Versions

* D5 (9M) was originally built in 1939, with only 46 built. It was a cross between the D4 chassis and the 6-cylinder D6 D4600 engine. * D5 - reintroduced in 1967. * D5B - 1977 * D5 SA - Special Application agricultural tractor * D5H an elevated sprocket model introduced in 1985. * D5H LGP - Low ground pressure version with wide & long tracks, for soft ground * D5K - current version * D5C 1992-2002 non elevated sprocket * D5E 1993-1999 * d5G hydrostatic drive 2001- * D5H larger version D5 elevated sprocket 1986-1996 * D5M larger versionD5 elevated "high" sprocket 1996-2003 * D5N larger version elevated sprocket 2003- * D5 (no letter designation) current as of 2021 Over the years, Caterpillar often built different series of D5s at the same time, often with a lighter version having more in common with the smaller D3 and D4 tractors, and a larger version more akin to the much larger D6. Usually, the differentiation had to do with whether or not the machine incorporated an elevated or high sprocket drive. And later, this also determined the type of transmission used, with the smaller series using a hydrostatic drive and the larger version typically having a Power-Shift transmission. These varying series have created some confusion with lineage, as the letter designation does not always correspond to when the model of machine was introduced. For example, the D5H came out years before the D5C. Interestingly, Caterpillar has now turned to a straight number designation (no letters) for all of its new track-laying tractors - starting, for the first time, with the D-1 and going all the way up to the D-11, with consistent size and weight breaks between each model. This new designation has now put the current D5's weight at close to . This is a considerable increase over any previous D5 models. The heavier, elevated versions of these could weigh . at most, or as little as . for some of the lighter series, such as the D5C. Consequently the all-new D5 is much larger than any of the earlier versions.
