710's on rear and 600's on front would do them well. Maybe even 800's in the rear and 650'

It's so last season to plough in furrow, on land is the future. :cool:
Depends on the width of local roads and field gateways and how far their hinges protrude. It also depends very much on the type of work the tractor is expected to do. Lots of contractors and farmers will have these for multiple mowers, or hauling trailers where tyre wear is substantial per hour. The economics of various tyre sizes relative to the type of work they do is something that isn’t thought about enough. Most reviews tend to major on traction on arable farms rather than on more general farm work where the practicalities may be quite different.

Fit these tractors with 800’s around here and they would need a police escort on the road, or at least a registered front escort vehicle. Even with 710’s they would take up one side of the road and a quarter of the opposite side lane when set with a ‘normal’ track width.
Would 710/85R38 tyres even be a larger circumference than 650/65R42 tyres?

You are obviously on boy’s flatland.
No hills here, so yes.

Always forget that the laws on tractor/vehicle width are stricter there. 710 with 710 duals is legal to drive here, no escort of any sort needed.

That photo next to the 7722 just shows how bloody awkward the new 8 looks. Not growing on me one bit. :depressed:

It’s not the bonnet, that’s fine I suppose but the silly cab that’s far too high and the forward angled windscreen and the set square rear fenders. Just looks like a design mess in my eyes.

they look better on 710 70 42s with the wider mudguards.

Here you only need front and rear facing lights (that also work) that are as wide as the tractor.
Here anything over 3.7 meter has to be piloted from the front. Then a front and rear at 5 or 6 meter but I never do that as no clue where to find the people to do it. Up until 5 years ago couldn’t travel at night if more than 2.5 meter. Now we can up to 4 meters as long as have a rear pilot.

ridiculous rules here that are so outdated it’s not funny. I have been fined at 2.7 meters wide 20 mins after sunset

They are 650/65R42, so much bigger than they look. What they do need is to be widened out to within an inch or two of being flush with the mudguards, which would fill them out substantially. No point leaving them at the factory setting because the bottom step sticks out at least four inches either side. All but the bottom step are attached directly to the fuel tank, which is one of the features that I noticed. This was last Thursday and these are the first two I’ve actually seen in the metal. If I was twenty years younger I’d be buying that 240hp DynaVT one.
The MF 8S are too big, too powerful and most importantly too heavy for standard 650/65r42s. They are 10 ton tractors in work, all well over 200hp and all able to take bigger tyres.

My 7490 is about the same weight if not power and has no issues with 620/70R42 tyres. I think you’ll find that for many, probably the majority of users of up to 250hp machines, especially those using their power through the PTO and for transport, that 650/65R42 are perfect for them. You and many others will be exceptions of course and should order their tractors with whatever they think will do their work most efficiently.

The 8S is significantly heavier than the 7490 and even the least powerful 8S is a good bit more powerful.
All 8S with equivalent sized equipment are over weight and over powered for standard 650/65r42s. There are other 650/65r42s available, which can take the weight and power.
If I want a trailer to draw 16 ton loads at 40km, buying a 12 ton 30k trailer would be foolish.
Buying a fine tractor like a mf 8S and putting on tyres that are not rated for the HP or weight and then blaming the tyres when they fail is not going to end well.

Plenty grip here for the infurrow 650 tyres when ploughing thats for sure.
If its too wet on the top you dont plough anyways. only one wheel compacting the softer surface every run across the field
the other one is on v firm ground say 8-9" deep. diff lock in all four wheels on the masseys eh! no issues.
