i want to build a dirt sifter. what or how do u decide how steep it can be? i want to be able to dump my bucket ok-and i will have to allow for my teeth sticking out from it.

the reason i want to do this is because i need clean dirt to fix lots of bad spots all over my property-and i have several stockpiled piles of dirt with lots of to big of rocks to bury at my fill places. i hate to waste my dirt. ever since i seen a fella in new finnland build one out of pretty much nothing on u-tube--my mind has been thinking and spinning. my wife keeps telling to waste this dirt and get the free dirt off my cousin, but what he wants to give has lots of rocks in it too. and now we have this dump trailer-i need this sifter.

i already have gathered up my legs for it-and i want to set springs on with a gas motor to shake it. or i suppose it could just be set up like a grizzly--:dunno:but i don't think my little tractor is gonna have enough height for the dirt and rocks to fall correctly.

how about the retired engineers helping me out a bit with the degrees of the pitch--for the dump height of my tractor. i would really appreciate this help-as i passed drafting in high school, but only by getting a D-back then. i was more interested in trucks and heavy equipmenth. ttps://www.youtube.com/watch?v=RNmBMDfpJ5E now his dumping area is backwards from the way i want to dump my dirt-but for him it works-ok:laugh: when he first built it was sliding off-but way slow-- right, so he just took his backhoe and dug the front in deeper.

there are lots of videos of dirt sifters on u-tube-and i love all of them. my boy is good with a set of plans-but lacks the vision to see things in his mind, like tractor stuff. i wanted him to build me a sleeve hitch for the 2520. he said bring me a set of plans--grr--its not his fault-really i don't think he's ever saw a sleeve hitch.

I built one using just pressure treated 2x4 and 1/2" hardware cloth. It had to be at a minimum of a 45 degree angle for the material to slide down the surface without hanging up. But if you can vibrate it, you really only need a minimal angle. I'd bet 30 degrees would be plenty and the rock would still get moved to the edge and drop off fast enough that you could work buckets through it pretty fast.

45 degrees will gravity feed it without the need to vibrate. Vibrate is easy to build if you have a motor laying around but honestly isn't necessary. I've seen a 2x6 and 2x4 gravity fed on wire mesh work very well.

All you need to do is park your machine where you want to dump the dirt and measure the height with the bucket full uncurl. Once you have that you make your screen to that height.

Remember if you get it "too short" for a full dump because you moved it elsewhere or you've cut something twice and it is still too short you can always dump some dirt in front of it to build a ramp to raise the front.

If you have a motor (electric or gas) and feel like making a shaker I wouldn't say don't. The only issue is where you use it needs additional fuel (gas, elect, generator...) whereas a gravity feed works anywhere. It will also be more complex and having a shaker will stress the structure more than one may think.

ok-thanks--i'm pretty sure if i don't use a sheet of expanded metal-the size on my rocks would go thru it. last winter i thought about buying 2 dog kennel sections off of craigslist--and laying them on top of just a frame-but it seemed all them sections that had been cheap the yr before dryed up. so i gave up on that idea. i would like it to be 60 inches wide for my bucket to fit good. so if i go that wide i'm gonna need 2 sheets as i guess it comes in 4 ft section wide. the boy said he can tach it together.

the dump trailer is dumping at 27 degrees-at least thats what i thought the boy said:unknown:i wanta put a small set of wheels on it to move it around to different dirt too. but it has to be light enough if i need to pick it by the 2520. which i think is doable. the game is on to build it now. my youngest boy is gonna be surprised this Friday if he doesn't have to work--as we are going for angle iron and sheets of expanded metal.

now tell me-am i thinking 1 inch holes to big?:munch:

If you are just using the soil for things like filling holes in the lawn and stuff, a 1" screen is probably ok. I used 1/2" because I use the screened soil for my raised garden beds and I wanted to make sure I was just getting nice loose soil.

I was thinking about getting some 1" expanded metal and using that as a "pre-screen" on mine. I'd set it up as a 2-stage screen. Whatever drops through the 1" would drop down to the 1/2". Plus, the hardware cloth takes a beating when you dump a full bucket of soil on top of it. The expanded metal would hold up to the abuse better.

well i would like to use this also just for that reason. so when u buy clean garden dirt it's sifted in 1/2 screens-huh.

what if i split the difference and go with 3/4? be good for both ideas:unknown:

Yup! 3/4" would be a perfect compromise.
