Functional description of electronic slip control (radar)
(Optional extra)
A relatively large degree of slip by the drive wheels is physically unavoidable if optimum use of the
tractor's draft force is to be made in the field.
If, however, slip exceeds 25 - 30%, unacceptable disadvantages ensue.
In order to monitor slip, the actual travel speed is determined via a radar sensor A011 and
compared with the bevel pinion speed sensor B015 (travel speed display).
The speed signals from the radar sensor A011 and the bevel pinion speed sensor B015 are
processed in the EPC ECU A005 .
Increasing slip acts on the EPC ECU A005 in just the same way as increasing draft force.
The rear power lift rises if slip increases and therefore reduces the draft force of the mounted
implement by reducing the working depth.

Bullet-List
Slip control offers the following benefits:
●
Time and fuel inputs are reduced.
●
Tyre wear is reduced.
●
Soil impact is reduced.
●
Demands on the driver are reduced.
●
The chance of becoming stuck is avoided.

Wheel slip calculation formula (%)
Wheel slip % = (speed B015 - speed A011 ) / (speed B015) ) x 100%

Caution:
The tractor is fitted with a radar sensor. Do not look into the radar sensor's radiation
range (microwaves).
