DRIVINGP11NE231TRAILER HYDRAULIC BRAKESConnect the trailer or semi-trailer hydraulic brakes with the quick coupler marked withan arrow.The control of the trailer (semi-trailer) hydraulic brakes and the control of the tractorbrakes ensure synchronized braking effect of both the vehicles. Working pressure isenforced by oil supplied from the hydraulic gear-type pump that works permanently.The trailer brake control valve is controlled by brake fluid pressure from the mainbrake cylinders depending on force that influences the brake pedal. Upon maximumpressing down the brake pedal, pressure on the coupling head should be 12 - 15MPa. The trailer brake valve prefers the brake function to the hydraulic function.In the event of shocks when you press down the brake pedal, you have to bleed thehose from the brake valve to the quick coupling.When driving with trailer, the brake pedals should be connected and safeguardedwith a lock!When braking with one brake pedal, the trailer hydraulic brakes are outof operation.CONNECTION AND DISCONNECTIONOF QUICK COUPLINGS OF THETRAILER HYDRAULIC BRAKESWhen connecting and disconnectingthe quick couplings youshould be aware of the rest of oilthat is kept in the quick couplingplug or socket.To protect environment you haveto remove the oil residues aftereach disconnection of the quickcouplings with a textile rag.60

HYDRAULIC SYSTEMP11N001HYDRAULIC SYSTEMIt consists of the inner and outer circuits.Gear pump is the source of pressure oil.Oil is taken from reservoir shared bygearbox and transmission.Hydraulic pump cannot be switched off.If the engine is working, the pump is on.The amount supplied is 50 liters perminute.The pressure in hydraulic system raisedby the hydraulic pump is restricted by asafety valve to 19 MPa.82
HYDRAULIC SYSTEMP+11N001HYDRAULICS CONTROL PANELHydraulics control panel is located in thearea of the right wing.Controlling the rear three-point hitch isenabled by the inner hydraulic circuit (1).Controlling outer hydraulic circuits(couplers) is enabled by outer hydrauliccircuit (2).P+11N002WAYS TO REGULATE INNER HYDRAULIC CIRCUITHydraulic system allows of three ways to regulate the lifting of the rear three-pointhitch:Position regulation (img. 1) – the tool connected to the rear three-point hitch isautomatically kept in the same height (position) with regard to the tractor.Mixed regulation (img. 2) – a combination of position and power regulation. Suitablemainly for tilling areas of different soil resistance.Power regulation (img. 3) – the tool connected to the three-point hitch isautomatically being adjusted depending on changing soil resistance.All the regulations can also be used when working with a tool equipped with asupport wheel in so-called free (floating) position.83

After pushing the lever towardsyou, the lever can be moved over theadjustable stop.84
HYDRAULIC SYSTEMP+11N006THREE-POINT HITCH LOWERINGSPEED CONTROLThree-point hitch lowering speed control(3) selects the speed of lowering thearms of the rear three-point hitch.Turning the knob in (b) direction reducesthe lowering speed of the arms of therear three-point hitch, turning it in (a)direction increases the speed. If the knobis turned in (b) direction to its stop point,the arms of the rear three-point hitchcannot be lowered.E408HYDRAULIC SYSTEM SENSITIVITYCONTROLHydraulic system sensitivity control (4)adjusts the sensitivity of the hydraulics inpower or mixed regulation. Turning theknob in (a) direction increases sensitivity,turning it in (b) direction decreasessensitivity.85
HYDRAULIC SYSTEMP+11N008POSITION REGULATION OF THE LIFTING OF THE REAR THREE-POINT HITCHPosition regulation of the lifting of the rear three-point hitch means that the tool connected to the rear three-point hitch isautomatically kept in the same height (position) with regard to the tractor.Move lever (1) to the front position (d). Adjust the height of the rear three-point hitch with tools within the (b) range by lever (2).Adjusting the height is smooth within the range 1-9. In position 1, the arms of the rear three-point hitch are in the lower position, inposition 9, in the highest position. Position (c) is a transport position when the tools connected to the rear three-point hitch israised at maximum.To transport tools which are connected to the rear three-point hitch always use position regulation.To raise tools into transport position, turn the three-point hitch lowering speed control knob (3) in the direction shown bythe arrow up to the stop point, which results in interrupting the oil flow in hydraulics. Should tools connected to the rearthree-point hitch not be lowered, check the position of the speed lowering control knob (3) – turn it in the oppositedirection than shown by the arrow.If tools connected to the rear three-point hitch are long and heavy, the arms of the rear three-point hitch may get locked inthe transport position during transport. If the lowering speed control knob (3) is loosened and the tools still cannot belowered, move lever (2) to the floating position (c) for a short time and immediately get back to the lowering range (d). Thearms of the rear three-point hitch start to go down as set by lever (2).86
