Using, Dismounting And Mounting Of Tyre - Agrison HP ULTRA Series Operation Manual

Front wheel toe-in is 0-10mm, the number can be measured from two inside rims. Rotating tie
rod is adjusting front axle toe-in.

2.12.1 Using of Tyre
Tyre is the main wearing part of the tractor; and attention must be paid to the using and
maintenance of the tyre, so as to possibly prolong the service life.
All the tyres have regulated load values; overburden will deform the tyre excessively, bend the
tyre side excessively and crack the tyre easily; moreover, glue will be easily separated from the
tyre body fabric and the buffer layer; the fabric layer is loosen until the tyre is broken, especially
when the tractor is running on uneven roadway or is impacted by barrier, the tyre will be broken
more easily.
The inflation pressure of the tyre must meet the regulations; both lower pressure and higher
pressure will affect the service life of the tyre. Lower pressure will deform the tyre excessively,
which will accelerate the wearing of the tread, and even quickly grind the tyre casing and cut off
the inflating valve as well as increase the running resistance at the same time. If the pressure of
the front tyre is too low, it needs more force to operate; higher inflating pressure will crack the tyre
body because of excessive stretching, accelerate the wearing of the tread, and increase machine
body vibration. The pressure of the tyre shall be properly lower when the tractor is working in farm
field; and the pressure shall be properly higher if the tractor is running for road transportation for a
long term. The tyre pressure shall be checked by barometer under normal temperature, so as to
prevent inaccurate measurement because of heat emitting of the tyre after working. Improper
driving operation will also lead the wear or damage of the tyre at an early period. Crossing barrier,
at high speed, sudden brake or quick turn shall be prevented when running. Tyre slippage shall be
avoided when the tractor is running on macadam.
Don't adhere chemical corrosive like oil, acid or alkali on the tyre when using and avoid
insolation under burning sun as much as possible, so as to prevent ageing and modification of
rubber. Regularly check whether the front wheel orientation and toe-in are right or not, so as to
prevent eccentric wear of the tyre. When the wear of the tyre figure is uneven, exchange the left
tyre and the right tyre for use.
