This article presents a proposal of a simple mathematical model for minimisation of the production of extraneous substances as a function of the rate of operation performance of a production system. The model is then verified by operation tests of the Terri 2040 clam bunk skidder and by determining the system's optimal rate of performance from the point of view of production of SO₂, HC and NO_x emissions. The operation tests conducted to verify the mathematical model have confirmed that conditions can be determined for the production system at which it produces minimum emissions. Min. values of SO₂, and HC were achieved at approximately the same rate of performance of the clam bunk skidder. Minimum values of NO_x were achieved at significantly higher rate of performance of the equipment. At the calculated optimal rate of operating performance of the Terri 2040 clam bunk skidder, the values of the produced emissions were determined per m³ of timber: SO₂ = 1.00035 g/m³, HC = 7.796 g/m³ and NO_x = 0.277 g/m³.
