I bought the biggest 4 wheeler available (at the time) and found it is just not a tractor. Not near heavy enough to do good pulling, no end loader, really not a great choice of toolage.
A tractor is a better choice. Even a small 30-35 horse tractor is better. I ended up with a Case 31 hp diesel w 4wd, an after market end loader (Woods) and three point with PTO. A huge difference. The 4wd makes up a lot for its smaller size.
Things like a gang of disks actually have weight and cut, the 3 pt mower uses my PTO so I am not always paying for an extra motor, all the pull behind implements can be 3 pt so I don't need the extra mounting gadgets (at extra cost).
I designed and had built a front mounted grubber of sorts that helps me remove smaller stumps (and even some bigger ones, pop smaller trees, roots and all, and bust up roots and junk. Can't do that with a 4 wheeler. That itself allowed me to clear and form the land much better and quicker.
Now if I can only transform my UP MI sand / soil to Iowa and Illinois black dirt !
The 4 wheeler can do a lot, but it sure can't compare.
But. . a tractor is usually a larger investment at the beginning.
Besides that, I use a Stihl chain saw a lot, a couple heavy chains and, to help cut out root wads, a thing, like a axe or blade on the end of a heavy metal pole (very much like the ice spuds us northerners use in the winter,but much stoughter and heavier) so I chop down and not by swinging an axe. That tool, whatever it is named, is a God sent gift as well.
For spreading seed, fertilizer and lime, I use either a 4 wheeler mounted spreader or a hang over your shoulder hand spreader, depending upon access.
And a lot of sweat.
