INTRODUCTION The Väderstad Carrier Drill 300 is a versatile, three point hitched implement designed for intensive cultivation, drilling and soil consolidation. Two rows of curved discs cut through straw and crop remains and mix straw and soil while creating an even surface. The implement works the soil efficiently at depths of 2 - 10 cm. To achieve the best result, drive at a steady speed of 12 - 14 km/h. The Carrier Drill 300 is not only an efficient primary cultivation implement. It also serves other useful purposes, such as levelling, preparation and consolidation of ploughed soil, normal rolling and fine seedbed preparation, making the implement a versatile tool on any farm. Carrier Drill 300 is primarily intended for drilling in unploughed soil. If the machine will be used for drilling in ploughed fields or very lose soil, it is recommended to first consolidate the soil in a suitable manner. This will achieve a uniform drilling depth across the full machine width. The Carrier Drill 300 with rubber compactor can be fitted with a draw-bar, which is mounted between the tractor's lifting arms and the three-point hitch on the implement. With this option in place, the implement travels partially lifted, while it rolls on the rubber compactor during transport. The draw-bar can be fitted with a Crossboard axle to improve performance on ploughed or previously cultivated soils.

Other safety precautions
Figure 1.4
! Because the implement is heavy, for most applications front-mounted weights should be installed on the tractor. To assure safe road transport, always make sure the tractor has sufficient weight on the front axle. ! Check whether the tractor tyres and wheels are designed for the weight of the implement and ensure the tyres are inflated to the correct pressure. Please note that the load on the rear axle of the tractor is high, especially during road transport. With this in mind, be sure the maximum load per axle is not exceeded. ! Make sure nobody is under the implement when it is suspended only by the tractor's three-point hitch! Prior to service and maintenance, unhitch the implement from the tractor and arrange suitable supports as explained in the section ”5.1 Securing the implement prior to service” on page 56. ! Pay attention to the width and the extended turning area of the implement during road transport. To minimise the transport width, pull up the drive wheel to the transport position. Raise the ladder towards the platform. Obey local traffic regulations. The operator of the tractor carries sole responsibility for safe driving of the tractor and any hitched implements.
Figure 1.5
! Keep in mind that the implement is heavy and as a result the braking distance is longer. ! Use the lights on the implement in accordance with local traffic regulations. ! Prior to transport on public roads, remove dirt that may fall off from both the vehicle and the implements. ! Never stay close to a pressurised hose. Be sure to recover any spilt oil when working on the hydraulic system. ! Prior to connecting the hydraulic hoses, be sure that the male couplings of the implement and the female couplings of the tractor are clean and free of dirt. ! Before using the machine, check that all nuts and bolts are tight. ! Always park the implement on a level and solid surface. Depressurise the hydraulic system of the implement by using the floating position of the tractor's hydraulic levers. This enables the implement to rest on the discs and the roller. ! To maintain the high level of quality and operational safety of the implement, use only Väderstad genuine spare parts. The warranty and any claim commitments will become void if any other parts than genuine Väderstad parts are used.

Installing the Control Station-Bio in the tractor
Figure 2.1
Be sure to install the control box securely in the tractor cab. Place the control box within the field of vision while looking in the travelling direction. Install the bracket as shown in the figure. NOTE!Prior to any drilling in the tractor cab, be sure to check possible concealed wiring.
Connect the cables as follows: brown to plus (+) and blue to earth (-). NOTE!Do not mix up the poles! If the tractor is fitted with a power outlet in the cab, use this outlet.
If a power outlet is not available, an extra cable must be prepared. Preferably use a 6 mm² cable dimension. Do not use cigarette lighter outlets, since the current requirement can reach 8 A. It is important that the connection is correctly made, because any looseness could make the function unsafe. Make sure the connection cable to the drill is not pinched under the rear window of the tractor, since this could easily damage the cable. Use the designated connector port or cable hole. Use staples to securely fix the cable in the tractor cab. This protects the control box from damage in case the connection cable has not been disconnected prior to unhitching the drill.

Tractor
Figure 3.1
To reduce compaction of the soil and to increase the pull, the tractor should be fitted with very good tyres. ! Check whether the tractor tyres and wheels are designed for the weight of the implement and ensure the tyres are inflated to the correct pressure. Please note that the load on the rear axle of the tractor is high, especially during road transport. With this in mind, be sure the maximum load per axle is not exceeded. ! Because the implement is heavy, for most applications front-mounted weights should be installed on the tractor. To assure safe road transport, always make sure the tractor has sufficient weight on the front axle! The basic machine without bout markers requires double-acting hydraulic connectors. The machine fitted with bout markers requires two double-acting hydraulic connectors.

