2.4 Hitching Up2.4.1 Hitching up a Tractorto the SL / Preparing forTransport

When hitching-up the machine,ensure that no-one is between thetractor and the machine.

When the SL is parked for extendedperiods of time it should ideally beleft in the unfolded, i.e. work positionfor stability, safety and ease ofaccess for maintenance. However,parking the SL in the folded position(ensuring the transport lock isengaged) is acceptable in thenormal course of operation.

Tractor Oil Flow Adjustment:As a general rule the tractor oil flowrate should be set in the lowestsetting before starting. This can thenbe increased to allow the desiredrate of operation as applicable. Thiswill minimise excessive oil flow andconsequent power usage and heatgeneration.

1. Reverse the tractor up to the bar couplerand engage the link arms.

2. Ensure the tractor hydraulics aredepressurised and in the locked orclosed (not float) setting. Ensure theaxle taps are closed.

3. Couple the hydraulic hoses to the tractorensuring that the two wing hoses(yellow) are together and the lift cylinderhoses (red) are together.

4. Raise the front of the machine and movethe parking stand to the work position.

5. If the machine is already folded it is nowready for transport. If the machine isunfolded please refer to 2.5.2.

Ensure that the wing lock is engagedcorrectly before transporting themachine.

Disc Disc Tine Configuration


The SIMBA SL is an amalgamation of timeproven, successful Simba designedcomponents brought together to form thisimportant development. The SL has beendesigned and produced in conjunction withthe Simba ECOtillage™ system to provide aone pass mix with a fissured layer at discdepth for through drainage and root accessto lower horizons. This enables rapiddrainage and access after rain, creating agreater effective capacity for moisturecompared to ploughing for the same effectivetotal depth of cultivation.

In principle, the machine is an offset disc withTerra-Grip tines, designed for low draft, highspeed operations. The addition of a rearmounted roll enables effective cultivation inone pass. The leading set of disc bladescultivate the top horizon, minimising clodformation and reducing tine loadings andblockage. This starts the ‘top down’cultivation process, retaining weathered tilthin the surface level for stale seedbedpurposes. The front row of discs is thenfollowed by tines or a second row of discsdepending upon the machine configuration.The tines work to shatter at depth retainingthe surface intact to leave an ECOtillage™

stale seedbed. This eliminates the problemof ‘wet years’ in non-plough based terms. Thekey to the SL’s success are the tines whichmaintain shatter across the full width ofcultivation. The rear roll then consolidates thesurface, cracks any clods and firms the soilprofile after the rear gang completes mixingto depth. The corrugated top and shatteredlower horizons are left fully weatherproof toany conditions between cultivation and drillingwhilst retaining moisture below the surface forrapid straw breakdown and optimumestablishment of the next crop.



22


Fig. 4.04: Front Disc Gang

4.2 Disc UnitsThe SL features two rows of discs which chopand mix the crop residue. A disc spacing of250mm ensures a fine tilth.

The discs fitted to the SL are 500mm indiameter (20") and 6mm thick. They aremanufactured from heat treated chromeboron steel which ensures excellent wearresistance and enhanced working life. Eachdisc is mounted on a Pro-Flex sprung leaflinked to a track rod system. Gang anglescan be varied with ease and accuracy usinga graduated adjuster.

Adjustable angling of the discs (between 10°-25°) ensures penetration and stubble mixingare achieved in one pass. All this is achievedwithout compromise to consolidation.

A level, evenly cultivated finish is maintainedby adjusting the balance of soil throw betweenthe front and rear disc.

Sprung Pro-Flex leaves offer protectionagainst damage as well as offering a degreeof contour following as they flex up and downin work.

4.3 Terra-Grip TinesTerra-Grip tines have a robust, basicconstruction and are suitable for all soil types.

The spring-loaded auto-reset system with a500kg trip force on each tine preventsdamage to the tines and tine brackets.

When the auto reset system is activated aninitial progressive phase holds the tine in theground in a steady position until the trip pointis reached. In the subsequent springcompression phase the tine is raised gentlyand rapidly to a maxmum height of 230mm.

The tines can be fitted with a selection of pointsdepending on application and have 6 depthsettings in 25mm increments down to amaximum working depth of 250mm..

Fig. 4.05: Terra-Grip Tines



Fig. 4.06: DD Light Roll

4.4 DD Light RollerThe DD Light roller is made up of individualDouble Disc (patented) Ring segments.

The DD Light roll is designed to consolidatethe soil whilst cutting and crushing any clods.

Even in heavy, wet soils it can easily beoperated with minimal blockages occurring.

