Box Scraper

I've never had an issue. That looks like a brittle weld on a quick hitch. I've never used a quick hitch. I don't see how the hydraulics would cause anymore or less damage then a solid top link. Maybe someone else is seeing something I'm not though.

Probably because it's from harbor freight....

But no, never had an issue. If you extend the top link all the way like that, the lower arms should raise up as well since they float.

Catman8 - the only way I cold see that being CAUSED by a hydraulic TNT would be if your top link was able to extend way too far for the geometry of your 3 Pt hitch: so you'd tip the attachment or quick hitch plate all the way back, almost horizontal, then push even further, to the point where your top link is out further than your lower arms plus the length of the implement. I've never seen a top link that can extend that far. Even then, it should just stop and the relief valve lets go. The break shown in that picture had to be either a poor weld or abuse. I suspect a poor weld, since the type of abuse needed to rip a good weld of that size apart woudl have damaged other parts of the tractor as well.

I saw a different quick 3 point hitch that was designed different. The top link came into the box tubing instead of cantilevered over the top like the one above. That would seem to cause less stress and the potential failures.

My recommendation would be to get a ROBB. (roll over box blade)No hydraulics needed, heavy and hold up well. There are a couple of other manufacturers as well, none currently quite as good as Eagleline though.

Mine are Gannon, but are no longer made. I have a 65" @ 800lbs and an 81" @ 980lbs.

If you get a std type box blade, plan on getting a hydraulic top link at a minimum.

Good luck with your search and final decision.

+1. I have a 72" ROBB at 710 pounds and when doing heavy work in my very dense, rocky soil, wish I had a couple hundred pounds more weight. This said, I get the jobs done but they just take longer. Concerning hydraulics, if you are not box blade experienced, a hydraulic top link with help you learn adjustments MUCH faster, along with being productive MUCH quicker due to not having to get off, on, off, on, off, on, the tractor many numerous times until you get the adjustments figured out. Another good thing about a ROBB is once you get the digging angle figured out, it usually works with only minor adjustments- if any, when changing from one function to another on the ROBB.
