Matt, here's the one we use. It's made in NE, but I can't remember name right now-but I'll get it.

Anyway-we use it on a 16r DMI NH3 bar, which is pretty heavy. The cylinder works very well. We change pitch of bar on-the-go for varying soil conditions to change deptch or control the covering action. It also aids in "hooking up" tanks. We've used it for 3 seasons now.

OK-Kelly jogged my memory re. name. GNUSE MFG! That's it. Here's their link:

The only downside is it that it creeps. We've had it on 3 different late-model tractors & it creeps. This guy mfg a model with a check valve that will NOT creep, but it's more $$. If I were doing it again, I'd get the model w/the check valve. The creeping is not unbearable...but if you go for 30 minutes & forget about it, you'll change pitch significantly.
