Here trouble, here boy, come on trouble!
Don't do it, axles not made for it and it's little or no benefit anyway.

Have you got a folding fork so you can then roll tight to the walls ?
Contractor here has a JCB 434 and rolls tight to the walls with his.
No duals on his,750s though.
Looking for some but think there would still be a high risk of tearing the side sheets. Duals would give a bit of wriggle room
Fork when folded is a fair bit narrower than the machine folded,14' when unfolded. A scaled down version would be better for your axles than duals.
Very true,the reason my contractor upgraded to a 434 as his 416 ate diffs costing a lot of money and downtime.Will tell son. Last thing we need is to burger an axle in middle of silage
If I knew how to post a link to a firm who makes folding forks I would,hopefully someone who can will be along shortly.

Had Narrow duals on jcb 414s. Had to pump them up incredibly hard or they’d come off the rims when all the weight went on them.

Putting duals on a machine on the clamp defeats the object of what you want to achieve!

For stability they are certainly a good job and help climbing on grippy grass. Makes climbing worse on wetter slimy grass though.
For rolling walls, to get the compaction required needs full weight on the dual wheel and none on normal otherwise its just to make silo look pretty.
Full weight on the dual leads to axles, hubs, planetary gears etc.
This is my experience from Tm270 and 412 from about 12/15 years ago so things may have changed but don't think axles are a JCBs strong point.

If you’re spinning wheels then you’re undoing all the rolling from the last pass

The dropbox would worry me more than the axles, on a 320s it's not fit for clamp work without adding any extra strain.

Just get a set of stocks duals for it, any dealer should be able to sort you out. I sold a set last year to a customer and used to use a set on the TM I used to drive when on farm and they were stocks too.

I like them on so you can roll upto the edge off pit and then turn and not fall over the edge like you can with a pivot and not turn to getaway from edge
You can roll duel to edge and rear not near so keep out of danger
I fined tms and shovels do diffs and axles more because they drive between farms at speed they need trailering between jobs

How doesn’t it you put them on stuff to reduce ground pressure!
So why use them on clamp when you want compaction?
All it does is make the top of the clamp look pretty easily.

Yes you are compacting the grass But in my thinking all you are doing is getting the air out i
So if you have single wheels yes it puts more psi down but if you have a wide buckrake it carrys more weight pluss the weight off machine
If you layre the grass in say six inch to ten or less you are only squashing that layre or two so because off the weight and the extra width you are roling twice as wide so every pass you roll more air out if you drive in and out astriding your tracks you nrly roll 3mt pluss total width were as you would drive in and out four twice to cover same area so you drive over top surface a lot more getting more air out also with duels you get near walls and top off banks
A lot youse tractors on pits
A 600-650 x 38 will have a lot less preshure than a 24 30 inch rim on a loader as the foot print is longer due to the bigger rim diameter
So in my opinion more times over the grass lighter
is better than less but heavy

If you are spinning the wheels it's not rolled well enough! [emoji12]
If I was being serious though, it's the speed the grass comes vs the capacity of the clamp machine that is the factor whether duals are needed.
