This widespread of speeds within eachrange means you can changeup or down under full load asconditions vary, to optimise outputand minimise fuel consumption.Also, apart from starting the tractoror hitching an implement, there isnever any need to use the clutchpedal, so the seat can be swivelledfor field work, eliminating the effortof foot pedal operation. And witha choice of either left- or righthandcontrol, there’s real operatingflexibility to suit any applicationor driver preference.Left-hand Power ControlThe left-hand Power Control leverprovides convenient forward/reverse shuttle, powershiftchanges, range changes* andfingertip de-clutching, leaving theright hand free to operate frontand rear mounted implements.Shuttle operations are more efficienttoo, with programmable forward/reverse speeds, to reduce repetitivetasks and speed cycle times.Right-hand controlThe T-shaped gear lever ismounted in the adjustable armrest,so it’s always perfectly placed foreasy use. Simply ‘pulse’ the gearlever forwards or backwards tochange up or down throughthe six Dynashift ratios.To change range, simply pressthe range selection button asyou move the lever.Dyna-6 AutoDrive (optional)AutoDrive enables the operator toselect the engine speed at whichthe transmission will automaticallyupshift and will also downshiftautomatically according to load.The AutoDrive Controller hasthree main settings:• Manual, gives full manualcontrol with Speedmatchingswitched off.• Speedmatching, available withinboth Transport and Field sectors,provides automatic selection ofthe most appropriate Dynashiftratio after a range change hasbeen made.Gear changes can then be madeeither individually or rapidly, fromA to F range by holding the gearlever (or Power Control lever)forwards or backwards.In Transport, sequential changesalso include range changes,enabling 24 ratio changes, from1A to 4F, all at the touch of eitherthe left-hand PowerControl leveror the right-hand gear lever.• AutoDrive (see diagrams onright); in the Field sector, givesfully automatic upshifting anddownshifting of Dynashiftchanges, and in the Transportsector, gives automatedDynashift and range changes.By adjusting the control, youcan pre-select the engine speedat which upshifting takes place,between 1600 and 2200 rpm.Downshifting takes place whenengine speed falls under loadby around 20%, maintaining fullcontrol and engine braking.AutoDrive gives you total controlof the transmission, with the exactlevel of automation you require forany application, simply by turningthe AutoDrive Controller.Creeper speedsThe (optional) creeper gearboxprovides a 4.0:1 speed reduction,giving additional 12 forwardand 12 reverse creeper gearswith speeds down to around 400metres per hour at rated enginespeed.* In Autodrive transport mode0306Main Range0543210km/hAutoDrive Transport SectorAutoDrive Field Sector5Field workingrange102D1504CDAB1400 2200Engine SpeedForward/Reverse Speed4F 4F to 3C 3C to 4FHeavy Soil2D - 2CDynashift Range20EFAutomatic gear shifting302C - 2B - 2AAutomatic gear shifting40(MF 6495, 20.8R42 tyres)2A - 2F05 Dyna-6 offers 6 Dynashiftchanges in each range withmaximum speed at approx1900 rpm.06 AutoDrive - Field mode upshifts and downshiftsDyna-6 ratios.
