Hi folks; I am a relatively new backhoe owner, picking up a 2011 JD 310J 4x4 via auction. I am looking to add a hydraulic thumb to it. The unit is already plumbed with auxiliary hydraulic and I presently only have one bucket (24"). I'm curious if anyone has suggestions/leads/pointers to a recommended thumb for the unit. Love this forum, thus far!! Thanks, Chris
Right off the bat, you may have an aux 1 way valve and setup for running a hammer. The thumb would require a 2 way.
How am I able to tell? One port vs 2-ports?
