How do you make a hydraulic top link float?

[rjkobbeman]

This is certainly too late for this conversation but just as a reference, our HydrauLink does have a self-adjusting feature to follow the contours of the ground.

Only problem is, HydrauLink is not a hydraulic top link.

I am new to "tractoring". Can someone explain how a chain is used with a rotary cutter to help "float" the attachment? Possibly a picture?

Not my picture, but:

I'm glad you found it... I couldn't remember where I saw it!

I started to write a reply and realized a picture is worth (more than) a thousand words.

I liked it so much I saved it! :laughing:

I need that setup for mowing the roadside; Very steep here & there!

I plan on adding a Top & Tilt (with two tilt cylinders) to my JD4300. I already have the 3rd, 4th and 5th SCVs. I would like the top link to be able to float so that when I mow with the bush hog or rear finish mower they will have a greater range of motion and follow the contours of the land better. Most top link setups have a check valve to keep the top link in the set position. Is it possible to have a check valve and still have float?

It would also like to rig the two lift cylinders so that I could operate them one at a time or in parallel. My extra SCV levers are in a neat row on the right fender so I could just work two at a time to move both lift cylinders at a time but I would like to be able to do it with one lever.
Thanks in advance for your help,

It is possible to solve the float problem with a simple 2 position solenoid valve.....the key is that float need to be connected to tank or a return line, because of the volume differential from the cylinder piston rod....

You use a chain as a top link. This will allow the tail to rise independently of the front of the cutter. My carry all/forks are made this way to allow easier pick ups and drops.
I've never used a rotary cutter so maybe someone can comment on whether this is a reasonably safe thing do.

Answering posts like this is tricky because I don't want to get into a debate or argument. It's counterproductive and definately not my intent. However, I must disagree. Hydraulics are defined as follows:

hy·drau·lic   adjective
1. operated by, moved by, or employing water or other liquids in motion.
2. operated by the pressure created by forcing water, oil, or another liquid through a comparatively narrow pipe or orifice.
3. of or pertaining to water or other liquids in motion.
4. of or pertaining to hydraulics.
5. hardening under water, as a cement.


I particularly liked the way it was worded at "How stuff works": "The basic idea behind any hydraulic system is very simple: Force that is applied at one point is transmitted to another point using an incompressible fluid."

HydrauLink uses a hydraulic cylinder, and hydraulic fluid under pressure which is moved from one point to another within the cylinder. This does NOT create pressure, but instead allows HL to hold pressure as a unique kind of top link, unlike competing designs. Take a look at our website for four different videos demonstrating how HydrauLink works.

We do not dispute that HydrauLink is different... it is! You're right. It doesn't do all the same things a standard HTL does. However, HL delivers features that no other toplink can match.

Being argumentative is not helping your business. Your splitting hairs here with the definition of a hydraulic top link. In the tractor world, a hydraulic top link is what we all think it is. A hydraulic ram that is extended and retracted via hydraulic pressure valve.

You know it.

I know it.

We all know it.

I realize you have a new product to sell. I agree it has some features (although I'm not sure they really amount to anything), but quit trying to pawn it off as a hydraulic top link.

Even by your definition, it is not a hydraulic top link. The Hydraulink does not move anything. Outside forces move the Hydraulink.
