I suspect the forks discussed for a couple hundred bucks aren't worth buying, especially if you include S&H charges.
The absolute best cash-n-carry price I've ever seen is $500 for a set of new quick-tach skidloader type adjustable forks with a little brush guard and 48-inch FORGED forks. Note I shop hard to save every buck I can.
If you get welded forks you'll find out fast they're not worth having. Most times you can't stab a pallet, the forks are too thick, they bend too easily, and they're weak at the tip (like when you're pushing, dragging, or positioning a pallet).
Forged forks have a heat treatment tracking number stamped on them. Especially required if used commercially under OSHA.
Look around your area for eqpt wholesalers or contractors shucking equipment; used forks can be found.
NEVER cut or grind or weld on FORGED fork tines.
To your original question: forks are just right for managing brush piles if you're careful and don't dig trenches with them. With a little experience you can flip a brush pile ahead of you as you slowly ease along.
