D 15 II Rear Work Light Dilema?

When i got this D 15 it had zip for Lights.

I got the head lights pieced together.

There is a mount welded to the rear of the seat with a slot that looks like it is for the work light.

On the left fender on the rear are two holes.  Forward one about 3/8 dia and rear about 1/4 diameter that are about 1 1/2 inches apart.  So there is no way a mounting bolt like on the fender would go thru there.

Do i possibly have a series one left fender?  Or is the mount (which I am missing) for the work light mount in those two small holes.  The new aftermarket work lights that I am looking at appear to have the large diameter bolt like the head lights.

need some guidance here please.  thanx

I been thinking and that is dangerous i know.  gonna use the front 1/4 hole in the fender for the carriage bolt.  Cut the mounting stud for the light down so it will fit completely under the mount by using a stop nut to fasten.  Run the wire through the existing little hole or create a new one for that.  By guess and by golly do a 1/4 hole for the stud on the rear of the mount.  i will make the adjustments to make it look right before tightening the mount down since I will probably never use it at night.  Thanks also for the pic Myron, i will use it for a guide.

My dad has a series II, 1968. His headlights are on the fenders, rear work light is mounted on left rear fender. Has a switch to turn on or off. No mounting holes in the right rear fender. Sounds like someone mounted a slow moving sign bracket on the seat, not a work light bracket. Just guessing. I will get a better look tomorrow in the light. Going off memory now.

I make the new tail light mount casting and also the head light mounts. also sell after market lights.

Sorry I HAVE to say it...

JD had those rear work lights that switched to red for road use in the very early 50's. They were way ahead of their time. Allis must've copied them...

Norm answered the telephone this am.

Thanks folks, I got the mount and light ordered.

i now have the repop mount casting and the light.

The casting mount has a round (about 1/4 inch) stud in the casting with no threads on the rear of it.

My fender has the front hole for the carriage bolt and a smaller hole behind it for what I assume would be the power wire.

Question is should i grind the stud off of the mount or bore a hole in the fender for it to drop in.  Boring the hole would be kind of by guess and by golly.

I am thinking of grinding the stud off and relying on the front carriage bolt to hold things in place.

What do you think, or what is the answer on the mounting?

Myron, wow thanks for the reply and information.

Something is wrong with my fender.  All those holes you described make total sense.

Now since I am in the dark, I am wondering if I got a fender for the series 1, I understand that they had the little running light on the fender.  That may explain why the slotted mount is on the rear of the seat.

Now I m thinking that instead of getting the drill out, next spring i could fill and repaint that left fender and put the work light on the mount on the rear of the seat.

I don't know, I will probably wind up drilling the fender.  Most likely scenario since i got the wiring harness for the series II. 

    Hey Dave,,,,the D15 II I had, did have the bracket for the rear work light on the seat assembly, but did not have any factory holes at rear of either fender. It was a 1963 model and a one owner tractor. The bracket had got bent up before I got it and took me forever to figure out how the light was bolted on,,,,,,,a member here told me how the bracket was supposed to be positioned,,and once I heated and bent it back down, the light fit like a glove,,,,
   When you gonna post some pics of yours,,,??

Allis Dave....so did Farmalls back in the 40's.

If the fender has 2 holes (1 big and one small), that is where the bullet style tail light would go.  The bigger hole for the stud and the wire goes in the smaller hole.  They were used until the Series II D15 came out.

Series I and II fenders are the same EXCEPT for the holes needed for the lights.  It's very possible that the fender got switched with a better one from a Series I before you got it.  You never know what can happen over 50 years.  Tractors can't talk either.
