Clamp on Loader Bucket Skid Tractor Pallet Fork chain - eBay (item 300474179347 end time Oct-05-10 14:29:07 PDT)
These are just a couple that I found on E-bay , 1 is clamp on , other is chain around bucket I guess ? Half the price that you quoted in your first post with free shipping .
I have a set of clamp on forks although I also have a adjustable bar that slides over both forks all the way back to the bucket , thus stabilizes or ties together both forks . I have used them exactly as you described with great success . Pile brush in fields , then simply drive up to pile with forks on bucket like a forklift , scoop and run . While you may not get every twig , you do get majority if you think about how you stack your piles of debris .
Start with big items on bottom , ( So you don't have to lift them later onto top of pile ) . Stack your pile all in 1 direction , say north / south . When finished , drive up to pile from east / west , scoop and go . I have moved piles of Oak limbs , although not as heavy as my TC30 , they were nearly as large , without any problems , other than fitting between trees as I snake my way through the field . You don't need to raise it over your head , just high enough to clear ground and shove .
