I'll say a
B3200 with FEL and a Boxblade and a Rear Finish Mower will take care of those problems. When you get ready to do the finish grade on the yard then a RatchetRake will be your best implement. Also for the garden I think you'll want a tiller. If you decide to go ahead and clear the grown up acres then a 5' Rotary Mower will be of benefit. I do hope this answers all ofyour questions.
Be sure and do your own service at the first fifty hours with new motor oil and filter and change the hydro filter but not necessary to change the hydro fluid at the 50 hour service.
I know several people will tell you that a
BX2660 with a FEL, MMM, Boxblade, tiller and 4' Rotary Mower and of course the RatchetRake will do the jobs listed but your mention of needing higher ground clearance is why I suggested the B instead of the BX.
There really isn't that much money difference to pick one over the other, just mostly the ground clearance and the plastic fan on the BX with all your working in the woods.
I'd still recommend the
B3200 or
B3300.
Now the small L supporters will be giving their recommendations of how the small L will be better with the jobs you mentioned but it won't.
Good luck and I hope this has answered all of your questions that you did not mention in your post but had planned to before hitting enter or post.
I'm sure there will be more contributors in case I failed to cover some thing.
