23 Safety The BIG PACK Baler must be driven by a tractor with at least a 65 kw (85 bhp) power output. The BIG PACK Baler is hitched to the trailer coupling or the swinging drawbar. The swinging drawbar is fitted with a height adjustment feature so that the big pack baler can operate in a horizontal position. The drive to the BIG PACK is via a PTO shaft which transmits the torque from the tractor via a flywheel mass () to a straight bevel gear pair (). The maximum input speed of 000 rpm may not be exceeded, as there is a risk of the machine being damaged. The PTO shaft is equipped with a wide angle joint on the tractor side. The operating instructions for the PTO shaft are located at the PTO shaft. Before putting the big pack baler into operation, the operating instructions for the PTO shaft should also be read. These detail in particular the shortening of the PTO shaft as well as any repair and maintenance work. The m (,4 m) wide pick up () collects the crop cleanly. A height-adjustable baffle plate () ensures error-free collection and helps prevent blockages. The baling material is carried via filling augers (), which are on the left and right side of the pick-up, to the packer drum () or the cutting rotor (4) and blades (5). The pick up can be raised and lowered with the tractor hydraulics. The feeler wheels on the pick up are heightadjustable so that the optimum pick up collection height is always reached. The conveyor feed packers (4) fill the conveyor channel. The crop is pre-compressed by the action of the packers. The sensor rake (6) detects the pressure in the conveyor channel. The sensor rake swings back once a preset pressure is obtained. In the bale channel the pre-compressed crop is pressed to a highly compressed big pack by the plunger (6). The length and of course the density of the pack are infinitely variable. Big packs can therefore be produced for the most varied of requirements. The plunger thrust is controlled automatically by the hydraulic cylinder (9) at the bale channel shutters. When the set pack length has been reached, the knotter mechanism star wheel projecting into the bale channel is actuated. The Big Pack 88 is equipped with 4 knotters (7) and the Big Pack 7 and 8 with 6 knotters (7). The packs are deposited by a two-part pack chute (0). II -

24 Safety Special Equipment Roll-type crop guard: A roll-type crop guard can be used to pre-compress the windrow during the pick-up and to guarantee even loading of the machine. Swath distributor: A swath distributor is available as an extra to ensure an even feed of the bale channel with narrow swathers. Hydraulic folding bale chute with rollers: Especially when using the big baler for baling grass silage, the rollers in the bale chute make it easier to deposit the bales. Compressor: If hydraulic brakes are used on the big baler, a compressor can be installed as an extra for knotting device cleaning. MultiCut: The MultiCut cutting system is available particularly for silage recovery or when short bailing material is needed. A size reduction to as little as 45 mm is possible using this. Wide pick-up: To better deal with wide harvester-thresher swaths, the big baler can optionally be delivered with a wide pick-up (.4 m). Hitching export versions: Depending on the requirements of the respective country either a pivoting drawbar eye or a hitch coupling is available. Double knotter When harvesting silage, the double knotter has some advantages over the single knotter. The twine is not placed in the knotter during baling. This reduces the wear on the knotter and the twine during baling. The tying mechanism with the double knotter is however more time-consuming during set-up, maintenance and when resetting. Automatic centralised lubrication system: The centralised lubrication system provides the most important greasing points with lubricant (knotters, plunger with connecting rod, bogie axle, gauge wheels and pick-up). Electric bale length adjustment: Bale length can be varied continuously during the baling process using the display of the control unit. II -

25 . Preparing the Big Pack Baler. Special Notes on Safety Preparing the Big Pack Baler Particular care is required when attaching the big pack baler to or detaching it from the tractor. There must be nobody between the tractor and the big pack baler. After coupling, switch off the engine and remove the ignition key. Apply the flywheel brake. When carrying out care, maintenance, adjustment and repair work, always switch off the PTO shaft, switch off the engine and remove the ignition key. Only put the big pack baler into operation when all protective devices have been attached and are in the correct positions. The big pack baler may be operated with a maximum PTO shaft speed of 000 rpm. Only PTO shafts specified by the manufacturer with the correct overload coupling and free wheel facility may be used. The PTO shaft may only be attached and detached when the tractor PTO shaft is switched off, the engine is switched off and the ignition key is removed. Lay hoses and connection cables in such a way that they are not under tension and do not come into contact with the tractor wheels when going round corners. Check hydraulic hose lines regularly and replace if damaged or aged.

