Yesterday while doing my rounds for work I got behind a lowboy hauling a real nice D9H through southern Wisc. The machine was in like new condtion. I am sure it had been redone, but looked good. As a added bonus the tractor pulling the unit was a real nice R-Model Mack. Both pieces looked nice going down the road headed toward ILL.

tw,

There are a few 90V Series D9H's around southeast Wisconsin. One I've seen has a pushin' cushin' on it and one with an S blade. The latter I believe is a very late model 90V. I know who owns the first one I mentioned but can't recall the name. I believe it's Wanaseck (probobly mis-spelled).

We just finish selling the last 5 D9H we owned.I always liked the sound of those old G's better than the H's.They just seem to have more bark than the newer ones.We had them set up with and without rippers,and we had acouple with the c blade,these tractor had to be the hardest tractor to try and carry a grade with.

Hi, Hicrop10.
I dunno. Maybe I've got radar of laser or GPS - or something - built in but I really liked those old 9's for carrying a grade. I used them a fair bit for making haul roads to get dump trucks into all sorts of places on a couple of iron ore railway projects in Western Australia, DownUnder, back in the 1960's and cut a good few more roads elsewhere with them at different times. I also cut quite a few beds for Armco culvert pipes with a D9G - +/- 1" and whatever fall they had designed into it.

In one quarry where I operated a D9H for 9 months, I was the grader operator for the haul roads and for the main access for the road trucks hauling the product out and the D9H WAS the grader.

I do agree that the 9G's had a better 'bark' than the later H's. My hearing will testify to that. I worked one in a railway tunnel for 6 weeks.

You have a wonderful day. Best wishes. Deas Plant.

Deas Plant,sorry I should have explained myself better.What I meant about the grading was with the c blade on the tractors.The d9's we had with the s blade were great tractors to grade with. We did a reservoir job back here and I did most of the slopes with a D9H. The slopes were 3 to 1's and about 150-200' in lenght.Have a good day.

Hi guys,

I am a bit confused. When you talk about the c blade are you talking about an angle blade with the c frame? I have a D9 19A and have only used it with the straight blade although I have a semi u bladefor it. I haven't done much road building with it(mostlyworking rock in the pit) but it seems to grade as well or better than the 2U I have had for 30+ years. I have hyd tilt on both Cats and I am now spoiled to where I would not want to make road without it. Do you think that the semi u blade will not grade as well as the straight? firpitch

I think the "C" blade referred to is the short blade mounted on the inside of the track frames that was mostly used as a "pusher" unit for the scrapers but could do some dozing as well.

rch101, The outfit you speack of are out of Burlington. I have spoken to the founder a few times. He is a HCEA member.
The unit I saw was on hwy 12. I followed it from just south of Whitewater to just outside of Elkhorn when I got a chance to pass it. The blade was taller than I am, and at hung over the low boy at least 2 ft on each side. From the name on the tractor I could see it was headed towards ILL. One of the Chapter 4 members knows the trucker so I am trying to find out where it went. It was raining and it was hard to try and shoot a picture of it when with 5 cars behind me trying to get around it also.

Found the D9H a great machine to operate provided they were fitted with an open ROPS, I did not like the enclosed cab, in my opinion these machines were not designed for them.

In my neck of the woods, the D9H wasn't a great performer, and the extra 25HP that Cat squeezed out of them, over the D9G, to try and keep up in the HP race, made them unreliable. The late D9G's were the best model of the flat track D9 that Cat produced.

Hi, Firpitch.
The 'C' blade is the cushion push blade for push-loading scrapers. As Old Magnet said, it is mounted to push trunnions located inside the tracks on the main frame of the tractor. It is also only about the same width as the outside of the tracks and has shock absorbers built in to allow for picking up scrapers from directly behind without beating the scraper operator half to death - - - not that some of 'em don't need it from time to time. LOL.

A 'straight' blade has the cutting edge in a single straight line right across the blade face and vertical ends.

A 'semi-U' blade has the corner tips and the ends above the corner tips angled forward on each side to help keep the dirt contained within the blade face.

A 'U' blade has about 1/4 to 1/3 of the blade width on each side angled forward to act as a sort of bowl to carry more material for bulk pushing applications such as stockpile work.

An 'angle' blade has the actual blade pivotted in the center on a 'C' frame and adjustable braces each side with usually 3 separate anchor points on each side of the 'C' frame to allow the blade to be angled one way or the other or set square across the machine. An angle blade usually has a cutting edge that is a straight line all the way across and the sides are scalloped inwards in a curve between the corner tip and the top of the blade. This scallop allows the blade to present a more or less straight edge to the forward side of the cut when the blade is angled.

These are just a few of the more common permutations of 'dozer blade'.

Hope this helps.

You have a wonderful day. Best wishes. Deas Plant.
