Claas Challenger E – Caterpillar rubber-track crawler tractors distributed by Claas from 1997 to 2002: six-cylinder engines up to 306 kW, 65 E to 95 E models
Claas Challenger E denotes the rubber-tracked Challenger crawler tractors that Claas distributed in Europe between 1997 and 2002.

The register holds 4 versions rated at 231 to 306 kW (310 to 410 hp), with six-cylinder engines of a uniform 10,300 cm³, at a weight of 15,186 kg. Length is 5,944 mm, width 2,985 mm and height 3,668 mm; engine speed is 2,100 rpm, with PTO output ranging from 270 to 322 hp.
With their rubber-track undercarriage, the Challenger E models achieved a large ground-contact area at low ground pressure, giving them an advantage over wheeled standard tractors for heavy tillage on large arable land. They targeted large operations with high draft-force needs for cultivators, ploughs and large seeding equipment.
When buying used, these crawler tractors call for checking the condition and tension of the rubber tracks, the bogie wheels and drive sprockets, and the engine and injection system of the Caterpillar unit above all. The hydraulic system and PTO clutch should be checked for leaks and wear; undercarriage spare parts are specialised and run through dealers focused on crawler tractors.

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.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