HYDRAULIC SYSTEMP+11N010POWER REGULATION OF THE LIFTING OF THE REAR THREE-POINT HITCHPower regulation of the lifting of the rear three-point hitch means that the tool connected to the rear three-point hitch isautomatically being adjusted depending on changing soil resistance.Set the adjustable stop (5) to a position on the edge between floating position and the beginning of the range of lifting of the rearthree-point hitch.Move lever (2) to (f) position – to the adjustable stop (5).Move lever (1) to (g) position, accelerate the tractor and move lever (1) in the direction shown by the arrow to set the depth oftilling (in (g) position, depth is the lowest).Once the depth of tilling is set, lever (1) must be kept in constant position. At the end of each row, raise the tool connected to therear three-point hitch only by moving lever (2) to (e) position. To lower the tool to its operating position again, move lever (2) to (f)position.The rear three-point hitch may start oscillating under the influence of changing soil resistance. To reduce oscillation, setlower hydraulic system sensitivity by turning the control knob (4) in (b) direction.87
HYDRAULIC SYSTEMP+11N011MIXED REGULATION OF LIFTING THE REAR THREE-POINT HITCHMixed regulation of lifting the rear three-point hitch means that the tool connected to the rear three-point hitch is automaticallybeing adjusted depending on changing soil resistance and at the same time it prevents any increase in depth of tilling in case ofsmaller soil resistance.Set the depth of tilling by lever (1) as described in “Power regulation of the lifting of the rear three-point hitch“. Then start movinglever (2) in the direction shown by the arrow until the arms of the rear three-point hitch start to rise slightly. Herewith, mixedregulation has been set. Move the adjustable stop (5) to lever (2) which has been set and lock it. At the end of each row, raise thetool connected to the rear three-point hitch only by moving lever (2) to (e) position. To lower the tool to its operating positionagain, move lever (2) to the preset stop.88
HYDRAULIC SYSTEMP+11N016EXTERIOR REAR HYDRAULIC ARMS CONTROLSExterior rear hydraulic arms controls are located on the rear right wing. They make iteasier for the operator to conncet tools by controlling the movements of the lowerdrawbars of the three-point hitch from the outside. They only serve for conncetingand disconnecting the tools.Img. (A)Before using exterior controls, move the power regulation lever (1) to its utmostposition.Lowering hydraulic arms img. (B):Move lever (3) in the direction shown by the arrows (moving the lever is restrictedwith a link). By repeating this procedure, hydraulic arms are lowered in small steps.Raising hydraulic arms img. (C):Move lever (3) in the direction shown by the arrows (moving the lever is restrictedwith a link). By repeating this procedure, hydraulic arms are raised in small steps.If the lifting device controlled by exterior controls is loaded, movement of thelower drawbars within one step (on the exterior controls) is longer than ifunloaded.P+11N012OUTER HYDRAULIC CIRCUITIt supplies pressure oil for hydraulicdevices on outer drives of hydraulicsended with couplers. Coupler socketswith 12.5 mm bore are in accordancewith the international recommendation ofISO.89

HYDRAULIC SYSTEMCONNECTING MACHINERY AND TOOLS TO OUTER HYDRAULIC CIRCUITConnecting a double acting cylinderA double acting cylinder must always be connected to quick couplers of one section.Connecting machinery and tools assembled from more partsWhen working with agriculture machinery which is assembled from more parts (combinators, scrubbers, or harrows) where theedge frame is hinged to the central frame because it is diagonally folded during transport by independent hydraulic cylinderswhich are controlled by outer hydraulic circuit of the tractor, it is recommended to connect the lifting arms of the cylinders to quickcouplers (3) and (5) which are equipped with a one-way valve.Connecting rotary hydraulic engineIf a hydraulic engine is connected to outer hydraulic drive, it is always necessary to connect its returnable arm to quick coupler(0). Filling (pressure) arm can be connected to quick couplers (1) or (2), where the hydraulic engine is protected by the “kick-out”function from overload. This function stops the hydraulic engine if pressure in the filling arm exceeds 17 MPa.Connecting reverse rotary hydraulic engineDue to its function, reverse rotary hydraulic engine must be connected to quick couplers of one section. It is recommended to usequick couplers (1) and (2), where the hydraulic engine is protected by the “kick-out” function from overload. This function