Delivery and preparation of the machine Delivery and preparation of the machine Checking the machine On delivery, check that all parts of the machine are present and that they have not been damaged in transit; notify your dealer, importer or the manufacturer immediately of any defects found. NOTE For shipping purposes, some of the components may be supplied pre-assembled on the machine, while others may be fixed temporarily. Pre-delivery checks The machine leaves the Manufacturer with all parts in fully working order. In all cases, it is the Retailer's responsibility to check the following upon delivery to the User: the three-point attachment is correctly mounted, the grease in the transmission unit and the oil in gearbox are at prescribed levels, grease injected into the greasers is present, all adhesive safety labels indicated in the present booklet must be present and legible, screws and bolts must be securely tightened, EEC-compliant guards are provided, the machine must be free of imperfections upon general inspection. The Retailer must draw the user's attention to this manual and the drive shaft manual also provided, which must both be kept by the user throughout the machine's service life. The Retailer is also responsible for recommending that the user reads these manuals carefully. Preparation Risk of crushing and cuts! During machine preparation operations, observe the SAFETY rules, in particular: make sure that the machine is in a very stable position. Do not stand between the tractor and the machine during hitching or unhitching operations. If it is necessary to work in the area between the tractor and the machine, observe the safety rules (tractor engine switched off, Pto disengaged, tractor parking brake applied, key removed from starter switch, chocks placed under wheels of the tractor) Before hitching or unhitching the machine to/from the tractor, position the lift control lever in a position where it is not possible to operate it. Do not stand under suspended loads Take all necessary precautions to prevent injury or damage caused by accidental falls Reposition and securely fix in working position all those parts of the machine that were secured in temporary positions for shipment. Positioning the roller for work When supplied with the machine, the roller is secured in transport position; to position the roller in the correct working position, proceed as follows: 11

Delivery and preparation of the machine > Support the roller, observing safety rules > Unscrew the nuts securing the arms and remove the bolts Caution: suspended load hazard! > Move the arms and the roller into the correct position (see figure) and replace the bolts > Replace the nuts and tighten Working position Transport position Positioning the lateral stone guards for work The stone guards are secured in transport position for shipment; to position the two stone guards in the correct working position, proceed as follows: > Remove the locking pin from the pivot pin (7) > Remove the pivot pin (7) from the transport position hole > Raise the stone guard > Insert the pivot pin (7) in the working position hole > Reinsert the locking pin in the pivot pin Working position Transport position 7 7 12

Hitching the machine Hitching the machine We strongly recommend that you observe the safety warnings given in the previous pages of this manual. The category of the tractor 3-point linkage must match that of the implement. Mounting bracket for Cat.2 linkage Mounting bracket for Cat.2+3 linkage To attach the harrow to the tractor, proceed as follows: > Line up the tractor with the harrow > Insert the lower links of the tractor's hydraulic linkage in the corresponding mounting brackets on the implement, which should both be positioned at the same distance from the tractor. > Secure the lower links with the pins and locking pins provided. NOTE Attachment is made easier if the lower link stabilisers are adjusted so as to allow the lower links to move freely. On completion of the hitching operation, the stabilisers should be adjusted so as to limit oscillation (during implement transport, all oscillation must be completely eliminated). > Insert the end of the top link of the tractor's hydraulic linkage in the upper mounting bracket of the harrow and secure it with the relative pins and locking pins. > Adjust the length of the top link, bearing in mind that the drive shaft transmitting power from the tractor Pto to the harrow must be horizontal when the implement is in operation. NGH NGS 13

Hitching the machine NOTE In working position, the top link of the tractor's hydraulic linkage should slope down towards the tractor (see next figure). This configuration enables the implement to overcome obstacles and ensure that the roller is loaded correctly. Incorrect adjustment (e.g. top and lower links parallel) will result in an excessive load on the implement and the roller. Tractor and implement combination: do not exceed the maximum permitted weights! The combination of the mounted implement and tractor must not exceed the maximum permitted weight, i.e. the maximum permitted axle loads and the load capacity of the tractor wheels. At least 20% of the tractor weight must be supported on the front axle of the tractor. Connection of the drive shaft Check the dimensions! Before connecting the drive shaft, check that its dimensions are suitable for attachment to the tractor's Pto. If the drive shaft is too long, this could cause serious damage to the transmissions of the tractor and the harrow, as well as to the shaft itself. If the drive shaft is too short, the two halves of the shaft could become separated with a consequent risk of serious injury and damage. To check the length of the drive shaft, proceed as follows: Place the two halves of the drive shaft assembly (the half connected to the tractor Pto and the half connected to the implement) side by side; the tractor Pto half and the implement half should be parallel; the angle can be adjusted by way of the top link of the hydraulic linkage. If the sliding distance of the shafts is less than 40mm, then both the halves will have to be shortened by a corresponding amount. Maintain the difference in length between the outer tube and the inner section. Always make sure that the maximum coverage of the sliding element is maintained. The coverage should be at least 1/3 during operation. With the harrow in the working position, the angle of the drive shaft should not exceed 20 (for example, at a working depth of 10 cm), while the maximum permitted angle is 25. A B C D E F 14

