Speed Transducer for Tractor
Note the following if the speed transducer is fitted to the tractor.
The speed transducer (A) and the speed ring should be located at the
inside of the tractor’s right wheel. The sensor is an inductive type that
requires a metallic protrusion (e.g. a bolt head) passing by in order to
trigger a signal. It should be adjusted, so that the transducer is placed to
the centre of the holes in the speed ring (vertical direction).
Recommended distance between protrusion and transducer (A) is 3 to
6 mm. Check this in the entire circumference.
Correct fitting is indicated by a constant flashing of the transducer, when
the wheel is rotating.
Road Safety Kit
Connect the plug for rear lights to the tractor’s 7-pin socket and check the function of rear lights, stop lights, side lights and
direction indicators on both sides before driving.
The wiring is in accordance with ISO 1724. See the section “Technical Specifications”.

ATTENTION! Turn OFF all work lights when driving on public roads!

Power requirement is 12 V DC. Always note polarity! For proper function
of the electric equipment, the wires must have the following
