7 1. General Safety precautions These instructions and safety notes in this instruction manual must be followed. Safety distances The safety distance to the seed drill while in operation is 4 metres. Persons must under no circumstances be on the seed drill while it is running. Safety when lifting the seed drill The indicated lifting eyes should be used when lifting the seed drill and when carrying out repair of the seed drill s main frame. Safety precautions concerning guards Guards for chains, gear wheels and rotating shaft ends etc. must be fitted to comply with the required safety regulations. Loose guards, which include calibration trays and seed hopper lid, should be fitted and closed when the machine is running. The agitator shaft in the hopper is not shielded. Therefore, to avoid injury, hand stirring of the sowing material whilst the machine is running must be avoided. Fixed guards should be removed and fitted using tools. Safety precautions whilst driving When driving on public roads, road traffic laws concerning lights, safety, etc. should be followed. Lift arm pins and top link pins should be properly secured in order to avoid accidents. On safety grounds, marker arms should always be locked in position when driving on public roads. Locking is carried out using lock fittings which are mounted on the locking pin and secured with a ring pin. See fig. 2M and 2N. Safety precautions when parking Always place the seed drill on firm, horizontal ground when it is removed from the tractor. Ensure that the support legs are mounted and secured by the locking pin. Safety when cleaning Cleaning and maintenance of the seed drill should only be carried out when the machine is not running. Safety precautions concerning hydraulics Hydraulic systems with a working pressure of up to 200 bar must be treated with care. When carrying out repairs, the hydraulic system must be without pressure. Air in the hydraulic system can lead to incorrect functioning of the machine, and thus should be expelled before the machine is used. Safety precautions concerning tightening Tighten all bolts after the first 25 hours of operation. All bolts should be subsequently tightened before the start of each season. Product liability Nordsten s product liability covers machines which are defective on delivery. Product liability no longer applies if modifications are made to the seed drill or its accessories without Nordsten s explicit written permission. It is also a condition of the product liability that the seed drill is only used for purposes described in this instruction manual or for purposes which have Nordsten s permission. 1.4 Version NS 4000 B

8 1.General Safety precautions Finally, it is also a condition that the seed drill is used with all fixed guards fitted. Version NS 4000 B 1.5

9 2. Mount. and adjustment Commissioning the seed drill Immediately after receiving the drill, it and any extra equipment should be checked to ensure that the items received are in accordance with the order and that there are no defects or missing parts. Any claims should be immediately forwarded to the dealer. Commissioning driving wheel, gearbox, agitator shaft and sowing shaft are correctly adjusted. This is particularly importtant if extra equipment with chain drive has been fitted. Any necessary adjustments should be carried out as described in section 5. Chains and linkages should be lubricated with oil. In the case of damage occurring during transport, claims should be forwarded to the transport firm used. Otherwise reference is made to Nordsten s usual terms of sale and delivery. The coulter settings - and thus their relative spacing - may have changed during transport. The coulter settings should therefore be checked (see section coulter spacing) and any necessary adjustments carried out as described. Check that the chains between the Version NS 4000 B 2.1

10 2. Mount. and adjustment Coupling Mounting of tank unit on cultivation equipment We further refer to the spare parts list for coupling kit. The two hooks are mounted on the rear sides of the headstock of the cultivation equipment. See fig. 2A. On the Howard power harrow HK 32 the hooks are integrated in the machine and have, therefore, not to be mounted. The bracket to connect the tank unit to the top of the headstock is now mounted. See fig. 2B. The tank unit should be situated on a flat surface. The supporting legs are placed so that the cultivation equipment passes between the two legs. Fig. 2A. Mounting of hooks. The cultivation equipment can be placed under the tank unit and lifted up so that the suspension points of the tank unit are caught by the hooks. See fig. 2A and 2C. A pin is placed in the top bracket and locked by a ring pin. See fig. 2B. Locking bolts are mounted to lock the tank unit. See fig. 2C. The machine is lifted and the supporting legs can now be re-moved. Fig. 2B. Foremost top bracket. Fig. 2C. Lock bolts. Machine with hydraulic driven blower In the case of an hydraulic driven blower the following demand is made on the hydraulic system of the tractor. The blower requires up to 30 l/min at a pressure of about 125 bar. The hydraulic system of the tractor must be able to produce 8 kw continuously for runing the blower. On newer tractors it is possible to adjust the oil quantity on the individual oil outlets. The oil flow is adjusted at the tractor valve first, so that the values stated for blower pressure are observed. Max. 60 mbar. 2.2 Version NS 4000 B

