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 STANDEN ZENO 2-row and 3-row tractor mounted planters are designed to plant potatoes with extreme gentleness and accuracy in either standard planting or bed work. Tractor Suitability The ZENO planter is suitable for CAT 2 and CAT 3 tractors of 75 Kw (100 bhp) minimum with open-centre, closed-centre or load-sensing hydraulic systems..

INSTALLATION Mount the control console in a position where it is comfortable to operate when seated. An adjustable suction mount is fitted to attach the console to the side window of the tractor. Care should be taken to ensure the control box does not obstruct driver visibility and access to the tractor controls.
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 1.10 Land Wheels The land wheels can be either fixed or steerable. A proximity sensor fitted to the RH wheel axle monitors the forward speed of the planter. On machines with steerable wheels, a wheel indicator is fitted to assist the operator. The land wheels must be set to straddle the rows.
1.11 OPERATION Row Centres Row centres can be set between 30” (76cm) to 40” (102cm) on a 2-row machine, and between 16” (41cm) to 18” (46cm) on a 3-row machine. WARNING: Always lock the raised hopper with the stays (item 2, fig 8) before working underneath (see tipping hopper).
OPERATION 1.12 Tipping Hopper The rear section of the tipping hopper (item 1, fig 8) is designed to gently feed the potatoes into the hopper belts. Sensors can be fitted inside the hopper to detect the level of seed above the hopper belt feed area. On automatic mode the sensors raise the rear section of the hopper automatically.
1.13 OPERATION Fig 9 Hopper Belts The hopper belt (item 1, fig 10) conveys the seed potatoes from the hopper to the singulating belts (item 2, fig 10). The regulator plate (item 1, fig 11) should be set to keep a single layer of seed covering the hopper belt. Lowering the regulator plate too much could result in ‘bridging’...
OPERATION 1.14 Singulating Belts The singulating belts (item 2, fig 10) consist of one fast belt and one slow belt arranged in a V-format. The action of the fast and slow belts sorts the potatoes into a continuous, single line before feeding them onto the trough belt. The belts on the RH unit are each fitted with a proximity sensor (item 1, fig 12) which monitors their speed.
1.15 OPERATION Seed Placement Belt The height and angle of the seed placement belt (item 2, fig 13) relative to the trough belt (item 1, fig 13) should be set to allow the pintle fingers to grip the seed. If set too low, the belt may crush the seed.
OPERATION 1.16 Soil Retention Panels The soil retention panels (item 1, fig 14) prevent soil flowing from the openers into the wheelings. To adjust, loosen the front support clamp (item 2, fig 14) and the rear support clamp plate (item 3, fig 14) and move the retention panel unit in or out to the desired position.
1.17 OPERATION Ridger Bodies (optional) The ridger bodies (item 1, fig 16) create the sides of the bed. The ridgers are positioned by loosening the retaining bolts (item 2, fig 16) and sliding the units along the tool bar. The height of each ridger is adjusted by loosening the clamp bolts (item 3, fig 16) and then raising or lowering the unit.
OPERATION 1.18 Bed Forming Board (optional) The bed forming board (item 1, fig 17) operates between two ridger bodies. The board creates a flat top on the finished bed. The board extensions (item 2, fig 17) are adjusted in conjunction with the ridger bodies. The position of the ridgers is important to ensure a nicely formed bed.
1.19 OPERATION Control System The control console consists of the Z-PAD touch screen (item 1, fig 20) and various manual switches. POWER ON/OFF (item 2, fig 20). Turns the control system ON and OFF. STEERING LEFT / RIGHT (item 3, fig 20). Steers the planter wheels left / right.
OPERATION 1.20 Setting Up The Control System Turn the control system ON. When fully powered up, the ‘home’ screen will display (see fig 35). To ensure the calculations for seed spacing and seed coverage are correct, the following information must be set. Press the icon once.
1.21 OPERATION Calibrating The Control System To ensure the seed is planted at the correct spacing the control system will need to be calibrated. The system should always be re-calibrated when changing seed size. To calibrate the system: Press the icon .
OPERATION 1.22 Manual Hydraulic Depth Control (optional) On the ‘home’ screen (see fig 35) press the UP and DOWN arrows to hydraulically change the seed planting depth. To plant shallower press the UP arrow. To plant deeper press the DOWN arrow. Automatic Hydraulic Depth Control (optional) Automatic depth control ensures the preset planting depth is maintained irrespective of the contours of the bed.
1.23 OPERATION Hopper Belt Speed and Delay The hopper belts should move slowly, just enough to keep the singulating belts supplied with a manageable quantity of seed. Achieving the correct speed and flow is a matter of trial and error. Press the icon .
. The ‘diagnostics’ screen will display (see fig 58). Use the arrows to scroll through the various diagnostics pages. Press the icon . The ‘valve value’ screen will display. The information contained in these screens is helpful to Standen’s service department when diagnosing a problem.
1.25 OPERATION Converting from 3-Rows to 2-Rows The 3-row planter can be converted to 2-row by deactivating the centre row. Remove the centre opener and the opener leg. Fit the centre row cover plates as shown in the parts book (see page 3.5). Fit the correct combination of moulding board / ridgers.
MAINTENANCE 1.26 Belt Tension The belts should be tensioned just enough to keep them driving under load. Do not over-tighten the belts as this will cause premature wear. Always adjust both sides of the belt equally, Fig 23 Fig 24 The hopper belt and singulating belt tensioners are spring-loaded.
1.27 MAINTENANCE Drive Chain Tension The drive chains should be tensioned to give a positive drive without undue stretching. To tension the hopper belt drive chain (item 1, fig 26) reposition the nylon tensioner (item 2, fig 26). The tensioner will initially show fairly rapid wear but will settle down when the chain rollers rather than the chain side plates come into contact with the plastic.
MAINTENANCE 1.28 Electrical System Maintenance The components within the electrical system are designed to be maintenance free. If it becomes necessary to carry out any repair, only a competent engineer capable of this type of work should carry out the repair. Periodically ensure that all multi pin plugs are correctly fitted into their sockets and are not becoming loose.
A suitable chain lubricant or a smear of grease should be regularly applied to drive chains to prevent wear. Use only the BP lubricants recommended by Standen or an exact equivalent recommended by your lubricant supplier. Medium grease = BP...
Check metalwork for any damage or wear and repair or replace as necessary. Inspect wheel bearings and check for excessive wear, replace as necessary. Replace the pressure filter element. Use only genuine Standen replacement parts. THESE ARE NOT WASHABLE ELEMENTS.
1.31 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.
