my 42" forks arrived this last week and I had the perfect job for them. I trimmed my pine trees and had a big pile, I picked them up in one load! could have never done that with my 24" forks which I got with the attachment. Project number 2 today was to remove a large bush from the front yard, I thought I would give the 42" forks a run at popping the bush, I worked for 45 minutes trying to get the roots to pop. I finally put my 24" forks on and was done in 10 minutes. I'm sure you all know this but the curling power was 10x better with the shorter forks.
I guess this supports the idea of "the right tool for the job"
