I don't have a grapple. There are times - like after cutting down & limbing a few trees - a grapple would be really nice. However, what I've found is my "poor man's compromise"....a rock bucket. Due to it's shape/design, I can push a brush pile fairly well or I can pile up brush on it a lot more than regular bucket or pallet forks. A grapple would still work better, but the way I see it it goes like this: Grapple > rock bucket > pallet forks > standard bucket.
So that's an option. I bought mine used and is oversized for my machine. It's a standard 72" rock bucket for a skid steer. But for $600 a lot less than full blown grapple + front remote. At ~700lbs though it does eat up a lot of lift capacity. I can't overload my regular 72" bucket with dirt - if i can scoop it, the tractor will lift it. With the rock bucket being longer, heavier, & can hold more, I can take a bite to big to break out. But with just tree limbs/brush I can't overload it. Could get a pretty big pile and wrap with a cargo strap to take a long way if needed.
A single tree or big log, pallet forks are great for that. A pile, not so much. But pallet forks have the obvious advantage of moving pallets (duhhh), but you really don't realize how convenient that is until you have it. Free pallets are everywhere so just using them makes a lot of basic transport/moving "stuff" around real easy.
I rarely use my rock bucket. Nice to have when needed, but seldom used. I could see myself selling it at some point. I wouldn't part with my pallet forks.
