Box Scraper Land Leveler Build

[cjcome1]

I am building a land leveler, and have made really good progress so far. Wants to ask a few questions.

1. What angle (both pitch and angle to runners) seems to work best for others on their blades?

2. Do you recommend scarifier teeth or not?

3. Can you share ideas on a rear gate/door?

I have an idea what I want to do with mine. Just looking for others recommendations.

Specs: 6-1/2 ft wide with 15 in channel by 60 in long runners. 4x4x1/4 tubing for frame. Blades are motor grader blades that will mount to a 4x4x1/2 angle.

pics or it didn't happen!

Try this again. And excuse the shop mess (not my shop lol)

It looks like it is shaping up really well.... I don't have answers to questions #1 or #3... but I would highly recommend scarifier teeth.... ours does not have them & I wish it did.... (probably will be a future modification).

make sure you provide for sacrificial skids on the bottom of that..and double thick at the front bottom corners.

I installed my 7 foot motor grader blades at a 15 degree angle,,

I will look at what it takes to add them. They aren’t cheap, but I’ve been told they are a nice to have.

What pitch did you use on the blades? Almost looks like 45 degrees, but hard to tell from the pictures you have on that thread. I’ve read most use 50 to 70 degrees. My dads grade master have a 60 degree “pitch” and the blades are just over 7 degrees to the runners/sides

I really do not know what you mean by pitch, unless you mean like the pitch of a roof on a house,,

The blades are angled 15 degrees off of 90, or 75 degrees to the side,,
as far as the angle as compared to the road surface,, that varies as compared to the height up the blade,, as the blade has a LOT of curve,,
The blades are out of a 14 foot CAT road grader,, the blades were swapped out on a new unit, and had never been used,,

So, since there is so much curve,, near the road surface,, the pitch must WAY LESS than 45 degrees,,
maybe even less than 30 degrees for the first inch of height,,

Having the cutting edge so steeply angled, may be the reason I never had a need for scarifiers,,

My best guess, I have pulled my landplane under something like 10 or 15 miles,, total,, in 4 years.
these blades have shown zero wear in that distance,, (heck, the wear has barely removed the paint from the edge,,, :laughing ,,
I am thinking about turning the unit over, and using an angle grinder to sharpen the blades even more than they are sharpened now,,,
If the blade were sharper, the unit would cut even better,,

I really thought by now, the blade would have worn away to a sharper angle,,
I am getting old, how much longer can I wait!!

The reason I installed the blade at such a low angle, I have seen motor graders operate with the blade angled that steep,,

The motor grader probably can angle the blade like that to enhance its ability to cut into the road surface,,

If you think about it, if the blade were installed at 90 degrees, it would have WAY LESS ability to cut,,
so, I think, the blade cuts more like a knife, as compared to scraping,,

Also, with the blade angled so parallel to the road, the blade is MUCH stronger,,
if the blade were angled standing up straighter, there would be a much greater chance that the blade could bend, if the landplane encountered a stump or big rock while being pulled by a 50+HP tractor,,
