So last big storm and the 12' Daniels plow "A" frame broke at the angle pivot. Did the same thing last year. It has beefy looking pin but the A frame is the weak link. This time I drove the Bobcat down to the welder they had it fixed in a few hours. When I returned I asked the guy how weak of a design is it? He said pretty weak, he agreed the pin is big enough but the frame is not built to tough. They made a new bushing cut off the old end wrapped it and welded all together. Too bad it's well hidden in the plow otherwise I could get a better look at it.
Anyone else have on break there?

I had the same issues but on a western plow. Happened several times until I found the problem.I am not sure about the daniels plow but the western was built to work on a truck and not a skid loader so the solution was a pressure bypass valve that we installed on the A frame.
Due to the high breaking pressure that the skidder has on the relief,This valve reduces the pressure. I would bet it started to break when frozen piles where hit, With this valve installed it would allow the plow to let the fluid transfer from one ram to another. Simple fix under 150

Do you have a 'bonnet' over the pivot pin?

Did they rebuild the entire push beam?

You will need both of these for a permanent or long term fix.

Push beam is way, way undersized (wall size).

Bonnet will keep the push beam from pushing up from A-frame when snow builds up underneath it. THis happens especially when backdragging a lot.

It's a one ram angle system and it has a cushion valve on it.
Mark, I'm not following you with your terms?
I don't back drag very much

I'll try to get pics, but mine is left on site.

Maybe I'll even figure out how to do little arrows pointing to the trouble spots. But don't hold your breath.

 

[Jeffksf]

I will try and do the same:wink

 

[Jeffksf]

here are my pics
The first one you can see the rusted metal on th eblue a frame is the newly welded in wrap

Different than mine, but basically the same problem.

No suggestions right off hand, not sure if my welder has fixed any like that.

I am assuming your a frame is just angle iron ? Take it back to your welder and tell him to take a flat stock piece as thick as the angle, and make a triangle box with that flat stock and weld that in on the a frame. Your breaking problems will be moved to another area on the plow.. opcorn2

IMHDAO The real problem with that design is that the turntable is too small/short. All you have there is that small arc/radius and there isn't enough area to spread the load out over to keep the pressure off of the center pin.

For example look at a Fisher turntable they usually extend out a good 18-24'' depending on the plow size and model.