43 Comfort Controls 4.6 Basic setting Two sensors on the front part of the frame detect and amplify the density force and transmit it to the on-board computer. The on-board computer interprets the signals and then controls the pressure in the hydraulic cylinders of the bale channel shutters. At the same time, the signals are transmitted to the control panel. They appear as a bar graph on the display to the left (b) and right (c) of the indicator for the baling pressure (Pmax-Mode) (a) or desired density force (Automatic-Mode) (a).

The actual density force can be seen from the pressure gauge. The central bar graph (a) and the lateral bar graphs (b = LH) and (c = RH) (pressure exerted on the bale) are independent from each other. That means that the lateral bar graphs can show higher or lower values than the central bar graph (Pmax target value). If the lateral bar graphs reach their maximum height, that means that the machine is operated at the limit of capacity and pressure cannot be further increased up to the target value (overload protection feature).

Pressing the Pmax key (e) activates the automatic mode (the LED of Pmax key (e) goes out). b a c d Prog Quit Contrary to the Pmax mode, the keys and Pmax are not used to determine a fixed density value, but a target value between 0 and 00 per cent. The machine is trying to control the density force by increasing or reducing the value until the density measured inside the bale (bar graph (b) = LH side and bar graph (c) = RH side) complies with the target value (central bar graph (a) (average value of the RH and LH bar graph identical to the target value). 4 e # BP-VFS-06 The control only operates when the feed packer drum supplies crop to the ram. If no crop is supplied (at the headland or when idling for example) the current pressure will be maintained. During operation the on-board computer controls the contact pressure of the bale chamber shutters independently so that the density force pre-selected by the comfort controls is obtained. In the process, the pressure on the manometer may fluctuate considerably! While the bale chamber is being filled, you should never increase the density value or switch to automatic mode. This rule must be strictly observed to prevent the deformation of the bale chamber shutters. IV - 6

Lateral Adjustment of the Needles Insert the needles () centrally between the clamping brackets and the needle yoke, turn them towards the needle slits and screw tight with screws (). To be able to carry out the adjustment, the binding process is initiated manually and the needle yoke manually turned up in the working direction at the flywheel mass. When raised, the needles must just laterally touch the left and right hand sides of the knotter frames. To correct the lateral distance, the screws () are undone and the needles laterally positioned with the adjusting screws (). Always make sure that the screws are all tightened up firmly again after making the adjustment. BP VI -

58 Settings 6.. Height of the Needles on the Knotter Single Knotter To adjust the height of the needles (4) when these are entering the knotting system, start a binding process and then turn the flywheel manually in the normal sense of operation until the lower roller of the needle point is located above the cleaning disc of driver (). Distance a from the lower edge of the needle roller to the top edge of the cleaning disc should be equal to - mm if twine is installed. If this dimension should not be availble, an adjustment can be made by using the set screws (7). When entering the knotter, the needles should slightly touch the knotter on the RH side. Any required side adjustment of the needles can be performed using the set screws (6) (see section 6..). After adjustment it is essential to check that the screws (6) and (7) are properly locked. a b Needles' Upper Dead Centre If a binding process starts, the needle yoke is set in motion by connecting rod (). To adjust the upper dead point of the needles, the needle yoke must be moved to its highest position (dead point). The needles (4) project from the knotter. Distance b from the top edge of the driver disc () to the center of the lower roller should be equal to x mm if twine is installed. If the adjustment should not be correct, shorten or lengthen needle connecting rod () until the required value is available.

