I thought about adapting one of those top links as well. I think they are more of a snubber with some sort of internal cushion effect. But you might have something there......

The unit I have has only one cylinder. There is no manual or parts breakdown that I can find and the company tells me the item is too new and there isn't a manual for it yet. I didn't think that was smart given the litigious nature of our society.... But it is what it is.

If it's new it should have came with a manual. Why would anyone produce something and ship it with no manual........yet. That makes no sense.

If it has trip springs then skip the pillow valve. Even my double cylinder set up didn't have the pillow valve- I'm adding it though.
So with that said you will need 2 hoses and the ball valve. The cylinder will have either have SAE o-ring style fittings or NPT and the valve will likely be NPT.
I will make no comments about a fireman helping "LE". I'm sure you have already tried shooting it!! Lol

Agreed. I assumed there would be a manual that came with it. I just got off the phone with them. They're going to research and see if there is a manual and email it if they find one.
Time to go outside and start moving snow.....

On a side note, I was saddened to find out later in my career that firemen refer to cops as blue canaries. Perhaps you are aware of the story behind this?
Anyway, I found a small blue glass canary in an antique store some years later and it now sits proudly on my mantel as a reminder..... Said with a smile on my face of course so no hard feelings. ;p)

Why would I need two hoses? Couldn't I use the hoses that are already on the angle cylinder? I could simply remove the quick disconnects on the ends and attach the hoses to each side of the ball valve correct? Or am I missing something?

They are an air (or nitrogen) over hydraulic. Similar to a car shock with an external adjustment.
Fill the cylinder full of oil, couple your hoses together, see if you can move the plow. If you can, you still have air in the system. It aint gonna happen. Once that cylinder is full of oil, you CANNOT compress that cylinder. Where do you suppose the oil that is being displaced by the rod will go?
If you retract the cylinder fully, and only fill the rod side with oil leaving the cylinder partially full of air, Then things will work as you want as air is compressable. But would result in a very spongy plow that wont hold an angle. And what would be the point of even putting oil in the cylinder. Just use it like an air cylinder.
Some plows, have a manual place to pin and hold an angle. If yours has that, it would be a whole lot easier just to take the cylinder off and use it like a manual plow. Or just get the right hydraulics and be done.
Still a good idea to us the CRV. The springs protect the cutting edge, but its limited in its effectiveness if you catch something with a leading edge. And does nothing it whatever you hit is above the ~6-8" height that the plow pivots (trips) around. Like if you were to clip the edge of a solid snow bank, or even craze a tree along side your drive.
And he needs more than two hoses and a ball valve, because what he want wont work.

OP was asking for a temporary solution to "lock" the blade with the cylinder. Blocking the flow of fluid from one side of the piston to the other would do that - no? The hope would be a hose would fail before the cylinder, if the blade impacted something, which is why just capping the cylinder wasn't recommended.
The hoses you have are fine. Didn't realize you already had hoses.
Of course having the pillow valve is best. The easiest way to set this up is with two equal sized cylinders which allows the "relief" to flow from one cylinder to the other.
The plumbing would be more complex with one cylinder as you would need a way to add and subtract fluid from the cylinder side of the control valve. OP states he has one cylinder though.
I think (hope) we all understand this setup isn't ideal. I'm assuming OP needs or wants to move some snow ASAP and understands the risks.
