Although nowhere near as popular as the crawler variety of dozer, you should still find the odd Caterpillar wheel dozer for sale at Plant Pages.
All modes start with an '8' from the 824 to the 854 (current model lineup lettering is 'K').
These are big units, with the smallest operating weight at 34 tonnes, rising up to over 100 tonnes for the 854.
CAT wheel dozers are typically used in surface mining, cleanup, road maintenance and jobs where travel between sites is important. Read More Info & View Caterpillar Wheeled Dozers for sale...>
