Buying right scraper size to pull behind tractor

And whether he gets much done is going to depend a lot on how wide the cutting bit is. The Laplant-Choate C40 pan in this thread has been pulled with a JD 4020, but it had a "frost bit" in the center back then. It worked OK as long as the cut was long and shallow enough to only engage the frost bit The 2WD 90-ish Hp 4020 would have been pretty close to the tractor he's got.

To load in reasonable distances and get a lot done, the MFWD 4955 Deere is by far the best tractor we ever put on it. Still had to careful or it was easy to choke the 225+ Hp tractor down when it really got a good bite.

Thankyou ccjersey for the reply.The way it sounds it is going to be a little big going with the 5 yard.I will try and talk him down a yard ot two.

He would be better off to put a loader on it and truck the dirt. But I guess what ever floats there boat.

I was told that the Cat 40 scraper works real good behind a 100HP tractor and its 4 yards.

Well I use a 10 foot scoop behind a wheel tractor 120hp FWA carrys about 8 yards the difference between this scoop and the ones shown is the tractor carrys half the wait of the scoop and it has a telescopic bowl so I dont have to push the dirt very far !
Most of the power in dirt shifting with a scoop is to push the dirt to the back of the bowl so these type of scoops dont need much power and give really good grip on the tractor tyres as the more dirt I load the more grip I get
I always use tractor tyres with water in them as much as I can get the grip it gives compared to no water is unbelievable
hope this waffle is of some interest

Interesting Paul - is reducing the effort required to "push" the dirt to the back of the scraper one of the benefits of an elevating scraper? (I know nothing about this topic...)

Neil in a word yes because just like pushing dirt to the back of the bowl also pushing dirt up high in a pile takes a lot of power
when there is a scoop with a apron on it to close the bowl off and you try to fill the bowl fully you use a huge amount of power pulling in the last of the dirt were as when there is a elevating chain it pulls the last of the dirt in for you
I dont know whether Im explaining this properly but Im sure some one else can chime in and explain it better

Makes sense to me! I have seen some small homebuilt scrapers on youtube that appear to be non-US in design, based on the wheel spin they get with larger tractors it makes sense that it would take more power to fill a bowl. Also think of it another way, tractors were originally rated as 1 plow, 2 plows, etc. Think of the width of 14 inches buried 4 inches down as the max you can pull. Now try taking extra power to heap that up as dead weight you are pushing into the scraper bowl! You have by all rights just exceeded the capacity of your tractor!
(I know I have old tractors)

I use a eversman 2sd behind my 5525 jd and it works very well . This is around 90 horse 4 wheel drive. Carries about 3 yd heaped. Ron Meeder
