My neighbor is on 5 acres and has a BX. He mostly uses it to mow with a mid mount mower and he does have an FEL.
Rough guess is that behind the house he has 1-2 acres in thick woods. 1-2 acres that are cleared including his house. And another acre or so that is wooded by cleaned up and park like. He could drive the BX in this front woods to mow if he wants. He just had it cleaned up.
To take care of the drive way you will need a box blade and or a blade. I maintain our 700ish foot of drive and 2000ish feet of gravel road with the box blade. A blade would be nice to pull some gravel back into the road but the box has worked just fine. The box blade is far more usable for me than just the blade.
One attachment I wish I had bought sooner was pallet forks for the FEL. So danged useful. Not can I move pallets of the truck. I can load brush/limbs. The forks carry far more than my 4n1 bucket. Also carrying lumber for projects is nice. The pallet forks are on the FEL as much as the bucket.
Chippers are expensive. And they require a tractor with the HP to use them. I thought we would need a
chipper but in the end if its 4 inches are larger its firewood. Even little limbs I pile up as fire starter which we need since we heat with wood. Chippers are also alot of work. This is something with one acre of woods you might not need.
We bought a DR Mower brush cutter. It can cut a 2 .5 inch sapling just like the MX 6 rotary cutter. I can't get the mower and tractor in most of our woods but I can get the DR in to clean things up. The tractor cannot go into the septic field so the DR does the mowing. The DR does have a 42 inch finish mower, snow blower and generator attachments. It is a walk behind and the brush cutter will give you a workout. I think with the finish mower it would be easier to use. The DR ain't cheap though.