The rear DD Light roller carries a proportionof the machine’s weight to ensureconsolidation. It also regulates the depth ofthe disc units. The corrugated surface left bythe roller is weatherproof both for wet or drysituations.

4.5 Work SettingsOptimum performance has been found to beachieved when the DD Light roll rings haveworn away the painted finish leaving a smoothshiny surface. When the DD Light rings arenew or rusty, soil may tend to pick up on thesurface and blockage may occur, this willreduce when the rings are shiny again.

The SL should be run with the chassis level toslightly tail low. In practice it is possible to usethe SL on ground conditions that areunsuitable to achieve the desired effect, andit is usually possible to operate the DD Lightroll without regular blockage under suchunsuitable conditions, assuming that the rollassemblies are tight, the scrapers correctlyadjusted and rings smooth. As such,especially under wet conditions, it is advisableto check on the cultivation effect of the SL.

The SL should be lifted fully clear of the groundon the transport wheels for all headland turns.Turning with the disc units or roller on theground could lead to damage of thesecomponents.

In work, the tractor link arms should be usedin conjunction with the rear roll to determineworking depth / pitch.

4.6 Starting SettingsThis section details the recommended start-ing settings for the SL. These settings canthen be used as a base for further adjustmentin order to get the optimum performace fromyour machine.

Ensure all settings from the left and right handsides of the machine match each other.

4.7 Adjusting DepthTo change the working depth it is advisableto lift the machine clear of the ground so thatthe rear roll linkage becomes loose. Thedepth is changed by adding shims above andbelow the collar on the depth control rod.

When the depth has been altered, lower themachine into work and check operation. Ifthe depth change has been significant thenother settings could be affected. This couldbe chassis pitch (front to rear) and disc anglefor the given depth.

A small amount of cultivation, eg. a 20 metrerun, should be carried out before alteringthese settings to check whether they are nowsuitable for the cultivation effect required.These settings should be addressedimmediately to prevent too muchunsatisfactory work being carried out.

4.8 Work InstructionsDriving speedThe SL can be driven at speeds of up to 12km/h.

This depends on the field conditions (type ofsoil, surface trash, etc.).

Drive more slowly if the conditions are difficultor a firmer finish is required.

Turning:Before turning, the machine shouldbe eased fully out of work onto thetransport wheels while movingforward. Likewise, it should easedback into work once the turn hasbeen completed. Do not attempt toturn the machine on the roll.

4.9 Parking the machineIn order to avoid damage as a result ofmoisture, the machine should be parked, ifpossible, indoors or under cover.

When manoeuvring the machine,pay attention to your surroundings.Ensure that nobody is in themanoeuvring area (watch forchildren!).

• Park the machine on level and solid ground.• Raise the machine and lower the parkingstand.• Lower the machine to the ground, ensuringthat it is stable.

When parking with the machineunfolded, ensure that no load iscarried by the Terra-Grip tines.This can lead to breakage of thepoints.

• Disengage from the linkage and driveforward slowly until the tractor is clear.• Switch off the tractor.• Disconnect hydraulic lines from the tractor.

4.10 ChecksThe working quality depends on theadjustments and checks made prior to andduring work, as well as on regular servicingand maintenance of the machine.

Before beginning work it is thereforeimportant to carry out any necessary servicingand to lubricate the machine as required.

Checks prior to, and duringwork:• Is the machine correctly hitched up and thecoupling device locked?• Have the hydraulic lines been connectedaccording to the colour coding?• Is the machine in a level operating positionand the working depth set correctly?

Working Elements• Are the discs and other cultivation tools in aserviceable condition?• Are the scrapers still operable, so that therolls do not jam?



5. Servicing andMaintenance

Follow the safety instructions forservicing and maintenance.

5.1 ServicingYour machine has been designed andconstructed for maximum performance,operational efficiency and operatorfriendliness under a wide variety of operatingconditions.

Prior to delivery, your machine has beenchecked at the factory and by your authoriseddealer to ensure that you receive a machinein optimum condition.

To ensure trouble-free operation, itis important that servicing andmaintenance work is performed atthe recommended intervals.

5.2 CleaningIn order to ensure that the machine is alwaysin operating condition and to achieveoptimum performance, perform the cleaningand servicing work at regular intervals.

Avoid cleaning the roll / disc bearings with ahigh- pressure hose or a direct water jet. Thehousing, screwed connections and ballbearings are not watertight.

5. Servicing and Maintenance

5.3 Disc Hub Maintenance

Grease every disc hub untilgrease shows from the sealsaccording to the lubricatingintervals outlined on page 31.

Check disc hubs regularly fortightness.

