Steve - the reason for using the Cat DW-6's they have good drawbar power. They were used to pull the cane wagons out of the fields to the loading ramps for the highway trucks. They would pull a train of wagons out.
USSC was a large customer to Cat. By using the DW-6's they had parts comonality. This all started with the 9U D-6 and continued through the 44A D-6B. Time frame, late 50's & early 60's. USSC was a high usage customer of D-4 & D-5 SA (Special Application)tractors. In the heyday of sugar cane in S.FL there was a half million acres of cane in the ground. The DW-6's did give way to more productive all wheel drive ag tractors as time moved on.

I would be very interested in one. If any one could send me a private message I would be grateful for a lead on one.

Attached are some pictures of starting my D6 for the the first time. After a day of changing fluids upon it's arrival, we decided to pull it across the field a time or two or three. Lesson #1 is it's hard to start a machine in 20 degree weather after it's been sitting 20 years. But I couldn't wait until spring and after a couple passes she finally fired.

This is a postcard showing D6B 44a's lined up outside the dealership in Clewiston, FL.

JEY - this building should look familiar.

I thought I'd just say the Cat in Deas Plant's first picture is still sitting at the same location (more weeds around it now) as of last week. Steve.

7U puller,
That unit in the first picture in Deas Plante's post is the one I saw listed on "California Tractors" awhile back if your interested.

I got the 9u from sebring and have an other.I also have 3 44a's. Looking for 7c15. I've got other cats to thin out. Bill Newman
