INTRODUCTION
Väderstad Rapid A 500-800 S is a high-capacity cultivation drill. The Rapid drills can be
used under a large variety of conditions, from "direct drilling" to sowing straight after the
plough. This versatility is made possible by the drill's coulter system design and its unique
depth control system, amongst other features.
The machine can be fitted with different types of pre-implements to suit varying farmland
conditions.
IMPORTANT!
This instruction manual is based on experience and results obtained during development of
the Rapid series of drills. Hints and guidelines are to be regarded as general advice, entail-
ing no responsibility whatsoever on the part of Väderstad-Verken AB and/or its represent-
ative. All responsibility for usage, road transport, maintenance and repair etc. of the drill
rests with the owner/driver.
Local conditions affecting crop sequence, soil type, climate etc. may require procedures
different to those mentioned in this manual.
The owner/driver is solely responsible for using the drill correctly in every respect.
Väderstad drills are subjected to thorough quality assurance inspection and function test-
ing before delivery. The user/purchaser shall retain sole liability for ensuring that the
equipment is functioning correctly when in use. Väderstad-Verken AB shall not be liable
for any claims for indirect or consequential damages relating to losses incurred in connec-
tion with the use of the drill. Väderstad-Verken AB accepts no liability for losses arising
from incorrect use of the drill, including its depth control and seed dosage equipment.

1 Safety re ulations
1.1 Before usin the drill
Figure 1.1
!Always pay extra attention to paragraphs or figures bearing the following symbol:
!Learn to handle the drill correctly and with care. The drill can be dangerous in inexperienced
or careless hands.
1.2 Warnin decals
Figure 1.2
A Read the instructions carefully and make sure you understand them
B Ensure that the entire operating and extension area of the drill is clear. Never walk under a sus-
pended section. Always check that the automatic catches have engaged before transport or
parking. To keep the automatic locks in perfect working order, ensure that the locking bars are
greased regularly.
C Warning tape. Danger of crush or impact injuries. Also used on safety features.
D Never work under the drill unless it is properly supported on trestles or stands on a firm surface.
Secure the lifting rams (x3) and the push rod ram (x1, Accessory) with the yellow locking de-
vices. See also ”3.24 Locking the lifting rams during service” on page 65.

E Drills with a PTO driven hydraulic pump: Pay attention to the rotating transmission for the
hydraulic pump. Do not stride across or stay close to the rotating parts. Disconnect the trans-
mission, switch off the ignition of the tractor and take out the key whenever work close to the
hydraulic pump or other maintenance work is required. Do not use the protective cone as a
stepping board.Make sure the protective cone is securely attached to the hydraulic pump. If the
protective cone is damaged, be sure to replace it immediately. Always secure the hydraulic
pump in the top rod mount on the tractor.
F Beware of injuries to your feet. When changing from working to transport mode, the machine
can drop when the valve is switched over. See ”3.5 Switching between transport and working
modes” on page 28.
G Always ensure that the working area of the bout markers is free. There is a risk of being hit by
an extending marker or of being crushed between the drill and a returning marker.
NOTE! The bout markers fold automatically when the drill is lifted, regardless of the setting
on the Control Box. Switch off the Control Box when the machine is not in the field. The Con-
trol Box stores all values when switched off.
If the machine is parked and left resting only on the wheels and support leg, the bout markers
could start to slowly unfold due to internal overleakage in the hydraulic system. Make it a habit
to always park the machine on its wheels, discs and support leg and always block the bout
markers with the safety cotter pins.
H Do not climb onto the wheels of the drill when it is parked, as they can rotate.
I Do not stand on the drill while it is in use. Do not stand on the grating of the seed hopper un-
necessarily as there is a danger of falling. NOTE! Where talc is used, e.g. when sowing peas,
the hopper grating can become extremely slippery.
J Do not stand on the drill during front-loading of seed
K NOTE! High transport height, especially RDA 800 S, see ”7.5 Technical data” on page 120,
transport height. Watch out for overhead cables, bridges, doorways, trees, Always check the
height restrictions of the transport route.
L Beware of high-pressure oil jets, the hydraulic system includes accumulators. Before starting
any maintenance or repair work on the hydraulic system, the accumulators must be drained of
oil. See ”5.15 Bleeding the hydraulic system accumulators” on page 84.
M Do not stand between the tractor and the machine when reversing the tractor to hitch the drill.

