Wheels of Time Announces the Willis-Chalmers

HD-21 Crawler Dozer

This was the competition for the Caterpillar (Cat) D-8. The HD-21 was produced from 1954 to 1969 and, with a few changes to 1975.  It became the all-time best seller for Willis Chalmers. The HD-21 was a bit cheaper and was equipped with superior track bearings that kept out the dirt which the Caterpillar finally adopted in 1958.

This is a "make-it-yourself" kit from Wheels of Time that offers high-quality material and a bright, working addition to layouts.  D-21 Crawler Kit is especially made like how they look and are handled on railroad flatcars. The Crawler Kit consists of a three piece (body, right side and left side treads) made of high quality urethane resin castings in neutral gray. Exhaust pipe is made of 3D printed acrylic.  Assembly is required!
