Introduction to the Handbook This handbook provides the information for the operation, adjustment and maintenance of your Standen SP Series 3-Bed Potato Planter. To enable you to achieve the best results from the machine, the manufacturer recommends that you read the handbook thoroughly prior to using the machine for the first time.
The rear section of this handbook contains lists of spare parts available through your Standen Agents. Each illustration shows a complete unit or assembly in exploded form. Standen's policy of continual product development means that components or even complete assemblies are redesigned from time to time.
SAFETY PRECAUTIONS Safety The Standen SP Series Potato Planters have been designed to comply with current Safety Regulations. However, as with all machinery there will be inherent dangers whilst operating and carrying out maintenance on the machine. The following list of precautions should therefore be brought to the attention of all persons operating and working on the machine.

SAFETY PRECAUTIONS When left free standing i.e. not attached to the tractor, the machine must be on level ground. The operator must not leave the tractor seat until the machine has been lowered to the ground, the tractor engine switched off, the handbrake applied and the ignition key removed.
INSTALLATION Overview The SP Series 3-Bed Potato Planter is designed to be towed from the tractor pick-up hitch. The machine plants potatoes with extreme gentleness and accuracy. Seed spacing, planting depth and soil covering are all controlled for optimum results.
INSTALLATION Preparing the Planter for Transport Empty the hopper. Lower the top frame fully using the switch marked ‘FRONT LIFT RAISE/LOWER’. Raise the rear section of the tipping hopper. Raise the mould boards and secure them in the transport position with the pins (item 1, fig 2).
OPERATION Main Control Box Functions POWER ON/OFF: Power is ON when LED is illuminated. FRONT LIFT RAISE/LOWER: Raises/lowers front of machine to lift openers in and out of work. AUTO-DEPTH ON/OFF: Automatically raises/lowers individual pairs of openers to maintain planting depth in that bed. Auto-depth circuit is ON when LED is illuminated.
OPERATION Planting Careful planting is one of the pre-requisites for a good crop of high quality potatoes. The potatoes should be planted in straight ridges without gaps and at a correct and even depth. This is achieved when, at the beginning of planting, the functions of the planter and the different adjustments are carefully studied.
OPERATION Loosen the rear leg retaining screws (item 3, figure 4) and adjust the leg height so that that the panel runs parallel with the ground. The angle at which the pivot arms (item 4, figure 4) operate should be approximately 30° from horizontal allowing the panels to ride the contours of the ground.
OPERATION 1.10 The depth at which the centre plough operates is set using the top link (item 8, figure 5). The deeper the plough is set, the more soil it will push sideways. Care should be taken however as going too deep may move the seed in the bed. The mould boards are raised/lowered hydraulically from the control box.
1.11 OPERATION The feed belt motors are actuated by the sensors (item 1, figure 10) situated between the belts and the feeding pockets. When the quantity of potatoes in one of the feeding pockets is so small that the distance between the sensor and the potatoes is more than 8cm (or the feeding pocket is empty), the sensor gives the relay an impulse.
OPERATION 1.12 Insert Cups The shape of the feeding cups is designed to pick up the irregular long shaped seed in a large grade. For a seed grade with a wide range of sizes and long seed, every alternate cup should be fitted with a medium insert. For a narrow range seed grade with more irregular shapes a full set of medium inserts should be fitted.
1.13 OPERATION Cup Belt Agitators The cup belt agitators control the number of potatoes in a cup. When planting seed of good quality and size it is possible to drive faster without compromising planting accuracy. The agitation in this case can be kept to a minimum. If the seed is uneven the influence of the agitator can be increased by driving faster.
OPERATION 1.14 Setting the Automatic Depth Control (prior to 2013) Position the planter over the prepared bed. With the ‘AUTO DEPTH’ switch set to ‘OFF’, set the opener depth rams to their mid-stroke position using switches marked ‘OPENER RAISE/LOWER’. Set the planting depth using the switch marked ‘FRONT LIFT RAISE LOWER’. During work the opener parallel linkage arms should be approximately horizontal.

