the tractor and drive the power take off, putting it in the suitable rotation (850 rpm).

3. Align the Combine in front of the first furrow.
   Note: Avoid gaps in the furrows because the beating cylinder should not work without product

4. Put the lever corresponding to line nº 3 of the remote control in “floating” position (see page 16).

5.  Adjust the pickup fingers height in relation to the soil using the lever of the line nº 1 of the remote control, according to instructions in page 16.

6.   Perform the pickup moving the tractor in suitable speed, according to guidance in page 20.
   Note: Threshing system efficiency largely depends on the evenness of the machine feeding.

7.  When carrying out maneuvers, always raise the pickup unit (see instructions in page 16), turn off the power take off and hold on around 30 seconds till all material held inside the Combine be processed.
   Note: If the driving cardan is “homokinetic” type, there is no need for turning off the power take off.

8. After full grain tank loading, move tractor out of the furrow and hold on around 30 seconds till all material held inside the Combine be processed.

9. held inside the Combine be processed. Move the lever corresponding to the line nº2 of the remote control backward till you completely raise the grain tank.
   After all grains have been thrown out, move the lever frontward till you completely lower the grain tank.
   Note: The most distance between the wagon and grain tank should be of 500 mm.

10. 10 – Avoid excessively transit with the Combine, outside or inside the harvesting area.
    Note: Never turn the machine off till work flow has been concluded, otherwise residues volume inside the machine increases.

 Combine maintenance

Periodic maintenance items

• Every 8 work hours or daily: Lubricate all points specified in page 28.
• Lubricate all chains with the oil recommended in page 31.
• Check nuts and screws torque, fastening and components condition in ge-neral.
• Check all hydraulic connections.
• Check and clean the pickup unit, vibrating sieve (located under the Combi-ne), screen around the threshing cylinder and fan of the cleaning system. Check the alignment between pulleys. See page 30.

Every 50 work hours or weekly:

• Check the gearboxes oil level. See page 26.
• Check the tires pressure according to page 35.
• Check and adjust, in case there is need, the chains and belts stretch, ac-cording to pages from 29 to 32.

Every 200 work hours or every 800 ha gathered:

• Check the ball bearings for noise level and heating.

Every 1,000 work hours or every 4,000 ha gathered:

• Check and replace, in case there is need, the spring plates of the vibrating sieve.
• Change the gearboxes oil. See page 26.

Note:

The first change of such oil should be done after the first 50 work hours.

After the harvest or work day, see the Combine preservation:

• See page 35.

Oil change

Follow the procedure below to change the oil in all gearboxes, according to the change interval specified in Table 8.1.
Note:
Change the oil after a long running period of the gearboxes. This way, oil drainage is more efficient.

• Remove the level plug (I) and, using a flexible hose, drain the oil into a proper recipient.
• Remove the plug or breather (II) and fill up with the recommended oil up to the level reaches the low edge of the level plug (I).
• e-put the plugs and keep the breather always unobstructed.

Oil recommended by Colombo – Class SAE 140

Grease lubrication points

Apply grease in all points specified in page 28 using a grease pump (1).
Lubricate right after a Combine work period while it still hot because this way the grease will flow better between the movable parts.

Recommended grease

Lithium complex base grease with extreme pressure pro-perties: Grade NGL II. Drop point: Greater than 260o C.

Grease points identification

Belts maintenance

Check the belts stretch (deflection value) in the interval specified in page 25, pres-sing them with your thumb on the central point between the pulleys. Also check the belts general condition. In case they present excessive wear, drying or loose fibers, replace them.
Keep the belts always clean, free of greases and oils because such products harm their composition causing premature wear. The table below presents the charac-teristics of all the machine belts.

Procedure for adjustment

Adjust the belts stretch using the respective stretchers as follows: To adjust the turbine drive belt, release the nut (2) and turn the nut (3) to stretch or loosen the belt, according to need. After reaching the deflection recommended above, re-
-tighten the nut (2). To adjust the pickup platform belts, release the 4 nuts (2a) and turn the nut (3a) to stretch or loosen the belts, according to need. After reaching the deflection recommended above, re-tighten the nuts (2a)

Alignment between pulleys

Misalignment between pulleys also causes belt premature wear. To check the alignment, lean a ruler face against the pulleys face according to the example below.

Alignment between pulleys is done through their displacement on the shaft they are fastened on. To displace them, release the fastening screw or remove the key, according to the case. After adjustment, fasten the pulley again.

