Fendt going 200hp 4pot?

[Cowabunga]

Having been at Boeing & RR , is enough for me

You do realise that electric planes will have to be propellor driven as in the 1950’s.

Long term your buggered then unless you go back to filling evostick and glue fix up with oats on a morning

in your opinion. Outside of your little bubble in the real world there are many areas where your scenario won’t work

Has a diesel electric train got a 20 Ton battery no

No, because they don’t run on batteries. They are either diesel/electric with the diesel driving a generator which drives electric motors, or they run on overhead cables supplying electricity, or third rails in some cases. Or they have both systems, such as the new Hitachi, Alstrom and Bombardier models. I think GWR use Hitachi intercity trains which were meant to be all electric but the line into Wales has yet to be electrified so they use diesel/electric for a good proportion of the journey.

Has a diesel electric train got a 20 Ton battery no

Using that analogy, combined with your previous observations about takeoff power versus cruising power:

Without a battery, when the electric motors on the wings are at take off power, then the fuel burning turbine generator needs to have at least the same power output.

With a battery, then during takeoff the electric motors can pull energy from both the turbine/generator and the battery. This allows a smaller turbine to be used, plus the option of plug in charging before takeoff. The battery will need to be sufficiently large enough to store enough energy, and have a high enough discharge rate to supply the required power.

I’d need to do a bunch of calculations to estimate the battery weight, but given that a current Tesla battery weighs 500+ kg, I‘d imagine that the Dreamliner (250 Tonne take off weight) would need a hefty battery.

One problem I can see with a single turbine generator is the lack of redundancy, all large passenger carrying planes need to have at least 2 power plants, with the ability to fly on only one of them.

Prey tell then how they gain propulsion? By definition they will not use a jet of combusted hot gas. Perhaps they use sky-hooks or only fly downhill?

 

[Farma Parma]

Iv had sisu engines and they were quite thirsty, i also drove a mf 6s180 recently and it wouldnt of pull your cap off, struggling to get to 50k on a bit of a hill. Is that not the same engine

totally new engine series & its 5litre
Massey uses previous gen 4.9litre & once you get them going there no slouch.

 

[Farma Parma]

So is your complaint lack of power from the SISU or too much fuel consumption?

my 6S-180 is good on the juice so far.

 

[Spud]

I've owned both deutz and valtra(sisu) 4pot 150hp, both tier 4.

I've been accurately recording fuel use for near 2 decades (how else does anyone know the actual cost of making a bale, ploughing a field, hauling home straw, etc etc etc?)

Whatever the job, be it gently pulling a roller, or chapping like the hammers of hell driving a power harrow, the sisu generally uses at least 20% more fuel per hour than the deutz

SISU area worked per hour on some jobs (mowing, harrowing) is slightly greater, but nothing like enough to offset increased consumption

Looking at the cost per kwh link that you posted, the 5l sisu costs more to run than the equivalent deutz, so @daveydiesel1 is absolutely correct to say that fitting sisu is a backward step for fuel economy

However, the accountants will be far happier fitting an agco engine, and to hell with whats good for their customers

All that pales into insignificance when one considers engine longevity. Isn't a Deutz engine a service item these days? They seem very disposable in some Fendt models. Reliability usually scores higher than fuel economy when you're in the thick of it.

 

[Spud]

So why would one want a 4cylinder 200hp tractor.

Back in the 80's a TW35 was a very big tractor, one that could pull nearly anything. They were well known for being able to put the power to the ground. This was primarily because they were heavy for the hp, so the engine lugged down rather than wheelslip occuring.
A higher power to weight ratio results in more power than grip, which is why comparatively light tractors like (for example) Fendt 724 are often seen laden down with wheel weights and big blocks up front, in order to put the power down.

You need weight to pull weight, as the saying goes. This applies to trailer work as much as draft work.

Are there lighter jobs that require 200hp? Fert spreading? Tedding and raking? I'm struggling to see the benefit of 200 over the current 4 cylinder ceiling of c.160hp

Certainly in my experience implements are more reliable where tractor hp is the limiting factor in output.

I have the 6.6 sisu in mf 7614,tier 2, 300 hrs id class it is decent on fuel. See how it goes on the disc very soon.

Engine runs nice and ticks over sweet, like a 5.9 jd.

Ant...

Not necessarily,they can spin the turbine woth electricity, id day this is how they will due to noise and aero efficiency.

It depends on what speed the aircraft is designed for, at slower speeds (up to something like Mach 0.5), I believe that turboprops are more efficient, but also a lot noisier, hence they’re used for big military transports etc. Turbofans are more efficient and quieter, so they’re used in planes like the Dreamliner.

 

[Drillman]

The 20 tonne battery, plus the weight of the diesel engine, it's fuel and generator may be a stumbling block

Not everyone needs a 500hp Fendt. I can’t think of anyone locally who has one, even the big estates

 

[Drillman]

in your opinion. Outside of your little bubble in the real world there are many areas where your scenario won’t work

Don’t worry I’ve done farming in Australia and know what is and isn’t possible

Once again only thinking in your bubble.
I think a lot of the world is going to be forced into something unrealistic for them.

changeover battery packs are a system I hope I never see. We are going to need a serious price rise in commodity sold to cover additional costs. It’s illegal here to drive oversize equipment on the road at night so this means at seeding time we will get a 9-10 hr work day in if we have to take machines back to be charged over night.

thinking about it electric cars are never seen out here. Some hybrids but no fully electric. It’s too hard to run them out of the city

Diesel Electric train do not use over head cables or get power & do not from the tracks . think what you like , some technology is not for your every dad cow man.

Power cannot be magically created either. A 50 hp engine feeding a battery and big electric motor can only do so for a very short time, especially if the big electric motor is running at or close to peak power most of the time.

There wont be commodity price rise, farmin is a form of communism where you give it your all every day to provide cheap food for people that doesnt appreciate it and thinks farmers are lower claas that holds up traffic,dirties roads,treats animals cruel, pollutes water courses etc etc. And what do we get in return? We get told what we can and cant do, we get held to ransom by deara,red tractor etc, sometimes we get a bit more than cost price and the rest of the time its a head scratchin wonderin how were gonna make it stack up. Tell me im wrong as sometimes its feels a bit communist to me
