TYRE INFLATION SPECIFICATIONS
Formaximumtractorperformance,alwaysadjustthetyre
pressurewithintheminimum/maximumrange,toconform
withtheactualloadonthetyres.Undernormalconditions
use the minimum pressure rating for general drawbar
work.Usethehigherpressurerating,uptothemaximum,
forheavythree-pointhitchmountedequipment.

Tyrepressurecanalsobeadjustedasrequiredtosatisfy
thefollowingrequirements.
A. Severe Service.
Tyrepressurecanbeincreased28kPa(0.27bar-4psi)
morethanthemaximumpressureshowninthecharts,
fortyresusedinsevereservice.Severeserviceincludes
the furrow tyre in regular ploughing operations, and in
hillsideoperations.
B. Tyres With Liquid Ballast.
Inflatethetyres14kPa(0.14bar-2psi)morethanthe
normal operating pressure required for your operation.
Thiswillcompensateforaerationthatoccurswhenthe
tyresareinmotion.
WARNING: A tyre can explode during infla-
tion and cause serious injury or death. Never
increase air pressure beyond 241 kPa (2.4
bar) to seat the bead on the rim. Replace a
tyre if it has a defect. Replace a wheel rim
which has cracks, wear or severe rust. Make
sure that all the air is removed from a tyre
before removing the tyre from the rim. Never
use force on an inflated or partially inflated
tyre, make sure the tyre is correctly seated
before inflating.

furtherinstructionsonsafetyreinflationprocedure,rec-
ommendedtyremaintenanceandtyre/rimrepair.
IMPORTANT: During transportation, by rail or road, tractor
tyres are inflated to higher than normal operating pres-
sures. Before using your tractor check the air pressure in
the tyres to make sure that the air pressures are correct.
