Is there such thing as an air spanner?

[Digester Man]

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

I know all about it, done it plenty of times before but there HAS to be a better way. We have 2 of these machines which is actually over 300 bolts to change

Extension into the gap

bendy bit ?

 

[Godber]

Can you get a small extension on so the ratchet is in the clear? If that works a right angle air socket wrench will

 

[Digester Man]

Bendy socket no good, can barely get the bare socket itself on

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

Get some ole. Cub thats of school give him a locha pound

If you had something like a ratchet spanner with a worm drive at 90 degrees to the socket which could be driven by an electric drill ? There must be an equivalent used in industry.

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.

Maybe just a ratchet spanner on each side would speed things up. Still manual but the bolts aren't that long.

Would it pay you to spend an hour with a grinder notching out this area on each section- then it’ll be easy and cheap access forever for small air gun and extension?

Gas axe ? faster than undoing them ?

 

[chickens and wheat]

Im with tractor dave. Notch the thing. I dont supose its driven hard so you wont weaken it

 

[Tomr10]

Gas axe ? faster than undoing them ?

Rest of the bolt will still be in there

 

[chickens and wheat]

Or something like this. With shortest socket you can find

Get a wobble bar extension it will undo those on the angle

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.
