Another project

[skyhightree1]

I decided not to buy a new soil pulverizer for 75k ok I'm exaggerating but I need another pulverizer and something to do mayb build with my son he's interested in welding and going to take it in tech next year. I have everything except bearings and springs to build it I think. My question for y'all is I have a 3 inch pipe I'd use as a roller with the spikes on it. Since I was going to use everything on hand I was going to put concrete in the pipe for added weight to bust dirt clods. I also figured if I just use cement for the weight I won't need a spring for down pressure but allow it to move up and down with land contour. I have a H beam it's 3/8" I think. I forgot too measure but the others I've seen were 1/2 inch I thought about putting cement in the frame to make it heavier. What do y'all think.

That should work as you said just need the bearings on the ends and springs to make it float. That would be a good project for your son to get some good experience. THe concrete should just make it heavier and work better.

You will probably have to do something (Weld some little flanges on the edges) to keep the set concrete in the H-beam for the long term. (And certainly, if it's actually an I-beam instead of an H.)
Even if the concrete is just on the top, it will still get loose and bounce out after awhile.

What are your thoughts on having concrete inside the round pipe as a roller? I figure it would be heavy enough to not need a spring and just follow the terrain on a piece of steel and just go up and down.

I agree I will have to weld it to where they will hold the concrete in. Do you think a 3/8" H beam is strong enough? I also planned to just weld on some half in cut flat bar as the scarifiers I am not doing all that drilling and welding and bolting its just as easy to cut off the scarifiers and flip them.

Wish these were straight

1 cu ft of concrete weighs approximately 150lbs, depending on density.
Your 3" diameter pipe filled with concrete (not including pipe weight) would contain about .05 cu ft of concrete per linear foot and in general, concrete weighs 150lbs per linear ft.

Cylinder shape.

A cylindrical shape that has a diameter of 3 inches and a depth of 1 feet has a volume of:

Volume

= 0.00139 cubic meters = 1390 cubic centimeters = 0.0018181 cubic yards = 0.049087 cubic feet (approx .05 cu ft) = 84.823 cubic inches = 0.3672 U.S. gallons = 1.39 liters * calculations accurate to 5 decimal places of precision

If I did the math right, your 3" concrete filled pipe will weigh about 7.5lbs per linear ft + whatever the empty pipe weighed.

Concrete Weight Calculator

Calculate how much concrete or a concrete structure weighs given its volume. Concrete weighs 150 lbs per cu ft or 4,050 lbs per cu yd.

Gonna use these as the scarifiers gonna cut them at a angle

Break up clods in plowed ground.?
I've never seen a soil pulverizer I guess. Pasture renovation and roller I've rented and have.
In my opinion a 3 " roller is just gonna push up dirt in front of it and not roll at all , need more like 30" to work.
I'll eat my hat when you prove me wrong sky.

I've got a 6' Gill with the double rollers. I'd be glad to take some picture (and measurements) if you need them.

I'd be inclinded to think a larger dia. pipe would work better the the 3". The spikes are what brakes up the dirt clods, and if the dia to too small you won't get enough spikes welded on to do a good job of busting the clods. There are holes drilled in the pipe and the pins are in the holes and welded in place.

I would also encourage using the spring on the second roller. It keeps the pressure on the roller and prevents it from riding up where it does less work.

Look similar to this one.

Thanks for sharing this guys! It really helped me out

 

[greybeard]

maybe they got itty bitty clods in Virginia and a 3"roller dwarfs them?

More so to break up clods for new driveways or help with new lawns breaking it up loosing the soil
This is what I'm talking about

Do you think my H beams too small?
It looks like yours is thicker and taller probably 1/2" thickness and 12" H

You should visit some time. I'll turn you lose in my scrap pile. You'd be like a pig in mud.....lol

I'll take some measurements tomorrow. I think it might be too light. I understand wanting to use materials you have around, however you will spend some time getting everything fabricated and you want a useful implement when you're finished. Just as well make something that will work for years and be satisfied with it's build.

I saw my first soil pulverizer in a guy's row of implements and didn't know what it was for. He explained how he used it when installing water pipe along a road right of way. When he had the job ready for seeding he'd use the pulverizer to level and smooth out the soil.

Build/buy a Harley Rake. Will make chicken salad out of chicken s#$&. Pulverizers all over in the bushes now that power rakes are available.
