    5 maCHine aDJuStmentS The seed drill should be adjusted on level ground before any seeding. For producing a good seeding result, it is important that the machine and its equipment are adjusted cor- rectly. Basic machine adjustments should be performed in the following order: Adjusting the hopper wall Aligning the packer (optional equipment) Adjusting the height of the machine frame...
  • Page 29 The wall is locked in place using three locking pins. Release the pin lock by lifting the pin upwards and turning it 90 degrees, after which the pin is released in its lower position. Lock in reverse order. If the cover is rolled open in the middle of the hopper, the cover rolling point can be adjusted according to the wall adjustment.

  • Page 31 A table indicating the number of lamellas placed onto the lifting cylinder at each see- ding depth is presented below. The precise number of lamellas depends on how much the machine wheels sink into the ground. When the machine is used for the first time, it should be pre-adjusted according to the table in advance, after which the frame height and coulter depth should be adjusted accurately in the field.
  • Page 32 puSHing arm in m-/D-SerieS maCHineS puSHing arm in S-SerieS maCHineS Before adjusting the pushing arm, a study maintenance support must be placed under the frame fastening lug in S- and M-series machines, on top of which the machine is lo- wered so that the pushing arm can be turned.

  • Page 39 5.10 Coulter SiDe plate in S- anD m-SerieS maCHineS The side plate located in coulters in Junkkari S- and M-series machines must be ad- justed correctly so that the coulter works properly. The side plate is suspended by three bolts, with spring washers pressing the side plate against the coulter disc.
  • Page 40 5.11 SeeDing DeptH anD preSS WHeel in D-SerieS maCHineS The control of the coulter seeding depth in Junkkari D-series machines is based on the height adjustment of the large depth control wheel located next to the coulter disc. The seeding depth is adjusted for each coulter by adjusting the height of the depth control wheel.
  • Page 41 Table below indicates coulter weights corresponding to spring pre-tightening lengths in the seeding position. The easiest way to determine the length of the pressurisation spring is to measure it from the front spring. The length is measured when the machine is raised up.
  • Page 42 Before any seeding, larger rocks and other significant obstacles must be collected so that they can be avoided. If obstacles are crossed carelessly, the coulters, wheels or other machine structures might be damaged. The correct working position of the coulter and frame secures a successful seeding re- sult and a sufficient coulter movement range when crossing obstacles.
  • Page 43 The lateral position of the trackmarker is adjusted by moving the spring fastener posi- tion along the marker pipe. The trackmarker position is measured from the middle of the drawbar or machine frame. Depending on the working width, the dimension must be 3,000 mm in 3-metre machines and 4,000 mm in 4-metre machines.

The working height of the harrow is adjusted by changing the po- sition of the nut on the threaded rod at the top of the harrow arm.
  • Page 45 Harrow tines have been divided so that they are located between seed rows. Harrow tines act on the centre line of the wheel and between the wheels. The purpose of the har- row is to loosen the topsoil rolled by the wheels so that rainwater can better penetrate the surface.

  • Page 49 Cleaning tHe FeeD roll 5.15.2 aDJuSting tHe Bottom Flap In the feed chamber, there is a curved bottom flap under the feed roll. Its tightness is controlled from the two levers located underneath the feeding mechanism. The lever adjustment affects the left and right bottom flaps. The bottom flap is spring-loaded and yields slightly if a foreign object or a fertiliser lump enters the feeding mechanism.
  • Page 50 SWitCH ValVe HanDleS anD poSitionS In position 1, any seeds or fertilisers left in the machine can be emptied into calibration trays. In this position, the bottom flap can be turned fully open so that small volumes of material can be drained easily into the calibration tray. If large volumes need to be emp- tied from the hopper through the metering device, seeds or fertilisers can be drained onto the ground through coulters when the switch valve is in position 3.
  • Page 51 5.15.4 CloSing HatCH There is a closing hatch between the feed chamber and hopper. If required, it can be used to close seed or fertiliser feeding separately from each metering device. When open, the closing hatch must always be fully open to ensure the even feeding of material.
  • Page 52 6 CaliBration anD DeFining tHe SeeDing Volume Calibration is a requirement for successful seeding. A seeding table is located at the end of the seed drill box which indicates example values for seeding volume adjustments. However, there are significant differences in seeds in terms of size, weight and flow, be- cause of which the actual seeding volume must be verified through calibration.
  • Page 53 Depending on the control unit, an electronic volume control for seeds and fertilisers is available for Junkkari seed drills as optional equipment. This allows the seeding volume to be adjusted while driving using the seed drill control unit. The calibration of a new machine should be repeated at least four times if the basic factory setting differs signi- ficantly from the calibration result.

  • Page 58 7 tramlineS As optional equipment, Junkkari seed drills can be equipped with tramline clutches controlled using the G-Wizard or ISOBUS control unit. Tramlines facilitate spraying and reduces the trampling effect. This results in more even growth. This section presents how tramlines are made and how the tramline width is fitted with the spray width. How the tramline and track width can be changed is presented at the end of this section.
  • Page 59 There are three ways to drive tramlines: Symmetrical Asymmetrical to the left Asymmetrical to the right Normally, the aim is to follow the symmetrical method. It is the simplest way and suitable for the most common seed drill-spray combinations. In a symmetrical tramline, the sp- rayer tramline is in the middle of the seeding line.
