8.1.1

Wheel type

The

“WHEEL TYPE” function allows programming and, thus, recalling with a single key, the parame-

ters relative to different types of wheels (such as: if they are replaced for different types of crops or if
the computer is moved from one agricultural machine to another). This function recalls a parameter, the
“WHEEL CONSTANT”, which must be entered as indicated in paragraph 8.1.2 - Wheel constant.
Up to 5 types of wheels can be programmed. These are recalled for use by the procedure descri-
bed below.
1) Scroll through the functions on the

User menu

using the

and

keys and select the

entry

“Wheel type”, followed by a number that indicates the active wheel.

2) Confirm the selection by pressing the

key: the number that indicates the wheel type will

flash on the display.
3) Change the value using the

and

keys.

4) Confirm the value set by pressing the

key.

8.1.2

Wheel Constant

As the tractor moves forward, the Bravo 13X computer receives signals from the speed sensor
installed on one of the wheels. This data is processed on the basis of a value called the

“WHEEL

CONSTANT” that must be entered manually or through the automatic insertion function.

The wheel constant set represents the value of the constant relative to the wheel
type currently selected: for example, to change the wheel constant that corresponds
to wheel type 2, you must first set the type for wheel 2 following the method shown
in paragraph

8.1.1 - Wheel type

1) Scroll through the functions on the User menu using the

and

keys and select the

entry

“WHEEL CONSTANT”, followed by the active value.

2) Confirm the selection by pressing the

key: the active setting method appears on the display.

• MANUAL SETTING

To perform the setting using this method, you manually enter the value of the constant after having
previously calculated it.
The wheel constant can be calculated using the

distance that the wheel on which the sensor

is installed travels in 10 revolutions (a value to be calculated with the tires inflated to working
pressure).

The formula for calculating the wheel constant is:

Distance traveled (m) x 10

= ——————————————————

number of magnets

Example:
- Distance traveled in 10 revolutions of the wheel 25,4 m
- Number of magnets installed: 10
The wheel constant is:

25,4 x 10

= ————————————— = 25,4

1) Select the

Manual setup

mode by scrolling the

Wheel Constant Menu

with the

and

keys;

2) Confirm the selection by pressing the

key.

3) Change the value using the

and

keys.

4) Confirm the value set by pressing the

key.
