My significant other drives it fine. Main thing is to know what she might want to use it for next and leave it configured right - she doesn't like taking mower on and off, nor loader on and off. So if I know she might mow, I take loader off when I park it. If I think she might move dirt, I put loader on and take mower off.
I tried to convince Mum to get one, she has an old TEA Ferguson, and a mini-excavator, and a SxS and ride on. And one machine could replace most of that, with much easier use. Importantly she has no FEL, although the mini-ex fills some of that need she'd be way better with a FEL to lift and carry. She uses the transport tray on the TEA for that, but it's not really the same.
It's super nice having a machine that's reasonably capable, but doesn't wreck everything it drives past (unless your son is driving it).
