No one aware of manufacturer of narrow grapple!!. My Anbo has too wide a jaw to readily dig around the larger partially buried rocks that bounce my disc arould when foodplotting. I've been using pallet forks to grub them out, but a grapple with 2 foot wide jaws would be perfect.
Thanks for the stump bucket/grapple link. I had been on their site before, but didn't see that one. The stump bucket alone may be enough for my purposes, without the grapple component. Would save some weight. Wouldn't be able to "grab" anything though.
