Lights, Lights, Lights. Never enough on a tractor it seems, so I added more. This is the source of their power.
I attached a fused, heavy gauge wire to the main battery cable post on the starter (orange wire). From here on
I ran all the wires in that black wire protector stuff so it looks more factory.

I followed the factory wiring harness up behind the dash, back down, and across the transmission tunnel. I obviously
removed the cover that is normally over all this stuff. You'll notice that I picked up a ground here as well.
There was a convenient bolt holding on some sort of breather screen (or whatever it is) which I borrowed.

I followed the factory harness a bit farther under the seat before making an upward turn on the right side of the seat.

Up under some "bodywork" and follow the ROPS.

Attaching the actual lights to the ROPS took some thought. Way too much thought actually. I went through a hundred
designs in my head, involving the creation of all sorts of fancy brackets, custom fitted hanger bars, etc, etc.
In the end a simple piece of flat bar with 4 holes in it and ordinary U bolts from the hardware store solved the
problem.

I also added a rotating yellow beacon for those dark winter evenings plowing snow where I have to go on the road a bit.
This picture also shows the switch box I made. 3 single pole switches to switch power to the beacon, the front lights,
and the rear lights. The box also serves as a connection point for all the ground wires.

All the projects look really well done Brad. How many amps is your alternator? John

I don't remember offhand the exact output, but the stock 990's alternator is pretty wimpy. Running all the lights will definitely exceed it's output, but I'm not too worried. I ran the front ones for a couple of hours tonight while moving some dirt and then checked the alternator to make sure it wasn't getting too hot. It wasn't even warm. I think the worst case is that I'll drain the battery some, but I can always top it up with a charger if necessary. I put an Optima in the tractor, so it should be able to take a bit more abuse than the stock battery.

don't take offense...but you know they make square u-bolts, right? i used the 2" ones to mount my lights to my ROPS, and they fit like they were made for it... /forums/images/graemlins/cool.gif

No offense taken at all /forums/images/graemlins/smile.gif

Yes, I've seen square U bolts, but I didn't see any at the couple places I was shopping at, so I just got these. If I stumble across some, I'll replace the round ones because I agree it would look better.

Brad,

Slow down with these add-on's to your tractor! You're making the rest of us locals look bad!! /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif

Look great! Good job.

Very nice job. Much better then the two rear facing ones I did for the snow blower attachment I just bought.
Still, it will be nice to see where I'm going in reverse.

Nice 990 you got there! Gotta love them. So how many watts or amps are your lights? If they are 50 some watts and you have 4 then I should really think about getting 2 more.
