CLAAS adds two new track widths

Narrow and wider profiles to inject even more versatility into the farming equation

German firm CLAAS has added two new track widths for its AXION TERRA TRAC, the world’s only full-suspension half-track tractor.

In addition to the existing 635mm and 735mm widths, the crawler tracks are now available in 457mm and 890mm profiles.

“The narrow tracks are ideal for row crops, while the wider width delivers even better traction and flotation in heavy operating conditions or delicate pastures,” said CLAAS Harvest Centre Product Manager – CLAAS High Horsepower Tractors, James Harrison.

“These additions mean AXION TERRA TRAC is equally at home spreading, mowing or hauling chaser bins as it is performing heavy draught work, such as cultivation and seeding.”

Introduced in 2019, the AXION 960 TERRA TRAC (445hp) and AXION 930 TERRA TRAC (355hp) are based on the same platform as the popular AXION 900 series but are fitted with fifth-generation crawler units on the rear axle.

“This concept provides the best of both worlds,” James said.

“You’ve got the improved traction and reduced soil compaction from the tracks, while the front wheels make it easy to steer just like a conventional tractor.”

CLAAS claims the technology delivers 15 per cent more traction, 35 per cent more footprint and up to 50 per cent less ground pressure compared to a wheeled tractor.

Each friction drive unit comprises an oversized drive wheel, two roller wheels, an idler wheel and an automatic tensioning cylinder.

The drive and idler wheels are designed to be self-cleaning and to reduce the build-up of heat. The rollers have independent suspension and up to 120mm of travel.

In addition, each assembly can pivot up to 23 degrees longitudinally.

“Combined with the long wheelbase, this design ensures each track remains in full contact with the ground in all operating conditions,” Harrison said.

“Between the front axle suspension, four-point cab suspension and the suspended TERRA TRAC unit, this is arguably the most comfortable tractor on the market.”

The driver can choose between three steering modes or adjust the tractor’s ground clearance by up to 120mm to match the height of the tractor to the implement.

“An intelligent drive control system provides a relatively tight turning circle of just under eight metres,” Harrison said.

“With a maximum gross weight of 22 tonnes, a three-metre width – even with the widest tracks – and a 40km/h transport speed, this tractor is 100 per cent roadworthy.”

CLAAS has manufactured more than 35,000 TERRA TRAC units since 1997.
