Snow Snow plow damaging tractor?

I am not going to debate the FEL plow thing, I had one that I build and had bad luck with it-since have gotten a frame mount setup and like it LOTS better...

BUT:
The cylinders do NOT have a relief built in. I suspect the 500 times you saw it happen was on a truck? The Meyers and Western pumps have a x-over relief valve built into them-that is where the fluid bypasses to the other cylinder providing relief.There is nothing in the cylinder to allow this.

The tractors relief valve has no effect on the cylinders since the valve is in neutral-thus blocking the work ports.

Yup. I stand corrected. The angling cylinders have relief if mounted on my trucks, but if mounted to the tractors hydraulic system would not have relief. I did not realize the WR long solenoid valve had no relief to it.
I still have no fear of plowing snow with my tractor's loader with the trip springs and float feature of the loader.

Thanks for the correction.

Just a note:

A Crossover Relief valve, or Cushion Valve can always be added to any plow, Surplus Center has this one for $65.95. Attached below is a picture of the stock JD one on my #380 snowplow.

Looks like a cheap way to add some more protection.

I wonder if mounted on my FEL crossmember behind my hydraulic couplings, that if I use my 4/1 bucket or grapple instead of plow, it will "relieve" from excess pressure and allow objects to be dropped??

Maybe they come in different relief settings.

They are completely passive until the relief pressure is reached, so your grapple or 4n1 would be unaffected. The setting is adjustable, 500-1500, or 1500-3000 depending on which one you purchased, I think Id would opt for the 1500-3000 unit myself and start low. I would like to know what pressure JD, Meyer's, Western and Curtis use but have been unable to find out (But I have not seriously perused it either-a phone call to one of the company's may yield the answer)

You would want to be in the 3000#+ range.

Obviously there is no guarantee for the tractor, while tractor damage is unlikely, the loader is the weak link.

For years I plowed snow with a tractor, then plowed for years with a truck and 10 years ago I switched to a rear mounted snow blower. I'll never go back to a plow. It's easy on the tractor and you only move the snow once, no matter how deep it is. With a plow, you're going to need chains and lots of weight in the back.

I've heard the arguement that the plow will damage the FEL, but I've never heard it come from anyone who has had it happen with a factory plow. Ive had both frame mounted and FEL mounted plows. I use a plow on my FEL now and it definitely has advantages over the frame mounted plow, expecially when you have a lot of snow. The frame mount plow does a better job on gravel where you need to adjust to the contours of a drive, but on hills and with deep snow you can get hung up. The FEL plow works fine for me, and I don't see near the force on the FEL arms as I do if someone turned the wheels slightly while loading a bucket of dirt. But having said that, yes the FEL arms are the weakest link. Work smart and don't use the plow as a battering ram and it will be fine.
Now, if I was starting with a new tractor and had more funds, then I would opt for a cab tractor and a blower. I would still get the plow for the front to use on for most snow since it is so must faster on long drives. Also, as mentioned, if you don't have a lot of room to manuever or to push snow way off to the side, then a blower is the best option even without a cab.

Do you have any picture of your tractor and plow setup?
