I will definitely have a set of pallet forks, and will build a carry all of sorts that I can put on them or take off (maybe built on a pallet). I've seen "the thumb" mentioned on here lately. I think it might make a great modification to a set of 3ph pallet forks, and or a FEL. If I buy a tractor I'll get the rear remote valves and third function valve up front and be done with it, ready to expand capabilities if and when.
I believe I've decided not to consider an earth auger, even if I found a good used deal. I have some other fencing planned, and I do occasionally need to set a post for trellis wires over my garden or something, but eventually I'll have all the fencing run around my property that I could ever want and then that implement would be almost useless. I already have a 2 stroke auger that works well, and I'm in sand that's easy to dig and/or run a 2 stroke auger in.
My dad has 3 acres and I used his 6' woods finish mower there from the time I was about 10 until 18. It worked well for wide open space, but I have 0.8 acres to mow with a lot to mow around. I just don't see it being preferable to the zero turn that I already have, and is already paid for

After tilling my garden, I see great value in a tiller. Even for doing some light grading work around my property. I think I could hit it with the tiller then finish off by hand in a jiffy, or smooth it with a bucket if I wind up with a front end loader.
My daughter, wife, and I planted all of our fruits and vegetables yesterday in the new garden. We enjoyed getting out there and working in the dirt, and my daughter (6 years old) is absolutely stoked about watching the plants grow and can't wait to "eat her basil"

. She will literally pick basil straight from the plant and munch on it

I tend to meander through my thoughts, but I said that to say that I think we'll continue gardening in some capacity, so I think a tiller would be worthwhile. Even though they aren't cheap. The current measurements are about 30x 18. We may even need to add room for one more row this year.
