Operation
NOTE: At ambient temperatures of -10°C or less, the gearshift lever and the controls may be difficult to operate for the
first minutes after the start, until the oil in the gearbox is not warm.
IMPORTANT: If the tractor is moving, a gear should always be engaged (except when changing range, gear or direc-
tion). To do so could result in the operator not having full control of the tractor and may result in personal injury.
USE OF THE GEARBOX
Xtrashift
TheXtrashiftgearboxwithelectro-hydraulicreverseshut-
tleisavailableintwoversions.
- 4synchrogeargearboxfor3ranges(Low-Normal-
High)3Powershiftrangesunderload(onlyavailable
inforwardgears)andelectro-hydraulicreverseshut-
tle:36FWD+12REV-40kph.

Shuttle and 3 Powershift ranges under load.
 Reverseshuttleunderload:Allowsthedrivingdirec-
tiontobereversedbysimplymovingthesmalllever
onthelefthandnearthesteeringwheel.Theelec-
troniccontrolunitguaranteessmoothandgradual
reversing.Forsafetyreasons,thedirectioncanonly
bereversedatspeedsoflessthan10Kph.
 TheDeclutchsystemdisengagesthemainhydraulic
clutchbymeansofthebuttonontheactualgearshift
lever.Withthisbuttonthedrivercanchangemechan-
icalgearswithoutusingtheclutchpedal.
 Theclutchpedalisonlyusedforverysmallmove-
mentsofthetractor,e.g.tohitchorunhitchanimple-
ment,andforgreatersafety,whensuddenstopsare
madeorobstaclesareencountered.

 Theoperatorcanshiftfromarangetoanotherwith-
outusingtheclutchpedal,underloadandwhilethe
tractorismoving,simplydepressingthebuttonon

Potentiometer to regulate the engagement speed
of electro-hydraulic clutches (5) - All models
Thepotentiometercontrolsthesolenoidvalvesofelectro-
hydraulicclutchesengagingforwardgears,underdrive,
overdrive,reversegears.
Inparticular,itcanprogressively change the clutch en-
gagementtime,sothatthetractorresponseisselected
accordingtotheconditionofitsuse.
Suchavariationisdisplayedontheinstrumentclusterby
anumberfrom0to100:
0-Slowresponse.
100-Quickresponse.
