Thanks for the replies.
The advice about buying a backhoe are probably right on. Would love to have one, but probably would not use it a ton esp due to hassle of swapping it out. And will use the brushhog style mower a lot more to keep scotchbroom, black berries, saplings and grass in check.
Also will be moving and lifting logs (I work with logs) with the FEL afair bit and the more weight I can lift the better for that up a point.
I live on small acreage now, but the new place is much bigger and rougher (and I am going to try to buy the adjoining property). Will be a constant chore to knock back the grown several times a year.
And I will admit I actually have never even driven a tractor much less a brushhog. In an ideal world I would get to try in person a few sizes of tractor actually doing what I want to do, but that probably is not going to happen.
For the finish mowing where flat I have a riding lawn tractor and for steepish slopes or trails I will put a bcs 852 with a small brush hog (and a flail) into service.
Also to start with I am hiring an excavator and a tracked bobcat with a big brush hog to help me clear where the shop is going to be, and to start the war with very mature scotchbroom (some of it 9 ft tall) and blackberries that have had their way with the property for several years unbothered.