1.15 OPERATION Loosen the single screw on top of each sensor and flip open the access covers (see figure 15). The switch (item 1, figure 16) should be set to ‘PNP’ on both sensors. The switch (item 2, figure 16) should be set to ‘D’ for the ‘down’ sensor and ‘H’ for the ‘up’...
OPERATION 1.16 Hydraulic Space Selector Seed space setting is electronically selected on the space selector box (item 1, fig 17). The hydraulic circuit requires a supply from the tractor of a minimum 13.5 litres/minute (3 gal). The main components consist of the space selector box (item 1, figure 17), a master solenoid valve (item 1, figure 18) and 3 hydraulic motors (item 2, fig 18) fitted with bypass valves (item 3, figure 18).

1.17 OPERATION To check the ‘constant’ (no oil flow required): With ‘R’ depressed switch on the control box and then release ‘R’. The constant will appear in the LH display. Press the ‘Up’ or ‘Down’ arrow to increase or decrease the constant to ‘49’ for machines with 135mm cup belt centres, or ‘44’...
OPERATION 1.18 Calibrating the Control Box Area Recorder To ensure accuracy, the area recorder 'count' must be calibrated to suit the particular field conditions and also preference for information to be displayed in acres or hectares. The area recorder receives impulses from the wheel monitor which together with wheeling (bed width) information is processed into acres/hectares planted.
1.19 OPERATION Seed Spacing Press button selection is provided for 40 different seed spacings ranging from 10cm to 51cm (4" to 20"). The selected spacing is shown by the control box LH digits. To increase the spacing press the 'Up' arrow. To decrease the spacing press the 'Down' arrow.
OPERATION 1.20 Area Recorder The 'Area' button when pressed, provides a record of the number of acres/hectares that have been planted. This information is automatically stored by the memory bank after the wheelings have been programmed (see Seed Population). It can be accessed at any time by pressing 'A'.
If the seals become damaged it may be possible for dirt to enter the bearing causing accelerated wear. Use only the BP lubricants recommended by Standen or an exact equivalent recommended by your lubricant supplier.

MAINTENANCE 1.22 As the tractor supplies the oil for the machine’s hydraulics, ensure that the tractor hydraulic system is serviced in accordance with the manufacturer's recommendations to prevent any contamination of the machine’s system. To extend the life of the hydraulic components it is important to monitor the condition of the hydraulic oil.
1.23 MAINTENANCE Steering Ram Link Circuit The two rear axle steering rams are connected via a link circuit which ensures both rams actuate by equal amounts in opposite directions when turning. The link circuit diverts the oil within the annular section of the extending ram into the annular section of the ram opposite thus retracting that ram by the same amount.
Check metalwork for any damage or wear and repair or replace as necessary. Inspect wheel bearings and check for excessive wear, replace as necessary. Re-pack with fresh grease on re-assembly. Replace the pressure filter element. Use only genuine Standen replacement parts. THESE ARE NOT WASHABLE ELEMENTS.
1.25 MAINTENANCE Out of Season Storage The machine can frequently operate in soils which contain chemical fertilisers etc. When the working season is completed wash and clean the machine thoroughly prior to carrying out the following checks and operations. Apply oil, grease or an anti rust agent on any exposed bright metal surfaces which have been polished by the soil flow.

APPENDIX 1.30 Automatic Depth Control (from 2013) Automatic depth control of each pair of openers ensures that the desired planting depth is maintained irrespective of the contours of the bed. The ultrasonic sensor (item 1, fig 21) senses the height of the bed in front of the openers. The depth ram (item 2, fig 13) then raises/lowers the openers independently thus maintaining planting depth.
Page 36
1.31 APPENDIX Engage the auto-depth control by setting the switch marked ‘AUTO DEPTH’ to the ‘ON’ position. The LED will illuminate. If necessary re-adjust the height of the sensor leg to regain the desired planting depth. Drive forward and check the planting depth. Make further adjustments if necessary.