Hitching and unhitching the implement
Figure 3.2
3.2.1
Hitching to the tractor
1 Adjust the tractor lifting arms to the same height. 2 Reverse the tractor until it is about one metre from the hitching points on the drill. Apply the tractor's parking brake. 3 Connect the hydraulic hoses from the bout markers to a double-acting hydraulic connector (option). 4 Fold out one of the bout markers (option) for better access between the drill and the tractor's rear wheel when hitching the implement. 5 Reverse up to the hitching point and apply the parking brake of the tractor. NOTE!When reversing the tractor, make sure there is no one between the tractor and drill! 6 Connect the drill to the three-point connector on the tractor. 7 Connect the hydraulic hoses for the depth setting of the machine. 3.2.2
Unhitching
1 Lower the implement onto level, solid ground. 2 Depressurise the hydraulic system of the implement by using the floating position of the tractor's hydraulic levers. This enables the implement to rest on the discs and the roller. 3 Disconnect the hydraulic hoses and the three-point couplings. Secure hoses and cables in the special holder on the front of the drill.

Instructions and adjustments 3.2.3
Selecting the hitching points A B A
Figure 3.4
The implement has been designed for three-point hitching, category II or III. ! To minimise the required lifting power, the top rod should be mounted at a high hitching point on the tractor and in a low hitching point on the implement. ! To get sufficient lifting height for implements equipped with following harrow the top rod should be mounted at a low hitching point on the tractor and in a high hitching point on the implement. The round holes (A) are used if the length of the top rod will be used to adjust the height of the front part of the implement. When using these hitching points, the tractor's hydraulic arms should be in the floating position when driving in the field. The oblong hole (B) is used if the height of the front part of the implement will be adjusted using the hydraulic arm height setting. Adjust the length of the top rod until the cotter pin is in the middle of the oblong hole when the implement is parallel with the ground. Then fine adjust using the hydraulic arm height adjustment when driving in the field. The oblong hole (B) is not recommended for drilling. 3.2.4
Stabiliser rods on the tractor's hydraulic arms
! When driving in the field and for road transport, the stabiliser rods on the tractor's hydraulic arms should be blocked. Also make sure the hydraulic arms are centred.

Figure 3.6
The discs' working depth and the drilling depth is determined by the roller setting. The roller is adjusted using the hydraulic ram (A). The piston rod can be fitted with clips (B) to permanently lock the end position of the ram. The more clips installed on the rod, the more shallow the working depth. Clips not used should be stored in the holder on top of the frame. ! Fold up the lower part of the platform to gain access to the cylinder and clips. ! Please note that ground parallelism of the implement is affected by a change in the working depth.

Ground parallelism setting
Figure 3.7
The height position of the front part of the implement can be adjusted by altering the length of the top rod or adjusting the height of the hydraulically operated arms, depending on which hitching point has been selected in the implement's hitching tower. See ”3.2.3 Selecting the hitching points” on page 20. Adjustment is performed while driving in the field, at which time it should be checked which height setting results in straight pulling of the implement behind the tractor. Please note that the height position of the front part of the implement must be readjusted if the roller position is changed. This will prevent uneven pulling of the implement and a varying working depth.
3.5
Height adjustment of outer discs, mftg. no. -197 A
Figure 3.8
To prevent the implement from leaving trailing lea lines, the height of the outer disc on each side can be adjusted. Choose a setting that suits the work depth, soil type, etc. Undo the nuts and pull out the bolts (A). Select a track position. Insert the bolts again and lock them with the nuts. NOTE!This adjustment will affect the drilling depth. 22

The side plates of the implement prevents ridges from forming in the field. The side plates can be adjusted vertically to suit different operating conditions. Place the pin (A) in the hole corresponding to the desired height. NOTE!The side plates should operate just above the soil surface, so avoid setting them too deep.
Prior to road transport and to keep the transport width within 3.0 m, disassemble the side plates. Place the side plates in the special holders (B) on the scraper when transporting the machine on public roads. Secure the side places with the rubber strap. NOTE!The side plates should not be set in the transport holders when working in the field. If the
side plates will not be used, then leave them behind in the machinery hall or next to the field.

