I am getting a branson 4820HC. Heavy for its class and lift capacity of 2700. Dealer is trying to sell me a 66 inch wr long grapple. It weighs about 670 pounds. Grapple will be for clearing brush and lifting logs for a mill I have. Too heavy? I'm struggling to decide. Dealer says I will want the heft as he sees lighter 300 to 400 lbs grapples get bent.
