I use a Land Pride (LP) cat 1 QH with my attachments, a Tractor Supply carryall, a LP blade, a rotary cutter and a LP tiller with my Kubota 2920.
For adjusting the toplink (manual for me), I position the QH lower arms below the attachment pins, then get off the tractor and spin the top link turn adjuster (turn buckle?) to fit the top link hook under the attachment top link pin. Then I can (while standing next to the tractor) just hit the lift control and scoop it up.
For most of my attachments, they share the same top link position on the QH, so if it's already set correctly, I don't have to get off the tractor, but just back up to the attachment and scoop it up.
If the attachment has a different scoop height for the top link versus run height for the top link, then I have to do the following (note that only my blade seems to be like this).
I go through the scoop as described above. Once I capture the blade, then I lower the blade to the ground to take the weight off the top link, and then adjust the top link turn buckle in. When it starts to take the weight and give resistance to turning, I lift it and set it back down and repeat. When done I can usually lift my blade a good 16 inches off the ground, giving me lots of clearance for the blade during transit.
I really like my QH. I think it's superior to the Pats system as I don't have to monitor or adjust the width of the lower lift arms. The advantage that I can see to the Pats system is if you have a auger. For that I have to remove my QH, but you could keep on the Pats system.
I have had to get my drive shaft extended on my rotary cutter as I often bush hog my dam and that requires me to back the rotary cutter off a flat road and down a steep hill, which requires a longer drive shaft. Either the Pats or the QH would have required the longer shaft, as they both extend the implement back about the same amount.
Hope that helps....
