Grizzly has been put to work.

It's not everything that I wanted it to be, but it is doing the job.

My wife thought maybe I was avoiding the work and welding instead

A few more shots

KG7IL, this machine looks like it works and has no engine shaker either to vibrate it,
This is what I like about TBN, someone tries something and proves it out for everyone else to benefit from,
Please let me (us all) know whether you will make modification or this is it, because I'm going to build one just like yours, without the 5HP engine which I originally intended doing and all the work to install it.
Thanks, nice quick & easy and it works...

That's a great idea. I recently was looking at the screener being advertised on here for around 3 grand (I can't think of the name????) You have something very similar and cost next to nothing, might be a good project someday for me

So, how well does it work? What did you put your spacing at? I was thinking of using some heavy duty rebar for the screening rods.

I don't think I have major changes to make.
This is based more on that it is working and I don't want to sink any money into the project.

I used angle iron spaced about 1 3/4 I still plan on the smaller screen that lays on top. My brother in law has the material. just a matter of time.

I think rebar could be made to work. Just allow for a greater than 45 degree angle to clear occasionally.

My slotted verticals hold the chain that adjusts the angle. Lifting the high end increases the angle. I can do this with the bucket while working.


I used cheap 1 inch square tube to hold the verticles while welding. It's still there and I use it to lift and move the rig.
Sure it bends a bit but were are talking tractors and rocks. the bucket slides up the grizzly and rig hangs well for moving.
I keep it low (real low) if traveling much of a distance.



I think that it works very good for my purpose. Sod sucks and hangs up the material. But once it's out of the way, it clears well.
If I do get sod hanging up, I either scrape the grizzly with the bucket, or toss some of them by hand.

If I chop the sod into smaller pieces with the bucket, I don't have as much as a problem.

What doesn't show well in the picture is that I have 2 sheets of OSB, faced with plywood, backed by a front lip frame to use as a backstop for the bucket clearing the rocks. I did not have this when I first tried it and went right back up to the shop and fixed this.

A separator and backstop is a must.

I'll post more. Once the chill leaves the air, I am going to get back out there today.

Looks like it is doing a fantastic job! :thumbsup::thumbsup:

Yes, it's definitely doing the job. I have abused it quite a bit already, and all the weld's continue to hold.

My (2) BIL's and I discussed some changes we might make based on some free stuff I might get from them

I definitely need to build my planned screens to reduce the pass-thru size.
Everythings was done with my WeldPak 125HD FluxCore. No new welder yet!

You must have done a very good job on it:thumbsup:. If you run into something that your machine is to small for, you could always run up here, and I'll buzz it together for you.

Which side are you loading it from. I figured with my B3200, I can't go much higher then 5.5 feet. If you are loading from the backside (sloped side), any issues with Rocks hitting the tractor as they roll down.

While I am churning new earth, I load from the high side. After a long run, and the rocks build up. I will clear the low side and redump some material. Bigger rocks come rolling down and YES, they do hit the tractor. I am ok with some dings and dents.
You may wish to avoid this side.

You will need to design yours to accept your 'dump-over-height' It is probably higher than you think. You can go just under the level bottom of your bucket. AT 45 degrees, the grill falls away quickly and allows your bucket to empty at 45 degrees also.

I have used it enough to determine a couple of design change. I'll try to post pics.
1. Stronger Top Bar. This was originally to hold it square while welding and I left it. It works great as a carry bar, but it's not up to the task. I also use it to shake the unit to clear sod and hung-up rocks.

2. Better lips to retain the OSB side boards. Right now they slide in and are held in place by friction. I have to re-install the same boards after they vibrate loose.

3. No need for angled feet to slide the unit, I just pick it up.

4. Add on screen to reduce pass size. Now that I have done about 30 yards, I think I have too many 1.5" rocks I still think multiple passes will be easier than trying to reduce it in one pass.
