4 or 6 cylinder tractors

[essexpete]

The next one is about servicing the fourth generation, which has a filter which the fifth may not have. I can't remember everything. You'll have to watch it if you are as sad as I am.

I suppose it is an early version in my wife's elderly TT quattro?

 

[sixrow]

there was and they were brilliant

yup had one

Transverse engine VW and Audi with all wheel drive use the Haldex unit just like Volvo. They have fitted the various generations of Haldex, just like everyone else who has fitted the system.
Haldex 5 is the very latest and used by Volvo, VW, Audi, Mini, was used by LR in the early Evoque and even the Discovery Sport until they changed to the GKN system with the Ingenium engine update.
If your TT was built from approximately 2008 to 2012, it likely has the Haldex4 system. 2012 onwards it will have Haldex5

Here's a list of VW group 4x4 cars that have Haldex4

• 
  Audi TT, TTS, TTRS, A3, S3
  Seat Altea
  Skoda Yeti, Superb
  VW Golf 4 Motion R32, GTi, R32
  Audi Q3, VW Passat
  VW Tiguan, Sharan
  Seat Alhambra
  VW Transporter

That’s what my father thought about the three cylinder engine in the MF35 after having a Field Marshall and Standard Fordson.

The 3 cylinder Perkins was a very special engine though,

Phew, glad you've been able to demean yourself enough to educate us all. It's really cleared up the four verses six cylinder tractor debate

I must say that the 135 is my favourite tractor of all time. Its just a pity that everything has outgrown it. I quite fancy buying a Tafe, albeit with a Simpson engine. Maybe the 35 type but maybe open to a wet brake version.

I doubt whether they are imported any longer, what with our latest emission regulations. Anyone know?

The 135 of my youth did the ploughing and everything, we also had the 3 cylinder Perkins a Leyland 245 That used to punch considerably above it's weight.

Their facebook page mentions being at Lamma...........

We have today ordered a case pumax 140, 6 potter.

With cvt?

 

[pappuller]

With cvt?

No semi p/shift 50k fl/pto but other than that a simple dairy boys tractor.

 

[Drillman]

Was the droning across the rev range or on specific jobs?

combi drilling. He just didn't look ken the sound it made after coming from a 6cyl.

What about that droning noise 6 cylinder 1594's make. You know that whining noise from behind the steering wheel?

An interesting debate really. I must admit I'm a fan of the 6 cylinder engine, much smoother running than a four cylinder, mainly due to balancing and overlap in power strokes. This overlap in power strokes also makes a difference to the amount of mass required to keep the engine turning, or the ability to handle constant load. The 6 cylinder will also generally be the more efficient in design if, compared with the same litre 4 cylinder. This is due to the fact the cylinders are smaller and getting the correct air flow requires smaller valves and in the case of turbocharging a much smaller charge of air per combustion. Alternatively, a 'large' 4 cylinder engine, the valves have to be much bigger or more of them to fill the cylinder with air fast enough. You then have to increase the size of the conrods and crank journals to take the extra force of the combustion in this bigger cylinder, with this comes weight and extra inertia that needs to be accounted for when increasing rpms, not really a problem in a low rpm application but a factor non the less. For those more technical I appreciate I haven't gone into friction losses, increased fuel delivery etc... as these are all additional factors but tried to give a very brief overview and reason behind my choice for no. of cylinders.

Cutting a long story short, for a draft or lugging application, the 6 cylinder wins hands down for me. But for yard work, a smaller, responsive 4 cylinder would make a good match mainly due to the compact dimensions with having two less cylinders.

I disagree with nearly every word in the above post apart from the obvious, which is that four cylinder engines are more compact than straight sixes

But they aren't necessarily more compact any more,CNH particularly and Deere are putting spacers in to make them the same length !

Seems manufacturers trying to get more power every year from 4cyl engine

 

[Grouse]

Don't you mean more profit

 

[Pheasant Surprise]

400 horsepower from 9 litres enough for you?

The engine is more compact. Whether the tractor as a whole is, is down to the manufacturer's design brief. Even the MF5470 is an intermediate wheelbase with an extended front axle bolster.
