I don't know. You don't weld. You need this yesterday. It will likely cost over $800 to buy a pin on ssqa adapter .
I don't see a cheap way to do this.
$474 w/tax for kubota ssqa from LA504 loader with same pin-to-pin and cylinder-to-cylinder measurements. $365 w/tax for tree scoop and one hour of my labor to R&R and grease it.
