Yes they are right handed but they're torqued to 285-325 foot pounds. If you're able to run the drive system use it to loosen the bolts. With wrench on the hex run the drive motor in the correct direction to loosen it.

Would a "cheater" bar/pipe work to break it loose?

They are tight and should also be installed with loctite, they will be horrible to crack if done correctly. I use a spanner and a piece of angle iron with 6' of water pipe on it. I use that to get leverage. For this method you need to un-do the hydraulic lines to the drive motor though.
As already said, if the drive system works, put the spanner on and use the steering levers to remove the bolt. Just be careful to not get caught in the chain!