11 2. Mount. and adjustment Coupling Fig. 2D. Hydraulic driven blower. On tractors without the possibility for controlling the flow of oil from the external hydraulic spool valves, the air pressure can be set on the regulator valve. See fig. 2D. On connecting hydraulic hoses the probes should be cleaned before installing. Connect the red hose P (pressure) to the tractor's external service. The green hose R (return) must be fitted to a free flow return (pressureless). On tractors without a freeflow return the dealer must establish one. Set air pressure as follows: 1. Make sure valve is fully open (screwed out). 2. Run tractor with spool valve in flow at an engine speed equal to pto output. E.g rpm PTO speed. 3. Screw in adjuster to get recommended air pressure. On drills fitted with a PTO driven fan, a gearbox is mounted on the output shaft of the power harrow and is driven at 1000 rpm. The PTO shaft is connected to the gearbox splined shaft and locked with a bolt. The cardan joint on this end of the PTO shaft is lubricated for life. The other end of the shaft mounted to the drill should be lubricated after evry 16 hours work. See fig. 2F. The V belt tension for the fan drive is via an idle tension roller. See fig. 2G. Fig. 2E. Mounting of gearbox. Fig. 2F. PTO shaft. On Howard HK power harrows the levelling board handles are replaced with hexagon nuts. See fig. 2G. Fig. 2G. Tension roller. Version NS 4000 B 2.3

12 2. Mount. and adjustment Coupling Mounting of coulter kit on cultivation equipment We further refer to the spare parts list for coupling kit. A bracket is mounted on each end of the packer roller arm of the cultivation equipment. See fig. 2H. The coulter kit can now be mounted with link arms, top link and support spindles. A cross bar between the link arms is mounted. The top link is now adjusted to place the coulter frame horizontal. Hoses from the seeding houses are installed, passing under the narrow foot board and to the distributor heads. Remember to connect the seeding hoses, which are fitted with a coupling to reduce the sowing rate, to the distributor heads equipped with flap valves for tramlining. Fig. 2H. Mounting of coulter kit. Fig. 2I. Foot board. 2.4 Version NS 4000 B

13 2. Mount. and adjustment Row distance The distance between the coulters is measured directly on the coulters themselves - and thus not on the suspension arms. The use of a measuring implement with the actual row spacing marked is recommended. Remember to tighten all bolts after adjustment. Fig. 2J. Clamp with bolt. Row distance Fig. 2I. Row distance. Changing and adjusting the row spacing can be carried out by moving the suspension arms and clamp for each coulter sideways on the coulter bar. This can be done after the bolts under the clamps have been loosened. See figure 2J. Version NS 4000 B 2.5

14 2. Mount. and adjustment Marker shifter Markers The seed drill is fitted with hydraulic markers. A single-acting hydraulic take-off from the tractor is used which activates a shuttle valve (see fig. 2K) in the following way: On supplying hydraulic pressure to the marker system, both markers go to vertical. By removing hydraulic pressure from the marker system, one marker will move into its working position. Shifting between the markers (i.e. between left and right) is done by supplying, and then removing, hydraulic pressure from the system. If both markers are required in their working position, the marker system is activated in the following way: The marker which is in its working position is raised about 1 metre. The hydraulic pressure is then removed from the system, after which both markers will move into their respective working positions. Marker arms, shear bolt The marker arms are equipped with a shear bolt which is released when overloaded. Carrying an extra shear bolt (M6 x 75 grade 8.8) is recommended. See fig. 2L. Marker arms in transport position When transporting the seed drill on public roads, the marker arms must be locked up. The locking can be made by lock pins which are put under the support of the marker arms. The lock pins are secured with a ring pin. See fig. 2M. In order to reduce the transport height on 4,0 m machines the marker arms are articulated. Both in the "folded" position (during transport) and in the working position the link must be locked with a locking pin, secured with a ring pin bolt. See fig. 2N. Fig. 2K. Shuttle valve for marker. Fig. 2L. Shear bolt. Fig. 2M. Locking pin for transport. 2.6 Version NS 4000 B

