rScotty - I'm glad that you decided to comment,
You'r welcome. good luck with the purchase. I sent you a private message too. Look for that.
Basically I like tractors and like helping people find one that fits. Everyone has to have a hobby....., and I still remember how excited I was to get our first tractor. BTW, my library down at the office has a small collection of shop manuals and among them are a couple of Zetor shop manuals there we can use for reference. Like most good shop manuals they are big heavy tomes about the heft of an unabridged dictionary.
As for handling an 8 foot bush hog....It depends. Doesn't it always? But an 8 footer can be a monster. That Zetor certainly has enough HP, but horse power isn't the whole picture. I think our own bush hog on the big JD is close to that size.. though it might be a six or seven footer. It's heavy built...I'll have to go check. But whatever size it is, even that one can require first gear going in thick wet hay or dense brush.
Having a live independent PTO that is clutched and engaged independently of the tractor's drive clutch can be important in heavy going or against fence lines. A live PTO is less important in the open or in dry grass.
Also more important than HP is the category and capability of the tractor's three point hitch. For an 8 foot bush hog I'd want a true Category II three point 3 pt hitch in order to handle the weight and twisting of that size bush hog. The Zetor has that. Any heavy hog over six feet will usually have a trailing wheel on a boom and it's got to handle that too. Smaller tractors have a Category 1 size 3 pt hitch and that's a bit light. The Zetor hitch is massive and will do all the lifting and stabilizing easy enough. The Zetor also has a beefy enough PTO transmission to handle the angular momentum of the large rotating parts on such a large bush hog.
IMHO, any tractor using a large bush hog should also be equipped with an internal "over-running" PTO clutch. There I don't know if the 4341 has such. I'd imagine it does, but check it out. When I get to the shop manuals I'll look too. Just in case it does not, an over-running clutch can be added to the PTO driveline. In fact, it doesn't hurt to have two.
Good luck on the tractor hunt, rScotty
