AGCO - 4355332M1 - Massey Ferguson Electric Horn

This electric horn produces an audible warning signal when the operator activates the switch in the cab. It is part of the tractor's electrical system, wired between the switch and the battery circuit. When the horn button closes the circuit, current flows through the horn's internal electromagnet, which pulls a diaphragm against a contact set; the diaphragm's rapid oscillation generates the sound. A horn that fails to sound or produces a weak tone usually indicates a corroded contact, a broken diaphragm, or a faulty ground path. This component is manufactured by AGCO to match the original assembly's mounting bracket geometry and electrical connector layout, so it installs without rewiring or bracket modification.
