Is there such thing as an air spanner?

We have a machine with over 100 blades (a Ransomes scarifier) and the access is pathetic to change them, the gap between each blade is too narrow for a socket so they have to be changed with a spanner. We do them with a ratchet spanner which is ok but still painfully slow.

Is there any other tool out there that would be as slim as a spanner but as fast as an air ratchet? Air spanner?!
 
Here’s my problem, even a 1/4” drive air ratchet won’t fit in. There’s 162 bolts to undo by hand 😭😭😭

Modify the old blades so the new one bolts on to them, sticking out enough to give you room to work and solving the issue forever

I had a similar problem accessing the knotters on a Welger. I could get a socket on with an extension bar but couldn't get sufficient leverage because other things got in the way, so got a longer bar off Ebay. Instant success!

Would that work if you cut some length off the socket with a grinder? If you manage to screw out the bolt on the left (moving the adjacent stud out and to the left), that would give you a little more room. You might be able to grind the bar down a bit without sacrificing much strength. Every little helps! Plusgas is pretty good stuff for seized bolts.

There was a tool I saw years ago, on a dealer tour of David Browns. Used for the reduction bolts, maybe made by the factory for their own use, mass production meant no time for hand tightening anyway.
