I have a B2601 with a LA434 , I want to buy a handle that attaches thru two holes in the back of the loader arm except I don’t have those two holes! Then I noticed on the LA435 that it has a different hinge, I drew the yellow arrow to it. Has a pear shape. Anyone know what the difference is? Obviously had a design change. I’m not a fan of drilling holes in my tractor but if I want the handle I’ll have to… the hinge pin I’m just curious about… thanks!