stopsthe hydraulic engine if pressure in the filling arm exceeds 17 MPa. If the hydraulic engine is connected to quick couplers ofdifferent sections, both arms must be equipped with safety valves which can be relied on to restrict high pressure peaks duringrun-out. Connect the safety valves drain to quick coupler (0).Connecting external hydraulic distributorIt is recommend to connect external hydraulic distributor to quick couplers (4) or (6). Control levers (b) and (c) are mechanicallylocked in these positions without hydraulic lock.Connectable machinery which makes use of oil in outer hydraulic circuit must be filled with the same kind of oilas recommended for tractor gearbox!Quick coupler sockets of connectable machinery must be cleaned properly before connecting.97

Lower pull rods100728mm28mm25mm870mm28mm25mmG452SAFETY PRINCIPLES WITH WORKWITH A THREE-POINT HITCHThe persons not charged withwork with an implement to thetractor may not stay between thetractor and hitched mechanism(implement) - (A).Do not park the tractor withhitched implement in lifted position(B).When driving without any implementit is necessary to couplelower pull rods (5) using springsand set the upper pull rod (1) intothe flexible hitch! For transport ofan implement the limiting pullrods (4) shall be adjusted to preventany undesired side movementsof the implement!
HITCHESHEIGHT ADJUSTMENT OF LIFTINGPULL RODSLifting pull rod see fig. (A):Perform adjustment by turning of the eye(1) after disconnection of the upper end ofthe lifting pull rod.Lifting pull rod see fig. (B):Pull out the arm cross (2) in direction ofthe arrow and perform adjustment byturning of the arm cross.According to equipment of the tractorboth pull rods can be arranged as shownon fig. (B)E453 E454 E455FIXED AND FREE POSITION OFLOWER HYDRAULIC PULL RODSFixed position of lower hydraulic pullrods see fig. (A):The pin head (1) and washer (2) aremounted horizontally.Free position of lower hydraulic pull rodssee fig.(B):The pin head (1) and washer (2) aremounted vertically.Free position allows free coupling of thetractor and implement. Both ends of thepull rods may move freely each other inthis case.LIMITING PULL RODSThe limiting pull rods (1) allow sideswings of the lower pull rods.The left and right limiting pull rods can beadjusted by turning of the pull rod pipe,see the arrow.Both limiting pull rods shall alwaysbe mounted on the tractor.101
HITCHESUPPER PULL RODLength of the upper pull rod (1) is adjustable.The pull rod can be connected tothe tractor to one of four holes in thebracket that transfers forces from thehitched implement to the torsion rod inthe cover of the hydraulics regulation.When transporting an implementit is necessary to reposition theupper pull rod to the hole “d“ toprevent overloading of the liftinghydraulics kinematic systém orfall of the hitched mechanism.P11NE456 E457 E458UPPER PULL RODWhen extending the upper pullrod it is necessary to payattention that both joints arescrewed out from the pull rodpipe in the same length.SELECTION OF HOLES IN THEBRACKETConnection of the upper pull rod to someof the holes "a" to "d" of the bracket influences:- Sensitivity of hydraulics regulation(selection lever of the system in position"D" or "M"). Sensitivity is highest whenthe pull rod is connected to the hole"a".102
HITCHES∗LOWER PULL BARS WITHEXTENSIBLE TERMINALSThe lower pull bars of the hitch are providedwith semi-automatic extensibleterminals CBM. These terminals facilitatecoupling of the implement to the tractor.After pulling out the locking pins (1) pushout the terminals (2). The pushed outterminals can be then attached to the fixingpins of the carried implement.After attaching the carried implement releasethe hydraulic arms. By loweringthem and reversing the tractor the terminals(2) slide into the pull bars and lockthemselves automatically in the workingposition using the locking pins (1).Check always position of extensibleterminals and locking pins,see fig. (3).E459 E460 X901∗LOWER PULL BARS WITH HOOKSCBMThe lower (3) and upper (4) pull bars ofthe hitch are provided with hooks CBM.First the implement shall be completedwith hitch balls CBM (1) and adjust thedistance between lower pull bars of thehitch (3) using the limiting pull bars.By reversing of the tractor and slight liftingof the three-point hitch its lower pullbars (3) are connected to the implementand the upper pull bar (4) of the threepointhitch is then connected by thedriver from the cabin.When uncoupling the implement, unlockthe hooks, lift the upper pull bar (4) usingthe control stranded wires and disconnectthe lower pull bars (3) by lowering ofthe three-point hitch.103BLOCKING OF LOWER LINKAGESWITH CBM HOOKSFor very difficult working conditions(aggregation with heavymachines on slopes or aggregationwith side loaded machines)we recommend to lock the lowerlinkage hook by inserting of a M8bolt to the orifice (S) and blockingof the bolt with a nut.