Belt replacement

Before removing the belts, loose them using the stretchers (previous page). Always install genuine new belts, according to specification recommended by the machine manufacturer. After installing new belts, adjust the stretch according to previously described. Also check the alignment between pulleys, according to described above.

Warning:
Where there are belts working together (on pulleys of two or more channels), never replace only one of the belts. Always replace the WHOLE SET, even if only one of the belts is damaged.

Chains maintenance

Chains require some simple care, aiming to prolong their useful life, once they work in a dusty environment and many times it is abrasive dust. A chain working with improper stretch, besides having premature wear, it causes noise and can even get out of the gear. Check the chains play in the interval specified in page 25, pressing them with your thumb on the central point between the gears. The table below identifies all the machine chains.

Procedure for adjustment
Adjust the play using the stretching rollers (4). For that, loosen (do not remove) the nut located in front of them and move them upward and downward, according to need. After reaching the play recommended above, re-tighten the roller nuts.
For the other chains, use the same procedure
D – Cleaning and lubricatio
Keep the chains clean. Wash them with a brush and kero-sene or diesel oil, whenever there is need. Following, dry them with compressed air or by natural outflow.
If possible, apply a thin coat of chain special oil, such as the MAXLUB ND-03.

Note:
Do not use grease in chains because it does not penetrate in links and pins, besides making easier dirt buildup. Joining link clamp s should be with their openings toward the opposite side of the chain rotation direction, according to side figure.

E – Correct mounting of the joining links of a chain
Joining link clamps should be with their openings toward the opposite side of the chain rotation direction, according to side figure.

Perform a full check inside the machine. Manually remove residue buildup or branches from the threshing cylinder screen (5), vibrating sieve (6), rear sieves (7), pickup unit sieve (8) and fan (9). Also check the sieves (5, 6, 7 and 8) condition, check whe-ther they are damaged. To clean the fan (9), release the eight nuts (9a) and remove the cover (9b). After cleaning, put the cover (9b) back and following put and tighten the nuts (9a).
Weekly wash the machine with water jets and allow it to dry in the sun.

Warning: Always turn the machine off to clean it.

Grain elevator maintenance
A – Check
Check whether the mugs (10) are in good preservation conditions and whether the nuts (11) are well tightened. Also check the preservation conditions of chain links (12). In case they present excessive wear or play, they should be replaced to prevent troubles during the harvest. Remove the low checking cover (13) of the elevator to clean the mugs (10).

Stretch adjustment and centralization

Loosen the nuts (14) of both stretchers (15). Turn both nuts (16) up to the bearings (17) are leveled, providing alignment to the mugs (10). To test the leveling, move the elevator in low rotation and watch the mugs (10) positioning in relation to its walls. Measure “A” (distance between the low and upper mugs) should be the same on both sides of the mugs (10), according to side image.

Tires pressure check

Tires pressure check largely determines their useful life duration. Check the pressure in the interval specified in page 25 and, in case there is need, adjust the pressure with the tires cold according to the table below.

Machine preservation in the period between crops

Preservation is as important as preventive maintenance. Therefore, shelter the Combine from the weather and protect it from the corrosive effects of some products. Take the following care:

• Lubricate all the points specified in page 28.
• Clean out all the residues of product that remained inside the machine, inside the grain tank and on the pickup unit.
• Fully and rigorously wash the Combine and allow it to dry in the sun.
• Repaint the points where there is need, preventing rust stains.
• Spray the movable parts with oil or any other lubricant.
• Remove the chains, wash them with kerosene or diesel oil and after that, dry them with compressed air or natural outflow.
• At last, lubricate them with a thin coat of chain special oil such as MAXLUB ND-03.
• Very important: Always keep the machine in a dry place, sheltered from sun and rain. Without such care, there is no preservation.
• Remember: The period between crops is the best moment to perform preventive maintenance in the machine, leaving it in perfect conditions for the next harvest.

When returning to work, observe the following items

• Re-tighten nuts and screws in general.
• Re-put the chains and adjust their play according to instructions in page 32.
• Check the adjustments for operation described from page 20 of this Manual.
• Allow the machine to run (idle) for some minutes and then, after turning it off, lubricate all grease points and chains.
• Check the gearboxes oil level and fill it up in case there is need. Check the tires pressure according to page 35.
