Just an FYI to the OP. I have a 9000# winch on my tilt bed trailer. It runs on a separate trailer mounted battery for the short pulls I use it for such as winching a rolling vehicle onto the trailer. A rolling load doesn't draw the amps that dragging or skidding a load would. My truck alternator is 150 amp. I have a 10 gauge charge wire from the truck to the trailer which charges the trailer battery when towing. It is protected by a 30A auto reset breaker. My truck battery, alternator, and charge wire alone are not capable of running this winch without that extra battery on the trailer.
My tractor has an 85A alternator and a small battery. It may power a small 2K winch but not a 9K.
I know all about the electrical stuff. I'm a retired EE and have installed and used winches. I have just not put one on a tractor before.
Here's a pic of the truck showing the winch installed in the front bumper.

and here's a pic of the dual battery setup I made for it. Yes, I gold plated the solid copper buss bars so they would not turn green.
