HydrauLink- a self-contained air over hydraulic top link

[HydrauLink]

... But, I believe that most any implement if dropped to the ground with the 3PH, then drive forward a foot or so, will compress the cylinder with the valve open.
There's a video on this site somewhere of an old closed loop style hydraulic top link with a valve to lock it, and it shows exactly this process... I just wish I could find it!

Thank you for the voice of support. To the concerns of a couple of you, I will work to get a simple video on how to raise the implement. It's done precisely as you described. Open the valve... lower the 3-point... roll forward about a foot and then close the valve.

Also, you'll be pleased to know that the remote for HL is being worked on now.

... Why not add a solenoid to replace the needle valve, and run a wire to the operator dash panel, but of course the price goes up.

Hmmm.... that's a different principle on which we were considering our remotes, but a good one. I'll pass it along. Thanks!

As I said earlier, I'd seen the same type of top link before, and it was from the designers of the Jiffy Hitch System.
I do think that this new design from HydrauLink is cleaner, and the introduction of air provides a needed cushion.

Watch the old Jiffy Hitch video, paying special attention to the last half where they show the operation of the hydro top link. All questions will be answered about extending and retracting the ram. So this design appears to have a proven history for the naysayers...

I wish this new venture the best of luck! We need more innovators!

So a simple piston with lets say 1/4 inch hose you could just add a valve and connect them to each other . Open the valve to adjust and then close to lock. Your simply displacing the oil form one side to the other.

Now, I'm not going to go and say you're full of crap...LOL!

I already did a little experiment dragging my boxblade with the toplink detached and it doesn't budge with respect to tilting forward. Due to this alone I'm reasonably confident that with my tractor and my boxblade cylinder retraction will not occur without applying an additional force to the attachment. I'm again speculating hear as I've not used the hydraulink, but I'd anticipate whatever method employed would be just as or more labour intensive as spinning a screw type toplink.

Yes, but the reservour mounted high allows for convenient placement of the valve, along with a small oil supply to facilitate removing all air from the system.

If retracting the cylinder is a easy as shown in Blacntans linked video I'd likely get one. I'm thinking the tractors, depicted in the video, 3pt hitch is capable of applying downward force to the arms to aid in the implement rocking forward.

Jay, This where i suggested the stack of blocks or somehthing. If you backed up them and lowered it could be retracted easily. But still inconvient ..

The product is what it is of which many would find beneficial. My only issue was the marketing which was deceiving regarding retracting the cylinder which in reality, from what I could gather so far, would not be the simple affair as depicted in the video. One would need a method of lifting the trailing edge of the implement to retract the toplink whether by hand or some mechanically advantages device. Using a boxblade to grade a road I'll adjust the scarifying and smoothing angles many times in both directions, while the screw toplink maybe a little cumbersome at least it can be used to angle the attachment forward with minimal effort. The Hydraulink from what I can can gather has no inherent mechanical means of obtaining this goal. I sure would like to try it out though to determine if I'm full of crap or not.

Like I said, until you try it you are making an assumtion.....

And as we have all been told by our parents a hundred times, when you assume..... you make an ... out of......

I would love to see one of these in action, and if it works as well as it possibly could I would pony up the cash.

Nothing in life or at least very little is free it is a fairly expensive 3 point top link, but I had an 8N with a 50 year old top link, and beleive me this would have been a lot better than that.

Even my new Bobcat's screw top link leaves a lot to desired, and to the poster who said that a screw top link can overcome the weight of an implement to raise the rear of it, he must have some really light weight implementsm or popeye arms and hands... do you eat a lot of spinich?
:laughing:

We appear to see this similarly as I also suggested something similar early in this thread by using blocks of wood under the trailer edge of the implement. Carrying around a stack of wood for blocks then positioning them to retract the cylinder would get tired very quickly and would soon be longing for the screw type toplink if that is what's required to raise the trailing edge of the implement.

For lilranch, I've mentioned that I have not used this device and am speculating on it's performance capabilities but after reading the literature, viewing the video, and performing a little test I've come to a sensible conclusion based on and for my situation only (as I've mentioned). I know full well how to read between the lines of marketing and am fully versed in the lessons of life but, regardless, it's a proven fact this device can not lift.

To quote you "Even my new Bobcat's screw top link leaves a lot to desired, and to the poster who said that a screw top link can overcome the weight of an implement to raise the rear of it, he must have some really light weight implementsm or popeye arms and hands... do you eat a lot of spinich?"


Exactly my point, the hydraulink is less capable of overcoming the weight of the implement and raising it than the screw type link is.

I apologize to all the readers and to Hydraulink, It's not my wish to belabor this point.
