High horse power tractors , pto hp

[Case856xl]

Anyone have figures?
JD RX is 620 JP but only 350 pto?
Case is 620 and 550 pto
Fendt 1050, can’t find figures

All three are man enough for the Hay bob

I am really curious to know what you would need such high hp through a tractor PTO for? I would have thought for that sort of power level an independant/stationary engine would be the usual route. I also would assume that it would need a different setup... 2000rpm shaft or a bigger stub and everything. It looks like some big tractors have 1300rpm shafts already... which I wasn't aware of until now.

Just 1 of the many uses...

Can’t understand why they don’t advertise the hp at pto shaft like they did Years ago
What use to you is hp of a bare engine on a bench

This could be @Cab-over Pete new side line when there is no lime spreading,instead of tar painting roofs

High hp PTO work, big potato bed tillers, forestry mulchers, stone grinders and chippers like the above. Also big mowing setups and big powerharrows.

Yet another stipulation imposed by the EU.
All tractors HP have to be quoted using the same standardised measurement ECE 120R or equivalent ISO which is a bench test so you can knock anywhere from 5-10% off advertised HP to get your shaft out put .

Have a look at Nebraska tractor tests, they have test results for Fendt 1050 its rebadged as a Challenger 1050

Claas 960 is 445hp tractor and 440hp at the pto.

 

[ollie989898]

Listen to this.

 

[holywell farmer]

Listen to this.

That's spuds on a huge scale

don't get all hung up on hp figures it's torque you need. you want a nice flat torque curve all the way and you will out perform the competition. the simple way to explane is say 200hp/200tq tractor hit a wall and stoped dead a 200hp 500tq tractor hit the same wall and took it with it.

Claas 960 is 445hp tractor and 440hp at the pto.

If it’s 440hp at the shaft it’s a dam sight more than 445hp at the fly wheel.

If it’s 440hp at the shaft it’s a dam sight more than 445hp at the fly wheel.

Not if you have a straight through shaft and no fancy hydraulic clutch packs giving multiple speed shifting

CLAAS tractors loose very little up through the transmission. The 900 axions and XERION loose the lease.
