Re: MT 665B
How much HP has the cat tractor?
Re: MT 665B
I guess it's not a CAT but a Challenger. That is the AGCO
brand they're selling the line of tracked tractors under.
Didn't know the wheeled tractors were sold in Europe with
challenger decals.
On their site it says 240 PTO hp and 290 engine hp.
Hope that helps.

Is that a pure challenger product? Or is it of some other
brand in the big company? Or do they sell one tractor under
a number of brands (again)? Maybe someone knows more.

Re: MT 665B
i think it's a MF with another engine

it's defenitely not a self made product
Re: MT 665B
O guys, don't make me troubles:-[!

The Challenger range MT600B basically are MF 8400 with
another motor hood. But the "SISU"-engine has another name,
it is called "Challenger Diesel", but in North America they
say "Endurance", the types are 74ETA or 84ETA ;-).

But in the European Union there are new engines fitted,
because of the new emission laws. The types 74CTA and 84CTA,
both with common-rail-direct-injection and a
four-valve-cylinder head. And with slightly more performance
than in North America: The MF 8450 has got 235 hp, the MF
8460 260 hp, the MF 8470 290 hp, at last the MF 8480 315 hp.
And now the front axle has an Quadlink-suspension, so the MF
run 50 kilometers per hour:-D.

The Challenger MT600B are fitted with a standard front axle
as standard, they run only 40 kph. But I have seen them in
Beauvais - also nice tractors:-).

Re: MT 665B
so its a mf whit cat power

a mighty combination
Re: MT 665B
no this series is not CAT power, but is SISU power. Here in
NA there will now also have to be the 74CTA and 84CTA in
them. The norm is called a little different but is
essentially the same.

Re: MT 665B
oke to bad
Re: MT 665B
Hello guys:-)!

Oh, I can see, now it will become clear what the brand
Challenger is. And where the engines come from.

@Franke: Since which month the Challenger MT600B is avaible
with the new common-rail-engines 74CTA and 84CTA? And why is
the MF 8400 and also the range MF 7400 in North America only
built with the strange Dynastep transmission, which is
basically a variable transmission, but here with 21
programmed "speeds"? I can not find a reason for it.

Greetings from Germany - Franz
Re: MT 665B
Here in North America we also have the Agco brand. To let
this brand have the honors, they made the MF into a
Dynastep. But by the end of this summer the MF will no
longer be a Dynastep but just like in Europe the DynaVT. The
Challenger is not available here in Ontario, but basically
is the same. The new engines will have to be implemented due
to new emission rules. Valtra already uses the 66CTA-4 in
their high end T series.

Re: MT 665B
don't those wheel challengers have a fendt transmission on
them? with a different looking console? i guess i've
seen/read that when i sat in the challenger on the AG Expo
in Lethbridge. i could be wrong though, can't remember it
that good;-)
Re: MT 665B
that challenger is an massey ferguson 8400, and the mf uses
the vario transmission of the fendt, so it's is a
transmission of fendt in that challenger.
Re: MT 665B
oke, that makes sense:-)
I never drove a new Massey Ferguson, maybe we wanna try a
demo in the fall this year, or spring next year, so do we
want a fendt demo too. but the outside of the cat is
