I’m in the “never will come loose with a wrench now“ camp.

You may be able to grind it flat with corners but that is a lot of work, then use a smaller size wrench or socket.

There may be some tool that you can find that works by grabbing the inside of the hose fitting. Something like an “easy out” .

Good luck with it.

You might be better off getting it off the tractor and getting a machine shop to get the fitting out of the block.

Time to quit playing around and get serious. Cut ths hoses off and remove the pipes from the machine. Clamp the blocks in a bench vise and use a pipe wrench to unscrew the hose fittings. One or more may twist off. If that happens grind the fittings off flush and drill the stubs out of the blocks.

Have I ever mentioned how much I dislike taper pipe fittings?....

Its only 1000 watts so I would not have high expectations. They quote 5-40 seconds to attain 800C with the caveat that it depends on part size. DOH!

Dull cherry red is 800C. For perspective my wifes blow dryer is 1500w and induction hardening power supplies start around 5000 watts for small parts.

I would be interested in some actual temperatur test results on specific size bolt and nut assemblies. How busy are you Nick :D

Ha! Yes, the unit will turn bolts cherry red. I've also used it to bend steel rods up to 1/2" for fabrication.
The larger the metal, the longer it takes.
The longer it takes, the warmer this induction heater gets and eventually will shut down until cooled.
Consider a larger, more powerful unit if yer gonna do crazy large metal.

I've never had an issue with bolts up to 14mm (never tried anything larger).
The main issue I've found is when the bolt is so brittle, it just falls apart.

Busy? What me???

I just bought one recently as I have wanted one for a while. I am the brother with a lift and tools and a couple of my brothers come by when they have a tough job. We have struggled with some tight fasteners in tight places and I have arthritis in my hands so my strength in them isn't what it used to be. Hoping this is one more tool to help this 71 yo to keep wrenching.
A couple times we have bent a wrench to get in an area. I am thinking it might be handy to heat that for bending too.

I really like my induction heater for stuff like this I don't want to put a torch to.
^^^^^ This.

Applying a flame to that fitting will ignite the fluid. Cut the hose off flush, use an inductive heater on the steel and when it's good and hot apply a 6 point socket to the brass fitting, using a wrench to hold the steel side.

You guys have inspired me to try again tomorrow though. Unfortunately with the corners now being rounded off, do you guys think hammering on an undersized socket will still get it loose? W applying heat and all.
Now you need a nut extractor. They have spiral teeth that bite into the fitting when rotated counter-clockwise. Look for the style that has a 3/8" or 1/2" square drive like a socket rather than just an external hex to fit a wrench. It's much easier to keep things square when applying the torque via a socket wrench extension than via a wrench hanging off the side.

It's going to be fun getting those hard lines off but this is about your only option at this point.

I've had success with these. Lowes has them, or used to, Irwin brand.

Got it guys. To say I appreciate the suggestions would be an understatement! Took the hard lines off the machine and secured it with some clamps onto my table. Grinded some corners onto the rounded nut and heated with a heat gun I forgot i had. Using the two-wrench-one-hand method did the trick. Glad I checked with yall before forking over $700 to the mechanic
