I did not op for the optional Quick Attach. I studied the QA but could not come up with a reason to purchase it. While it is a nice option, I really have no need to swap out the bucket with anything. I can't even think of a reason to ever detach the FEL itself.
Several mentioned the ability to add pallet forks or a round hay bale spike, but my future plans are equestrian and you don't use the round bales for the ponies. I suppose I could use the pallet forks to move square bales, but I can just throw them in the bucket as well, or pull them on a small trailer attached to the drawbar.
As for the 4 way loader valve - not sure what I actually have on this one. My loader valve is a single lever with 4 positions - up, down, left, and right. What's left that the 4 way would do? Or is that the 4 way? /forums/images/graemlins/confused.gif