Safety re ulations
10 Ver.2 01.11.2002
1.3 Other safety precautions
!Observe the greatest caution when transporting the drill on a public road. When driving with a
full hopper, remember that the following weight is great and that the view to the rear is very
restricted. Check the position of the tractor rearview mirrors. If the machine is to be transported
over a longer distance, be sure to block the lifting ram of the centre section with the yellow
mechanical locking device.The owner/operator is solely responsible for transport of the seed
drill on public roads. Use the lights on the drill according to the local traffic regulations.
! NOTE! This machine and its tyres are designed for a maximum speed of 30 km/h on the road.
!During service or repair work on the hydraulic system, the wing sections must be lowered and
the drill must be in the lowered position and resting on a firm surface.
!Never stand under the intermediate packer or drill if it is suspended and only secured with the
tractor's hydraulic lifting arms. Prior to any service on the intermediate packer, be sure to se-
cure it properly with trestles, etc. on firm, level ground.
!Before service or repair work on the weight transfer hydraulic system, the accumulators must
be drained of oil. See ”5.15 Bleeding the hydraulic system accumulators” on page 84.
!Be sure to set the master cylinder stopper in such a way that the drill rests on both the wheels
and the discs when parked. Since the pressure on the supporting leg is great, the machine shall
not be parked on loose surfaces.
!Always ensure that the male coupling of the drill and the female coupling on the tractor are
clean before connecting.
!Always use Väderstad original spare parts to maintain the quality and reliability of the seed
drill. If other makes of spare parts are used, all guarantee and claims commitments cease to be
valid.
!Regularly inspect the wear on the drill's towing eyelet. Replace the towing eyelet when it has
been worn down to the wear limit. See ”3.2 Inspecting the drill's towing eyelet” on page 24.
!Any welding work on the machine/implement should hold professional standard.
Incorrect welding may result in serious injuries or possibly fatal injuries. If in doubt, contact a
professional welding service for proper instructions.
!Never look straight into the optics of the radar when it is operating! There is a risk of permanent
damage to the eyesight! (Hydraulic feed output).

2.12 Installation of the Control Station on the tractor
Figure 2.13
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! Check for hidden cables before drilling holes in the tractor cab.
Connect the cables: Brown to positive (+) and blue to earth (-).
NOTE! The polarity must not be reversed. If the tractor has an electric socket in the cab, use this.
If there is no socket, connection must be made using an extra cable, preferably 6 mm
2
. Do not use
a cigarette lighter socket as the current requirement may be as high as 20 A. It is important to
make a secure connection since poor contact will cause malfunction.
Make sure that the connecting cable to the drill is not trapped under the rear window of the tractor
as this may cause damage. Use a hatch or a hole. Clamp the cable securely onto the tractor to pro-
tect the Control Box from damage if the driver forgets to unscrew the connecting cable when un-
hitching the drill.
NOTE! Keep the Control Station switched off until the bout markers have been installed.
Now it is time to unfold the drill. Check that the Control Station is switched off.
NOTE! The following harrow and bout markers etc may be secured to the wheels or the platform
during transport and must be released before unfolding.
Before unfolding, see ”3.5 Switching between transport and working modes” on page 28.
Unfolding must always be performed with the drill fully raised.Release the locking devices
before unfolding.

2.13 Fittin the bout markers
Figure 2.14
Fit the bout marker arm (A) in the wing bracket (B).
Fold in the bout marker arm and check that the catch of the arm (C) fits against the roller (D) on
the wing. If necessary, adjust the bout marker arm height with the stop screw (E).
Fold out the bout marker a little. Switch on the Control Station and press one or more times
until the read bout marker indicator lights. Lower the machine using the hydraulics in order that
the ram extends a bit. Test fit the piston rod on the bout marker. Verify that the bout marker arm
passes across the roller, but is not under tension when folded in. Also verify that the bout marker
arm is not affected by the post-harrow linkage when it is raised or lowered. If necessary, adjust
the ram length by screwing the piston rod (F) using a key handle/nuts.
Lock the linkage head using a locking nut.
Fit the other bout marker in a similar fashion.
Verify the position on the bout marker pin (G). The distance (H) from the machine centre to the
tip of the bout marker pin must be 5.0 m on the RDA 500 S, 6.0 m on the RDA 600 S and 8.0 m
on the RDA 800 S. If necessary, adjust by first undoing the clamp (I) and then moving the outer
pipe. Make sure that the clamp and the bout marker pin are securely tightened.
NOTE! Be careful not to get pinched when operating the bout marker! Always make sure there is
nobody in the work area of the bout marker!

2.15 Fittin the scrapers
Figure 2.16
For transport reasons, some models may be delivered with the scrapers folded up. In such cases,
half of the fixing screws for the arm (B) are packed inside the hopper.
The distance between the scraper blade and the tyre should be at least 5 mm.
To check this: Let the drill rest on the discs, with the wheels a few centimetres over the ground.
Rotate the wheels and check that the scraper blades at no point come within 5 mm of the tyres.
NOTE! If the scraper blade is not in the right lateral position after fitting, the fittings can be adjust-
ed with a suitable tool.
Make sure the fixing screws for the scraper mounting are properly tightened
