Amazone’s Catros XL 2TS is its answer for farmers wanting to disc at depths down to 16cm. The 4.0m to 6.0m range is only sold in a semi-mounted format, and we tried the 6.0m model on some chitted oilseed rape stubble

Amazone views the Catros XL as a supplement to its wide range of compact disc harrows. Indeed, the company now has four different model ranges: the Catros with 460mm discs for shallow straw incorporation; the Catros+ armed with 510mm discs; and the established Certos whose 660mm discs are for leafy work and coping with plenty of residue.
