New JCB TM420

Anyone heard any spec details of this? Only assumptions I can make from the photo is 4.2t lift and 26 inch wheels. Looks a fair machine.

The 320s wrecks headstocks for fun. So I hope they have beefed it up if it's 4 ton lift

Has a qfit headstock guessing thats standard as dont think pin and cone where ever designed for 4 tons
Looks a whole new swan neck dwsighn aswell
Wonder what the lift height is
Suprised they havnt gone double extension like the Schaefer

Know of a claas 4.4ton lift on pin and cone headstock!

Schaffer dropped the 9380t with double extension ages ago. Non were sold in uk and only a few in Europe. They wete too big, slow and clumsy. The smaller 9660t replaced it still with 5ton lift but single stage 5.9 metre boom, some of these have sold in uk and plenty in Europe so hense jcb jumping on the band wagon.
Just need manitou to reinvent the redrock th500 now and bring out there preview 3 ton pivot they had earlier this year and will be back to where we were in 2009 with muliple choice in the pivot handler market☺

Sorry that was just an assumption on the state of some pin and cone attatchments i know of on 320's

Do u think this would match the Schaffer lift height as would make it a fair bit more usefull on straw stacking

Eventually a manufacturer has seen the light and put bigger tyres under one of these machines, all the weight can be translated into pushing power now AND if it happens to be in a field which is a bit soft it will grip rather than sinking

I think there is a market for a 6tonne unladen weight machine with 500 70 24 tyres under it, fairly sure all the 6 tonne machines have R20 tyres under them at the min

What are you doing to them?

Probably nothing other than normal use.

They fatigue, they put great bits of chunky steel at right angles to each other, and then give it the beans with some massive hydraulic forces as often their pivot geometry leaves something to be desired.

They cost save many braces, stiffeners, gussets etc out,

Then they weld it all together with some pee pot run of pigeon street welding and spray it yellow.

It's no wonder that they go back.
