Clewiston Tractor, now Kelly Caterpillar, in Clewiston Florida was contracted by US Sugar Corporation in Clewiston Florida to build rubber tire tractors to pull cane wagons from field to factory in the mid 1950’s. The Caterpillar D6 9U tractor served as the base unit with the custom wheel conversion added. Later in the early 1960’s the Caterpillar D6 B series was used as the base model when US sugar ordered additional units for its Louisiana plant. It is estimated that a total of 100+ units were produced. The DW6 has found its way into multiple applications for pulling circus wagons to adding blades and used in construction. At one time it was discussed by Canadian Caterpillar Dealers Geo.W. Crothers Limited and Hewitt Equipment to produce a DW2 and DW4. I do not have any records of those machines being produced or know of an example around today but i would love to have one, please see pictures below.
Caterpillar offered a D4 conversion called the DW4, and a D2 conversion called the DW2.

Here some pictures of my DW6B just after restoration.
The largest one made was for the King Ranch in Texas, they converted a D9 into a wheeled tractor.
