I-Beam Box Blade

Wow brother! That is one substantial piece of Iron. I will not be grading gravel but more like leveling a surface for a greenhouse, trails in the wood, ect. The sides are not so important to me as are the attachment points. My tractor has draft control so I have some down force in addition to the weight of the beam.

To all who use one: How critical is it to attach an expendable cutting edge, how would you do it and what angle would you use?

Ford's Draft Control doesn't put downforce on your 3pt. It only controls a specific height, the best it can. It requires the attachment to "bury" itself and then it keeps it from doing so beyond the tractor's capability to pull said attachment.

Actually, I know of no tractor that has 3pt which applies downforce?? Maybe someone can enlighten me.

Some older tractors have down force. Some also that started life as a fast hitch and got converted. On those there is a selector on the valve to choose SA or DA mode. Aalso a pin that can be pulled to allow gravity down only. Those are a must for non ground engaging stuff like a bushhog.

Belarus tractors I believe also have down pressure as well as some modern larger tractors.

While it's rare, down pressure 3ph tractors do exist

Good stuff. I've never saw or heard of one. Thanks for the education LD1.

I'm with Richard. I knew that some old Internationals had down pressure, but nothing else about them. And I thought that only "yellow" and "power tan" tractors had it now. I love me some edumacation in the morning! :thumbsup:

There are a few out there. My JCB has down force.

Yeah, it seems there are commercial or construction types that have it. Would be cool to have the choice built into a tractor wouldn't it!!!

Forget I ever said anything about draft control.

Thanks for not hijacking the thread so useful info about box blade fabrication can commence.

A tractor.
A welding rig.
A dream of a box blade yet to be fabricated.
A can of Ford blue paint maybe used to paint a box blade yet to be fabricated.
