    Tractor 3 point hydraulic grapple claw

    Made this to attach to my boom pole for picking up logs, brush, and other junk. This speeds up the process since I don’t have to get off the tractor and hookup via chain to what I want to haul off. My material cost was about $400.

    Materials listing:
    1 – 36”x20”x3/8 air or propane tank $50
    8’ – 1.5”x0.243 DOM tubing for hinge and pin bushings. $52
    10’ – 1” solid steel bar for hinge pins and hydraulic mount pins $40
    ~80# scrap drop 3/8” plate steel $50
    3- Heavy duty D rings $15
    10’ – 5/16 chain $15
    2 – Chain clevis $5
    2 – 2x8 hydraulic cylinders $120
    2- 3/8 x 2’ hydraulic hose $12
    2- 3/8 hydraulic T fittings $10
    2- 10’ ” hydraulic hoses $20

    I started by making the support box on top of the air tank. I then made the tower that the hydraulic rams attach to. I made my hydraulic cylinder mounting plates and attached them to the tank. I then cut the top of the tank (approx. 1.5” wide) to mount the hinges. I inserted the hinge pins in the DOM tubing in order to make sure they properly line up. I then welded the hinges in place. Next I torch cut the teeth in the side and bottom of the tank and where it was completely split in 3 pieces (top support box, left and right claw). Plumbed up the hydraulic hoses and attached to boom pole.

    So far it is working as planned. I do need to replace one hydraulic hose with a longer one as when the claw if fully opened, it is stretching the lower hose.

    Clever reuse of the propane tank and overall fabrication. Thanks for sharing.

    Thanks for the feedback. Hope someone else finds this useful to maybe build their own or make one better.

    This got a heavy workout yesterday. Nasty winds blew down large trees and took out power for 100,000+. Neighbors tree fell across my driveway. Six cuts with the chainsaw to section the tree and then all tractor work. Never had to get off the tractor to remove the tree to the burn pile. Back up and clamp on and haul it away.
    Why buy it if you can build it.

    This is another great honor. There are many homemade tools that are great. I love getting inspiration from others on here.

    Not sure what the next tool will be... So many ideas but too short on time to make them all.
    Why buy it if you can build it.

    I REALLY like stuff like this sort of stuff - bonus points for using the hyd system on the old JD.
    Thanks for documenting and especially for sharing.

    Cheers,
    Tyler
