Hi, Case On A Cat.
See if you can control your salivary glands while watching this video.

just my 0.02.

Deas,

These machines are fast, efficient, smooth, easy riding, and very productive - BUT I doubt they are no where near the FUN of moving earth with a D8 14A or 46A pulling a 435, 70 or equal!

On the second vid, the design of the rear wheels makes them act like the rear of a grader. Interesting design.

The Bagsshaw scoops you see in the second video are by far the most common scoops in Australia they are extremely fast as in almost but not quite road gear when leveling and have a almost zero rock from side to side at speed which greatly reduces the amount of constant clean up than can be required with high speed leveling

Those Bagshaw scoops were designed by a farmer and sold under the Allfarm name until Bagshaw bought the company they have 3 or 4 well spaced wheels on each side on a rocker setup they are nice and low so you get see exactly whats going if you can thru the dust and they are very strong as well

The only down sides are the bowl is deep so depending on what your trying to load they can be a challenge at times to fully fill the back of the bowl and the other problem is they dont eject the dirt but that is never really a major problem as you just wait a day or so and then go when the dirt is drier or at least thats what I have with those Bagshaws

Hi, JanM.
Yes, I have seen that design before in other videos but never up close and personal. I would think it would better for both flotation and compaction with both wheels on each side having an equal share of the weight all the time. That JD seemed to load that scraper pretty quick too - wonder what yardage it was getting?

There is a line in Wind In The Willows, "Nothing is half so much fun as simply messing about in boats." I seriously doubt that author had ever had 'Cat Yellow Fever' or ever messed about with a 'Cat-n-can'.

I still don't think they can match a good spread of open-bowlers and push cats in bulk earth moving and CERTAINLY not in anything remotely rocky. Good loading, yeah, maybe, and on shorter hauls, but let the going get a little tough and - - - - - the TOUGH get going. I'd like to see them getting down the haul road at 45 MPH with 54 cu. yds of shot and/or ripped rock in the bowl after loading in around 25 - 30 seconds - - - or less - - like a Cat 660 or 666.

Just my 0.02.

I can't help but wonder when that poor farm tractor's hitch is going to break right clean off! (The first vid with the front wheel assist tractor) Looks like a huge over load carrying on the drawbar.

MMM... Pull Scrapers

Yeah seems like a lot of weight for the tractors hitch to handle.

These buckets , as they are called here, normally have a improved hitch fitted . often a cushion hitch.
Used for laser leveling of irrigation ground devoid of rocks.
I operated one for a while pulled buy a Stiger tractor with a Spicer manual gear box. Certainly learn how to change gears.

Same here on the dedicated scraper tractors used by the professionals.

The laser scoops buckets or pans depending on the part of the world your from are very efficient for 99% of earth works in Australia so much so that they out perform wheeled scrapers in almost every operation these days

Many years ago I asked the then biggest laser scoop operator in Australia about this (he lived only a couple of farms away from me) how could this be after all Cat have been making scrapers for years and there bowls are bigger ???

His answer I have never forgotten "well Paul its like this I can buy a tractor and scoop for less than half the price, there is never any reason to push or pull to load a scoop so we save a operator there and when we twin scoop we shift more than biggest scraper with only one operator "

Now I have never checked the science into these claims and accepted these at face value as his operation used to be all scrapers dozers and road graders but they only had one road grader left and the rest of the plant was scoops and tractors

They made a lot of their own scoops as the Bagshaw scoops werent around, last time I checked he was slowly swapping over to Bagshaws as well or at least thats what appeared to be the case

The Australian scoops appear to be a lot different than the US built ones

The US built ones appear to be more scraper based than the Aussie laser scoop

I stand to be corrected on all of this

And Andrew I have spent many nights in a Stieger cougar manual on laser grading and took me a while to get used to or should I say master changing on the go with de-accelorator pedal I found drop cogs before you load and skip shift down to the gear I want and only shift the main box on the move I was never good enough to shift either of the transfer box gears on the move then once I was loaded pick the scoop up and shift up thru main box on the move

But the de-accelorator pedal took a few nights to get used to LOL

The cushion hitches on the tractors I have driven are hydraluic self leveling and cushioned and I reckon have at least 8 inches of up and down movement in total, we would turn the hitch off and let the draw bar ride on its stops for ripping
