Since this resurfaced, I thought I would describe my dad's (or mine, my brother owned the David Brown) 1956 Ford 800. It is the NAA's bigger (42 horse) newer brother. No power steering, 2 stage clutch, live hydraulics. It is amazing that the 2 stage clutch system that came into being in the mid '50's is still prevalent today. It is reflex for me on my Kubota to stomp on the clutch to stop the pto, not flick the little hydraulic lever.
The transmission was unique, only one I have ever heard of/seen that shifted vertically. Standard 6 pos. H pattern on end. Half way down forward/back for 1-2, full up 3-R, full down 4-5. 3rd was a nice working gear, so you effectively had a shuttle shift.
We put a HEAVY DUTY loader on it, really needed about 1/2 again more tractor for the loader but it worked. I was carrying a 12' oak gate on chains (welded on center mounted chain hook) when BOTH front tires exploded on me, looked original, were probably not rated for a loader, especially a 1970's massive thing. I thought I'd been shot. As jinman said, horsing that steering wheel around was a job, 'specially for a 12 yr old. Setting still it could not be done (by my Dad either). Wasn't a problem so long as you didn't have a load in the bucket, simply put the bucket down, the front of the tractor would instantly go up, turn the wheels to where you want, and back up with the loader. I guess that is sorta hydraulic steering. /w3tcompact/icons/smile.gif The loader is gone now, as we are out of the hog raising business (was primarily for cleaning the barn), so the tractor is back to being a respectable useful tractor, rather than the behemoth it was.
Dad did a major engine overhaul a few years ago, crank bearings were making noise that they were going to egress a connecting rod. Yes, oversized crank bearings were readily available, as is pretty much everything. Very simple engine.
It is a sweet, nimble little tractor. So low slung that it will slide off a hill long before falling over. I am actually much more comfortable on hills with it than I would be with my Kubota. Those saddle tractors are just STABLE! I fully expect to inherit that tractor when Dad is done with it in 30-40 yrs. Not that I am necessarily looking forward to it, as he will have to no longer be with us to give up his little Ford.
I have wonderful childhood memories of that tractor. First thing I ever learned to drive, at 5 yrs old.
As has been said above, I could go on, but . . .
