Dirt Moving Capacity of D6

[farmeraaron]

Can a D6 pull a 25' disk with 24" blades? Thanks Aaron Mostly flat ground, sandy loam, traction is the issue here in the Northwest.

A D6 dozer?

Which D6, what type of disk? There are many different D6s over the years, lot of weight and track variables. An offset or tandem disk? They do not pull the same. I can tell you that ours would not do it. But then ours is out of the 40s and only weighs 18,000lbs and has 22inch pads if I remember right. I pull an old Kielfer-John Deere 12' offset disk with 24" pans. We have mostly rolling hills and I have to use 2nd & 3rd gear. Moisture content along with steepness of the ground dictates what gear I'm able to use. My initial thought is that the disk is too big, but really need to know all the weights and type of disk to give a good evaluation.

I would add "How fast do you wan't to pull it?" to this question. I think a D6C or newer will pull it but not sure it can pull it fast enough to work well. I would suspect you need more power to get the speed up.

Just a general question. I know very little about crawlers and wondered about the pulling capacity. I looked at tractordata.com for some information but was having a hard time reaching a conclusion. I have a Versatile 750 (with a 350 Cummin small block) that pulls it at 6 mph. The horsepower is different but I thought maybe the Cat would be more efficient horsepower to ground. Also the Cat seemed to weigh more hence better traction. We are irrigated, so I would say the ground work occurs at close to field capacity. We also pull a 27' packer behind it. Thanks for the input.

The disk is an AC 3400 tandem disk. It is heavy.

I would have to agree with Steve.
I think a "newer" D6 would pull it, a very rough guess would be, again depending on the model, between 28K and 38K. The problem is dozers are really not designed for towing or speed, to be going at a good speed to pull a big harrow for a good amount of time would be a teeth rattler, IMO. Unless you're on absolutely flat manicured ground...
I have a D4 sized dozer with 3 speeds, I hardly ever use 3rd cause it feels like your in the middle of an earthquake....:laughing:

What do you mean small block...do you mean small cam 855turbo or has the motor been changed for a L10 or 8.3cdc..How do you get 350 from it?

 

[farmeraaron]

Yes, I meant small cam (I thought small block did not sound right )engine has been replaced Cummins. Thanks for the correction. Sounds like a crawler may not be the answer I was thinking it was. I wanted a tractor I could use to pull my drill and disk both. The tractor wheels tend to make deep tracks in the seedbed that can be felt in following years(3). Thanks, Aaron
Is your D7 a farm cat?

Our old 6 is a 4 speed and 4th gear is flat out SCARRY. :shocked: As far as the ride, I feel that the ride is smoother than my wheeled tractors and our ground is far from flat manicured ground. I'm guessing that it is the size of the tractor, my Case 310 dozer is a rough ride in 3rd gear also.

I think that the OP may need a D7 or D8 to do what he wants to do. The farmers that are to the East of us used to run D4s and D6s and are farming 1000s of acres, none of them pulled anything that wide. Most of them have gone to wheeled machines.

No a bush CAT ....Working land with cats is a noisy, hard ride and too slow , more for an enthusiast....you have a good tractor, just put some chisel plough legs behind the tyres to irradicate the tracks in front of the drill !
