    Instructions and settings Horizontal alignment Figure 3.16 The pitch of the drill is adjusted in the field using the push rod (A). The outer side plates must be completely parallel to the ground when the drill is sowing at the correct depth. Check the horizo- ntal alignment by ensuring that the forward seed coulters sow at the same depth as those at the rear.

  • Page 69: Advice On Sowing

    RD 300-450 F Advice on sowing Sowing depth Figure 4.1 See ”3.6 Adjusting sowing depth” on page 33. The most important task for the Rapid operator is to carefully and continually check the sowing depth. The sowing depth is set using the depth stop on the lifting ram. The numbers on the scale do not represent absolute values of sowing depth in centimetres.

  • Page 70: Checking The Seed Feed

    Advice on sowing Checking the seed feed Figure 4.2 The seed feed should be checked at the same time as the sowing depth, i.e. after every 4 hectares or once an hour. When checking the seed feed, you must ensure that the drill appear to be delivering the same quantity from each coulter.

  • Page 71: Sowing Headlands

    RD 300-450 F Sowing headlands Figure 4.3 In dry and fine conditions, the headlands should be sown first. In wet conditions or on soils susceptible to compaction, higher yields can be obtained if the headlands are sown last. The headlands can be marked out by finishing off the last tillage operation before sowing (e.g. au- tumn harrowing) by harrowing the headlands last.

  • Page 72: Tramlining

    Advice on sowing Tramlining The tramline options possible and the settings on the Control Box are described in ”3.16.3 Pro- gramming the Type III Control Box” on page 54 and ”3.16.8 Tramline options” on page 62. During sowing, the most important thing to remember about tramlining is to shut off Autostep before doing anything other than normal sowing or turning in headlands between bouts.

  • Page 73: Autumn Sowing

    RD 300-450 F Autumn sowing All tillage operations must be able to deal with soil compaction, trash and weeds. Before sowing, these factors must be considered and dealt with. If the soil is very compacted, it must be loosened, and if there is a lot of chopped straw present it must be incorporated. This can be done either by conventional ploughing or by ploughless cultivation, using the right equipment and techniques.

  • Page 74: Spring Sowing

    Advice on sowing 4.13 Spring sowing To ensure good emergence after spring tillage, the following points should be observed: ! Level the soil in the autumn until the surface variation is 10 cm or less. ! Sow early, this requires good capacity and technology ! Ensure a uniform sowing depth ! Avoid incorporating dry soil into the germination zone ! Re-compact very loose soil...

  • Page 75: Cultivating Silty Soils

    RD 300-450 F 4.16 Cultivating silty soils 4.16.1 Spring sowing on silty soils Silty soils are very slow to dry out and warm up in the spring. This is mainly due to the excellent capacity of these soils for capillary transport of water to the surface. Autumn ploughed silty soils have time to consolidate during the winter and this produces the continuity of pores which creates good capillarity and resultant slow surface drying in the spring.

    Maintenance and service Maintenance and service Figure 5.1 Figure 5.2 Figure 5.3 NOTE! During all work under the drill or where there is a danger of crushing, the drill must be completely and securely supported. Secure the drill on trestles or stands and lock all lifting rams with their yellow locking devices.

  • Page 77: Seed Feed Housing And Rape Brush

    RD 300-450 F Seed feed housing and rape brush Figure 5.5 Figure 5.6 The inside of the seed feed housing must be cleaned out regularly and frequent checks must be made for signs of wear on plastic and rubber components. It is specially important to ensure that seed additive deposits do not build up in the scoops, reducing their volume.

  • Page 80: Storing The Drill

    Maintenance and service Storing the drill Figure 5.16 The drill should be stored indoors when not in use. This is particularly important because the drill contains electronic equipment. The electronic components are of very high quality and can withstand a lot of moisture but we still recommend that the drill be stored indoors. The Control Box should be stored at room temperature during the winter and between seasons.

  • Page 81: Changing Discs

    RD 300-450 F 5.11 Changing discs Make sure that the drill is securely supported on trestles. When changing discs, use a ratchet spanner or preferably a nut runner. Turn the disc so that the completely flat side faces the seed coulter. NOTE! The discs have sharp edges, so wear gloves! Adjust the coulter if necessary, see ”3.22 Adjusting the seed coulters”...

    Maintenance and service 5.16 Changing the valve seals on the lifting ram Figure 5.24 NOTE! When servicing the hydraulic system, the side sections and the seed drill should be lowe- red, with zero pressure in the respective hydraulic circuit Remove hose (F), with care if there is any pressure left in the system. Remove the seat (E), the guide (C) and the piston (A).

    RD 300-450 F 5.17 Repairing and replacing seed hoses Figure 5.25 Repair If a seed hose is worn or bent, it can be patched with a joint, Part No. 415397 for Ø32 mm hose. This dimension refers to the internal diameter of the hose and the external diameter of the joint. Cut the hose in the centre of the damaged area.

    Maintenance and service 5.18 PTO driven hydraulic fan, mftg. no. -10 949 The fan design includes a built-in oil system filled with special oil and fitted with an oil filter. The system capacity is about 10 litres of oil. Use SHS 46 quality oil. Be careful during maintenance to prevent impurities entering the oil.
  • Page 87 RD 300-450 F 5.18.3 Draining condensed water: Before the fan is used at the beginning of a new season and when the fan has not been used for a long time, condensed water should be drained from the tank. ! Place the equipment to allow the tank to rest at an angle towards the drain at the bottom. ! Remove the drain hose (B) from the coupling at the bottom of the tank (hold the nipple in po- sition with a wrench when the hose is loosened), and drain water from the system.

    Maintenance and service 5.19 PTO driven hydraulic fan, mftg. no. 10 950- The fan has an inherent oil system with a special oil and a separate filter. The system has a capacity of approx. 40 liters of oil (SHS 46 quality). During maintenance work, always pay attention that the oil does not become contaminated.
  • Page 89 RD 300-450 F 5.19.3 Draining condensing water Prior to first use each season or following extended interruption, be sure to drain condensing water from the tank. ! Park the machine on an inclination to have the tank inclined towards the drain connector at its bottom.

    Troubleshooting Troubleshooting General information on troubleshooting Many of the functions of the drill are controlled by a series of electrical, hydraulic and mechanical components. A good way to exclude many of the sources of faults from the start is to first deter- mine whether the fault is electrical.

Sowing depth varies from centre to wings! (RD 400-450 F)! - Check that the long piston rod of the folding ram is fully out and does not creep in during work.
  • Page 96 Troubleshooting Leakage from the shaft seal on the fan's hydraulic motor! - Leakage from the shaft seal of the hydraulic motor may be caused by: - Damage caused during fitting. - Wear due to dirt. - Wear due to too high pressue in the drain line. - A damaged seal caused by very high pressure in the drain line.

    RD 300-450 F Notes on troubleshooting Hydraulic solenoid valves Figure 6.1 Figure 6.2 A solenoid has a coil which acts as an electromagnet when a current is passed through the sole- noid. It is easy to see if current is getting to the solenoid since the connector diode light comes on and the coil becomes warm after a few minutes.

Easily tested since a diode on the back edge of the sensor lights up every time it registers an object. Capacitive sensor Figure 6.5 Responds to objects containing moisture - seed, a hand, etc. Easily tested since a diode on the rear edge of the sensor lights up every time it registers an object.
