Henro,
"My
3PH backhoe on the B2910 Kubota has two tabs [for lack of a better word at the moment] that the ball end of the lower arm slips in between. There is a spacer that also goes in there, and then a pin is pushed through a hole in one tab, through the ball end and the spacer, and through a hole in the other tab..."
Whew, thanks for describing our setup. I'll let you know if it will work.
