I am so glad you posted that as a new topic so others won't have to look under toolboxes to find where I wondered off topic. /w3tcompact/icons/smile.gif
My Kubota dealer demonstrated one to me last week. It had both top and tilt links.
Yes, the top link just replaces your present top link and plugs into your existing SCV valves. You then move the lever and the box blade (or whatever) just does all the right things without you taking your life in your hands climbing off the tractor, getting between the tractor and the implement, turning the adjustments, and then hopping back on. Yes, I know there are some people who have long arms and are strong enough to do that from the seat. Wish I were one of them. /w3tcompact/icons/smile.gif
The only thing I forgot to ask was how strong it is. With the rear blade, it takes a lot of force to pick up 600 pounds setting about 5 ft behind the tractor. He charged me $300 and that includes cutting the hoses and putting on the quick connect ends. It will probably never pay for itself but it will speed up a lot of tasks that never get done quite right because of the effort to re-adjust the top link every time it really needs to be adjusted. Just work a box blade on a 20 foot long stretch of gravel driveway and you will adjust the top link every time you go from grading forward to backward.
Someone really familiar with cylinders can surely do this better and cheaper as you will have to weld to both ends, but there are companies that specialize in making these things. As soon as mine comes in, I will let you know who the manufacturere is.
Now Mark, will have to come up with a way to re-adjust the top link with his hydro pedal. /w3tcompact/icons/wink.gif