HITCHESE461∗FRONT THREE-POINT HITCHIt is designed for coupling of front-carriedfaming mechanisms and implement ofcategory II according to ISO.When transporting a carriedimplement it is always necessaryto secure the hitch lifted positionhydraulically using the valves that arelocated on the left side of the tractorabove the front axle.This hydraulic locking is recommendedeven in case that there is not coupledany mechanism to the three-point hitch.X463ADJUSTMENT OF LIFTING SPEED OFTHE FRONT THREE-POINT HITCHBefore commencement of work with theimplement attached to the front threepointhitch it is recommended to adjustthe throttling valve (3) so that the timenecessary to lower the implement fromthe highest to the lowest position is 1 to1.5 second. Rotation of the valve bodycounterclockwise (in direction of the arrow)the lowering speed increases. Duringadjustment the front hitch valve leversshall be in horizontal position.104
HITCHESP+11N021COTROLLING FRONT THREE-POINT HITCHThe hitch is equipped with two single acting hydraulic cylinders which are suppliedwith oil from an additional hydraulic distributor. To lift or lower, use lever (b) of theadditional distributor.3 position lifting4 position loweringN position locking the hitchP position not to be usedIf the tractor is equipped with front three-point hitch, use lever (b) to control it.When the front three-point hitch is used, quick couplers cannot be connectedas they are pressured together with the front three-point hitch! When you finishusing the front three-point hitch and want to use the section with quick couplers3 and 4 with connection to the front three-point hitch, raise the arms ofthe front three-point hitch to the transport position and move the front threepointhitch lever to the „locked“ position.105

Release the screw (7) by 5/6 of turn,check free rotation of the wheel andlock the screw (7) using the nut (6).6. The adjustment procedure is thesame for the left and right wheels ofthe tractor.E763174
In case that some asymmetry of brakingbetween the left and right brake occursafter such adjustment, it is necessary torelease the adjustment screw (7) of thatbrake that brakes more intensively up tothe moment when braking effects of bothwheels are balanced; however, it is allowedto release the screw max. by 1/2of turn. In case that even after this readjustmentthe asymmetry of braking continues,it is necessary to adjust thebrakes of the tractor in an authorised repairshop.ADJUSTMENT OF HAND BRAKE1. Adjust the lever (4) so that the distancebetween the bracket (K) andface of the fork on the lever (4) is109mm (the lever (4) should form anangle 20° with vertical plane).2. Screw in the nut (2) onto the contactsurface of the pin (3) without any playand pre-stress – the arms (5) shall notbe squeezed.3. The adjustment procedure is identicalfor the right and left sides of the tractor.4. Using the nuts (8) adjust the handbrake lever Bowden so that at angle20° on the lever (4) the hand brakelever is without any play.5. Lift and lower the hand brake lever (1)several times to eliminated any possibleplays between the components.ADJUSTMENTS6. Check adjustment of the hand brakesystem and if necessary, correct theadjustment and check tightening of alllocking nuts (6), (8).In case that some asymmetry of handbrake effect between the left and rightbrake occurs after such adjustment, it isnecessary to release the adjustment nut(2) of that brake that brakes more intensivelyup to the moment when braking effectsof both wheels are balanced; however,it is allowed to release the nut (2)by 1.5 of turn. In case that even after thisreadjustment the asymmetry of brakingcontinues, it is necessary to adjust thebrakes of the tractor in an authorised repairshop.Note: Adjustment holes are on the floorof the tractor cabin to facilitate adjustmentof the brakes.175C754ADJUSTMENT OF FREE TRAVEL OFBRAKE PEDALSCorrect play between the piston rod ofbrake pedal and the piston of main brakevalve is 0,5-1,0 mm (3 - 6 mm whenmeasured at the edge of the brake pedalsat unlatched pedals). Adjust the playat unlatched pedals and after releasingof the adjusting nut (1), in which the pistonrod is screwed.
