power plug in for the back of the m5 ?

carvel minne farmer · Apr 10, 2018

evening all working on my m5 to get it ready for the summer. got it all stipped down, to repair and replace leaking hoses etc. there was no power plug on the back. so got looking in the manual at the electrical drawing and it shows hot line from the amp meter to a 20 amp fuse, from there to a plugin on the back (says 2 pin) ground wire coming out to chassie ground. now to my question? is there a standard tractor plug in that the implements use? ie balers etc. should I put the original 2 pin plug back or is there a better option that would upgrade the tractor for todays world?

That little plug was standard between many tractors "back in the day", reproductions are available at some of the tractor restoration sites, but I don't think this one carries them, not sure. They are pricey.

If you are restoring it and want it to be original you need one, I can't think of any other reasons for having one nowadays.

You could go with a 5 or 7-pin trailer receptacle like the modern tractors use, and just use the power and ground pins, and bring other pins into play for lighting, and turn signals as needed, if you modernize it that much, IMHO.

I'm surprised you aren't familiar with the old two prong outlet. Our AC and JD tractors had them. NH used that type for the electric speed control on their bale thrower. I had replaced the original on my 4020 to power scales on a little home made grain cart. I now have a modern gravity box with lights and scales which I use for fertilizer. As Bob suggests, I updated the outlets on some of my antique tractors in case I needed to use one on the fertilizer wagon. I only have the power and ground hooked up on the newer 7 round pin receptacle. So, I think I have the replacement, original type, two pin receptacle I took off the 4020 around here somewhere. You're welcome to it, but I imagine you can get whatever you need out there cheaper than paying freight from the east coast.

On our tractors that plug was used to power the scale on the feed grinder mixer and feeder wagon but originally was used for a warning light
on an implement it was a common plug in the 50's and 60's before the now standard 7 pin Plug I know Steiner has them part number ABC395 and
the matching plug is ABC1868 this site may have them and I'm sure other places do too.

good morning bob, I am familiar with the old 2 prong plug, but what i'm asking is what do I install now to be compatible with the more modern eguipment. the old style 2 prong was standard back in 1961 when this tractor was built, but what is the standard today? I looked at the tractors at agco last week and the new tractors had large 7 pin plugs like you see on a semi.

There's 2 common plugs on most generic monitors now, the 3 pin D shaped one, or the 3 pin twist lock collar "AMP" series 3 style.
John Deere have their own style of 3 prong power plug and sell adapter cords.

Someone has installed a household 120 v plug in my tractor, lots of neighbours I've seen the same thing, just be careful you don't let
someone plug your monitor into AC power.

thank you ken, I think I will go with a standard 4 pin trailer plug then, have 1 set of pins live all the time (power and ground and 1 set on a switch on the dash). then build pig tails to match what ever implement I'm pulling, buy 2 or 3 male ends to plug in. from the replys i'm getting there really isn't a standard plug any more? each manufacturer do's their own thing. thanks again guys
