In a misspent youth I spent many a day/years watching Yellow Iron move and rearrange dirt, rock & crushed gravel. Got to watch the biggest made by Caterpillar in fact. (#16, D9H tandem, 631's, 641's, 988's etc. ) Of course the dirt of fifty years ago might have been different from that of today?? I did notice operator compentcy could vary considerably. And no; I cannot operate a road grader.
One example of of washboarding? Will that be the complete comparison?
Originally there seemed to be a comparison between LPGS & Backblades. Motor graders were introduced to show a the use of a windrow when maintaining a road. The back blade is able to produce a windrow.

You should see it's big brother work!

I agree with this.^^^
If I had my choice and unlimited budget I would have a motor grader with machine control. Since I don't have much money I use what I have and can afford. A LPGS is something I can afford and I can get by with it.
Two things I don't ever wish for is an old dump truck or an old motor grader. I am satisfied to hire dump trucks and motor graders with good operators, some things I don't need to own.

YOU will have to WAIT a LONG time!
NO ONE EVER SAID I had a motor grader!
Time for yet another re-read!

So, all these LPGS implements that are only about 4-5 feet long must be really worthless for grading a drive or road.?

Must be, I read it on the internet myself. I guess I need to cut mine up before anyone see's me using them. This is totally embarrassing. :ashamed:
Or I could recognize that the detractors have never used a LPGS and don't have any experience with them.

I checked with the local CAT dealer,,, they will take your LPGS in on trade towards a motor grader,,,
It seems that they sell a LOT more LPGS than they sell motor graders,,,
so that old thing is worth something!! :thumbsup:

My understanding of your earlier post was that you are using a rear blade with offset. That is a good tool to have, great for shaping the ditches and building a crown. With enough time and passes you can get nice results. A LPGS is also a good tool for maintaining a properly shaped road and is definitely worthwhile.
You mentioned the issues and advantages of having a long wheel base and that is a valid point. But if motor graders at their high cost is one of the solutions then automatic machine control should also be considered. Even gps automated machine control systems are cheaper than a motor grader. I can only afford the laser automatic machine control and that is good for flat or planar work.
I should also mention that most of us using the LPGS are running them with the 3pt in the fully lowered position. Having the front wheels drop in a dip does not make the implement rise up. You can for practical purposes slide over a dip that is about half the span of the LPGS skids length and maintain grade. A LPGS is a great tool for averaging and making the surface flat. When used properly it will maintain a crowned road with a quick pass up and down each side of the center line.
If you use a rear blade, LPGS and a heavy roller these tools will go a long way to building a nice driveway that will last.

May not have operated but used more than one at the same time.
Now you can use a grader but that doesn't mean you can operate one. There is a difference.
