  • Page 5 RDA 600-800 S INTRODUCTION Väderstad Rapid A 600-800 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 two large-dimension 3/8" hoses with plastic rings are used to raising and lowering the seed drill and to operate the markers. The two thin 1/4" hoses marked with plastic rings are used to fold down the side wings and adjust the front implements.
  • Page 14 Instructions and settings 2.4.3 Connecting hoses to the hydraulic fan Figure 2.7 Figure 2.8 Connect the two thin hoses to a two-way hydraulic connector designed for continuous operation of a hydraulic motor. If available, use a priority connector. The thicker hose of these two hoses is the pressure hose to the hydraulic motor, while the thinner is the oil leakage hose.

  • Page 67: Sowing Headlands

    RDA 600-800 S Figure 3.3 Check regularly whether the seed level is sinking evenly in both windows. Get into the routine of quickly looking over the drive shafts, gears and chains to see that every- thing looks normal and is still in place. Regularly ensure that the seed box rollers rotate at uniform speed.

  • Page 68: Engaging The Drill

    Advice on sowing Engaging the drill Figure 3.5 The drill must always be moving when lowered to ground. Keep the hydraulic lever in the pres- surised piston, i.e., lowering position, until the bout marker has been completely folded out. Using the Control Station, verify that tramlining has been advanced and that the correct lamp goes out and the correct one lights and that the alternate during subsequent raising.

  • Page 90 Troubleshooting Unintentional very slow unfold- ing of retracted bout marker(s)! - Check that the indicator lamp of the bout marker is not lit on the Control Station. - Check that the electric valve (A) or (B) of the bout marker does not receive current. See ”5.1.3 Hydraulic electric valves”...
  • Page 91 RDA 600-800 S The drill cannot be raised and/or lowered! - Check whether the lift stop or low-lift mode has been set. - See ”5.1.2 Hydraulic fault” on page 86. If the drill cannot be raised: - Check whether the lift stop or low-lift mode has been set.
  • Page 92 Troubleshooting Leakage from the shaft seal on - Leakage from the shaft seal of the hydraulic motor the fan's hydraulic motor! may be caused by: - Damage caused during assembly. - Wear due to dirt. - Wear due to too high pressure in the drain line. - A damaged seal caused by very high pressure in the drain line.
  • Page 93 RDA 600-800 S The Control Station generates a seed box drive alarm! - Check whether the drive wheel has been lowered and In case of doubtful drive: drives against the ground. - Check the transmission between the drive wheel and the seed boxes.
  • Page 94 Troubleshooting The drilling depth of the centre and side section differs! - Check whether the long ram rod of the folding ram is completely extended and that the rod does not slowly retract during driving. - Check the weight transfer setting. See ”2.10 Adjusting weight transfer”...

    RDA 600-800 S Alarm list 2 Low seed level, right-hand side. - Check the seed level of the seed hopper. If there is seed in the seed hopper: - The sensitivity of the sensor has been incorrectly set. 3 Low seed level, left-hand side. - See alarm no.
  • Page 96 Troubleshooting 18 Seed fan, low rpm. - Check that the hydraulic hoses have been correctly connected to the tractor. - Check whether the hydraulic oil flow from the tractor has been correctly set. - Check the alarm time limits that were programmed into the Control Station.
  • Page 97 RDA 600-800 S 26 Seed box clutch, left-hand side. - This alarm is generated when seed shut-off on the left side does not operate. For other details, see alarm no. 28 Workstation not connected. - Check whether the intermediate cable between the Control Station and Workstation is connected.