Hitching the machine Connection of the drive shaft to the harrow 9 10 11 8 Proceed as follows: > Clean and grease the input shaft of the implement and the internal splines (9) of the universal joint. > Unscrew and remove the screws (10) securing the splined coupling of the drive shaft to the implement input shaft. > Loosen the screws (8) securing the shield (11) to the flange on the implement. > Detach the shield by turning it clockwise and slide it along the driveshaft. > Slide the universal joint (9) along the implement connection half of the drive shaft until the holes for the bolts in the joint are positioned in correspondence with the splines on the shaft. > Insert the screws (10) in their holes while moving the joint slightly, then tighten the screws (torque setting 70Nm) > Make sure that the universal joint is securely fixed > Slide the shield (11) back along the drive shaft to its original position and attach it by turning it anticlockwise. > fix the shield in position with the screws (8). > Check the two half shields rotate freely and independently of each other, then attach the support chain for the shield tube. During work, check at regular intervals that the universal joint screws are correctly tightened. Connection of the driveshaft to the tractor Proceed as follows: > Clean and grease the Pto output shaft and the internal splines of the universal joint. > Fit the tractor connection half of the drive shaft on the tractor Pto output shaft. > Release the universal joint safety locking device > Fit the drive shaft half on to the Pto stub shaft > Secure the drive shaft with safety lock > Check that the drive shaft is securely fixed 15

Preparation for work Preparation for work Checking the oil levels We strongly recommend that you observe the safety warnings given in the previous pages of this manual. Risk of burns! Beware of hot surfaces and hot oil. Before proceeding, check: the transmission grease level the gearbox oil level that all the components that require greasing have been greased (see maintenance section) Transmission grease level > Position the machine so that it is level. > Unscrew the grease filler cap located on the frame. > To check the level, use a graduated dipstick and follow the indications in the figure below; if necessary, top up with EP NLGI 00 G00K DIN51826 gear lithium grease. > Replace and screw on the filler cap. Do not exceed the prescribed levels NGH NGS GREASE LEVEL MAX 16mm GREASE LEVEL MAX 24mm GREASE LEVEL MIN 9mm GREASE LEVEL MIN 18mm 16

Preparation for work Gearbox oil level The procedure for checking the gearbox oil level varies according to whether the gearbox is of the exchange speed or lever change type; Do not exceed the prescribed levels NOTE (NGS 301-401-451) The lubricant used in the gearbox (NGS 301-401-451) is synthetic lubricant: do not use other types of oil [original oil (PAG) ISO VG 320 DIN 51502 PGLP] 12 Exchange speed gearbox > Position the machine so that it is level. > Unscrew the dipstick screw (12) (see figure) > Check the oil level: the oil level should be up to the mark on the dipstick > If necessary, top up with gear oil using a funnel: Mineral EP ISO VG 460 DIN 51517 TEIL 3 CLP --> NGH Synthetic (PAG) ISO VG 320 DIN 51502 PGLP --> NGS > Replace and tighten the dipstick screw 13 14 Lever change gearbox > Position the machine so that it is level. > Remove the oil level plug (13): the oil level should lap up against the lower edge of the hole. > If necessary, top up with gear oil using a funnel: Synthetic (PAG) ISO VG 320 DIN 51502 PGLP --> NGS > unscrew filler screw (14), top up the oil level, replace and tighten the screw. > Replace and tighten the level plug (13). Working speed The following table indicates the standard gearbox speeds as set in the factory. In normal conditions, these speeds will provide optimum working results. We generally recommend using a Pto speed of 1000 rpm, as using less torque will lead to a longer working life for the drive shaft.

