Horn on a riding mower?

Your welcome....... What's a relay?

That'd be an electronic device for people that prefer not to do more harm than good when wiring electronic items on a motorized vehicle.

Never thought of putting a horn on a riding mower, but now I can see me adding one of these when I get my country place and a tractor -

Soooo.... Like this except move the switch to the neg wire? Would that drain my battery when the mower isn't in use?

I will try to tell you how to hook up the relay? Number 86 and 85 are the coil terminals and 30 and 87 are the switch terminals. Run 86 and 30 to a fused positive + source like the battery or ignition switch. Number 87 would go to the horn terminal and the horn would mount to a good grounded place on the chassis. You will need a horn switch with two terminals. number 85 would go to one of the horn switch terminals and the other terminal would go to a good chassis ground.

So the only real difference is the switch is on the ground rather than + wire? Do I really need to go through a relay cuz the headlights don't seem to have a relay and there's only 1 fuse on the whole mower.

I really don't have a answer on that other then the relay is a heavy duty switch. Why not try it without a relay because the most it can do is burn up the points inside a cheap horn button switch and if it doesn't work out for you its no big thing to add the relay afterwords. The only difference is you would run a positive wires to the horn button. What ever way you do it make sure you install a fuse for it, very cheap insurance.

What do you think like a 10A?

I don't know how many amps a horn draws but I would think you would want to the smallest is a 20 Amp fuse.
