Caterpillar D3C — the smallest dozer in the C-series line
At 52 kW, 7.0 to 8.6 tonnes operating weight and 5.0 to 5.2 litres of displacement, the D3C is the smallest class in Caterpillar's C-series dozer programme. Six live models are on record in the database, differing mainly by suffix: D3C Series II and Series III, plus the LGP (Low Ground Pressure) and XL wide/narrow track variants.

These suffixes mark technical revision steps within the same base machine. None of the sources checked offer reliable figures on the exact market introduction or on predecessor/successor models outside the C-series, so year figures are deliberately left out here.
The D3C serves as a compact dozer for smaller earthworks sites, in grounds maintenance, and anywhere the heavier D5-through-D9 classes would be too large and too costly to run.
For a used machine in this class, the condition of the track chain links, rollers and final drives matters most. The LGP variant is worth an extra look at its wider but more delicate track shoes.
In short: the D3C is Cat's entry class among C-series dozers, built as Series II and Series III and in standard, LGP and XL form.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
