The company said that the sulphur tolerance kit was intended to provide options to operators and dealers who may ultimately sell Tier 4 powered equipment in the used market, providing greater flexibility in the regions they deliver the equipment. The kit includes new engine calibrations and hardware.

Hugh Foden, Cummins’ executive director off-highway business, said: "The introduction of the Sulphur Tolerance Kit allows customers to sell used Tier 4-powered machines into a non-emissionised country – helping to retain its resale value and ensuring that the next owner will experience the reliability and durability."
