Couple of pictures of one I built a few years ago . Blades are just 1/2" flat steel by 6" wide . The blades have slots were they are bolted to the angle steel for mounting . I can raise one side up above the steel runner by at least 1/2" while at the same time drop the opposite side down by 1" or more , ( Never really measured it or have I set it that way , just when I have loosened all the bolts , I have noticed how much adjustment potential there is ) .
Use it to grade the 3/4" - 1.5" shale on our 800' of driveway .half the driveway is flat , then the remaining half goes up to a maximum of 14% . It works since it keeps the wash boarding down to a minimum , at least until everyone from my better half to son to neighbors fly up and down it for weeks and the wash boarding starts again . :confused2:
Actually thinking of removing the blade from the back angle , cutting the angle off and re-welding it on so the blade will have a forward tilt rather than the current back tilt . Thinking that maybe the first blade will level , then the back blade will level and compress shale back down . Well at least that is the plan anyway :thumbsup:
Pull it behind a TC30 and as you can see it is wider than the tractor . 7' wide by 8' + long . Blade height will influence how well a tractor of a given size will pull it . If I had 12" blades , Ugh , not sure my TC 30 would handle it .
Looks like You are getting there :thumbsup:
