What's the thoughts on Case/NH 145 4cyl vs 150hp 6 cylinder.
Case 145 vs Case 150
NH T6.175 vs NH T6.180
Mixed work load.
Thanks.

I can only speak for the case 145, absolute pocket rocket punches well above what it should for a 4cyl. Mix of ground from blowing sand to blue clay on a mixed farm so expected to feed out bales/pull a feeder wagon, 4000L trailed chafer sprayer, 2400kg fert spreader, pulls a 6m toptilth which everyone thought we were crazy to try. Only niggles from new and coming up 2 yrs is the electric spools, there’s a fault in the software somewhere and still no fix 👎

Does any1 have both? Any difference in fuel consumption? Presumably 4pot would be easier on light duties and 6pot easier on hard graft but mabe am wrong?

Judging by profi tests, the variation in efficiency and characteristics between any two 4 pot or 6 pot engines, of about the same power, can be rather more than between a typical 4 and 6 pot.

Profi did an article/test recently on a 4cyl vs 6cyl tractor. If I remember correctly the 4cyl had better fuel comsumption and the 6cyl had more grunt for draft work.

The big 4 pots tend to be about the same weight and wheelbase as the previous 6 pot models as well.
I believe the 4 pots have a spacer behind the engine to make them the same wheelbase as the 6 pots. The argument is that to be able to use that sort of power you need a certain size and weight to the tractor frame to begin with before you even add ballast. Even for roadwork there's a certain balance to a 'full size' tractor.

A friend of mine has an old style Case Maxxum 115 6 pot pre common rail and a new style 4 pot 115. The 4 pot 115 absolutely annihilates the old 6 pot on pulling power. I’ve driven quite a bit of both tractors and the 4 pot 115 is a very capable tractor which punches well above its weight. Pulls a 2300 gallon tanker a medium size Shellbourne Reynolds muck spreader and Mchale round baler and a Fusion when required. The likelihood is that the dealer has uploaded the engine management software of a model further up the range. Before anyone says anything no I can’t prove it but it’s got some serious oomph in it for what it says on the bonnet.

This has been done before.

I would ignore the number of cylinders and consider how 30 years ago 30hp per litre was typical performance from an agricultural engine.

Combine that with their poorer non constant power type torque curves compared to today’s tractors with 40hp - 50 hp per litre it’s easy to see how technology has improved.

Once was a time you could only expect to find a 110hp tractor in 6 cylinder format, you now wouldn’t dream of expecting it in anything but a four cylinder - or even in some cases now a three.

Yep mines like that, pocket rocket.

There is no replacement for displacement. A big pot four will give you serious power with a turbo and aftercooler but a straight six naturally aspirated can only do so much. Big advances in engine management in the past 30 years have pushed new boundaries to what a four pot can do.still like my six pot cat motor for pulling like a train 👍

The replacement for displacement is a turbo and higher compression

We have a 4 and a 6 cylinder similar HP but different brands
Both have there place here
4 cyl a bit light for some jobs
6 cyl a bit to heavy for some jobs
But both can do each others work if needed
4cyl better on fuel, just has a small tank so gives the impression of using a lot

I have a new style Maxxum 115,it should be better than an old 6 pot 115 cos it boosts to 140hp from new. But i agree,awesome power for what it is.
 

AHDB winding down horticulture and potatoes operations as Ministerial decision awaited

  • 251

AHDB has announced yesterday it is winding down significant activities on behalf of the horticulture and potatoes sectors.

While still awaiting a decision on the future by Ministers in England, Scotland and Wales, AHDB wants to reassure levy payers their views have been heard following recent ballots in the two sectors.

AHDB is now stopping programmes of work that could be restarted in the future by grower associations, individual growers or the supply chain. This work includes for example, export market access and promotional international trade event work, consumer marketing campaigns and market pricing and insight information. AHDB will continue to deliver limited emergency work on pests and diseases, including the Extension of Authorisation for Minor Use (EAMU)’s and some...
