DIY home built scraper pan plans?

[Camdigger]

I've been toying with building a 4' or 6' pan scraper for my small tractors. There used to be scrapers available that used stops and unique linkages to make a scraper function with just oone or at most 2 hydraulic circiuts. Anyone got any pictures or plans?

Cam,
I have some photos of an old Atlas scraper, If this is the type scraper you are referring to.

A 2 wheel scraper using one hydraulic ram and a rope operated dump would not be hard to build. Know a person who built a 1yrd one about 1950 it was based on a horse drawn Gaston scoop, pulled it with an McCormick W30, it shifted a lot of dirt . Intend to build a similar one in time.
One of the main things is getting the pivot points on the bowl in the right place so it will automaticly fall back into the loading position after dumping, lifting the hydraulics to full height also helps the process.
Unfortunatly I cannot post pictures.

If you do a "Overland Scraper" image search on Google, you will see one like mine, in fact a couple of the pictures are of mine. It does have a stop/catch in the half dump position to grade out after dumping, or just general grading. I've used it to grade the driveway, and works great for that.

It is a 6' cut on the bowl, and it does take a good sized tractor to pull it right. They were designed to be pulled with N series Fords, but I have pulled the front wheels off the ground on my 180 Massey, if hooking into some tough soil, so be forewarned..!!

I have moved a good bit of dirt with it, and still have a few jobs for it to do when the time comes.

Thought you might be interested in a mini carry drag scraper I built earlier this year - basically built "free"" out of scrap/salvaged/disused material, , including a disused light old 3PL blade - dimensions 86" wide x 120" long (drawbar) - thought it appropriate to paint in JD green as it will be mostly used behind a JD415, as well as an Iseki TX2160 & Kubota B7100HST.

It's purpose is to spread/set levels/grade raised beds using loose materials (soil, mulch, driveway gravel ...etc) for landscaping around my 3acre yard - all without the "havoc"/consequential damage & clean up my heavy farm/earthmoving equipment creates when using around the house yard....should keep the wife happy (I hope).

Why this design ? Heaps more accurate, higher capacity & quicker than any box blade my CUTç—´ could pull. The 120" long drawbar assists maintaining levels (& makes for easier reversing), the single hyd ram acting on the rear wheels pivots the assembly for cutting, controls dumping, spreading of material & lifts the assembly off the ground for easy unhindered transport/ there's also a old screw adjust 3pl toplink which pivots the RH wheel so the unit can easily be tilted (ideally I'd have fitted another hyd ram but my JD415 doesn't have another remote nor did I have a suitable valve laying around).

Most of the soil I spread is clay/clay loam, this unit works seems great on any softer/looser material (mainly dumped soil, gravel or mulch or after hard ground has been ripped) without weight behind 14-20hp CUT's (the unit is quite heavy with the blade, all the steel, wheel/adjustments mounting behind & the wheels ballasted with 3/4 water)
The combination of the long drawbar & blade angle at the top helps the blade not to ride/float over the material & assist the material to roll/flow in the box -on ripped ground it usually cuts c.4-6" then carry/drags the material for a full load.
In testing well prior to painting I adjusted/rewelded the angles several times to get the right balance of performance across lawn, driveway & dragging ripped clay from an empty pond - I needed something versatile to use around my 3acre+ house yard without leaving the damage/witness marks my farm/earthmoving gear creates.

As for plans this was basically "çhalked on the shed floor & then cut/welded/assembled around this thumbnail sketch.

Also pictured is a carry scoop we have, built in the 1950ç—´ & much modified since then; can be trailed or attached directly to the 3PL ( works great with a hyd top link & on tractors with 3PL downforce ) - this unit requires a lot of HP to run effectively but the basic design can be scaled down to work with any size tractor.

What you call the mini drag scraper is what I know as a land leveller. They are quite common in North America especially in irrigation country and even here in Turkey in the rice fields. Some models common in Canada are rated to several hundred HP and have 30" draw bars and extra long links for the rear wheels. Other models have laser levelling. The ones in Turkey use laser levelling and +/- 100 HP tow units to level ruts left by combines used to harvest the rice.

The old unit looks like a sophisticated tumble big scraper. I don't have big enough pipe to build one. I doubt 24"pipe would give me enough volume.

I based the mini drag scraper on a scaled down version of what we call a "land plane" (fitted with a steerable rear axle/laser levelling/GPS guidance..etc) which we haul with a c.300hp tractor doing much the same thing as what you refer to as a "land leveller" .....funny how the same equiment gathers different names throughout the world....

Is there a specific task you have in mind for the scraper you're trying to build ?

Have a great Christmas

Here's a mini version of some of the big ones we used. Most the really big ones were "double barreled" with an engine in back also and to be sure they got a full load, a D9 Cat pusher behind them.
I liked working with the scrapers as you can move and accurately place a lot of dirt in a hurry, but hated operating them as they not only bounce your guts out, but will quickly bounce you out too if your seat belt isn't fastened.
