I asked Travis what the grapples weigh he said, "Weights are: 54" - 455 lbs., 60" - 472 lbs., 66" - 500 lbs., & 72" - 525 lbs. for the Construction Attachments compact grapples. The only one so far that we have a definite weight to publish is the 66" weighing 410 so you can count on ours being about 90 pounds lighter than the CA across the board." I think my bucket is 360 lbs. If I had the heavy duty bucket it would be 400 lbs. So if I went with the 72" it would be approximately 430 lbs. There is only 70 lbs difference between a 54'' and a 72'' grapple.