59 Settings 6..4 Needles in Idle Position If the needle yoke is in the idle position, i.e. the crank arm () and the needle drive connecting rod () are extended, there must be a distance c = 0-0 mm between the cross tube of needle yoke (4) and brake (). 4 c If an adjustment is required to reach dimension c, move brake () relative to the set of holes (A). If dimension c cannot be reached by moving the brake, check the position of the needles relative to the knotters (see section 6..). A BP-VFS-08 VI -

60 Settings 6..5 Needles Relative to the plunger To set the needles relative to the plunger, the drive PTO shaft for the knotter shaft must first of all be dismounted. The plunger is turned manually in the working direction at the flywheel mass until the crank arms and the piston rods are overlapping each other (i.e. the baling ram is at the front dead centre). The knotter gear is then turned until the coloured marking on the knotter shaft crown wheel is aligned with the upper rear edge of the knotter gearbox. After the adjustment has been made place the PTO shaft for the knotter shaft back in position and secure. Check the settings as described in the following chapter. 6 5 BP-VFS-09 Checking the Setting of the Needles Relative to the plunger To be able to check the setting of the needles relative to the plunger, the binding process is initiated. Before checking the dimensions it is necessary to release needle yoke brake (). To do this: Release nut (4) on the RH and LH machine side. a The plunger () is manually turned in the working direction at the flywheel mass until the tips () of the binding needles are at the same height as the ram blade. In this position the needle tip must be covered by the plunger, with the dimension a = mm. If this is not the case the setting must be corrected by altering the position of the knotter drive PTO shaft. BP Adjust the length of spring (5) to 0 mm by tightening nut (4). 5 4 BP-VFS-0 VI - 4

61 Settings 6. Twine Bar (Single knotter) The twine bar () draws the twine down from the needle and presses it against the knotter hook. If the twine is not taken by the twine bars, the knotter hook cannot take up the twine. BP-VFS Adjusting the Twine Bar Initiate the binding process manually (see chapter "Initiating the Binding Process Manually"). Turn the flywheel in the working direction. The needles move upwards. At the same time move the twine bars over the openings through which the needles transport the twine to the knotter. If the twine bars () are in the middle of the openings, the distance from the tip of the twine bar and the inner side of the needle () must be "b" = 5 mm. 4 BP-VFS-0 The adjustment is made by undoing the screws () and (4) on the twine bar (). Shift the twine bar in the slot until the dimension "b" = 5 mm. 4 BP-VFS-0 The setting for the distance at the side "a" is adjusted at the control rod assembly (5) for the twine bar (). To make the adjustment undo self-locking nuts (6) and take off the ball head (7). Twist the control rod until the dimension a is set at a = 0 5 mm. When the twine bar is pressed in the direction of the slot, the a dimension must still be maintained. Tighten up the self-locking nuts again BP-VFS-0 VI - 5

62 Settings 6.4 Adjusting the twine brake (Single knotter) The twine brakes () are located below the twine boxes. The adjusting screws () keep the baling twine () under tension. The various types of baling twine may have different frictional properties. The tensile stress of the skein must be checked when the type of baling twine is changed. The level of the tensile stress on the twine should be selected so that the twine tension springs do not touch the swing angle. The X dimension depends on the selected baling twine and must be established individually by checking the skein. Exceeding feed tension of the skein may cause knotter faults and puts excessive stress on the components involved. BP-VFS-04 Checking the Tension:. Thread the twine as specified.. Initiate the knotting process manually.. Turn the big pack baler's flywheel manually in the working direction until the binding needle has reached its upper dead centre. 4. Draw out approx. 00 mm of twine and cut. 5. Pull the skein slowly and evenly until the twine tension springs reach their highest position under the channel. 6. While holding the twine, the twine tension springs must remain in this position without the twine being able to be tightened by the brake. 7. With slight increase of the tensile force the brake must allow the twine to slip through. x BP-VFS-06 VI - 6

63 Settings 6.5 Plunger Setting The guide rollers for the plunger must carry uniformly. The gap between the plunger blade and the blades in the bale channel must be uniform over the whole width of the ram. The bale chamber is equipped with two blades (6). The plunger () on the Big Pack 7/8 is equipped with seven blades (5). The plunger () on the Big Pack 88 on the other hand is only fitted with five blades (5) due to the smaller width of the bale chamber. Adjusting the plunger blades a The plunger blades must be set precisely to obtain a smooth surface on the underside of the pack. To adjust the distance to "a" = mm the height of the plunger can be adjusted with the eccentric sleeves () on the guide rollers. After separating the two halves of the clamp bedding (), the eccentric sleeves are turned to raise and lower the plunger. After making the adjustment, the tighten the two halves of the clamp bedding again. Make sure that the guide rails (4) and the guide rollers do not become dirty. This can lead to increased wear and an imprecise height setting of the plunger BP Guide Rail Cleaning There are cleaning rails attached to the four plunger rollers (), which clear the plunger guide rails of deposits of dirt. To make the adjustment undo screws () and set the cleaning rails to the dimension a = mm. Tighten up the screws again. The cleaning rails () must tilt easily around the roller axle! a BP VI - 7

