Rotary Cutter Rhino 172 won't lift?

[JHB141]

Hello, first post.

Running a Rhino 172 rotary cutter with a New Holland 4630 ('96) and up until now, no issues. Actually, it isn't an issue, per se, more of a puzzle. Have the mower hooked to the tractor the same way I have for the past few years, lower pins to the lift arms, top link to the top hole of the three on the mower upper connecting arms. Last two times I have used it, though, when I lift it, instead of the whole mower coming up, the arms on the mower pivot like a scissor and just adjust the front end up and down. Its hooked up exactly the same with the same pins, same top link, same everything. I have a dedicated set just for the mower because they are heavier duty than the stuff I have for my other attachments. So, my question is have I had it hooked up wrong all this time and it just now decided to start working right, or did something loosen up I'm not aware of? As a side note, this is the way the dealer set it up for me when they delivered it too.

It sounds right the hook-up I mean, a picture would go a long way on helping you>

Try adjusting your top link

AH! Ok, I was about to go outside to work on something else, I'll try the top link adjustment. Didn't think of that, but it makes sense. I'll post once I try it.

That did it! Apparently, I've been slowly making the top link a bit longer every time I hook up the 'hog, to the point it would only tilt, not lift. Put some cribbing under the rear end of the mower, shortened the link, and works exactly like it used to. Best of all, somewhere in between, it tilts AND lifts. Thanks all!
