Grading an "Interesting" Driveway

[fried1765]

I lived with gravel drives almost my whole life and maintaining them is a never ending job. Steep drives are really a pain and to keep the water damage to a minimum requires lots of rock, ditching, and colverts. Tight curves and loose gravel are good problem areas also. A heavy roller to pack the rock helps after grading I have found out. And the heavier the roller the better. I have a curve that isn't sharp but it's probably a couple hundred feet long or longer and that's my biggest area of problems. No problem with run off from rain but with delivery trucks and hot rods that think their on the interstate. I'm going to solve the problem of rock getting pushed and threw off in the yard by putting in a nice speed bump. It is aggravating spending thousands of dollars putting rock on the drive and having some ya-ho's come flying in throwing rock everywhere. I feel like i spent the money on rock for the drive not the yard. No one is in that much of a hurry that they have to drive that almost thousand feet in under two seconds. I always have consideration on someone's property knowing how much work and money is spent on keeping up a drive.

I have a 2100 foot long gravel driveway, through a wooded area, and a small hill with a curve.
Because of excessive speed, on the curve, the gravel migrates to the outer driveway edge.
I do think that my..... "Caution - Moose Crossing"..... sign may help a little bit (it is a joke of course).
It is at my seasonal residence in Canada, so there actually is a slight bit of credibility.
Cow crossing...deer crossing....sheep/goats/horses/turkeys etc. are other more believable sign subject possibilities.

Get a land plane or build one - it will be the best tool you ever have for that - will just require regular maintenance to keep it up but its not hard to drive a tractor up and down the lane a few times a year.

I just finished my fall grading of our driveway, and in light of all the discussions on this topic from time to time I thought I'd share the challenges involved.

The driveway is gravel, a quarter mile long, and gains 150 ft. in elevation, for an average grade of 14%, though it's not uniform and some parts are steeper. The top is at 3,500 ft. elevation, in the Blue Ridge in western North Carolina, so we get snow and/or ice most years, but highly variable. We also get heavy rains from time to time, so washing is an issue. Parts drain to both sides and other parts all to one side.

The objectives in grading are to recover the gravel thrown to the side by traffic and in the process eliminate the depressed tire tracks that cause water to run down the road instead of off to the side, and to remove wash-boarding that develops at several points. I know there are strong partisans in support of various attachments for this task, but I use just a rear angle blade on my JD 870. This time I made one pass up each side to move the gravel into the center, then a pass back-blading to spread it off the center into the tracks, and one final round trip with the back-blade to touch up parts that still needed a little help.

There is little loose gravel - it's all packed or it would toss quickly with traffic. I wait until there's enough rain to make it easy to cut where needed and to re-pack quickly.

Knowing that it "didn't happen without pictures," here's the photos. Starting at the bottom, off the paved road.

This section drains to both sides, and is pretty steep. It wash-boards badly on the right side on the straightaway for some reason. The challenge is to grade out the wash-boards without destroying the shallow drain just above the planter. It wash-boards on the left side in the corner, but that's less of a problem to grade out.

This section is less steep, but has a shallow "S" curve, and transitions to a right-side drain only.

This section is not too steep, but drains only to the right, so has to be graded flat across so the water runs into the ditch and not down the road. This section was a state road until abandoned 40 years ago, and we only own the right half, so can't re-grade the left side.

You can see the old road continuing straight while our drive turns to the right. The curve is fairly steep, and wash-boards badly on the right side. I also have to take care to not cut a ditch past the shallow drain at the lower right corner of the photo.

This section drains to both sides, and is fairly steep. It faces north-west so even with the leaves off snow and ice doesn't melt well, so the tire tracks need to be graded out so if it snows it can be plowed clean.

This little section is nearly level, so presents a challenge to adjust the depth of the blade both coming onto it, and going out into the curve beyond.

This section is steep and is shaded by the pines, so snow doesn't melt well here either, so again the tire tracks need to be graded out to facilitate snow plowing.

This curve at the top is pretty steep and the inside wash-boards noticeably. It's banked, so there is a transition from crowned to banked and back to crowned.

We're at the top. The ditch on the right tends to fill with gravel that has to be recovered, and the parking area on the left accumulates gravel from plowing snow that has to be returned, but otherwise not much problem. End of tour.

Excellent explanation, and photo documentation, Terry.
The land plane may have it's place in some relatively dry areas of the country, but the rear blade is the ONLY tractor drawn implement for driveways like yours, and mine.
The wider the blade the better! (I have an 84" with 16" more offset)
I have been using a rear blade for 45 years, and consider that I have become rather proficient with it. Most of that grading time was spent using a blade behind an 8N.
Because I can do such an such an effective job with the blade, I have usually only used it twice each year.

How do you drive the tractor and run the grader at the same time?

Set the tilt (crown)manually, and then it is just a matter of up or down with the 3 point.

That's the bees knees.

Thanks, guys.

DT86,

Yes it does look a lot like SW Virginia around here. Very pretty country.

Thanks for directing me here Terry. All these threads are an education. Actively looking for a quality used offset-capable rear blade.

You're welcome Buggs. My blade is offset-capable, and has an adjustment that allows the angle horizontally to be set which is supposed to be useful for cleaning ditchlines. But can't remember the last time I used either adjustment. I find I get the best results by setting blade to the angle side to side that works, then adjusting to the top link to move the leading corner up or down thus setting the angle across the roadway.

I do wait until the ground is a bit moist so I'm not trying to dig in to hard dry ground. I'm not worried about setting the angle of attack on the blade to cut into hard ground.

I have a 60" blade, and the rear tires are set as wide as they will go on my JD 870 for stability on our hillside, but haven't found the need for a wider blade. I suppose a few more inches might be useful, but it doesn't trouble me enough to think of replacing it.