64 Settings 6.6 Setting the packer Relative to the Baling Ram Turn the packer manually in the working direction until the small guide roller () of the packer () is visible in window () on the left hand side of the machine. Lift up the guide roller with a mounting lever (4) so far that it meets resistance. This ensures that the packer drive is engaged. The packer is then turned forwards until the packer edge (8) which advances the feeder edge (9) lines up with the setting mark (0). Lock the packer in this position with a mounting lever. 4 BP The central point of the packer fingers (8) should not project beyond setting mark (0). BP-VFS-095 Dismount the protective plate from the bracket (6) on the left hand side of the machine. Remove the roller chain (5) from the packer gearbox (7) drive shaft. Move the piston rods into the exrended position (rear dead centre). The packer (fixed into position with the mounting lever) and the ram are now in position for the adjustment. Place the chain coupling roller chain (5) in position and secure. Attach protective plate and remove the mounting lever. Turn the machine manually through one entire revolution at the flywheel. The packer must be adjusted when packer gearbox or the chain coupling connection chains are replaced. BP VI - 8

65 Settings 6.7 Setting the clutch. Adjust the adjusting screw (4) so that the clutch switch ratchet (8) sits B = 6-8 mm on the middle of the roller (9) when the clutch is switched off.. If the anvil (5) sits on the adjusting screw (4), the rear of the back holder rake () has to stand parallel to the back wall of the feed packer channel. You can set it at the threaded rod () (arrange measure of A = 48 mm).. After rotation the roller (6) will drop down the outside margin of the pulley (7). When the back holder rake pulls back the anvil will apply to the adjusting screw. In this position the top of the back holder rake () still has to reach 5-0 mm into the feed packer channel. You can set it with the adjusting screw (). A B 8 BP-VFS Damper equipment 6.8. Lateral setting of the damper equipment To compensate tolerances because of welding and adaptation the damper equipment is adjustable. Checking the settings: Press the anvil (5) against the adjust screw (4). In this position there should be a gap of 5-7 mm to the back from the strech screw for the pressure spring (0) in the slot () of the anvil. To correct the adjustment undo the screws () and correspondingly displace the damper equipment. BP-VFS Setting the damper equipment The damper equipment prevents the anvil from switching on the VFS-clutch through its own movements. The adjustable tension of the pressure spring (0) depends on e.g. the condition of the brake (wear grade, paint, rust). To check the spring's tension you have to actuate the back holder rake (). For that reason put some feeder in the big baler. If the back holder rake swings back again (at full number of revolution), the anvil (5) is allowed to bounce back from the adjust screw (4) max. - mm. If the anvil bounces back further you will have to increase the tension of the pressure spring (0). If the back holder rake swings out, the anvil has to arrive at the adjust screw (). If not, reduce the spring tension. VI - 9

66 Settings 6.9 Setting the sensibility of the actuator 4 The spring () is responsible for bringing the back holder rake into its swing position again after the feeder insertion (over the anvil (5) and the threaded rod ()). The anvil (5) therefore has to arrive at the adjust screw (4). 5 The arrange measure is swing length C = 0 mm. The tension of the swing should be increased, if - the end position of the back holder rake and the anvil cannot be reached (see chapter 6.8.) - the filling of the press channel's height is not sufficient. -> Badly filled baler corners mostly result due to bad forms of swathe or onesided driving conditions C BP-VFS-09 Excessive spring tension can cause a blockage of the packer and therefore reduce the output. Setting of the spring of the zeroizing device A When the zeroizing device is in its unlatched state, the spring should be tensioned to a dimension of a = 85 mm Adjusting the VFS brake setting: BPVFS The spring in the brake of the VFS circuit should be tensioned to a dimension of b = 65 mm. A 6.0 Adjusting the Flywheel Cleaning Mechanism (only Big Pack 88) BPVFS Even small deposits of dirt in the interior of the flywheel () can lead to imbalances. The setting of the plastic bar () should therefore be checked regularly.