To optimise the work result, the front disc row can be laterally offset. Undo the axle brackets (A) and adjust the stretching screw (B). Lock the axle in position by tightening the brackets. Adapt the front disc row setting to ensure the discs work on the full width of the implement at the set working depth. Avoid performing this setting in soil not yet cultivated (C). Check the result after scraping off the soft dirt behind the discs. In the example above, the front disc row should be moved slightly to the right in order to optimise the result. Keep in mind that the end result depends on the work depth, the soil type and the travelling speed. ! Side-shifting of the front disc row affects the row spacing when drilling!

Scraper for compactor with steel rings
Adjust the scrapers until the tips of the same are as close to the roller rings as possible, but be sure they are not in contact. Scrapers for compactor with rubber rings
Adjust the scrapers until the tips are approx. 15 mm from the rubber rings. This is the standard setting. If the rubber compactor becomes too soiled, adjust the scrapers step by step closer to the compactor roller. ! Make absolutely sure the scraper blades do not make contact with the rubber compactor, since it can then be shredded to pieces. ! Regularly check to make sure stones do not become wedged between the rubber rings.

Adjustment
Adjust the bout markers as shown in “Figure 3.13”. This adjustment is approximate. To avoid double-seeding or non-seeding, which may occur if the operator sits at an angle in the tractor, a follow-up check should be done in the field. Depending on the type of tractor and the operator position, the bout mark may be observed differently. The bout marker should be adjusted after about an hour’s time of operation. Also verify that the tractor's hydraulic arms are locked in the centre position. 3.9.2
Operation
The markers are operated using a separate hydraulic circuit connected to a double-acting hydraulic connector on the tractor. The system has a hydraulic block with electric valves that control which marker to fold down. The hydraulic block is controlled by the machine's Control Station-Bio and a lifting switch placed next to the drive wheel of the machine. For adjustment of the system, see ”3.13.1 Functional description” on page 45. NOTE!During transport, maintenance and storage, always lock the bout markers using the locking
pins (A).

The CR Drill 300 features cell wheel/studded feed rollers. One Fine roller (F) has been paired with each Normal roller (N). The thinner Fine roller is used to sow small seeds, such as rape and turnip (see Seeding table). The Normal roller is used to sow other seeds in larger volumes. When sowing small-size seeds, the Normal roller should be released by pushing the plastic cotter pins (A) of the rollers to the left using a screwdriver. Before engaging or disengaging the Normal rollers, be sure to flip down the special protective covers (C) that prevent dirt from entering the output units. NOTE!The plastic covers (B) can be folded down to, among others, make cleaning easier. How-
ever, it is important that the covers are closed when the pins (A) are moved. If the covers remain open, the pins can be pushed out of their normal positions and cause damage to the seed boxes. ! During drilling, the plastic covers must always remain closed. It is also possible to drill only every other row.

Prior to commencing sowing, lower the drive wheel from the transport position to the operating position by pulling out and folding the wheel down. NOTE!The drill must be in the raised position when changing the drive wheel position. If the ma-
chine is lowered, there is a danger of being crushed since the wheel is spring loaded. Prior to transport and to reduce the width of the machine, return the drive wheel to the transport position. ! When drilling, make sure the drive wheel has contact with the ground and offers proper traction. The lifting wire (A) of the drive wheel should be free of tension. A

Make a cut on both sides of the bag and let the seed or fertiliser run out. Lift the bag before cutting open the bottom in order to more easily empty the remainder of the bag. Avoid contact with and inhalation of seed dressing. For calibration, the minimum filling depth is approx. 15 cm. Filling from small sacks
Figure 3.32
This is most easily accomplished by using a loader and putting the bags on a pallet. Lift up the pallet diagonally from the rear, in order that it is possible to safely walk up to the platform. Make sure nobody is present on the drill when the seed is brought up to it. Avoid contact with and inhalation of seed dressing. NOTE!Do not use the ladder on the drill to carry bags to the seed hopper.

Emptying the drill
If a small amount of seed or fertiliser remains in the hopper after completed work, this can be emptied by way of the calibration trays. Install the calibration trays, set the calibration flaps to the calibration position (position A) (see “Figure 3.24”) and completely open the bottom flaps. If a large amount of seed or fertiliser remains, the machine should be emptied on a clean and dry surface or a tarpaulin. It may be necessary to help force out inert fertiliser and large-size seed by cranking. Thorough cleaning of the hopper is most easily accomplished by using compressed air. Clean the machine carefully at the end of the season! Do not allow seed or fertiliser to remain in the drill for a long period of time!

Calibration of seed and fertiliser
Before calibration, check that the bottom flaps and sliding doors are correctly set and that there is sufficient seed in the hopper. The seed volume in the hopper should be at least 15 cm deep. Verify that tramlining is turned off.

