MACHINE Settings:
WHEEL FACTOR
The ‘WHEEL FACTOR’ has been
preset at the factory to suit the particular
seeder’s drive wheel and target. The
operator should check this value when
actually seeding if a difference between the
tractor’s ground speed and the seeder’s
displayed speed exists. Wheel factor can be
affected
by
the
tyres
circumference.
Variations in ground hardness, tyre pressure
or product load in the bin may change the
wheel’s rolling circumference.
When checking the Wheel Factor
ensure that the drive wheel, left rear wheel
fitted with sensor and target, is inflated to the
correct pressure and that the tyre is in good
condition. The seeder’s bins should be half
full of product and the test performed on the
actual ground to be sown. Refer to the Wheel
Factor or Machine section of the Farmscan
operator’s manual for specific information.
To view the current wheel factor, enter
the ‘MACHINE’ screen from the ‘MENU’
screen.
The factory settings for the
‘WHEEL FACTOR’ value for the different
model air seeders are shown below when
fitted with standard tyres.
