Re: I built a Mid Mount grader blade for my 140
The blade steel is only 1/8", I think, but it isn't soft, as the new ones are. Plus I think that thickness isn't really critical as it is really a sluice or gutter for moving the gravel,dirt, whatever away. The work get's done by the cutting bit and the scarifiers. here is some friction, yes, but it'll take quite awhile to wear holes in it. Don't get me wrong, thicker would be better, but it's what I had. Would've been nice if I would've had an old Gravely blade or something, more weight also.
