I use a Mowing deck Rck54p23bx with my Kubota BX2360. I found one of the mowing deck wheels laying on the ground. The pin or bolt that goes through its center had sheered off and I need a new one. I'm not finding it on the parts diagrams, tho it must be an often used part. Can anyone help me locate this? Also, do prices vary on these things? I appreciate your time. See pic.
