My friend, you have got to be THE first person to agree with me on that one.:QUOTE]
See, I know what I'm talking about even when I don't know what I'm talking about. Side link would be more important, from what I've experienced. To be able to change the grade from what the tires are on seems like half the job. Top-link just adjusts the 'bite' agressiveness (boxblade), that seems to only need two adjustments, one to start and another to finish, but the angle is in need of changing often.
In some situation you are correct. In others, it is a life (time) saver. For me, it was a cool novelty when I first got it. After I used it more and more, it became priceless.
My 3ph is Cat-II. My cutter is a Cat-I/Cat-II type. I don't know if the Cat matters, but when I hook it up, the tail will not raise very high. For transport (especially through ditches) I have to raise the tail up higher with adjustments to the top link. (Simply raising the hitch does not get the job done.) That is eaiser said than done with a regular top link. The hydraulic top link (the REAL kind, not the Hydraulink thingy) makes my work a breese. Trus me, this isn't laziness... it is simply productivity.
Raising the tail wheel of a 1k lbs cutter is not a fun job. The hydraulic top link really is a valuable tool.
In additon to cutting, grading becomes a smoother, easier and better job too. Being able to adjust the top link on the fly allows you to adjust it while you are tractoring down the road.
