Getting access to bolts.

I can see how you been trying to get the first bolt out are you tired or what?

 

Judging by the shadow from the sun the swivel should work on 4 of them . The other two are tighter and hard to tell.

 

I would normally just take stuff off like that with hand wrenches, like the breaker bar. If they are seized or stripped I would be right on the torch.
If you showed up at my place and asked: How many 20 dollar bills it would cost to cut the heads off those bolts and not get into anything else it would be one. You would be gone in 5 minutes. If plastic air lines and such are a concern it would be more.

 

take a grinder and cut a notch in the ramp if your pitching them

 

Old school it with a long handle ratchet.

 

That’s not going to cut those bolts. It may help a little with breaking them free.
You need oxygen/acetylene for cutting.

 

That torch will barely heat things up

Attached, smallest torch that ll do anything. And its not going to cut anything either

You have to get the tanks filled. Some claim to have trouble finding a place to fill them.
Depending on how much you may need it for future work,it’s probably cheaper to have someone burn them out.
