Caterpillar mining – other models: the collective page of dozers outside the named ranges, from the D3 to the D11 and the 797 haul truck: the number as size class, LGP for wide tracks, XL for long undercarriage
This page gathers the Caterpillar dozers and mining machines the register could not assign to a named range – the machines with which the company from Peoria, Illinois, began in 1925: Benjamin Holt's crawler tractors gave the company its name, and the dozer remained its core product. The type logic: D marks the dozer, the number the size class – D3 and D4 the small dozers around 8 t, D5 and D6 the mid-range, D7 and D8 the heavy ones, D9, D10 and D11 the mining dozers of over 100 t – the letters B to T the generations since the 1970s (D6D, D6H, D6R, D6T), LGP the swamp version with wide tracks (Low Ground Pressure), XL the long undercarriage, SA the version with special attachments, WH the landfill version (Waste Handler) and CD the version with Carrydozer blade; the K and K2 models are the small dozers of the 2010s. The 797 is Caterpillar's largest haul truck with about 400 tonnes payload. The engines are throughout Caterpillar's own: 3204 and 3304 in the small, 3306 in the mid-range, 3408 and C series in the heavy dozers and the 24-cylinder 3524 in the 797.

Caterpillar is the world's largest construction-equipment maker and in dozers the reference against which Komatsu, Liebherr and John Deere are measured; the D6 is the most-built dozer in history, the D11 the largest series-built.
On used dozers, operating hours, undercarriage (tracks, rollers, sprockets and track tension – the most expensive item), transmission and steering clutches or differential steering, blade and ripper, hydraulics and cooling count; parts run through the dense Cat dealer network.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
