Congratulations on your new tractor!! While I don't recommend you go out and try to bring down saplings with the MMM, I know you'll be just fine taking out weeds of any size. When I first got my BX, the first spring I tackled a recently purchased field that had lain fallow for about 4 years. The weeds were chest high, and had wold rose bushes, woody brush and reeds. The BX handled them just fine, and had only 2 problems. One was that I had to fix a flat front tire from running over previously cut woody reeds (I fixed this problem by filling them with jel...actually Soft-fil from Agco) and the other thing was that I had to sharpen the blades when I was done. The 60" mower is built well enough to handle the stuff just fine. If i was going to be doing this regularly, I would recommend getting a brush hog, but I just did it ondce, and have been maintaining the cut every couple weeks. No way could I justify buying one, much less renting one. IF there are saplings, different story...go out and rent a hog, and then maintain it with your BX.
