Had a hydraulic top link for 3 years. The one minor disappointment has always been the range of motion for the boxblade. Not the quantity of degrees, but placement in the arc. Forward rotation is more than is useful. Rearward rotation is not as much as I would prefer. Mild enough issue I never spent any time or effort trying to improve it, partly because the boxblade is the only implement I have that is impacted at all.
Was walking by the boxblade a couple days ago and, for the first time in the five years I’ve had it, noticed the toplink structure for the hitch has optional mounting holes. The bolts were installed in the holes that put the toplink furthest from the tractor (the empty holes on the left in the pics). Moved them to the holes that put the toplink about 3” closer to the tractor.
Now it doesn’t tilt forward quite as much, but still plenty far enough, and it tilts back further which makes the rear facing blade more useful. Felt kind of dumb for not noticing the adjustable hitch feature a long time ago, but it was a happy little discovery.
Have used it once since. Just a few minutes leveling a spot for a small above ground pool. It was a nice improvement.
