Mowing with an A?

I mow alot of grass every year. The big fields for now get an every third year treatment with the Super M and bushhog, and the area around my camp gets done with the lawn tractor every trip.
That still leaves alot of intermediate areas, stuff like the field road and a large area of lawn that now gets mowed with the lawn tractor but takes forever.
I'd like to find another way to mow these larger areas faster, and I'm always looking for an excuse for a new tractor.
A fellow near my farm has Farmall As that he periodically restores and sells, sometimes he even has a B. These little tractors are fairly uncommon up there, but because they don't have hydralics they're not as expensive as the Super A.
So I was wondering if I could use an A with a mower to cut my mowing time.
This isn't finish mowing, but it'd need to look better than the bushhog on my Super M can do, the big problem with the bushhog is that if I set it as low as I want this grass to be its really dragging the tractor down and working it hard.
Note also that these spaces are generally too small for the Super M to do a good job.

Seems like belly mower would be good but I'm a bit worried because its fairly rough terrain and I'm thinking it would take too much of a beating...

Any advice?

Or you could also get a hayrake and rake the first cutting, and make a small haystack. Suppose mooses would eat from a haystack?

The trouble is that it won't cut very short and it leaves all the clippings right behind. For a field road I'd prefer side discharge. I supposed I could get a rake though...
Once the mower is set really short it labors the tractor something awful, like mowing really heavy grass. 'Course my mower is beat, probably one that wasn't so thoroughly thrashed would do a better job. Next time I cut I'm going to spend some quality time sharpening the blades first.