6 Weigh the cranked out volume and compare with the desired volume. Collected volume x 100 = kg/ha. 7 If the volume is incorrect at the first attempt, adjust the setting and repeat the procedure. The transmission ratio of the gearbox is relatively linear, which implies that if it necessary to increase the seed/fertiliser amount by 10%, then the scale value should be increased by 10%. 8 Return the calibration trays to their brackets in the hopper, and return the calibration flaps to the drilling position B. The calibration procedure may be repeated after working a couple of hectares. Refer to the Notes under ”3.12.10 Test drive” on page 42. Alternative method. Check the consumption of the first seed/fertiliser portion in the seed hopper. Estimate the remaining volume and calculate the amount of seed that was sown in relation to the area that was covered. Regularly check:
! the drilling depth ! the seed consumption with respect to the covered area ! that none of the seed coulters are blocked by turning the drive wheel slightly

Instructions and adjustments 3.12.10 Test drive CRD 300
Figure 3.38
In order to check the actual output volume, a test drive can be made. 1 2 3 4
Install the calibration trays and set the calibration flaps to the calibration position (position A). Measure and drive a distance of 33.3 m. Weigh the output volume and multiply by 100. This is the seed consumption in kg/ha. Adjust the setting if required and repeat the test drive. Return the calibration flaps to the drilling position B and return the calibration trays to their brackets in the hopper. NOTE!Make a note of all the settings and the results in the enclosed table. See ”6.2 Calibration results” on page 67. Your own personal table is also a good resource to easily find the correct values. Note: The seed and fertiliser volume may vary, and usually increases after the first calibration has been made. According to trials made in Germany on an extensive line-up of grinding or studded feed roller systems, the drilled seed volume often increases as the work progresses since the seed tends to pack and the seed grains tend to align with each other. Such variations have been amplified by new types of pesticides and the use of a distributing shaft. This is why it is important to crank out a few kilograms of seed first before making the real test. It is also important that a certain volume of seed remains in the hopper. Since the seed in the box will stabilise after a short while of driving, another calibration can then be made when sowing has commenced.

The bottom flaps have been preset at the factory. In the bottom flap position 1, the play (A) between the feed roller and the bottom flaps should hardly be visible. The distance should be checked at the outer edge of the bottom flap. If necessary, use the adjustment screw (B) on each bottom flap to adjust the play. It is possible to adjust all flaps within the adjustment range of each separate flap by changing the level index (C). When the index has been changed, make sure that the bottom flap levers fit in the index positions. When weighing the calibrated quantity from the calibration trays, be sure to weigh the left and right tray quantity separately as this will indicate whether the same quantity is fed out on both sides.

Troubleshooting chart Control Station-Bio does not switch bout marker or advance!
The bout markers do not operate although Control Station-Bio shows switching operation!
The boat markers slide out when they are set to the parking position!
Tramlining does not work!
Area meter/speedometer does not operate or shows incorrect values!
The output amount is considerably reduced although the gearbox setting has not been changed.
20.06.2011 Ver.2
- Is the lifting switch operating? - Has the bout marker function selector been set to the alternating position? - Is the Control Station-Bio set to auto advancing?
- Does each electric valve receive power? - Are the cables and switches in good operating condition?
- Is the seal of the bout marker cylinder that slides damaged? - Is the electric valve leaking? If it is leaking, replace the valve. - Does the tramline coupling lock/unlock? Try manual cranking. - Is the tramline alarm sensor working? The sensor is built into the tramline coupling. - Can the tramline tube rotate on the shaft? Is the tube free of damage? - Are the cables and switches in good operating condition? - Has the correct tramline programme been selected?
- Has the correct number of pulses per 100 metres of travelled distance been programmed into Control StationBio? See ”3.13.3 Programming” on page 47. If too low a speed or too small an area is displayed, reduce the number of pulses. If too high a speed or too large an area is displayed, increase the number of pulses. Automatic calibration is recommended. - Has the distance between the sensor and the roll pin on the sprocket been correctly set? The adjustor is situated on the drive shaft sprocket on the left end plate of the machine. The distance should be approx. 1 -2 mm. The LED of the sensor should light when the pin passes. - Are the cables and switches in good operating condition?
- Check correct gearbox operation. Turn the drive wheel by hand. If the output shaft rotation is highly irregular, the cause could be a broken spring or another defect in the gearbox. The fault should be corrected by a service technician.