15 2. Mount. and adjustment Hydraulic hose, marker The hydraulic hose for the marker arms is connected to the tractor. If the tractor is provided with an outlet for an assistor cylinder, this outlet is used. If the tractor is not provided with such an outlet, the hydraulic hose is connected to the outlet of a singleacting remote cylinder. Removal of coulter kit Always park coulter kit and tank unit on a horizontal and firm ground, when disengaging. Removal Removal of tank unit Supporting legs are put onto the tank unit. The hydraulic hoses and any wires for light and tramlining are disconnected. If necessary the air hoses from the cultivation appliance are loosened. In the case of PTO driven blower the pulley (behind blower) and the tension arm are loosened. Then the belts can be removed. See fig. 2F. Lock bolts and pin fig. 2B and 2C are removed. Supporting legs are put onto the coulter bar. Fig. 2N. "Folded" marker arm. Hoses for the distributors are removed. Remove the guard on the side of the tank unit to remove the long cassette for the land wheel. Link arms, top link pin and spindles are removed. Version NS 4000 B 2.7

17 2. Mount. and adjustment Tramlining Tramlining Agro Tram 2100 can now be mounted for controlling tramlining. We further refer to instruction for Agro Tram On two distributor heads hydraulic cylinder for opening and closing of the outlets for the distributor is mounted. See fig. 2Q. A stainless disc closes two outlets in the distributor head. A solenoid valve for control of tramlining is mounted on the marker shuttle valve. See fig. 2R. A wheel sensor is mounted on the input shaft on right side of the seed drill. See fig. 2S. Fig. 2Q. Flap valve. Fig. 2R. Wheel sensor. The sowing rate is reduced automatically by a solenoid clutch on the side of the seeding housings. See fig. 2T. The clutch stops the outer roller on left side, when tramlining. See fig. 2T. Fig. 2S. Solenoid clutch. Fig. 2T. Sensor for control of "tracknumbers" On the marker arm a sensor is mounted for control of "tracknumbers" for the tramlining. See fig. 2T. Version NS 4000 B 2.9

Right and left cylinders are connected to one of the hydraulic hoses, in a way that leads the hoses through the eyes on the harrow tines. See fig. 2X. Fig. 2X. Right cylinder. The wire from the solenoid valve is connected to the 7 pin socket plug, on the coulter frame. Brown wire is connected to terminal 7/58L and blue wire to terminal 4/R Version NS 4000 B

19 3. Adjustment General Before sowing begins, the following should be carried out: - Test sowing of the drill - Setting coulter pressure/sowing depth - Setting the drive wheel - Setting the markers. Test sowing of the drill Test sowing includes both a calibration depending on the weight/size of the seed (1000 grain weight), and the adjustment of the sowing rate per unit area. Agitator shaft The agitator shaft always runs. It is not necessary to disengage the agitator shaft when sowing large seed, e.g. peas and beans. Bottom flaps The bottom flaps should be as close as possible to the seed wheels without damaging or squeezing the seed. The bottom flaps can be adjusted using the handle at the end of the hopper. See figure 3B. The scale setting for different seed sizes should be as follows: Fine seed : 1 Corn : 2-3 Peas, etc. : 3-6 Table 3A. Adjustment of bottom flap position. Fig. 3B. Handle for bottom flaps. Test sowing Seed housing shutters The shutters must not be used for adjusting the rate of sowing. The shutters should always be completely open or closed. If you wish to start sowing with half the sowing width, the shutters at one side can be closed. Emptying of machine The calibration bags are mounted under the seed housings and the bottom flap handle is turned backwards. Exchange of seed wheel See special crops chapter 3.4. Fig. 3C. Seed housing shutters. Version NS 4000 B 3.1

