What are these? (can't find them in manual)

I have actually used it while using my box blade. With the draft engaged, if the BB starts digging too deep, it will raise up a bit!

When you say with the draft engaged do you mean having the draft lever lowered? I accidently bumped mine down while digging post holes with auger and I noticed it dug more aggressively. Have never really understood the draft. Maybe I need to try that with BB. I'm good at digging in a little too much and having humps and holes.

The further back you pull the draft control lever, the higher it will lift up when it becomes loaded. You can adjust the sensitivity of the draft control by upper link placement.
(the three hole options where the upper link is pinned).

This is good info I never thought to ask about. I was always wondering how the draft control works and had no idea about what that lever was
