I recently painted a 55H plow. What do I have to do to get the paint to harden? Its so soft you can scratch it off with your fingernail, what do I need to do?

Don't know the answer at all... But what kinda paint did you use... I painted a motorcycle gas tank with engine enamel when I was a kid.... Sure was proud of it and went to show t off a few days after painting. Something got against it and just shoved the paint off......
THaving spent a good bit of time around a biddues body shop, I can tell you tere are so many types of paints out there nowdays it's impossible to give a real answer to your problem. That said I've seen paint where the hardner wasn't mixed in, where the wrong hardner was used, where the right hardner was used but it was 'out of date', etc, etc. In each case the paint never got hard like it was supposed to. In the instance of the 'old' hardener, the paint actually glazed over but stayed soft enough underneath the glaze that the first drive down the road, at night, filled an otherwise beatutiful paint job full of every flying critter imaginable. Looked like a really big, pretty fly trap.........
Beyond that, your guess as to what happened will be as good as anyone elses without knowing every component used, how it was mixed, the product used under it, etc, etc, etc, etc, and how all of it should have worked to turn out a good paint job that obviously got off track somewhere and didn't do as it should.

Trim your fingernails? It will harden up soon enough.
The paint probably needs to dry more thoroughly - and that can take close to a month - maybe more.
Modern two part paints have hardners that greatly speed up the process,but most consumer grade paints - including all those in spray cans - take a good 30 days.
They of course don't tell you this on the can or you'd never buy it.
If you can smell the paint at all on the part - it's still giving off whatever it is it has to give off to be "dry".

would a hot air gun do any good????
Heat gun works great if you want to peel it all off and try again.
There are so many variables to painting, it's impossible to know what went wrong, or if something is wrong in the first place!!!
First off, it takes more than an hour for paint to dry. In fact it takes up to 30 days for most spray paints to reach full hardness. Give it a few days in full sun to help "bake" it.
Second off, if you didn't prepare the surface the paint may never stick. The surface needs to be clean, dry, free of grease. Paint holds better if you can rough up the surface some with sandpaper or a scotch-brite pad. Painting over old paint is a crap shoot. The new paint may reactivate the old paint and cause it to come loose.

What kind of paint did you use? Acrylic enamel with a hardener will dry regardless of circumstances. Non hardened enamel could take several days.
However, there are so many variables in paints, it's hard to tell what the problem is, if there actually is one.
I was once involved with a new leased Ford E100 cargo van. The original paint from the factory never hardened. If you spilled gasoline by the filler and wiped it off with a rag, you got paint on the rag. Ford covered it under warranty and a brand new van, with less than 1,000 miles, was scraped down to bare metal and repainted.
At first the Ford District Manager just couldn't figure out what happened to "that one van". Then in conversation he let it slip about all the other vans that had the same problem. So apparently even the Ford factory painted a whole bunch of vans with a batch of bad paint.
In your situation, I'd give it a week or so and see what happens.

The original paint on 1960's Deere equipment would do the same thing. When we bought new equipment to the farm the machine shed could smell of new paint for several months. The larger paint runs would stay soft and pliable for many months too.
Sun and wind will halp the paint finish drying faster.

I used Van Sickle enamel without any hardener, but I painted it roughly four months ago and it has been sitting outside since. I first gave it a coat of rustoleum primer. I had planned to give it another coat and I got hardener this time, so I will paint it again and see how things go..
