Fendt going 200hp 4pot?

[Speedstar]

Aircraft will continue to run on liquid fuels for some time yet. Fortunately they can run on biofuels no problem. There is also a great deal of oil left underground.

Rolls-Royce are not going to develope any more liquid fuel engines for planes so it may wel be sooner than you think

The well established Trent series of engines will take many decades to supersede. However, they are certainly continuing to develop the Trent and have two shaft, three shaft and UltraFan versions yet to be unleashed on the industry.
They are probably starting to develop electric engines but that is not an option for large long range aircraft any time soon and certainly not until solid state very high storage to weight ratio and fire resistant batteries are developed. These may well take a couple of decades to mature enough to be suitable replacements and will probably have to revert to driving propellors.

MF guy saying Sisu guys wondering why MF still want 6 cylinder engines below 200hp.

For older farmer/drivers?

 

[Drillman]

So its not feasible for a number of jobs.

Perfectly feasable, just start off with a full charge of leccy, and use the genny to extend the range, by time battery is flat the machine will have done a days work anyway so not really an issue. Or that’s how I see it.

That is how the current hybrid London busses work - small diesel running at peak efficiency building up a buffer of power stored in batteries to use as required.

I still say it be easy to run a leccy tractor, what are most front linkages used for? Yep to carry a weight block, now batteries are heavy so carry battery pack instead, dead easy to swap out as needed.

and remember there’s no need for the engine, cooling system or massive fuel tank so with a bit of a redesign there be plenty room for batteries

 

[Magnus Oyke]

in years to a 50hp engine will drive a generator to power a 200+hp tractor

run that by me again

The 500hp Fendt 1050 would need a battery weighing 50 tonnes to do a 10 hour shift at full load using current battery technology

 

[Magnus Oyke]

Chaps, the output per litre is still lower on this tractor than it is on the ~400hp "rowcrop tractors"

Tech moves at a frightening pace, personally I think from a power point of view the tech will filter up rather than down,

look at the 4 V 6 cyl debate, not long ago 100hp was about the 4 cyl ceiling now it’s double that!

There's going to need to be a huge break through in battery technology to get the energy density of diesel, never mind the recharging time and logistics. My tractors and combine come home every night, but I'll wager most don't. How are you going to recharge your machine in a field, miles from home. I've left combines 30 miles from a tarmac road in the USA, how are you supposed to get power to one of those when if you shut the lights off at nigh you can't see another artificial light as far as you can see in every direction?

I’ve said this many times before, when was the last time someone’s cordless drill ram flat and had to wait to recharge it?

you don’t you just swap the battery

I have a draw full of teal, cordless tools, they're great. But, if I'm going a lot of drilling or grinding, a corded drill is better, the 5 amp batteries go flat faster than I can charge them on a 115mm grinder and they're over 60 quid each now.

run that by me again

The tractor is powered by the generator not 50 tons of batteries

as said the tech will filter up so a Fendt 1050 probably not relavant for the time been if ever,

but think of the simplicity of the design, wheel motor at each corner eliminating complex drive trains, 4 wheel steer and the cab in the middle for a better ride for the operator, obviously as time goes on it won’t need a driver for certain jobs so some units could just about do away with the cab,then as they don’t need a driver that needs to go home, sleep, eat etc the machine could run 24/7 and could be smaller, so battery size wouldn’t be an issue. And as stuff gets smaller it gets lighter so less cultivation etc needed so less power required etc……

just one man with a pickup swapping battery packs out on several remote units as needed.

it’s the future and will happen so may as well go along with it

A diesel generator I doubt whether America is going for zero carbon and abandoning diesel or petrol engines for such applications in the foreseeable future.

 

[AnyOldName]

The idea of a tractor 'running in' is nonsense, the operator just gets used to it.

Engine and transmissions definitely have a breaking in period where the internal friction losses drop off dramatically, before settling to a very slow drop off rate for the rest of their working life (the latter phase is generally referred to as stabilized). Before dyno testing for anything related to performance or efficiency, we always have to put them through a period of high load testing to break them in, after that we run a daily test point to monitor friction levels, which is factored into any efficiency calculations. Plotting a graph of regular friction measurements is also a great way of monitoring the mechanical health of any engine or transmission during test work.

Break in for an engine is anything between 10 & 25 dyno hours (which are generally a lot harder than real world hours).

 

[thorpe]

So am I after spending the day getting my base station working again.

was that babestation?

 

[thorpe]

That is underpowered for the size and weight of tractor for road work.

There is a new range of Sisu engines under development which is of advanced design [well it would be wouldn’t it]. It may be that this will be introduced on Fendt brand tractors first. It is meant to have a very significantly lower noise level which is road vehicle drive-by noise compliant and class leading fuel consumption and performance characteristics. All the usual PR bullcrap which may or may not reflect some kind of reality. We shall see in the fullness of time.

if you have put a few £mill into a engine your not going to say it's crap, are you?

Hey, I'm running a sisu

Comparing mowing the same field of grass that's yielding the same weight of dry matter, taking the same time to cover the acres, with the same mower hooked on

Or the same field being ploughed, to the same depth, with the same plough

Or the same power harrow

Or the same grass harrow

Or the same bale wrapper

Or an identical journey hauling the same weight of straw, with the same trailer

I'm not trying to "claim" anything. I know for a fact how much more fuel the sisu uses

Actual work done, year, after year, after year

The same gearbox?
The same hydraulic pump?
I have run both as well, and the Sisu here is between 5% & 10% heavier on diesel than the previous 6160.4 on the same work, but the M420 was 30% worse than the 6160.4 on all jobs, it was an alcoholic. The vastly superior working revs range of the Sisu make up for it's poorer fuel use.