Regularly examine hub caps, sealsand pivot bolts and all tracking boltsfor tightness and effectivenesstwice weekly or every 50 workinghours (whichever is more frequent).

Fig. 5.01: Checking Disc Bearing Adjustment

1 Ensure that the bearing seal is in thecorrect orientation when replacing /assembling components.

2 Ensure that the stub axle is free fromdirt and the nut and outer bearing caneasily slide on it.

3 Tighten the crown nut with a handspanner (a torque wrench is notrequired) while turning the hubclockwise until the bearing drags slightly(you feel the hub turning heavily). Someresistance will be due to friction from theseal.

4 Turn back the crown nut to the nextlocking position. Even if the tighteningof the nut has reached an exact fixingposition, turn it back.

5 Insert the retaining pin.

6 Try to shake/rock the outer edge of thehub/spindle: play of 0.1 / 0.2mm will notreduce the bearings’ life and, in addition,prevents overheating. If the adjustmentis correct the hub should turn freely withthe only friction being from the seal.

5.3.1 Tightening Disc Hubs

5.5 DD Light RollThe spacers and rings on the DD Light Rollare held under tension by the end plates atthe outer ends of the roll tube.

Specialist equipment is requiredfor the disassembly of DD Lightrollers. Please consult your dealerunder any circumstances thatrequire disassembly of theseaxles.

Maintenance of these rollers is limited toyearly/end of season greasing of the bearingsand regular inspection to ensure theassemblies are tight, and scrapers arecorrectly set.

The scraper is intended to clear dirtfrom blocking between adjacent DDrings. If adjustment to the scrapersis required ensure that the scrapercannot contact the spacer evenunder load. Regularly inspect thespacers for signs of wear and adjustany scrapers to ensure no contactcan be made.

5.4 Terra-Grip Tine PointsTine maintenance should beperformed with the machine fullyraised and with all taps closed.

When working under the machineensure that the tractor handbrakeis on.

When changing points on Terra-Grip tines extreme care should betaken. Wear goggles at all timeswhen changing tine points.

5.3.2 Bearing SealsIt is important when replacing the labyrinthtype bearing seals in disc hubs that the sealis fitted the right way round. The chamferedlip side should be at the outside of the bearinghousing, nearest the disc arm (see Fig. 5.02).This chamfered lip prevents dirt ingress intothe housing and also allows grease to beflushed though when greasing.

5.6 Brakes & Wheel HubsThe brakes should be tested before using forthe first time and after the first laden journey.

Check that the road and parkingbrakes operate and releasecorrectly before using the machine.

Check for hydraulic fluid and airleaks.

Brake and hub maintenance andservicing should be carried out byan authorised Simba dealer.


5.7 Hydraulics

A low oil flow should be used, i.e.,tractor tickover or low flowselected.

The wing circuit is controlled by anovercentre valve contained withinthe manifold block which positivelylocks oil flow until pressurised bythe tractor. System pressure canbe retained in the circuit even afterdepressurisation of the tractorquick release couplings.

Exercise extreme care whenchecking the valve or circuits, andunder no circumstances attemptto adjust or loosen fittings withoutprior reference to your authorisedSimba dealer, and detailedmaintenance instructions.

The hydraulic circuit containsspecialised fittings which shouldnot be tampered with under anycircumstances. Do not attempt tomodify hose routings or hoseclamping arrangements, doing somay cause serious damage to themachine and/or injury.

5.9 Operator SupportIf you have a problem, please contact yourdealer. They will endeavour to solve anyproblems which may occur and provide youwith support at all times.

In order to enable your dealer to deal withproblems as quickly as possible, it helps ifyou can provide them with the following data.Always state the:

• Customer Number• Name and Address• Machine Model and Serial Number• Date of Purchase and Operating Hours• Type of Problem

5.8 Preparation forStorageIf you need to store the machine for a longerperiod, observe the following points:

• Park the machine undercover if possible.• Protect the roll / discs against rust. If youneed to spray the implements with oil, uselight biologically degradable oils, e.g. rapeoil.

Cover any rubber sections beforeusing oil sprays. These sectionsmust not be oiled. Remove anytraces of oil with a suitable cleaningagent.

Avoid sharp-edged and pointedparts (disc blades, etc.) whenworking on the machine.

5.10 MaintenanceIntervalsApart from daily maintenance, themaintenance intervals are based on thenumber of operating hours and time data.

Keep a record of your operating hours toensure that the specified maintenanceintervals are adhered to as closely aspossible.

Never use a machine that is due formaintenance. Ensure that all deficienciesfound during regular checks are remediedimmediately.

Place the machine on suitablesupports when workingunderneath! Do not work under amachine which is not supported!

