The only reason you have "down" pressure is because your lift arms are basically pushed completely upward as far as possible. Your top link is also longer than what most people use. A boxblade may sit back about 30" (not 4-5 feet as your bale/pallet carrier) and if tried in your situation, the boxblade would almost be vertical and unuseable.jeffinsgf said:No down pressure? What's this?
Notice that my rear tires are about 3 inches off the ground. It will do that with the box blade while you're working if you push it a little too far.

Darn, I better go out there and tell the 5 acres that I have graded with the boxblade and the toplink that it can't be graded right 'cause my boxblade was unusable.
In my opinion, the biggest reason to get a hydraulic top link is because you can extend it farther than a threaded top link, and you can tweak the angle of a box blade so that it bites in and presses down. I can assure you, when the boxblade lifts the rear tires off the ground, it is not vertical -- now usable could be debated. I never put that much pressure on trying to accomplish anything. Usually it was "geeing" when I should have been "hawing".

Interesting picture, Jeff.
Not only because of the top link that seems to have monster extension, but also because I am curious what you have bolted to the top of your ROPS?

That's the bracket to mount a TuffTop canopy.
I guess I didn't realize that my top link had "monster" extension. It is the one sold by TBN member and advertiser, Carter & Carter. I sort of thought the extra extension was part of the reason for buying one. I know I'll never be without it.

jeffinsgf, got a laugh from your post!
There is a difference between down pressure and power tilt, though.
What you have is power tilt. With a long implement, it will lift the tractor, as you show. But, true down pressure would supply a downward force to the lift arms. A TNT setup does not accomplish that. Only a change to the rocker shaft design would do that, or auxilliary rams pushing down on the lift arms.
The effective difference is that you can't push the blade down without also changing the angle of the blade. picky picky picky...
