Default Hay bale knife for slicing

I would like to build a hay bale slicer for my skid steer. There are commercial ones on the market, but I would like to build my own.
For the cutting arm I can use 2x6 rectangle tubes and sandwich the cutting plate inbetween, or I've got some 4x4 tubing that I could attach the cutting plate to. The cutting arm will be at least 60" long and probably end up being 72" long.
It will have a hydraulic cylinder for moving the arm up and down.
I'm kinda stuck on what to use for the cutting edge, everything else I've pretty much got figured out and have the material already on hand .
Do you guys think that 1/4" plate steel would be enough or should I go to 1/2" plate ?
Any ideas or suggestions would be helpful and appreciated.

Totally ignorant of these things, but how much power does it take to push knife through a bale? Are you planning a blade of hardenable steel or some unknown material? How difficult to sharpen? Thinner blade should push through easier. Hope. It works for you.

This is all I found on bale cutters. Maybe this may be of some help.
We are all given many opportunities in life to keep our mouth shut.....we should take advantage of as many of those opportunities that we can.
Pray like everything depends on God, and work like everything depends on you.
In life it's important to know when to stop arguing with people and simply letting them be wrong.

Is this is the guy you're looking to make? or the one Tim KS posted?

Two lengths of bucket cutting edge would probably be the ideal blade material.

two 2x6s would end up fierce thick I think.

lots of pics here: and here

Young enough to be dangerous, old enough to know better (most of the time anyway)
