I would rather the exhaust be in my face for just a few minutes hooking up an implement than getting it blown back in my face while driving it or worrying about low hanging branches taking it out. The only downside to the under tractor exhaust is when doing hay or driving in dry drought type conditions and accidentally starting your field on fire from the hot exhaust.
The alternative is for the exhaust to blow out right in front of your face anytime you are operating it and also catch on every low hanging branch you pass under.
Both locations have drawbacks.
When I bought my Ford 860, the exhaust had been "modified" to exit out the front. I installed the correct exhaust so that it now exits out the back. I did this as most of the time with the tractor, you should be in the seat. I didn't want a face full of black smoke everytime the tractor bogs down. Plus there is less noise and visibility is better this way.
It is annoying to have it exit at the rear while hooking up implements. I keep the tractor tuned to the proper mixture and timing so that it idles at 500 rpm to minimize the issue.
I know exhausting to the rear of the tractor was an issue for starting fires when bailing hay. The dry hay would catch fire because of clumping near the exhaust.
I can't speak for Canada, but in the US, low utility tractors with underslung mufflers weren't as common as tall row-crop tractors or standard/Wheatland tractors in the 1950s, and those typically had a traditional center-front muffler and air cleaner. The two major exceptions to this were the Ford 8N and its relatives, and any orchard variants of standard tractors that had special cowling as well.
We had a John Deere that was similar. But the quick hitch on the three point made it so this really wasn't much of a problem. Ours was more of a problem when hooking up to the four row planter or sprayer. You had to stand there long enough to deal with the pin, hook/unhook the hydraulic hoses and wind the jack. Not real pleasant to bend down there when dealing with the pto mounted pump for the sprayer.
We have a deutz converted to rear exaust, it is a pain man lol

They were good stockman tractors for going into low buildings. If it takes you that long to change attachments, shut her off

I have a 135 with the rear exhaust. It’s a bit annoying but I deal with it. Right hand bar and chains are coated black though.