ADJUSTMENTSE764ADJUSTMENT OF CLUTCH PEDALPLAYCorrect play between the piston rod ofthe pedal and piston of the main cylinderis not adjustable – it is adjusted by themanufacturer. Mutual positions of thepiston rod and piston rod eye (1) so thatwhen the piston rod is fully extendedfrom the cylinder, the play between thepedal and upper stop screw (2) is 0.1-0.2mm. Then position of the piston rodshould be secured against the eye usingthe nut (3). After adjustment checkwhether the dust cover of the cylinder isnot deformed and reposition it if necessary.E765BLEEDING OF CLUTCH HYDRAULICCIRCUITCarry of bleeding using the same procedureas bleeding of the rear brake system.The bleeding screw of the hydrauliccircuit for disengagement of the clutch isinstalled on the disengagement cylinderof the clutch (1).The expansion tank that is commonfor both the brake and clutchcircuits shall be refilled with newfluid only.Brake fluid in the entire brake system includinghydraulic circuit for disengagementof the clutch shall be replaced aftertwo years of operation.ENGINE TRAVEL CLUTCHADJUSTMENTThe travel clutch is designed in suchmanner that no adjustment is requiredduring the entire service life of clutchplate lining. Full wear of the plate becomesevident by clutch slipping.176
ADJUSTMENTSE766ADJUSTMENT OF HITCH FORSINGLE-AXLE TRAILERS1. Lift the hydraulic arms to their upper(transport) position with selected positionregulation (P)2. Screw the nuts on the adjustable pullrods to the guide tube without anyplay.3. Further tighten the nuts by 3.5 turns.4. Check free tilting of the supportinghooks.5. By repeated lowering and lifting of thehydraulic arms to their transport positionverify free run of the engine atidle speed; the safety valve of the hydraulicpump shall not be activated.6. Then lower slightly the arms.G767ADJUSTMENT OF BOWDEN CABLEThe hitch is in transport position. TheBowden cable shall be stretched so thatthere is no play on the control lever inthe cabin. In case that it is stretched insufficiently,adjust it using the set screw(1). After completion of the adjustmentlock the set screw by the lock nut (2).177
ADJUSTMENTSCALIBRATION OF TRAVEL SPEED OFDIGITAL DASHBOARDDashboard is calibrated after the assemblyin production plant.Do the repeated calibration:− After significant wear of tyres− When assembling new tyres− When replacing the dashboardCALIBRATION PROCEDURE− On an appropriate area, mark a trackof 100 m length− Inflate the tyres of the tractor to theprescribed pressure, see tables of thisOperator´s Manual− Start the engineE769 E770 E771− Locate the tractor at the beginning ofthe hundred-metre track− Press the (A) and (B) buttons simultaneously.Keep the buttons pressed for7 sec. There will be an acoustic signaland in “c-n-t” inscription starts flashingon the display.− Release both buttons (A) and (B), “cn-t”inscription stops flashing− Start the tractor in a balanced speed of10 km.h -1− After travelling the whole distance of100 m, stop the tractor on a markedend of the track (see fig. E769)− Press (B) button.− If calibration has been completed withouterrors, there will be acoustic signaland “Pulse” inscription will appear onthe display− After 2 sec, calibration value will appearon the display.− After another 2 sec, the calibration isautomatically completed, dashboard iscalibrated and ready for operation.178