20 3. Adjustment Test sowing The test sowing is carried out to ensure the correct sowing rate, and is carried out as follows: The correct sowing rate can be adjusted using the formula: NO. OF PLANTS PER M² X TCW = KG / HECTARE GERMINATION PERCENT IN THE FIELD TCW = 1000 grain weight After this preliminary adjustment the test sowing should be carried out. Gear cassette position The gearbox allows continuously variable regulation of the seed roller s speed. The gearbox has two different working ratios: a low and a high, the high being a direct continuation of the low. By turning the gear cassette on the side of the gearbox, the high or low ratio can be selected. The low ratio is engaged when the cassette is positioned with the largest wheel upwards. This ratio is used for sowing small seeds such as rape and clover. The high ratio is engaged by positioning the casette with the largest wheel downwards. This ratio is used for grain and larger seeds. Test sowing The position of the cassette is chosen according to the sowing table in this instruction. Table 3O page The cassette can be rotated only after removal of the ring pin in the centre. It is important to remember to replace the pin after changing ratios. Scale setting, Vario-Exact gearbox Initially,the scale should be set to the correct sowing rate according to previous records or to the sowing table 3O on page 3.6. Fig. 3D. Cassette position, high (2). Fig. 3E. Scale setting. 3.2 Version NS 4000 B

21 3. Adjustment Blower The blower must not be run during the calibration. Bottom flaps under seed housings. The spring loaded bottom flaps under each seed housing are opened. See fig. 3F. The calibration bags are hooked below. See fig. 3H. Filling of seed Fill sufficient seed in the hopper such that the agitator shaft is still covered after a test sowing has been carried out. Fig. 3F. Bottom flaps below seed housings. Starting the seed flow Attach the test sowing handle and turn it clockwise until the seed flows from all of the outlets. Empty the contents of the calibration bags into the seed hopper. Turning the test sowing handle Turn the test sowing handle according to the table 3G below: 1/20 HA 1/10 Acre NS NS Table 3G. Turn the handle x number of revolutions per 1/20 ha. or 1/10 acre. Fig. 3H. Calibration bag. Test sowing Weighing Weigh the seed from the sowing tray(s) on an accurate pair of scales. Calculation of the sowing rate To obtain the sowing rate for 1 ha., the measured weight must be multiplied by 20. Adjusting the sowing rate If the calculated sowing rate corresponds to the required rate, then the machine is correctly adjusted. If the sowing rate is not correct, the following adjustment can be made by changing the scale setting. If a larger sowing rate is required, the regulating handle s indicator should be adjusted to correspond to a higher value on the scale. After adjustment of the scale setting, a new test sowing should be carried out. Version NS 4000 B 3.3

22 3. Adjustment Discrepancies in the sowing rate If the test sowing has been carried out carefully, the actual and calculated sowing rates should correspond exactly. If this is not the case in practice, then the cause could be that the test has not been carried out corrrectly or that an inaccurate pair of scales has been used. However, another potential cause of discrepancies is unusual soil conditions. Very wet or very loose soil can cause inaccurate rolling of the drive wheel. If problems are caused by the soil conditions, then a supplementary calibration test in the field is recommended. Test sowing in the field follows essentially the same procedure as the standard test sowing. However, instead of turning the test sowing handle through a specified number of revolutions, the seed drill is driven in normal working position a specified distance in the field with the calibrations bags mounted. See table 3I. 1/20 HA 1/10 Acre NS m 148 yds NS m 111 yds Tabel 3I. Drive x number of meters for 1/20 ha. or 1/10 acres. After test sowing The calibration bags are removed. The bottom flaps under the seed housings are closed. Blower The blower is engaged and the working pressure - read on the pressure gauge (fig. 3J) - is adjusted according to table 3O page 3.6. Fig. 3J. Pressure gauge, air pressure. Special crops Special crops When sowing special crops, certain precautions may have to be taken. Sowing of grass seed Sowing of grass seed requires special attention since the seeds can bridge in the hopper, thus affecting the actual sowing rate. This problem will be particularly acute if the hopper is exposed to vibration. It is therefore advisable to carry out test sowing with a limited amount of seeds in the hopper, and to avoid filling the hopper completely until in the field where sowing is due to take place. In addition, regular stops to manually stir the hopper contents is recommended in order to achieve uniform sowing. Warning Owing to the agitator shaft, stirring of the hopper contents should only be carried out when the machine is switched off. 3.4 Version NS 4000 B

