Buying Advice Remotes necessary for TnT

[swiss]

Morning everyone,

I am trying to finalize the rear remotes for my order. The tractor comes with 2 SCD at the moment. Seems I need to add in pairs so for TnT do I want an additional 2 SCD or can I mix and order a FD and an SCD?

Thanks for all the input and help so far!

If you are still looking at the M7040, I think 3 rear remotes are the maximum the station levers will handle.

Remotes come in pairs to allow for the fluid to circulate. You need two pairs for a TnT but the third pair will be necessary for any other hydraulic functioning on an implement. Get as many as you can now is my advice.

There is no real advantage to the FD remotes so I'd go with SCD all around. I have one FD, which works fine, but the SCD adds a feature to the FD for very little additional cost.

Perfect that is what I needed to validate. This is for the M7040.

Thank you!

Will the SCD value also float? I would want at least one float for doing road work with a grading scraper.

Neither the FD or the SCD will "float". That is a function of the 3 PH itself.

FD has to be held in position to actuate the valve.

SCD will hold itself until the limit of the cylinder is reached. (Like on most woodsplitters.) However, it will function as a FD by not engaging the detent position.

Both the FD "Float Detent" and SCD "Self Canceling Detent" valves have detents in their forward most postion. Both valves operatate the exact same when NOT in their detent positions.

The FD will "float" when you push the lever all the way forward to the detent position. This is just like the "float" detent position of the FEL valve. When the FD valve is in the detent (float) position, fluid is NOT forced in any direction. Fluid is allowed to flow freely in either direction. An example of this is a batwing on a big mower. The float position allows the batwing to move up and down (to "flap" its wing if you will) to follow the contour of the land.

The SCD, when in the detent position, will force fluid to flow in one direction -- just as if you were holding the level forward manually. When the ram reaches its max position and the pressure builds, the valve will automatically cancel and the lever snaps back into the neutral position which in effect stops all fluid flow.

These two different types of valves operatate completely different in their detent positions. These also have nothing to do with the operation of a 3ph. If you are going to use these valves to operate hydraulics that are for use on the 3ph (the TnT is a perfect example -- which of course is what you are asking about), you will need to understand how the 3ph behaves (no down pressure, freely floats up, only lift pressure) and how the hydraulics used in conjunction with the 3ph behaves in order to achive the desired outcome(s).

Also, I don't have a TnT setup but I do have a big grading scraper and use it on my gravel drive. My 3ph lift arms have pins that can be rotated 90 degress to allow the lift arms to float. I use this "floating" position when I use my grading scraper. It works nicely.

I only have two remotes on my tractor. It came with one SCD and I added one FD when I ordered it... so I have one of each.

One thing to remember, if your hydraulic cylinder comes with a check-valve, like on my CCM hydraulic top link, the float position of your valve will not do anything. The check-valve will prevent the cylinder from floating.

A much better explanation.

That's what I was asking. It looks like if you didn't have remotes you could just use a hydrolink.
