Well then that means my 8N is grossly overloaded with just an empty bucket on the loader....which I would agree that it is absolutely overloaded

. Put more than about 200lbs in the bucket, and steering becomes virtually impossible.
Having to be an acrobatic circus clown just to get on/off around the Wagner jungle gym is a royal PITA as well. I really don't understand how Wagner, Dearborn, etc sold so many of these things back in the day...
The only reason I've kept this thing is that I can't afford anything better. Thankfully, I finally got my crane working well enough that getting the loader on/off is pretty simple, and since I really only used the loader to lift things like engines around here, I really don't need it anymore.
Though now that I'm looking at a possible full engine rebuild...it may finally be time to find some money and buy anything better....
actually... I agree... these tractors weren't really designed for payloaders... you could put a loader on them for occasional stuff...
I think where my opinion differs is when it comes to the next generation of tractors. Most think that a tractor, like a 3000 is much better suited to a loader... my opinion is that they are marginally better suited to a loader... the loaders of the 60's were better than the loaders of the 40's... but the front ends of the tractors were essentially the same, other than power steering. These tractors also didn't have the reversers of modern tractors... which meant grinding gears, often on some shifter between your legs... while also trying to work loader levers up near the steering wheel... or some halfhazard setup that ran off of the remotes... which... on a 3000 also means reaching down between your legs... Yes, these loaders often had power tilt, as opposed to the PITA trip buckets... but the cycle times to lift/tilt were abysmal... in some cases you would probably wish you could just pull a trip lever, lol.
As evidence... I point to the number of 60's and 70's vintage tractors that ended up with broken spindles when people went to round bales... get a nice, heavy, bale of baleage on a bale spear and drive it around on soft ground for a while... and you'll find out what your limiting factor is... the loader? the steering? or the tractor?
If you really, really need a loader to use like a payloader... I would roll my dice, skip past go and get a bobcat or modern tractor with MFWD, reverser and modern hydraulics.
If you don't really need a loader all the time, and don't have a lot of money... then I would go with the most economical, reliable version that you can get your hands on... which.. in some cases may be an old N that can lift the occasional motor out of a car or move a couple wheelbarrows full of firewood on hard ground. Or move your little pile of horse manure, if you have one or two horses... while also running a little finish mower to keep your grounds clean.
To me, the reason to move past an N to, say... a 641, 2000, 3000... would have more to do with implements. If you also need your occasional loader tractor to, say... run an old haybine... a baler... maybe a tiller...or maybe a larger bush hog...or a larger finish mower (I HAVE seen people put a six foot finish mower on an old N... and then wonder why it's overheating...they're only 20HP, after all) then the live PTO, ability to have remotes (although in both of my cases with a 641 and 3000... I needed to buy an aftermarket spooler to get remotes, the tractors often didn't come with them standard)... you get some more power...with a 3000 you get 8 speeds... so you could get a nice slow speed for a small tiller, etc...
I also think that the N's are perfect little "complement tractors"... for us, we have modern tractors... one with MFWD and a modern loader... our N does "N stuff" far more economically and repairably than buying some little 20HP Kubota for 25K.. or a 20HP throwaway MTD clone of a lawnmower...
