A rollover scraper with minimum

[MJPetersen]

great Job Mike, do you have any sketches you could share, have to make one now to save changing time switching

Laurence

Thanks. You know I really do not have many sketches. I have one that I will scan and try to give some dimensions. I believe that mine would be adequate to 25 hp, but believe that everything could be scaled to a bit larger if you needed.

I centered my rotating pivot, but if you check posts #6, 19 you will see that rich has a Gonnon that is 40 inches wide but the pivot points are not in the center of the side plates. Probably his has a better balance and does not rotate so decisively to the ripper position. Mine rotates fine, but it may be that his is better. He said that Gannon was willing to custom make him one, so that may be an option if you have a dealer near by that you should try to talk to.

I know that it was not cheap. The side plates alone cost me about $100--altogether I have about $350 in it plus lots of time. i do not know what one would cost from Gannon.

I made mine for standard Cat 1 3pt and almost slavishly copied the design of the Gannon. You can get a few pictures from the parts manual on the Woods Equipment site. Box Scrapers Operator's Manuals

Since I built mine I discovered that Land Pride has a rollover too. Land Pride Box Scraper Manuals

I noticed the main element that rotates is actually flat on the two sides to assist in its operation as a box blade pushing and pulling. The height/depth ration I figur at about 80%. Therefore, my main box side plates are 60 cm by 48 cm. The main box is 120 cm wide (outside to outside) The main beam box is 10mm box with 4mm walls. The side plates are 15mm thick and the drag links and catch arm are 10mm. (I wish that i had used 15 mm thick for side arms. A bit stiffer especially for pushing.)

If I can be of any help or if you want to know a specific dimension ask and I will find it for you. I tried to scan my sketch, but it didn' want to. I need to darken it up a bit and try again, but not tonight.

I have attached a scan of the sketch that I made for my imitation Gannon. I know that the quality is not the best, but it was the best I could do within the forum's restrictions. I managed to get it dark enough that you can see the squares in the drawing paper. The scale is about 1 inch per line (each square is 1 sq in.).

The blade and the top link mast were made from 6 mm (1/4) sheet. The blade was bent 20 degrees 15 cm (6 in) in from the edge on both edges.

If I can help with anything else just ask.

I had a day to work on the imitation Gannon this week so I took the scarifiers to a friend for some hard facing (My tiny little welder does not have the omph necessary), but I finished boxing in the 3 pt mast for strength. I believe that it will hold 50 horses and not just my 15.

I sanded it all with a flap disk, sprayed some primer on it and then some Yanmar Red. I even put a model number on it. YM 4R for 4 feet width and R for Rollover. (R is still in the making) Makes sense anyway to me.

I am very happy with the result of my project and had a lot of fun building it--besides I have already used it to do some of the work for which I made it, as you can see in the pictures.

I hope that you have enjoyed following along and look forward to "seeing you" again in the near future. I need a small trailer to haul all my toys around on.

Have a good one,

Fantastic job on the rollover. I also followed your dirt scoop. Great job there too. Now I want to see the trailer you are going to build to haul them.

Mike

 

[MJPetersen]

Thanks Mike,

I am waiting for my welder friend to get a couple of moments to put the hardfacing on my ripper shanks. Then I will put it all together and do something drastic to test it out. I couple of ideas, but we will see. I will take a picture of things all together.

I would like to start on the trailer right away, but I have a couple of other things that are taking priority and some honey-do's.

I know that the scarifiers really help when the ground is hard. I could not pull it when the 4 scarifiers were buried in the packed soil.

Now that I have the big mounds of dirt cleared away on our church property with the scoop that I made, I need to smooth everything out for the parking area and lawn. The box blade seems to be the tool of choice for such tasks and I drew up some plans for a simple box blade.

However, in reading through the many box blade posts here in TBN I read about the Gannon rollover. The idea and versatility of such a box blade intrigued me. But when I researched them I found that they are HUGE! (35 in x 44 in) All of the models have the same roll over elements only the length of the blade is changed and the number of scarifiers. Obviously not suitable for a YM 1510D. (picture below)

From the specifications on the Woods web site I determined that the ratio between height and depth is about 80% so I drew up a plan for a rollover that is about 48 inches wide, 19 in high, and 24 inches deep. This is still probably a bit big for my tractor, but with the sand that we have here it might work.

I do not have any of the nicer tools that some of you have (I do not have a place for them if I had them and do not have the time for them if I had a place), so I thought that I would try to do this project to encourage others who like me have a minimum of tools. Welder <$100 buzz box, 4 in Dewalt angle grinder (cutting and shaping), and various other hand tools like drills and such.

So we will see how it goes. Any suggestions before it is too late?

In Warsaw,
Mike

These scoops/scrapers have a long history. 100 years ago they were called "fresnos".

Excellent work on the rollover blade MJPetersen!

It's nice to see I'm not the only one who uses hole saws on my steel fabrication projects.

I've cut holes up to 3-1/2" in diameter through 1/2" steel on my Jet 17" drill press. Milwaukee suggests a speed of about 65RPM as I recall; but my drill press' slowest speed is 200RPM. So I use lots of oil, a rigid material setup, two hands on the quill lever to even out the downward pressure, lots of patience, and ear muffs to drown out the noise.