Warning! Risk of burns > Pull the detent (16) upwards to release the lever (17), then move the lever to correct position for the required speed. > Insert the detent correctly. 19

Transporting the implement on the road Transporting the implement on the road Observe the safety rules! Particularly those regarding lifting (see Page 8.) Do not exceed the transport width of 3.00 m when transporting the implement on public roads. If necessary, transport the implement transversely on a suitable trailer. If it is necessary to load the implement on a truck, check that all parts are positioned and secured in such a way as to avoid damage and hazards. Positioning the stone guards When transporting the implement on the road, insert the pin (18) to limit movement of the stone guards, see figure below. 18 20

Preparations in the field Preparations in the field Lateral stone guards The stone guards must be set to the working position: to do this, make sure that the pin (18) that limits movement of the guards is inserted in the correct hole and secured with the cotter pin. Adjust the side plates as follows: > Remove the screws (19) securing the side plates (20) and position the plates at the correct height from the ground according to the required working depth of the harrow. > Insert the screws and retighten. 18 20 19 > The stone guards should be adjusted in accordance with the position of the roller, as shown in the figure below. Adjusting the working depth To set "medium" working depth on the depth adjustment plates (21) located on the right and left sides of the harrow: > Remove the lock pins (22) from the square pins (23). > Pull out the square pins (23) and reposition them in the "third hole" of the centre row of the depth adjustment plates (21). > Secure the square pins with their lock pins (22). This adjustment can be changed in the field if required. 21

Preparations in the field 22 21 3 rd Hole 23 Adjustment of the levelling bar The rear levelling bar serves to level the soil and to contain clods within the working area. It should be adjusted in accordance with the position of the roller (see figure below). To adjust the levelling bar, refer to the figure below and proceed as follows: > Remove the locking pins (24) from both adjustment handles (25) and turn the handles (25) to adjust the height of the bar (26) so that it is positioned at a height above ground equal to the working depth +2 cm. > Fix the levelling bar in position by locking the adjustment handles with the locking pins (24). 25 24 26 Warning: Raise or remove the levelling bar when the soil conditions are such that it forms mounds of compacted earth (very wet ground). NOTE Incorrect positioning of the bar will prevent it from functioning properly and in extreme cases may even cause it to break. 22

Preparations in the field Positioning the track eradicator The track eradicators (27) are mounted on two support bars (28). In the case of the NGH models, these support bars (28) are bolted to the frame, while on NGS they form part of the frame itself. The individual track eradicators must be positioned in the centre of the tracks left by the tractor tyres and adjusted to a working depth of approximately 5 cm. The track eradicators must be positioned at the sides of the track, at the same working depth. NGH 27 28 NGS 27 28 23

Cleaning, care and storage Cleaning, care and storage Safe storage Store the machine in a dedicated storage area away from vehicles, people or animals in transit! Do not allow children to come near or to play on the stored machine! Park the machine so that it is stable! Observe all applicable safety rules when unhitching the machine from the tractor Winter storage To ensure that the machine is in perfect working order at the start of the next season: clean the machine apply grease where indicated check the condition of the machine check that all bolt, nuts and screws are fully tightened replace any worn components replace any damaged components check the oil levels carry out all the necessary maintenance work spray the machine with an anticorrosion product NOTE Do not use a power washer in the vicinity of the breather plugs on the machine covers or on the gearbox or any other parts of the machine where water penetration could cause damage. 24

Maintenance Maintenance Before proceeding with any maintenance work on the machine, it is essential to carry out the following operations: never carry out any work on the machine while it is in operation the tractor Pto must be disengaged, the engine switched off and the key removed from the starter switch the machine and the tractor must be secured in a stable position; the tractor's hydraulic linkage control must be locked to prevent it being lowered accidentally. After the first two (2) hours of operation, check the tightness of the bolts and screws; also check their tightness each day before starting work. We recommend that you use only original replacement parts. Each day, before starting work, check the oil levels in the gearbox and the grease in the transmission casing. Lubricate with multipurpose grease the levelling bar height adjuster (every 50 hours), and the bearings of the rollers (every 10 hours).

Maintenance Replacing the tines of the harrow We strongly recommend that you observe the safety warnings given in the previous pages of this manual. Before proceeding, check that: the tractor Pto is disengaged, the engine is switched off and the key has been removed from the starter switch that the tractor wheels are chocked that the hydraulic linkage control has been locked to prevent the linkage being lowered accidentally. We recommend that you use only Kverneland original replacement parts. NOTE The tines may continue to be used until they are worn down to half their original length, at which point they should be replaced. Tines worn down to 150 mm in length (half the original length) may only be used at very shallow working depths. To replace the tines, raise the machine and use suitable equipment to prevent it from falling; to remove the old tines, follow the indications given in the figure below. To fit the new tines, carry out the steps illustrated in reverse order. 28