23 3. Adjustment Special crops Sowing of small round seeds When sowing small, round seeds, such as turnip, white mustard and rape the fluted sowing wheels are exchanged for peg wheels with fine seed fingers. The sowing rate is reduced to 1/9 and at the same time waste is avoided since the seeds are only fed out by the pegs. Mounting of fine seed fingers The fine seed fingers are fitted by pressing them over the rollers. As the roller is turned, the fine seed fingers are pulled round to cover the roller. The fine seed fingers are shaped so that they are held in place. See figure 3K. Fig. 3K. Mounting of fine seed fingers. Disengagement of sowing wheels The covers above the seed wheels are disengaged by loosening the black thumbscrew at the front of the seed housing. The shaft connections on both sides of the seed housings are removed. The R-clips are removed. The R-clip at left side of the seed housing (at bearing) is removed and the bearing is pushed out of the bearing retainer. The sowing shaft can now be pushed fully to the right, and the bearing at right side comes out of the bearing retainer. The sowing shaft can now be lifted out of the seed housing. See fig. 3L and 3M. Fig. 3L. Removing of seed wheels/ shaft. Fig. 3M. Removing of seed wheels/ shaft. Mounting of peg wheels The solenoid clutch (for tramlining) is moved over to the peg wheel shaft. See fig. 3M and 3N. Fig. 3N. Sowing shaft with fine seed fingers. Version NS 4000 B 3.5

24 3. Adjustment Special crops The sowing shaft is put down onto the seed housing and the seed wheels are slid down into the seed housing. The bearings are pushed back in position and locked by an R-clip. The shaft connections are now completed. When peg wheels with fine seed fingers are used the bottom flap handle is placed in position Version NS 4000 B

25 3. Adjustment Sowing table Sowing table The sowing table shows the calibration of the drill and the scale setting for the required amount per hectare. Note that the sowing table is only a guide, a test sowing should always be carried out to check the scale setting.

26 3. Adjustment Couter pressure /sowing depth Coulter pressure/sowing depth In order to achieve the desired sowing depth on all coulters, it is necessary to adjust both the coulter pressure and the telescopic arms correctly. Coulter tightening The coulter adjustment can be adjusted individually for each coulter. This is done by changing the position of each spring by moving the chain one or more links on the coulter arm. With this individual adjustment it is possible to obtain an increased coulter pressure on the coulters working behind the tractor wheels. See fig. 3Q. The tension of the spring determines the sowing coulter s working depth in the soil. Note also that a too-high forward driving speed can also result in non-uniform sowing depth. Central coulter adjustment can be carried out on all coulters at the same time. Machines with a working width of 4,0 m are provided with two spindles. Central coulter adjustment is carried out by turning the spindle with the calibration handle or openend spanner. See fig. 3P. Fig. 3P. Central coulter adjustment. Fig.3Q. Individual coulter pressure. 3.8 Version NS 4000 B

27 3. Adjustment Adjustment of markers The markers are used to make a marker track. The track ensures that the outer coulter in one row is both parallel to and correctly spaced with respect to the previous row. Centre marking The seed drill has centre marking. Thus the distance from the outer coulter track to the marker track should be half the width of the seed bed plus half a row spacing. This adjustment can be carried out most easily by driving forward a few metres with the markers and the sowing coulters lowered into their working positions, such that the tracks can be clearly seen in the soil. Alternatively, the marker is set 3.0 m out, as measured from the centre of a 3.0 m seed drill, 4.0 m out on a 4,0 m machine etc. Marking track The marking track s width can be adjusted by turning the cranked marker shaft. See figure 3S. The narrowest track is obtained by turning the shaft downwards such that the marker is parallel to the direction of travel. The widest track is obtained by turning the shaft such that the marker is angled backwards with respect to the direction of travel. Fig. 3R. Centre marking. Markers Fig. 3S. Cranked marker shaft. The shaft should not be turned upwards or angled forwards with respect to the direction of travel as this can damage the shaft and give a poor track. The marker arms can be locked in a vertical position when driving on public roads or when driving close to fences, etc. Version NS 4000 B 3.9