 

[MJPetersen]

Thanks guys. I got the scarifiers back today from my friend so I will put them in and go give it a go maybe next week. I have some mounds of suspicious composition located on the the back side of our property at church. The practice during communist times was to just dump all waste on the the back side of the property. The result is mounds of broken bricks, big lumps of tar and piles of cement/asbestos roofing panels. (Yes I know to be careful of the latter) Given the intervening years these mounds have overgrown with grass and brush. We would like to smooth it all out for a playing field so this is my test project.

mjncad, I think that a lot of people here use hole saws. I read here on TBN somewhere that any through hole bigger than 3/4 inch can best be done with a hole saw. I do not have a press and therefore would not even try the larger sizes yet.

flusher, the scraper that you are referring to is a bit different than the one I built in that they carried the dirt. My FIL had an old fresno type scraper that rolled to dump. Definitely productive and interesting devices.

Off to work.

My only real gripe with hole saws are that by their very nature they are not too accurate. I did buy a set of Silver & Deming twist drills up to 1" diameter for those times when I need something more accurate than a hole saw.

If I encounter a need for accurate holes above 1" in diameter, then I better track down a machinist with a mill and boring bar.

Mike, you are amazing!! wish i had your talents. i have a friend who lives in latvia. near riga. just like you. keep it up. terry

 

[MJPetersen]

Thanks for the compliment. I do not know that I have extraordinary talent in this. One of the reasons that I documented the build is that I wanted to show what could be done with minimum tools and resources.

There was a recent post complaining about not finishing the thread. Since you resurrected this I will try to get some pics and give a final evaluation post. Overall I have been very pleased with the results. It is a good tool.

I have a former student who is from Latvia. He married a Polish girl and they hope to move here to help in our work here. He actually is of Russian decent and when he first came to the Bible college where I taught he had a CCCP (Soviet Socialist Republic) passport.

Hey Mike,
Just finished reading this thread again, and I want to echo what others have said. What a fantastic job on the rollover box. Looks better than a factory built one. Let us know how it works out. Did you make any interesting discoveries in the mystery pile behind your church?

Mike

 

[MJPetersen]

I have enjoyed using the imitation Gannon very much and it works well. I have smoothed the road in front of our church and my driveway, I smoothed the parking area at church and dug a sand pit in the back property. I have used the scarifiers to pull out old curbing and a thin poured sidewalk. I have a couple of things that I would change if I were redoing it today. 1) I found that I would get hung up with the scarifiers because I could not lift the box any higher. If I had put my pivot point a few inches further back I would have gained that much more in clearance. 2)I made the draft arms of the box (the arms that go from the square tube back to the pivot point.) out of 10 mm (3/8 ") material, and I wish that it were thicker, min of 12 mm. 3) I made my pivot point with a piece of pipe inside a piece of pipe with a back up 24mm bolt. I wish that I had used larger pipe for the pivot. I have not broken anything and I have not used it gently. So it is a success from my stand point, although it is really more blade than my traction can pull in our sand. I just run out of traction before I get the blade full or even nearly full. I believe that it could handle a 30 to 50 hp tractor.

I have done some exploratory surgery into the piles in the back, but have not fully leveled things out. I did not find anything too surprising; broken bricks, asbestos tiles, and a few pieces of rusty somethings that went into my metal recycle pile.

Like all the pix great job, and if it isn't available locally then make something. I also live in an area were implements are plentiful. What til you see what I making, just bought a 1986 ? Yanmar 186 for $ 600.00 posting pix check it out. What a steal I got.

 

[sandman2234]

Mike,
Great work, as usual!
I wanted to make sure you are aware of the hazards of pushing with the fine implement in reverse, should you happen to catch something solid in those piles of mystery out back, there is a good chance you can bend your lift arms. I know the lack of traction helps, but it only takes once to bend your lift arms, so be careful.
You really need to quit putting model numbers on your implements. Some poor soul is going to come across one of your implements 100 years from now and spend hundreds of hours trying to figure out what company manufactured it, and how many others might have been built at the same time. If you didn't do such good work, they might realize that they are "homemade", but since you do good work, you are going to fool a lot of people.

Hi Dave,

This random guy dragged this thread out of the depths of 3 years ago. I bent my first lift arms with the scoop before I even made this rollover, but doubt sincerely that the ones that I have now will ever be bent with my tractor. I am aware of the possibilities, but do not worry about it much.

This was one of my early projects and I felt that it should be legitimized by a model number--:laughing:I can see how in the distant future someone could be scratching his head trying to figure it out.:confused2:

i was in Turkey and Georgia (the country) teaching and just got back. Hope all is going well with you.

Mugabe is parasiting on his country, and after he got in trouble, he blamed it on the (white) farmers. The farmers were banned, and black city slickers with no knowledge of farming (all folks that l*ck Mugabe's butt) were appointed to the farms. Our friend told us that the country is quickly running towards bankruptcy, food is allmost unaffordable, and the newspaper wrote last week that by the end of this year, and even more next year, zimbabwe will have a hunger problem as big as countries that are less developed.

(Sounds like South Africa all over again.)

I just ran across this old thread and was amazed at the fantastic job you did. Well, well done.

 

[2manyrocks]

It's a compliment to you that someone would bring this thread back to life.

Earlier this year, I arrived at an auction late, and there was a Gannon scraper there that had already sold. The consolation was that it was probably more than my Yanmar could handle anyway.
