Grapple vs Forks? We have both. The grapple is new and I put it to work yesterday. Things I could not do with the forks, I easily did with the grapple. Moving longer pieces longer distances was far easier with the grapple.
The ability to grab and drag things out to where you can pick it up, huge advantage.
Staying on the tractor and working the machine without having to get off, position things, cut things, etc.. saved a huge amount of time.
We went with an inexpensive grapple mostly owing to weight. We didn't want to loose all our lifting capability to a heavy duty grapple on a Compact tractor. We know not to beat it to death.
So far, I am impressed with the added capabilities that one man can accomplish. The forks would have proved challenging to move the downed stuff we moved yesterday.
