How fast for maintenance grading?

I agree. Agree to disagree does help keep the feathers down. Blood pressure,the jury is still out on that one. lol

I had an old boy (geeeze now I'm one of them ...almost ha ha),tell me. Kid,there are two kinds of people on equipment. Lever pullers and operators... and it's easy to see who's who on a the motorgraders. It's fun watching a new "know-it-all" get on a grader when one of the old boys retires here. ...and they're going to "show us how it's really done". I learned over the many years,let them get thrown off the horse a few times and they'll listen allot better if they really want to learn something.

What are running for a grader MadMax?

On edit...see you're operating a Deere (viewed some more posts of yours)

I've got a question for you though MKTEF, do you ever have a problem with snow dust clogging your air filter??? One time last year I was about ten hours into pushing a dry, dusty snow and my air cleaner sensor went off. I stopped and opened the airbox to find it full of snow. I cleaned it out and shook all the snow out of the outer filter and went back to work. Only happened to me once.

We had the same problems with the stock Cat precleaners..I put a cyclone ejector on all our graders and haven't had any issues with snow or dirt.

i used to have the same problem with the 140 that I ran in Manitoba. I solved it with a pair of my girl friends panty hose. I covered over the whole airbreather, acting as 'dust screen'.
I never had a problem with the filter in the winter after that. the girlfriend , that was another issue, for another forum

Bah ha ha....read this post and about died laughing,,,,,are any of you high speed grader operators still employed as an operator.....hehhhehhe hi g4

Grandpa
Right on. When I saw the topic had been resurrected I thought, OH No here we go again. I stayed away from this topic a couple years ago because I simply could not believe some of what I was reading. I thought I was in the “Twilight Zone”. Anyways thanks for a good laugh this evening.
Regards, Randy

Yeah...thanks Grandpa...:Banghead...lol...:drinkup

Actually I quit because none of the old dogs would listen!!!
Sorry GRAMPS!!!!!!!!!!!!!!!!!!!!!!!!!!

Any operator who is not grading as fast as possible without compromising quality,safety and the integrity of the machine they operate is a plodder. I have invented and sold a patent to a cutting edge that enables a road to be graded as fast as available horsepower and safety will allow. The reason high speed grading is now an option is that this invention eliminates grader bounce, the biggest inhibiting factor in grading speed. Use of this cutting edge will allow a grading productivity increase of a minimum 40% in most grading applications. An increase of 40% is equivalent to the selection of one higher gear. Most graders gears have increments of 40% to each gear.
I have graded at 30kph with this cutting edge and can tell you it was scary, material leaving the blade was spread more than 12 feet from the blade, any rocks were thown from the road completely. This exercise was done purely to prove that the cutting edges stopped grader bounce. Testing of this cutting edge proved that vastly increased productive grading speeds (up to 20kph in some conditions) could be achieved.

Can't see that working very well. Maybe for some snow plowing but not any kind of real grading. That's just like a 3" thick cutting edge. I've seen highway dept. doubling up plow blades for wear but I can't see it on a cutting edge.:beatsme

i seem to recall somthing simular to that posted here a few years ago. it was a device that was mounted on the back of the mouldboard and was operated hydraulicly, you could very the amount of pressure you placed on the ground whild blading. ill see what i can find.

ok found it, it was from a post made by Countryboy on 10-11-2007 in the "Weird Grader applications" page 10. here is the link. i think this is simular.

here is a post to the exact post, for those who have changed the "display XX post per page" the other post won't work.

When I first tried this cutting edge I had no idea how it would work, my only intention for making it was that I was extemely frustrated at being restricted by grader bounce at increased speeds. I have trialled it extensively and the improvement in grader stability, control, ease of operation and finish was amazing. Instead of constantly fighting for control of the blade the cutting edge provided the stability required in constuction and finishing applications with substantial productivity increases. With every grader movement or bounce with traditional blades you get a corresponding fault in the graded surface, the only way to eliminate these faults is to slow down to achieve grader stability These edges improves grader stability unbelievably, the cutting edges maintain an extraordinary sharp, chisel like cutting edge in most applications. The surface finish is superior in that the graded surface has a trowled and extremely smooth surface. The only area where I would not use them is hard dry surfaces (or frozen gound)as penetration is not as good as conventional edges. In all other applications, especially construction and most maintenance grading situations they are vastly superior to conventional edges
Operating a grader with the new cutting edges is a totally new experience, it is relaxing and you feel like you are are sitting in an armchair instead of being tensed up anticipating the next grader movement or bounce and appropriate blade adjustment.

To experience these edges ability I suggest you do as I did, weld a used blade to the back of a new one and experiment. I found that having the blade rolled back fully (John Deere) and then welding the old blade horizontal with the ground worked the best, it allowed optimum rolling on the board and increased loads.

Hey, It could work. You don't know sometimes unless you try. Sometimes things look like they wouldn't work and to your surprise they work great. Good luck with it.:beatsme

Got to thinking about all the different post and so I thought i'd make my own experiment.. Took a 6x6 wood block ( The ground is froze here in Minnesota) and drilled a two inch hole about half way thru the block, then went into the aggregate testing room and got two handfuls of certified road base. Layed one hand full on the block, took a piece of angle iron and drug the aggregate across the hole. This action pretty much fill the hole up to the top, (coulda used a little compaction tho). Next I took the second handful and tossed it across the block simulating 20 mph( my best guess) and you were right, it took 15 seconds to pull it across with the angle iron and less than a second with the toss method.....sure did save a bunch of time.:notworthy

Thanks for the test procedure manuel Grader4me, it was useful in maintaining proper test parameters...ef ef

Even I couldn't dream up a yarn like that...head hurt?? lol

Speed gradin does work if the road is smooth, if you have one bump.......then you have seven..................so slow is better on an uneven surface.......roger......
