What's the most versatile piece of equipment? Which model should I get?

[Tenwheeler]

The tiller is a troy built and the tractor is a Cub . Its a bit overkill, the loader and excavator are semi retired from work projects . The old equipment isnt worth a lot and I seem to have a hard time parting with equipment anyhow.The old mare might be offended at being confused for a cow .

Thanks for the reply. Apologies to the mare and the Troy Built. Wife gave me a card for an eye appointment she made for me. Said you have got to have new glasses. That's my story and I am sticking to it. However I did pass my CDL physical with scratched glasses and all.
Still believe that he just needs a decent tractor. Rent bigger equipment for a job if needed. If he has no experience it could be cheaper to just hire an experienced operator with equipment for that job. Maybe he can find a neighbor like you and they can help each other out.
