Yes, but may just have to go slower in tall, thick stuff. Also may have to have some additional counter weight on the front end if lifting with 3 ph.

I wouldn't.
I owned an 850, and if I remember right it was only 25/26 HP (22 PTO HP)
Mine would struggle in thick, deep grass with a 5' cutter. It handled a 6' belly mower fine.

If it doesn’t have a loader you’ll probably want some suitcase weights on the front with either a 5’ or 6’ although the light front end does make it steer easy if it doesn’t have power steering.
