I have a Kubota L2501 and am looking into these 2 grapples. The Falcon is 1/4' 50 grade steel and the CID is 3/8" 50 grade. Most others that I have looked at are 3/8" A36 which is a weaker steel and they are also heavier. The only thing that I can see that I'm not sure about is these don't look like they have greaseable pins.
