Workmaster 75 Power Outlet

Happy1406 · Sep 10, 2020

My Workmaster 75 has this power outlet just outside of the cab under the cab access grommet. It seems as if each pair (male & female) has 12 volt power continuously.

I would assume that this. Power could be used to run a electric sprayer, or electric positioned for a snow blower. But I can’t find any information in the manual, and the local auto parts guys had no idea about this type of outlet.

Does anyone know 1) what type of connector would be used to connect to this outlet. 2) what the amp rating would be on the circuit? 3). If this circuit is switchable from within the cab.

When I contacted the dealer, he suggested that this was a European plug, and he had no further information on it.

Thanks

If you search "4 pin tractor plug" on google, you get plenty of plugs for that.

I can't help you with Amp ratings though.

Here is what I found;

The NH part number for the 7 pin connector is 361428.
The NH part number for the 4 pin connector is 81864735.

The “wiring port” where the wires are fed through on the cab is NH part number 84290317. This is the flat “D” shaped rubber piece that is removed to feed the wires through. I need to give a big shout out to Chris over on his YouTube. Channel “CenTex”. He helped locate this part number.

And to ptsg for sending me down the right path.

The 7 pin one, it's just a standard European 7 pin trailer plug. Not sure why the would put that on a US tractor though.

It's probably some DIN or Metric standard. Haven't you noticed all the metrifudge taking over the world? Can't hardly buy a hydraulic cylinder anymore without it having BSPP ports.

I think that might have something to do with not being able to walk into your local auto parts store. Fortunately you can get it through your local NH dealer.
