Proper equipment is paramount in any undertaking.

I'd love to have some sort of mini mid mount grader.

I find my new top dresser an incredibly valuable tool for dressing the driveway. But you have to fix the dips first.

So ...the county bought a new Deere.
Did the price determine Deere over Cat?

I didn't search this out but what is meant by "Wash Boarding" ?

What I think it is, is a rippled effect on the road bed, but I do not know for sure why it got there ?

I have seen so many dirt roads in my area with a rippling effect on them but I always thought it was caused by poor Box Blade use.

An old friend who was in the gravel business in a big way, always complained that the Grader Operators were driving too fast, bouncing and the mouldboard was making the ripples. Maybe a grader operator (does anyone know any) could chime in. I do believe that at least some are made by vehicles and their suspensions bouncing. At one point, I thought some might be exposed cordoroy (sp?) roads.

Thx, let me blow this out a little further.

The road that stands outs is a well graded road, wide, flat no pot holes... hard to believe it is vehicles but I take you guys knowledge base as good.

I long ago read a report from the Army at Yuma Proving Ground, trying to eliminate washboard in gravel roads. They found that below a certain speed, they would not form, and above that speed, they could not be prevented. IIRC, the speed was 18 MPH. With lighter, softer sprung cars, the speed may be different.

Is there merit in digging up the aggregate? And forming a new surface? I always wondered about that. It seems to me if you leave a road basically as hard as it was and just pull stuff into the potholes, they will form again in the same place, in short order.

No doubt about potholes forming again after filling. If you have a box blade with ripper shanks, lower shanks and rip up a few feet around the hold, fill and compact with repeated wheel travel.

Lot of good points raised by all. I take care of a couple of gravel common drives in my 'hood and on my 4720 I use a Land Pride power rake- like a Harley except it doesn't have "nubs/spikes", instead it has 3/4 x 3/4" ribs on the drum- plus a very heavy 72" box blade with ripper shanks. If I'm just fixing pot holes I use BB. If I'm bringing in new material (graded base 3/4" bluestone mixed with stone dust-heavy stuff-no voids) I'll put the Land Pride on-which by the way Land pride no longer makes my model for 3 pt hitch mounts

Agree, key point is get water off road ASAP- Crown is important, and once you have established, biggest problem I have is if we have an early snow fall-like 15" we got two days ago, and road hasn't frozen yet, plow contractors come in and first pass they go right down the middle-not the best for keeping your crown! I've told owners.."tell your plow guy to come in angle to right and turn around and same going out- but its like talking to the wall In addition to crown, I make it a point to create cuts at edge to get flow off road on long runs instead of volume building.

Agree for sure speed is also a killer. Some of these people think its the Baja!

Also when I do major pot hole repair, I will rent a plate compactor-around here its like 50/60 bucks for 4 hours. If I'm doing "major" and bringing new material in and doing long run, I'll "rent" a vibe (steel drum, rubber drive wheels) or a double drum steel vibe- depending which friend has availability-cash payments work!

Somewhat. Cat only offered high tech joystick equipment that is expensive and unnecessary. Cat has figured that out after 12 years and in 2020 will offer their graders with standard rack controls. Sales loss has driven that.