28 3. Adjustment Following harrow Adjustment of following harrow The following harrow can be set for light or heavy harrowing, or placed in a transport position. Adjustment is carried out by turning the top links between the coulter bar and the harrow arms. Coarse adjustment can be made by moving the top links one hole in the upper marker arms. See fig. 3T. To obtain an optimum working effect it is possible to adjust the working angle of the harrow tine. See fig. 3U. Fig. 3T. Adjustment of harrowing depth. Fig. 3U. Working angle of following harrow Version NS 4000 B

29 4. Operation Generally During operation check continously that no sowing coulters are blocked. In order to avoid blockage of the coulters, it is advisable to only raise and lower the seed drill when driving forwards. Regularly check that there is sufficient sowing material in the seed hopper. Regularly check whether the actual sowing rate corresponds to the calculated rate. Both before and during sowing work, attention should be paid to the following.: that the lift arms of the tractor are correctly working. that that that that that that that the chain drive is correctly adjusted. seed rollers and bottom flaps are intact. bottom flaps are able to move freely - this can be checked using a finger or a thin shaft. coulters are intact (not worn out). the coulter arms are able to move freely and have the correct spring tension. the marker position is correct - check frequently. the air pressure is correct during sowing. Driving speed Emptying of seed hopper The seed hopper is emptied by opening the bottom flaps below the seed housings and by hooking on the emptying bags. The handle for the bottom flaps should then be pulled back completely such that any excess sowing material is emptied into the emptying bag. See fig. 3H. that that the coulter set is horizontal when the machine is lowered to its working position. the gearbox is in a good condition - gear wheels and gear bearings. During the sowing work the speed should be 5-8 km/h. In general speed should depend on the prevailing conditions and, in particular, oscillation of the machine should be avoided. Fig. 4A. Land wheel in transport position. that the oil level in the gearbox is visible in the oil-level glass (Vario-Exact). Version NS 4000 B 4.1

30 4. Operation Land wheel The land wheel must during transport be locked in a transport position. See fig. 4A. Lid The lid can be locked during transport. See fig. 4B. Fig. 4B. Lid. 4.2 Version NS 4000 B

31 5. Maintenance and lubrication Adjustment of chains Sprocket wheels for the adjustment of the chain should be loosened. The sprocket wheels should then be pushed upwards until the chains are at the correct tension, at which point the sprocket wheels should be tightened again. See figure 5A. Fine adjustment of bottom flaps The bottom flaps should be set to the highest position (position 1). Adjustment can then be carried out by turning the screw on the rear face of each bottom flap until the distance between the flap and the seed roller is 1 mm. See figure 5B. Fig. 5A. Sprocket wheels. Cleaning of seed outlets and sowing rollers Cleaning the seed outlets and seed rollers can be facilitated by removing the sowing shaft. See page 3.5. Fig. 5B. Adjustment of bottom flaps. Lubrication The gearbox oil must be visible in the level eye, otherwise it must be refilled with one of the following types of oil: Texaco Raudo HD 15 Raudo HD 22 Raudo HD 32 Shell Tellus Oil Tellus Oil (S) 32 Tellus Oil 32 Statoil Hydraway HM 15 Hydraway HM 32 ESSO Nuto H 15 Nuto H 32 All chains should be lubricated regularly. After each season, the chains should be cleaned in petroleum and then lubricated with oil. Before each new season all linkages and chain tighteners should also be lubricated. Version NS 4000 B 5.1

32 5. Maintenance and lubrication Wheel arm, marker arms, marker hub and the cardan joint should be regularly greased. See fig. 5C, 5D, 5E and 5F. For PTO driven blower the cardan shaft should also be greased regularly during the season. All bearings are self-sealed and do not require lubrication. Winter storage Careful cleaning of the seed drill after each season is recommended. The machine should also be prepared in plenty of time before the start of the new season. The seed drill should be protected from the elements during storage. To prevent vermin damage, during storage, it is important to fully clean the hopper and associated metering unit. Fig. 5E.
