why this type of grader does not exist???

Hi guys:notworthy ,why this type of grader does not exist?It would be a motor grader but put metal or rubber tracks.No wheels,a track grader.I know it looking to be a bulldozer but it`s a great idea?


THANKS

Probably for the simple reason that there is not a need for one. Tracks are for very soft or muddy areas where the extra flotation is needed or places where stability is needed. These conditions are places where a grader wouldn't be of much use any ways. This is not to say that there wouldn't be a special circumstance where one with tracks would be appropiate but by the nature of the grader, it would not be very functional in these conditions.

If one was to need a grader with tracks there are many track systems that are easily adapted to a grader. There just aren't many applications where tracks would be more productive than wheels in terms of a grader.

Because as each chain link hits the sprocket, the whole machine jiggles a bit. You can't get as smooth grading with a tracked machine.

Hi, Folks.
Just for the record, some of the early self-propelled graders were actually grader frames that fitted to a crawler tractor. The Russell Grader Company, since bought out by Cat., used to build models to suit Cat Fifteen and Twenty crawlers. You could drive the crawler into the grader frame, connect up all the controls, etc., and go to work.

If you wanted your tractor back to go do some plowing, you just disconnected everything, backed the crawler out and off you went. Well, maybe that is a little over-simplified but it is basically how it went.

Deere's new 764 HSD, check it out at

thats not a grader

[J.BobbyM]

As a machine form the 764 is more readily associated with the crawler Dozer. However functionally it was designed to perform many tasks associated with graders (knockdown, rough and fine grading at speeds and accuracy exceeding dozers. In many ways it should be considered a hybrid grader-dozer.

Looks and sounds like it would be a quite a machine. Thanks for the link.

So, do we call it a "Grozer"? ***

Cool! And since the name was my suggestion, if the Copyright doesn't work out for some reason, you can sue me and we'll split it. :notworthy

I was thinking of "Dazder"....I get this "Dazed" expression on my face when I look at that machine Lol

Grader4me is currently trying to work out what colour dress would go best for operating that machine:rolleyes:;)

interesting machine. the ground pressure seems high at 6.1 or so psi.

what the farming boys found with the tracked challenger type ag tractors was that the compaction was higher than the wheeled tractors because apparently the tracks load more at one end.

I can see uses for this machine, beach cleanups etc but I'd just hate to hink of the cost of the tracks and the fact that'd they'd probably be throwaway every 1000 hours or so if a tracked skid is any guide.

Wow, that does suprise me, but it also makes a certain amount of sense.
Still a suprise though.

I'm very surprised as I have been at the Dowerin Field Day when the university has been out testing the compaction; and they told us chums that the tracked machines were putting down a lot less ground pressure.:beatsme

But, not to get too far off topic, I like to look at it this way. We went from Steigers of around 400 Hp to Challengers of 210 Hp that just ate the wheeled Steigers for breakfast in our sandy loams. What this ultimatley meant is that (on a pound for pound basis) we pulled wider spreads so we did less laps around the paddock...thus less "compacted" area. JMHO

[Steve Frazier]

I'm surprised no one mentioned roadability as a reason. Around here, all the towns drive their graders from job to job. Graders are also used in snow removal by a lot of municipalities, tracks wouldn't work in that application either. I think a tracked grader would be so job specific that there wouldn't be enough market to warrant manufacturing it.

i guess it depends on your application - i was relating what i'd been told by someone who should very definitely know though the application is dryland black soils.

way he described it is the things are technically fine but when you load them up pulling ploughs and such like the pressure rises and that they were getting less compaction out of properly setup wheeled tractors running correct pressures.

the stuff this guy pulls round the paddock i dont think your 220 challenger would budge, he runs the biggest tractors he can get his hands on, he was casting a look over one of the new big wheeled challengers but picked up four headers instead.

as you say steve, it'd be a pretty specific market tho squizzy likes to play in the sandpits... ;)

This is an interesting thread, because quite a few times over the years, I have often wished that I had a grader with tracks. We do quite a lot of work grading sand drift banks from fencelines and it is a real work of art trying push in dry sand, two or three feet deep. We also build a lot of farm roads, where we are grading rocks out into windrows for rolling with stone rollers, until the rock is crushed down to gravel. This is murder on tyres. Grading fenclines over limestone reefs would be a lot easier with tracks as well, because the blade will hook on a reef with the tyres spinning, tearing rubber off on the rocks, whereas with tracks we could cut straight through the reef. These are all jobs where finish isn't terribly important and of course with everything else that graders do, tracks would be totally impractical.

Rn'R.

Hello Equipmentfan ,

I put onder my old O&K 156A grader michelin 555x70x25 XHF tyres and than you need tracks , this tyres are of the floting type with low pressure . This tyres are between the 17.5x25 and the 20.5x25 but wider then the 20.5x25 , and this tyres made a bulldozer from your grader .

Do you mean something like this , see tthe pic,s .

[stumpjumper83]

So let me get this straight, you want a tracked grader. So we are going to take a regular grader and put on tracks instead of tires. Now that we have tracks, the machine is more stable, since its more stable, we dont need the tires up front. Now that we have removed the front, we will move the operators station to the middle for a better feel of whats going on... look at that, we have a dozer... but with alot of extra levers

[Taylortractornu]

I talked to a man that was working a job LA and southern MS that did logging roads and other wet areas. He had forestry tracks like a forwarder had on his grader and then one had a set of rubber over the tire tracks. Also one of his trucks had them on the tandems. He had 4 lowboys full of neat stuff. He said the one with the forestry tracks was a tough rigs for working in blue gumb base roads.

i gues that metal tracks would ruin the job, when turning the machine

[Old Grader Guy]

I guess the whole purpose of fitting tracks would be to increase the traction. Being involved with graders for more than 30 years, I say you can't make dozer out of grader as you cannot make grader out of dozer. Each of those machines have specific features and suits specific applications. Mix that and you will get mediocre grader and bad dozer.
