Volvo cars have excellent 5 pot diesels. Why no tractor truck or industrial 5pots.
I guess because they are a ‘hybrid’ you don’t get the full the advantages of one or the other, so neither the better balance/smoothness of a six nor the shortness/economy or cost/weight/manufacturing benefits of the fours.Just seams weird no modern 5 pots in the mix.Best of both worlds i would have thought a 5 pot
Tried a kubota 150 hp and it was good, Engine didn't stall at all compared to my Deutz ( but that's not saying a lot my 6 cyl Deutz stalls for fun)We bought a 4 cylinder Valtra 5 years ago, to replace a 6 cylinder NH. It is just as powerful, and the engine hangs on well. Yes, we have a big weight on the front linkage for ploughing etc, but for lighter jobs you have a handy compact tractor.
The last two tractors that we have bought have been 150 HP Kubotas. That 4 cylinder 6.1 litre engine is a beast, and torque is very low down on revs.
My grandad had 4 and owned a countless amount of them before he retired I wish he kept oneOne of the best looking tractors ever made
Shush youOh oh.
Deutz used to make a great one fitted in poclain 75’sWhy is there no 5 pot engines
I believe MAN used to have 5 cylinder trucks into the late 90's but I may be wrong.......Volvo cars have excellent 5 pot diesels. Why no tractor truck or industrial 5pots.
Fiat 90 90 was a 5cyl,strange they never continued with it as it used to go well,same engine as the 110 90 with I cylinder less.Why is there no 5 pot engines
We have a kubota m7151 coming on demo and pricing a case pumax 140 (6cyl) both weighing in around 6.5 tonSame conversation 17 years ago on FWI when I was looking for a 105ish tractor for ploughing, drilling, fert, haulage and spraying. 110 was about as big as 4cylinder would go.
Consensus was 4cyl won't keep up with 6. Kept 6506 Deere 430nm@1300rpm and bought 4cyl Valtra. Bought it on the figures 530nm @ 1150rpm. Tractor pulls 5 furrows and a press where as the 6 cylinder Deere won't lift the plough
It's not hard to read the specs and interpreter them and if unsure ask on here to further cloud you vision.
However have bought 6cylinder 155 Case since then which interestingly is the same physical size as a 4cylinder Kubota.
But what you feel suits your situation and don't worry what others think.

Hence why many have balance weights running on shafts to damp out the vibration.Deutz DX90 was a 5 cylinder engine, I have two Silky smooth.
I was told once by an experienced engineer that 4 cylinder configuration is the worst possible from a balancing point of view - 3,5 and 6 cylinder engines have far more natural balance than 4 cylinder ones.
