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.

Catchyalater.

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.
