Mowing What brush mower for TZ25DA?

[newholland4me]

I have a Woods finish and I need a brush hog for some of the taller areas. What should I get? I don't want to spend a ton of money and a used one would be fine too. Any ideas where to look? I am in DFW/N TX. What do I need to know when looking? (I'm a girl w/limited mechanical knowledge

Thanks for any/all help.
