I was wondering if i would come off wrong commenting on the bucket design but glad im actually in good company on that. 😂
I agree modifying it will be fairly easy. If you look at old trip bucket loaders from the 50s and back it seems it was pretty common to add ‘bucket extensions’ some of which were bolted and removable. If the bucket doesn’t have the breakout force to tear them up you might consider adding some 8-18” rods to extend only the bottom, something like whats usually called ‘debris forks’. It will make breaking into old dirt/gravel piles easier, let you rake while backdragging, pick up brush piles, and depending on spacing may act more like a ‘solid bottom’ and let you carry more of anything that wont fall through it. Just an idea.
Anyway that’s a super cool tractor, with the loader, rear hitch, and dual trans its already near the top of the PK heap!! Congrats!