On a new machine tighten all nuts and boltsafter 5 hours work and again after 15 hours.This also applies to parts that have beenmoved or replaced. After the initial 15 hoursof work a once a week check should besufficient depending on daily work rates.

Always exercise extreme care and observethe recommended hygiene rules whenhandling mineral oil products. Details of thesehandling regulations can be found ininformation provided by the health authorities.

Storage and Handling• Always store lubricants where they cannot beaccessed by children.• Never store lubricants in open or unlabelledcontainers.

Fresh Oil• Apart from taking the usual care and obser-ving hygiene rules, there is no need to takeany special precautions when handling freshoil.

Waste Oil• Waste oil can contain harmful contaminantswhich may cause skin cancer, allergies andother illnesses.

Attention!Oil is a toxic substance. Should you swallowany oil, do not try to vomit. Contact a doctorimmediately.Protect your hands with barrier cream or weargloves to avoid contact with the skin. Washoff any traces of oil thoroughly with soap andhot water.

• Wash your skin thoroughly with soap and water.• Use special cleaning agents to clean anydirt off your hands.• Never wash oil residue from your skin withpetrol, diesel fuel or paraffin.• Avoid skin contact with any oily clothing.• Do not keep any oily rags in your pockets.• Wash soiled clothing before wearing itagain.• Ensure that any oily footwear is disposed of inthe proper manner.

5.13 Lubricating theMachinePlease read the section entitled "UsingLubricants" carefully before lubricating themachine.The machine must be lubricated regularly inorder for it to remain serviceable. Regularlubrication also contributes towards extendingthe service life of your machine.The recommended lubricating intervals arespecified in "Inspection" and "MaintenanceIntervals".

After it has been washed using a high-pressure hose or steam cleaned, the machineshould always be lubricated using a greasegun. Ensure that the universal joints andsplined shafts are lubricated regularly.

5.14 Handling ofLubricantsPlease ensure that you read the followinginstructions as well as the relevantinformation. This also applies to any of youremployees who handle lubricants.

HygieneLubricants do not present a health hazardprovided they are used for their specifiedpurpose.

In the case of prolonged skin contact,lubricants - especially low-viscosity oils - mayremove the natural layer of fat contained inthe skin, resulting in dryness and possibleirritation .

It is important to take extreme care whenhandling waste oil as it may contain otherirritants.

Vapours given off by cleaning agents and oilsare also a potential health hazard.You should therefore not carry any oily clothsaround. Change soiled work clothing as soonas possible.




Measures in case of injurythrough oilEyes:Should any oil be splashed into your eyes,rinse with water for 15 minutes. If the eye isstill irritated, contact a doctor immediately

If oil is swallowedIf oil is swallowed, it is important not to inducevomiting. Contact a doctor immediately.

Skin irritation caused by oilIn case of prolonged skin contact, wash offthe oil with soap and water.

Oil SpillsUse either sand or a suitable granularabsorbent to soak up any spilt oil. Dispose ofthe oil-contaminated absorbent in the propermanner.

Oil FiresNever use water to extinguish an oil fire. Theoil will float on the water causing the fire tospread.

Burning oil/lubricant must be extinguishedusing a carbon dioxide powder or foamextinguisher. Always wear respiratoryequipment when dealing with fires of this type.

Waste Oil DisposalOil-contaminated waste and used oil must bedisposed of in accordance with currentlegislation.

Waste oil must be collected and disposed ofin accordance with local regulations. Neverpour used oil into unsealed sewage systemsor drains or onto the ground.

5.15 Lubricants &Hydraulic OilHydraulic SystemThe hydraulic fluid from the tractor is mixedwith the hydraulic fluid from the machine.

The supplied machine hydraulic systemcontains Total AZOLLA ZS 32 oil.

LubricantsSimba strongly recommend the use ofLithium Complex EP2 Grease in the discand wheel hubs of your SL. This grease isa Lithium Complex soap dispersed in a min-eral oil and is interpreted by IARC as beingnon-carcinogenic. Grease cartridges areavailable from Simba (P12710). Using thisgrease in combination with the labyrinth typeseal it is permissible to lengthen the greas-ing interval on the disc hubs to 200 hours.If using a standard agricultural grease thedisc hubs should be lubricated every 50hours.

All other lubricating points on the machine canbe lubricated with multigrade lubricatinggrease as specified in DIN 51825 KP/2K -40.

Advantages of Lithium Complex EP2Grease

Excellent mechanical stability.Excellent load carrying properties.Wide temperature range.Excellent oxidation stability.Excellent water resistance.Compatability with other greases.
