He gives honest opinions (he dislikes combo buckets) and notes you'll need a true third-function hydraulic valve. Best for buyers trying to choose between these three before purchasing.
Posted by the Kubota of Lynchburg dealership channel, so this is a sales-environment walkaround, though the presenter offers candid criticisms of the products shown.
A root grapple has a much longer floor and heavy duty reinforced sections for prying big logs, but leaves a gap that lets small debris fall out. A claw grapple has a shorter floor with less gap, clamping smaller material better.
The presenter is not a big fan. It can clamp only along three edges with no teeth, so brush or debris works its way out, though it doubles as a dozer blade and can backdrag.
Yes, you need a third function hydraulic valve. He recommends a true third function rather than a diverter valve, which he calls a pain to use.
